00:00:41.256 --> 00:00:43.018
good evening ladies and

I'm in my happy place
00:00:56.883 --> 00:00:58.524
you've been busy you've
00:00:58.564 --> 00:01:00.685
been in the shop I have
00:01:00.804 --> 00:01:02.466
I've been doing so many fun
00:01:02.485 --> 00:01:03.826
things in the shop it's
00:01:03.845 --> 00:01:06.527
been great it's uh I know
00:01:07.028 --> 00:01:08.808
did you drop that video
00:01:08.888 --> 00:01:10.328
today or was it yesterday
00:01:11.817 --> 00:01:13.540
which one on the pea shooter
00:01:13.900 --> 00:01:14.801
the pea shooter that was
00:01:14.840 --> 00:01:17.644
yesterday okay yeah yeah I
00:01:17.724 --> 00:01:19.605
saw it uh I saw it this
00:01:19.766 --> 00:01:20.986
morning when I was logging
00:01:21.046 --> 00:01:22.727
in to make sure I scheduled
00:01:22.768 --> 00:01:25.990
this show tonight it's like
00:01:26.412 --> 00:01:27.352
yeah the pea shooter has
00:01:27.373 --> 00:01:28.853
been getting some love uh
00:01:29.355 --> 00:01:30.436
little bits here and there
00:01:30.475 --> 00:01:31.477
because that's really what
00:01:31.496 --> 00:01:33.739
I've had time for and you know you can
00:01:34.671 --> 00:01:35.471
have ten minutes here,
00:01:35.512 --> 00:01:36.231
fifteen minutes there,
00:01:36.251 --> 00:01:38.093
and get a lot done on CAD designs.
00:01:38.733 --> 00:01:39.834
And then you throw it on the
00:01:39.875 --> 00:01:40.936
printer and walk away.
00:01:41.436 --> 00:01:43.016
And then you come back and realize, oh,
00:01:43.677 --> 00:01:44.578
I measured that wrong.
00:01:45.799 --> 00:01:46.540
Make a revision,
00:01:46.579 --> 00:01:48.021
throw it back on the printer, walk away.
00:01:48.822 --> 00:01:50.483
So a lot of that.
00:01:50.703 --> 00:01:52.084
There's just been a lot of
00:01:52.123 --> 00:01:53.625
really fun details going on.
00:01:53.844 --> 00:01:54.585
The Peashooter,
00:01:55.426 --> 00:01:57.867
having a lot of fun dolling
00:01:57.908 --> 00:01:58.948
that airplane up and
00:01:58.989 --> 00:02:01.471
getting it ready for CEF in late April.
00:02:01.590 --> 00:02:02.772
It's going to be a really fun event.
00:02:03.603 --> 00:02:06.566
Yeah, she's looking real nice.
00:02:07.927 --> 00:02:09.609
I have a whole box full of
00:02:09.649 --> 00:02:11.110
Dubrow hardware to throw on
00:02:11.151 --> 00:02:11.950
that thing yet,
00:02:12.031 --> 00:02:14.954
so stay tuned for that for sure.
00:02:15.634 --> 00:02:18.197
It's going to be a big challenge.
00:02:19.858 --> 00:02:21.019
Get all of that on the plane.
00:02:23.469 --> 00:02:23.949
I like it.
00:02:24.350 --> 00:02:24.871
I like it.
00:02:25.931 --> 00:02:27.954
If you guys are just tuning in,
00:02:28.313 --> 00:02:29.735
drop in the chat where you
00:02:29.775 --> 00:02:31.097
guys are tuning in from.
00:02:32.478 --> 00:02:33.658
I know I've seen
00:02:35.411 --> 00:02:37.252
Uh, we've got South Dakota, West Virginia,
00:02:37.292 --> 00:02:39.953
Missouri, Daytona beach or Daytona,
00:02:39.992 --> 00:02:43.334
Florida, Mesa, Arizona, Brooklyn, Ohio,
00:02:43.394 --> 00:02:45.055
Farmington, New Mexico, St.
00:02:45.094 --> 00:02:46.995
Germain, France, France.
00:02:47.275 --> 00:02:48.156
That's the guy in the middle
00:02:48.195 --> 00:02:49.036
of the night for you.
00:02:49.075 --> 00:02:49.656
Go to bed.
00:02:50.596 --> 00:02:52.016
It'll be on YouTube in the morning.
00:02:54.217 --> 00:02:57.058
Uh, Princeton, West Virginia, Sheboygan,
00:02:58.498 --> 00:02:59.598
uh, Des Moines, Iowa.
00:03:00.039 --> 00:03:00.960
So, uh,
00:03:01.000 --> 00:03:02.240
we love seeing where everybody's
00:03:02.280 --> 00:03:03.080
tuning in from.
00:03:03.360 --> 00:03:04.040
Um,
00:03:04.377 --> 00:03:06.078
I'm going to drop a link to
00:03:06.497 --> 00:03:09.219
Joshua's YouTube channel
00:03:11.061 --> 00:03:11.961
for you guys to go check
00:03:12.062 --> 00:03:14.103
out all the cool stuff he's been doing.
00:03:14.143 --> 00:03:15.304
We were just talking about
00:03:17.444 --> 00:03:18.385
all the cool stuff he's
00:03:18.445 --> 00:03:20.907
been putting up as of recently.
00:03:25.509 --> 00:03:26.350
I know we're going to talk
00:03:26.390 --> 00:03:29.812
some iriglass and epoxy this evening.
00:03:30.514 --> 00:03:31.253
Yeah, we are.
00:03:32.435 --> 00:03:32.794
We are.
00:03:33.159 --> 00:03:33.419
Well,
00:03:35.381 --> 00:03:38.480
I wanted to have this episode mostly
00:03:38.521 --> 00:03:41.981
because I feel like pretty
00:03:42.021 --> 00:03:44.943
much every time I encounter
00:03:45.242 --> 00:03:48.183
someone who's never played
00:03:48.223 --> 00:03:50.044
with epoxy and fiberglass before,
00:03:50.504 --> 00:03:51.705
they think it's like this
00:03:51.925 --> 00:03:54.765
voodoo magic that they
00:03:54.786 --> 00:03:56.866
can't possibly wrap their minds around.
00:03:58.800 --> 00:04:00.161
If you've ever done paper mache,
00:04:00.480 --> 00:04:01.741
it's literally like that,
00:04:01.822 --> 00:04:03.043
only using different stuff.
00:04:04.524 --> 00:04:06.286
Really, it's quite that simple.
00:04:06.825 --> 00:04:10.649
You've got the glue or the flour and water,
00:04:12.490 --> 00:04:14.491
and you've got the liquid aspect,
00:04:14.611 --> 00:04:16.833
and then you've got the substrate aspect.
00:04:17.293 --> 00:04:17.954
So whether you're using
00:04:17.994 --> 00:04:20.536
tissue paper or newspaper
00:04:20.836 --> 00:04:25.199
or fiberglass cloth, it's the same idea.
00:04:27.079 --> 00:04:28.901
Same thing like if you go to
00:04:28.920 --> 00:04:30.521
do paper mache and you
00:04:30.560 --> 00:04:31.802
apply some of that glue or
00:04:31.822 --> 00:04:32.802
flour water or whatever,
00:04:32.822 --> 00:04:34.302
you want to make sure it's nice and wet.
00:04:34.802 --> 00:04:36.103
Same thing with the fiberglass.
00:04:36.124 --> 00:04:37.244
Make sure it's nice and wet
00:04:37.384 --> 00:04:38.064
all the way through.
00:04:38.504 --> 00:04:39.605
You can see where it's wet
00:04:39.625 --> 00:04:40.466
and you can see where it's
00:04:40.505 --> 00:04:41.826
dry and you just apply a
00:04:41.886 --> 00:04:43.547
little bit more or squish things around,
00:04:43.607 --> 00:04:45.588
rub it with your hand.
00:04:46.108 --> 00:04:48.848
It's really very, very approachable.
00:04:49.028 --> 00:04:51.709
It's just a little more messy.
00:04:52.089 --> 00:04:53.670
Requires a little bit more finesse.
00:04:54.524 --> 00:04:56.345
And sometimes it just needs
00:04:56.365 --> 00:04:57.425
a little bit of a guiding
00:04:57.466 --> 00:05:01.428
hand and perhaps a little
00:05:01.468 --> 00:05:03.009
sense of adventure on your side.
00:05:04.990 --> 00:05:06.932
Yeah, I can see.
00:05:07.793 --> 00:05:09.494
I think the epoxy factor is
00:05:09.555 --> 00:05:13.476
what's most intimidating to
00:05:13.497 --> 00:05:14.077
a lot of guys.
00:05:14.377 --> 00:05:19.100
And it's not just in model aviation.
00:05:19.781 --> 00:05:21.822
I've seen it in other aspects, too.
00:05:22.831 --> 00:05:25.672
I got a big fiberglass epoxy
00:05:25.732 --> 00:05:27.151
project this summer I'm doing,
00:05:27.211 --> 00:05:30.372
so we'll see how that goes.
00:05:30.432 --> 00:05:30.971
Well, good luck.
00:05:32.853 --> 00:05:33.572
It'll be interesting.
00:05:35.452 --> 00:05:37.374
Well, I mean, we can dig right in,
00:05:37.394 --> 00:05:38.473
but I did want to ask you
00:05:38.694 --> 00:05:41.434
one question before we get into this.
00:05:41.754 --> 00:05:44.814
Is that all right?
00:05:44.855 --> 00:05:45.175
Sure.
00:05:45.194 --> 00:05:47.514
All right.
00:05:47.535 --> 00:05:48.714
Putting you on the spot here.
00:05:49.156 --> 00:05:52.036
So you're going to Toledo, right?
00:05:53.146 --> 00:05:53.365
Yes.
00:05:54.567 --> 00:05:56.307
Dubrow will be at the Toledo
00:05:56.348 --> 00:05:59.269
show and the Dayton
00:05:59.649 --> 00:06:01.149
Modelrama show as well.
00:06:01.449 --> 00:06:02.130
All right.
00:06:03.350 --> 00:06:05.853
So you've said previously
00:06:06.372 --> 00:06:09.334
that you're on the lookout for a model.
00:06:09.353 --> 00:06:10.975
I am.
00:06:11.014 --> 00:06:11.435
You are.
00:06:12.415 --> 00:06:18.579
What model are you on the lookout for?
00:06:18.619 --> 00:06:20.279
More than likely, it's going to be a Cobb.
00:06:20.300 --> 00:06:20.560
Okay.
00:06:20.620 --> 00:06:22.281
Mm-hmm.
00:06:23.925 --> 00:06:27.586
Joshua's disappointed in me, I know.
00:06:28.127 --> 00:06:29.327
No, I'm not disappointed.
00:06:29.468 --> 00:06:30.988
Cubs are really good planes.
00:06:32.449 --> 00:06:33.930
Make sure you're ready on that rudder,
00:06:34.110 --> 00:06:34.610
young man.
00:06:37.992 --> 00:06:38.172
Now,
00:06:38.471 --> 00:06:42.374
the reason that I ask is this is a
00:06:42.434 --> 00:06:43.595
topic of conversation that
00:06:43.634 --> 00:06:45.196
I'd like to have in a future week.
00:06:46.115 --> 00:06:48.076
You have to go into these
00:06:48.336 --> 00:06:50.098
swap meets knowing what you want.
00:06:50.577 --> 00:06:51.999
You can't just go there and
00:06:52.038 --> 00:06:53.379
be surprised by...
00:06:54.983 --> 00:06:55.423
Something.
00:06:56.024 --> 00:06:57.865
Because more often than not,
00:06:57.966 --> 00:06:58.927
if you do that,
00:06:59.026 --> 00:06:59.766
I'm not saying that it
00:06:59.807 --> 00:07:01.327
doesn't happen or shouldn't happen,
00:07:01.427 --> 00:07:03.228
I'm saying that more often than not,
00:07:03.309 --> 00:07:05.370
it's not going to happen.
00:07:06.011 --> 00:07:08.173
A lot of the stuff at this is, frankly,
00:07:08.192 --> 00:07:08.733
is junk.
00:07:08.752 --> 00:07:10.434
Every once in a while you
00:07:10.473 --> 00:07:13.235
can find some real diamonds in the rough,
00:07:13.836 --> 00:07:14.896
and I certainly have.
00:07:15.987 --> 00:07:17.689
But you really need to go in
00:07:18.069 --> 00:07:19.151
with your eyes open and
00:07:19.190 --> 00:07:21.932
focused on what are you looking for?
00:07:21.992 --> 00:07:22.853
Have a plan.
00:07:24.214 --> 00:07:27.076
And then we can talk more about this later,
00:07:27.197 --> 00:07:29.620
but I thought I would
00:07:30.040 --> 00:07:31.680
initiate that conversation
00:07:31.841 --> 00:07:33.642
now and have people start
00:07:33.802 --> 00:07:35.043
thinking about it so that
00:07:35.064 --> 00:07:36.444
we can have some more
00:07:36.545 --> 00:07:37.805
interactive discussion with
00:07:37.865 --> 00:07:38.807
people in the future.
00:07:38.906 --> 00:07:39.367
Sound good?
00:07:39.548 --> 00:07:39.848
Sure.
00:07:40.067 --> 00:07:41.689
Yeah, I like it.
00:07:41.769 --> 00:07:42.170
I like it.
00:07:44.189 --> 00:07:45.911
I know there's already been
00:07:46.211 --> 00:07:47.331
quite a few swap meets
00:07:47.370 --> 00:07:49.471
already going on around the country.
00:07:50.372 --> 00:07:53.033
I saw the guys at RC Roundtable.
00:07:54.314 --> 00:07:56.456
They were at some shows.
00:07:56.995 --> 00:07:58.057
I don't think it was last weekend.
00:07:58.096 --> 00:08:00.137
I think it was the weekend before.
00:08:00.759 --> 00:08:01.899
It seems like every other
00:08:01.939 --> 00:08:02.620
weekend they're going.
00:08:02.639 --> 00:08:03.399
Yeah, yeah, yeah.
00:08:06.639 --> 00:08:08.641
But there are boats there
00:08:08.680 --> 00:08:09.562
that I'm just like, oh,
00:08:09.581 --> 00:08:10.862
that would be really fun to
00:08:11.163 --> 00:08:12.283
sort of play with that.
00:08:12.322 --> 00:08:13.283
That'd be kind of cool.
00:08:13.303 --> 00:08:15.125
And that's kind of the surprise factor.
00:08:16.685 --> 00:08:18.547
But then there is one model
00:08:18.586 --> 00:08:21.267
that I'm kind of on the lookout for.
00:08:21.387 --> 00:08:24.629
What are you on the lookout for?
00:08:24.670 --> 00:08:27.732
So it's a Fairchild PT-Nineteen.
00:08:28.411 --> 00:08:29.673
Okay.
00:08:29.713 --> 00:08:30.512
Guilty as charged.
00:08:30.973 --> 00:08:31.334
Why?
00:08:31.413 --> 00:08:33.094
It's not that particularly
00:08:33.174 --> 00:08:34.794
of an interesting airplane.
00:08:34.914 --> 00:08:35.875
It's a trainer aircraft.
00:08:37.863 --> 00:08:39.403
So the interesting part for
00:08:39.443 --> 00:08:40.403
me is the history.
00:08:40.865 --> 00:08:42.586
The history is that those
00:08:42.625 --> 00:08:43.485
airplanes were made
00:08:43.546 --> 00:08:44.626
literally half an hour away
00:08:44.647 --> 00:08:48.028
from me in Hagerstown, Maryland.
00:08:48.109 --> 00:08:49.490
Fairchild Aircraft Company
00:08:49.529 --> 00:08:51.552
was made in Maryland and
00:08:52.532 --> 00:08:54.153
that's my interest is the history.
00:08:54.212 --> 00:08:55.134
I want to explore the
00:08:55.173 --> 00:08:56.695
history more of the
00:08:56.715 --> 00:08:58.475
Fairchild PT-Nineteen.
00:09:00.318 --> 00:09:01.899
so yeah I know that there's
00:09:02.179 --> 00:09:03.782
uh an old great plains one
00:09:03.861 --> 00:09:04.662
and that there's an old
00:09:04.701 --> 00:09:05.643
hangar nine one they're
00:09:05.763 --> 00:09:07.964
both pretty big like in the
00:09:08.044 --> 00:09:09.225
eighty nine ninety inch
00:09:09.325 --> 00:09:11.407
category uh something like
00:09:11.447 --> 00:09:14.009
that so uh that's that's
00:09:14.089 --> 00:09:15.549
really what I'm looking for
00:09:15.830 --> 00:09:17.451
something in that area
00:09:17.490 --> 00:09:18.552
because I want to do some
00:09:18.572 --> 00:09:19.873
really fun details I want
00:09:19.893 --> 00:09:21.634
to explore this model and
00:09:22.254 --> 00:09:23.274
really get to know it
00:09:23.836 --> 00:09:26.477
rather intimately and play
00:09:26.498 --> 00:09:29.158
with landing gear configurations and and
00:09:30.220 --> 00:09:31.860
Look at the engine
00:09:31.880 --> 00:09:33.221
configurations and detail
00:09:33.241 --> 00:09:34.442
the cockpit and stuff like
00:09:34.602 --> 00:09:35.702
that kind of thing.
00:09:35.763 --> 00:09:36.683
Yeah, exactly.
00:09:37.344 --> 00:09:40.686
I want to explore this weird
00:09:40.765 --> 00:09:44.028
kind of goofy looking trainer.
00:09:45.208 --> 00:09:46.690
I've heard that the models
00:09:46.789 --> 00:09:49.490
all fly quite gentle and
00:09:49.530 --> 00:09:50.351
that's fine with me.
00:09:50.412 --> 00:09:51.812
I'm not looking for anything
00:09:51.832 --> 00:09:52.673
too aerobatic.
00:09:52.773 --> 00:09:54.433
I really just want to have a
00:09:54.474 --> 00:09:57.416
lot of fun playing with
00:09:57.456 --> 00:09:59.197
details and learning the history.
00:10:01.669 --> 00:10:03.511
RC Barn said he's got three
00:10:03.552 --> 00:10:05.052
tables at Toledo this year.
00:10:05.092 --> 00:10:06.433
There's always diamonds in
00:10:06.453 --> 00:10:07.193
the rough there.
00:10:07.875 --> 00:10:08.434
Yeah.
00:10:08.495 --> 00:10:11.738
Which we did see a few last year, I think.
00:10:11.798 --> 00:10:12.158
We did.
00:10:12.739 --> 00:10:14.139
We did, yeah.
00:10:14.159 --> 00:10:18.062
DynamicRC says the Dynafly PTs fly nice.
00:10:18.143 --> 00:10:19.764
He's had five now.
00:10:19.904 --> 00:10:20.585
Why five?
00:10:20.924 --> 00:10:21.826
Why not only one?
00:10:21.846 --> 00:10:25.528
Because...
00:10:26.706 --> 00:10:28.288
down is up and up is
00:10:28.327 --> 00:10:35.455
expensive right yes just
00:10:35.475 --> 00:10:36.596
poking fun a little there
00:10:36.635 --> 00:10:38.157
dynamic rc appreciate your
00:10:38.197 --> 00:10:40.960
comments now I'll look into
00:10:40.980 --> 00:10:41.919
the dynaflight but really
00:10:41.961 --> 00:10:42.780
I'm looking to pick up
00:10:42.841 --> 00:10:43.822
something just because it's
00:10:43.861 --> 00:10:46.865
fun that way um but yeah
00:10:46.884 --> 00:10:48.066
we'll see if anything turns
00:10:48.125 --> 00:10:49.767
out this year I will be at
00:10:49.826 --> 00:10:51.568
the lebanon rc expo in
00:10:51.609 --> 00:10:53.591
lebanon pennsylvania I have a table there
00:10:54.691 --> 00:10:56.351
I will be there with our
00:10:56.652 --> 00:10:59.254
friend Anthony from FPV Builds RC,
00:10:59.293 --> 00:11:00.534
who is sponsoring the event.
00:11:01.375 --> 00:11:02.576
He is a North America
00:11:02.897 --> 00:11:04.138
retailer on the East Coast
00:11:04.197 --> 00:11:06.760
for FrSky radio equipment.
00:11:07.120 --> 00:11:09.482
So it'll be fun.
00:11:09.523 --> 00:11:10.464
Sooner family said,
00:11:10.504 --> 00:11:12.205
when you're upside down, up is down.
00:11:12.985 --> 00:11:13.405
Correct.
00:11:15.528 --> 00:11:15.888
All right.
00:11:16.008 --> 00:11:17.308
So shall we get started with
00:11:17.349 --> 00:11:18.169
fiberglassing?
00:11:18.629 --> 00:11:19.250
Yes, sir.
00:11:19.291 --> 00:11:20.032
Okay.
00:11:20.111 --> 00:11:20.331
Okay.
00:11:21.322 --> 00:11:23.183
So the first thing that we
00:11:23.203 --> 00:11:24.304
have to talk about are the
00:11:24.345 --> 00:11:25.666
ingredients of the equation.
00:11:26.446 --> 00:11:30.528
So when you fiberglass,
00:11:31.288 --> 00:11:32.809
you know the answer to this, Brian.
00:11:33.591 --> 00:11:35.131
But you typically use
00:11:35.172 --> 00:11:37.533
something called an epoxy.
00:11:41.235 --> 00:11:45.798
Two trees and three dumb thumbs.
00:11:45.839 --> 00:11:46.519
Trees happen.
00:11:47.679 --> 00:11:48.100
And boy,
00:11:48.139 --> 00:11:49.520
my thumbs are getting dumber the
00:11:49.581 --> 00:11:50.562
older I get, I tell you.
00:11:54.195 --> 00:11:55.155
All right,
00:11:55.176 --> 00:11:58.515
so we had a conversation briefly,
00:11:58.556 --> 00:12:01.216
if you recall, last season about epoxy.
00:12:02.177 --> 00:12:04.476
This is Zapp Epoxy.
00:12:04.677 --> 00:12:05.857
This is their Z-Poxy.
00:12:05.878 --> 00:12:07.817
This is their finishing resin.
00:12:08.298 --> 00:12:09.077
And the reason that it's
00:12:09.118 --> 00:12:10.219
finishing resin is because
00:12:10.239 --> 00:12:12.538
you can see that it's quite
00:12:12.639 --> 00:12:14.438
thin in viscosity.
00:12:15.139 --> 00:12:16.720
It flows very, very well.
00:12:17.856 --> 00:12:19.538
The thirty minute curie epoxy,
00:12:20.340 --> 00:12:22.522
while it has a really long working time,
00:12:22.621 --> 00:12:23.763
it is quite thick.
00:12:24.344 --> 00:12:25.605
And the reason that you
00:12:25.825 --> 00:12:27.846
don't necessarily want that
00:12:28.388 --> 00:12:30.610
is because it's not going
00:12:30.649 --> 00:12:32.211
to work its way into the
00:12:32.312 --> 00:12:35.195
weave of the fiberglass.
00:12:35.835 --> 00:12:36.655
Now there are tips and
00:12:36.696 --> 00:12:38.677
tricks that you can do to thin it.
00:12:38.758 --> 00:12:39.958
You can add denatured
00:12:40.058 --> 00:12:41.461
alcohol to thin it out.
00:12:43.582 --> 00:12:45.283
But one of the big things is
00:12:45.344 --> 00:12:48.946
to try to find a dry time to do it.
00:12:49.346 --> 00:12:50.687
Thankfully the air is very
00:12:50.727 --> 00:12:52.028
dry in the winter here,
00:12:52.087 --> 00:12:53.589
relatively speaking, where I live.
00:12:54.090 --> 00:12:55.691
I have had situations where
00:12:56.370 --> 00:12:59.293
fiberglass and epoxy has flashed.
00:13:02.174 --> 00:13:03.336
It's a phenomenon where
00:13:03.596 --> 00:13:05.376
there's so much moisture in
00:13:05.437 --> 00:13:07.938
the air that it in fact
00:13:08.318 --> 00:13:11.380
separates the resin
00:13:12.062 --> 00:13:13.182
And the hardener.
00:13:13.283 --> 00:13:14.083
And the hardener.
00:13:14.764 --> 00:13:16.285
And it just, it stays sticky.
00:13:16.446 --> 00:13:19.068
It never cures.
00:13:19.109 --> 00:13:20.090
So that is a factor.
00:13:20.149 --> 00:13:21.250
Make sure that you know
00:13:21.331 --> 00:13:22.172
ahead of time that it's
00:13:22.192 --> 00:13:24.214
going to be dry or that
00:13:24.274 --> 00:13:25.195
you're going to do this in
00:13:25.215 --> 00:13:26.596
your home where you know
00:13:26.636 --> 00:13:28.278
that you can regulate the humidity.
00:13:29.960 --> 00:13:30.801
The other thing is
00:13:30.921 --> 00:13:32.783
definitely stay away in
00:13:32.822 --> 00:13:36.046
this hobby from polyester resins.
00:13:38.003 --> 00:13:38.964
So, for example,
00:13:39.024 --> 00:13:40.124
if you run down to your
00:13:40.163 --> 00:13:41.985
local hardware store, your Ace,
00:13:42.044 --> 00:13:47.006
your Maynard's or Menards, Home Depot,
00:13:47.067 --> 00:13:47.427
Lowe's,
00:13:47.927 --> 00:13:48.988
generally what you're going to
00:13:49.008 --> 00:13:50.067
find is something that's
00:13:50.288 --> 00:13:51.769
like what would be used for
00:13:51.828 --> 00:13:54.909
like boats or working with cars.
00:13:55.471 --> 00:13:56.431
And those are typically
00:13:56.530 --> 00:13:59.032
polyester resins as opposed
00:13:59.072 --> 00:14:01.452
to true epoxy resins.
00:14:03.104 --> 00:14:03.804
The reason you don't
00:14:03.845 --> 00:14:05.144
necessarily want those is
00:14:05.205 --> 00:14:07.966
because they induce more of
00:14:08.006 --> 00:14:10.668
an exothermic reaction when
00:14:10.788 --> 00:14:12.428
they are mixed with their hardener.
00:14:12.568 --> 00:14:14.750
So the chemical reaction
00:14:14.811 --> 00:14:17.312
itself generates heat and
00:14:17.392 --> 00:14:19.192
so the resin expands and
00:14:19.212 --> 00:14:21.234
then as it cools it shrinks.
00:14:21.894 --> 00:14:23.075
And so you end up having
00:14:23.174 --> 00:14:25.676
warps and little things in
00:14:25.736 --> 00:14:27.277
these kinds of applications
00:14:27.356 --> 00:14:28.298
that you end up having to
00:14:28.337 --> 00:14:30.119
do more work and sand out.
00:14:31.025 --> 00:14:32.469
Not necessarily a bad thing
00:14:32.489 --> 00:14:34.533
in some situations, but more often not,
00:14:34.633 --> 00:14:35.855
it becomes problematic.
00:14:36.375 --> 00:14:37.018
And in addition,
00:14:37.077 --> 00:14:40.403
they're far more stinky as a result.
00:14:41.801 --> 00:14:43.902
um so be aware of that
00:14:44.121 --> 00:14:45.182
especially if you're using
00:14:45.222 --> 00:14:47.224
it in enclosed space like a
00:14:47.283 --> 00:14:50.085
small garage or a room you
00:14:50.265 --> 00:14:52.366
really don't want to be
00:14:52.427 --> 00:14:53.246
messing around with this
00:14:53.287 --> 00:14:54.947
stuff and breathing all of
00:14:54.967 --> 00:14:56.208
those fumes whereas opposed
00:14:56.229 --> 00:14:58.129
to epoxy resins like stuff
00:14:58.149 --> 00:14:59.591
from zap it's really not
00:14:59.630 --> 00:15:02.231
that bad it's not a big deal um
00:15:04.975 --> 00:15:05.414
I'll tell you,
00:15:06.056 --> 00:15:08.755
using epoxy in the basement
00:15:08.855 --> 00:15:09.836
here in my home,
00:15:10.236 --> 00:15:11.177
where the furnace is
00:15:11.336 --> 00:15:12.658
literally twenty feet from me,
00:15:15.038 --> 00:15:16.019
the smell does not go
00:15:16.078 --> 00:15:17.719
anywhere outside of this basement.
00:15:19.019 --> 00:15:21.860
So, there is that.
00:15:22.320 --> 00:15:23.801
The other thing that you're going to want,
00:15:23.841 --> 00:15:25.201
the other ingredient aside
00:15:25.221 --> 00:15:28.802
from your epoxy, is your cloth.
00:15:29.302 --> 00:15:31.143
Cloth comes in a number of different
00:15:31.831 --> 00:15:33.293
flavors, shall we say.
00:15:34.153 --> 00:15:35.755
I'm going to hold this up pretty close.
00:15:35.816 --> 00:15:37.636
Hopefully you can see this
00:15:37.756 --> 00:15:39.719
and that the camera will focus.
00:15:39.739 --> 00:15:40.200
There you go.
00:15:40.220 --> 00:15:40.720
There you go.
00:15:41.421 --> 00:15:43.623
So we have a nice weave on this fabric.
00:15:43.663 --> 00:15:44.783
It's very small.
00:15:46.345 --> 00:15:48.647
But typically when you go
00:15:48.807 --> 00:15:51.149
and buy fiberglass cloth,
00:15:51.208 --> 00:15:53.812
you buy it in what's called weight.
00:15:54.692 --> 00:15:56.173
So you have something that's like
00:15:56.946 --> 00:15:59.769
six ounces per square foot
00:15:59.869 --> 00:16:02.270
or square yard and so
00:16:02.311 --> 00:16:04.232
that's that's the weight
00:16:04.692 --> 00:16:07.154
now you can have a heavy
00:16:07.274 --> 00:16:10.437
weight cloth but this is
00:16:10.498 --> 00:16:11.538
like stuff that you would
00:16:11.578 --> 00:16:12.980
get at the hardware store
00:16:13.080 --> 00:16:15.621
right for fixing a car look
00:16:15.682 --> 00:16:19.785
at the size of the weave
00:16:19.826 --> 00:16:21.847
compared to this other stuff
00:16:24.398 --> 00:16:25.219
so really what you're
00:16:25.239 --> 00:16:27.240
looking it's a much finer
00:16:27.841 --> 00:16:30.702
weave and these are
00:16:30.763 --> 00:16:32.304
honestly about the same in
00:16:32.345 --> 00:16:35.307
terms of weight all right
00:16:35.807 --> 00:16:37.528
the difference is this
00:16:37.568 --> 00:16:39.530
stuff because of the finer
00:16:40.812 --> 00:16:42.613
weave it goes around
00:16:42.673 --> 00:16:44.534
corners much better like
00:16:44.754 --> 00:16:46.176
tight corners you can bend
00:16:46.216 --> 00:16:47.817
it around corners whereas the large stuff
00:16:48.424 --> 00:16:50.885
this stuff it does it does
00:16:50.985 --> 00:16:53.226
not want to bend hardly at
00:16:53.287 --> 00:16:55.447
all unless you do it on a
00:16:55.808 --> 00:16:58.389
bias uh brian you know what
00:16:58.429 --> 00:16:59.769
bias is right I'm assuming
00:17:02.351 --> 00:17:05.772
uh no okay so bias bias you
00:17:05.813 --> 00:17:07.273
have you have strands
00:17:07.334 --> 00:17:08.674
running horizontal and
00:17:08.755 --> 00:17:09.855
strands running vertical
00:17:09.875 --> 00:17:11.395
all right it's creating a lattice
00:17:12.384 --> 00:17:13.885
So when you go to layer,
00:17:14.125 --> 00:17:15.287
typically you want to do
00:17:15.346 --> 00:17:17.068
something at a bias.
00:17:17.189 --> 00:17:18.589
So you have the horizontal
00:17:18.671 --> 00:17:19.351
and the vertical,
00:17:19.771 --> 00:17:20.673
and you put it to a
00:17:20.732 --> 00:17:21.973
forty-five degree angle.
00:17:22.013 --> 00:17:23.214
Okay?
00:17:23.635 --> 00:17:24.817
Got it.
00:17:24.836 --> 00:17:27.019
So you can really do some
00:17:27.058 --> 00:17:29.201
good bending on the bias,
00:17:30.241 --> 00:17:31.323
but it's not going to want
00:17:31.343 --> 00:17:34.646
to bend not on the bias, right?
00:17:35.680 --> 00:17:38.743
So with the finer strands,
00:17:38.864 --> 00:17:40.306
you get much better
00:17:40.365 --> 00:17:43.049
cornering and more precise shapes.
00:17:44.291 --> 00:17:45.794
And then the lighter weight,
00:17:46.755 --> 00:17:48.176
not only does it help fill
00:17:48.217 --> 00:17:49.377
the weave of the thicker
00:17:49.419 --> 00:17:50.400
fabric underneath,
00:17:51.317 --> 00:17:53.759
uh in between but it also is
00:17:53.819 --> 00:17:56.560
able to conform to compound
00:17:56.601 --> 00:17:57.981
curves and take those
00:17:58.021 --> 00:17:59.722
corners exceptionally well
00:18:00.623 --> 00:18:02.223
so that that that is why we
00:18:02.284 --> 00:18:03.944
have the super lightweight
00:18:03.964 --> 00:18:04.805
stuff this is from our
00:18:04.845 --> 00:18:06.365
friends at deluxe materials
00:18:06.465 --> 00:18:08.287
in the uk they've sent us a
00:18:08.307 --> 00:18:09.107
whole bunch of stuff and
00:18:09.147 --> 00:18:10.608
this is their fine material
00:18:10.648 --> 00:18:12.809
and I'll try to again zoom
00:18:12.930 --> 00:18:14.911
in it's in the plastic but
00:18:14.931 --> 00:18:16.652
you should be able to see
00:18:16.832 --> 00:18:20.493
uh get my face out of here
00:18:22.775 --> 00:18:23.796
Come on.
00:18:23.875 --> 00:18:24.476
There we go.
00:18:25.896 --> 00:18:30.317
So you can see that this this weave,
00:18:30.878 --> 00:18:32.298
you can see pretty well defined,
00:18:32.398 --> 00:18:34.200
but it's very hard to see
00:18:34.220 --> 00:18:35.980
it through the camera on
00:18:36.020 --> 00:18:38.981
the fine wave stuff because it is tiny,
00:18:39.261 --> 00:18:39.883
tiny, tiny,
00:18:39.923 --> 00:18:41.163
tiny on the lightweight stuff.
00:18:41.884 --> 00:18:43.144
And that is what's going to
00:18:43.163 --> 00:18:45.025
give you your best surface finish.
00:18:45.731 --> 00:18:47.613
So usually surface finish is
00:18:47.653 --> 00:18:49.074
done after you've done all
00:18:49.115 --> 00:18:50.414
of your heavy glass work
00:18:50.536 --> 00:18:52.477
and any of your surface imperfections.
00:18:53.837 --> 00:18:55.479
This is Model Light again
00:18:55.519 --> 00:18:58.421
from our friends at Deluxe Products.
00:18:58.500 --> 00:18:59.721
It's a very lightweight
00:18:59.781 --> 00:19:01.103
filler that you can spread
00:19:01.143 --> 00:19:02.144
and kind of smooth and then
00:19:02.183 --> 00:19:03.044
you sand it back.
00:19:04.865 --> 00:19:07.186
The other thing that you can do is, again,
00:19:07.326 --> 00:19:09.128
using the power of epoxy,
00:19:09.368 --> 00:19:13.010
you can mix in epoxy with micro balloons.
00:19:13.030 --> 00:19:15.073
And these are tiny glass spheres.
00:19:16.050 --> 00:19:18.051
Um, don't want to breathe them too heavily,
00:19:19.412 --> 00:19:20.413
but you mix that up and it
00:19:20.653 --> 00:19:22.032
almost makes like a
00:19:22.192 --> 00:19:23.894
toothpaste consistency.
00:19:23.913 --> 00:19:24.614
All right.
00:19:24.794 --> 00:19:26.914
And then you can spatula
00:19:26.934 --> 00:19:30.256
that into big gaping holes or, uh,
00:19:31.096 --> 00:19:32.297
other imperfections,
00:19:32.336 --> 00:19:33.217
or even if you want to
00:19:33.257 --> 00:19:35.778
create a small filet, uh,
00:19:35.917 --> 00:19:37.679
around like an empanage or,
00:19:37.818 --> 00:19:39.499
or a wing filet, uh,
00:19:39.638 --> 00:19:41.740
anywhere you want to try to smooth out.
00:19:42.828 --> 00:19:44.089
It's a really great tool for
00:19:44.150 --> 00:19:45.171
doing that because it makes
00:19:45.230 --> 00:19:47.352
it very very hard but also
00:19:47.511 --> 00:19:48.711
the micro balloons help
00:19:48.731 --> 00:19:50.452
make it very very sandable.
00:19:51.294 --> 00:19:53.555
So you put in excess and you
00:19:53.595 --> 00:19:54.435
sand it back and we're
00:19:54.476 --> 00:19:55.276
actually going to talk a
00:19:55.296 --> 00:19:56.557
little bit more about that
00:19:56.596 --> 00:19:57.757
tonight because of the
00:19:57.797 --> 00:19:59.238
demonstration that I've got going.
00:19:59.798 --> 00:20:02.059
Questions so far?
00:20:02.932 --> 00:20:05.513
So Suter family is asking,
00:20:05.614 --> 00:20:07.055
what is the working time of
00:20:07.095 --> 00:20:09.517
the finishing resin epoxy
00:20:09.537 --> 00:20:10.116
you'll be using?
00:20:10.656 --> 00:20:11.557
Very good question.
00:20:11.597 --> 00:20:12.337
Very good question.
00:20:12.397 --> 00:20:14.259
So the finishing resin from ZAP,
00:20:14.278 --> 00:20:15.400
and this will vary from
00:20:15.440 --> 00:20:16.680
manufacturer to manufacturer.
00:20:16.720 --> 00:20:18.240
So don't be a man and not
00:20:18.280 --> 00:20:19.281
read the instructions.
00:20:19.781 --> 00:20:20.843
Read the instructions.
00:20:21.262 --> 00:20:21.482
Okay.
00:20:22.443 --> 00:20:23.585
The finishing resin from
00:20:23.625 --> 00:20:26.087
Zapp has a working time, a pot time,
00:20:26.428 --> 00:20:28.369
sometimes referred to, of about an hour.
00:20:29.530 --> 00:20:30.813
Kind of depends on the temperature.
00:20:31.232 --> 00:20:33.275
Right now it's freezing in my shop,
00:20:33.355 --> 00:20:35.637
so working time is a little bit longer.
00:20:36.397 --> 00:20:37.779
Full cure time on the box
00:20:37.799 --> 00:20:38.780
says about three hours.
00:20:39.181 --> 00:20:41.243
For me, today in the basement, four.
00:20:41.263 --> 00:20:42.244
Okay.
00:20:44.002 --> 00:20:45.864
just because it's so cold.
00:20:46.923 --> 00:20:48.484
So that is a factor as well.
00:20:48.684 --> 00:20:50.644
It can sometimes work to your advantage.
00:20:51.525 --> 00:20:52.326
In the summertime,
00:20:52.425 --> 00:20:53.046
it can work to your
00:20:53.086 --> 00:20:54.705
disadvantage or to your
00:20:54.746 --> 00:20:56.826
advantage depends on how you want.
00:20:57.707 --> 00:20:59.147
Also note that the longer
00:20:59.847 --> 00:21:02.308
working slash cure time that you have,
00:21:03.009 --> 00:21:06.069
the more brittle the fiberglass will be.
00:21:06.529 --> 00:21:10.451
So like five minute epoxy, you can almost
00:21:11.890 --> 00:21:13.510
Bend that epoxy if you
00:21:13.550 --> 00:21:15.311
create like a long roll of
00:21:15.332 --> 00:21:16.932
it or a bead of it as
00:21:16.992 --> 00:21:17.953
opposed to this stuff It's
00:21:18.114 --> 00:21:19.013
just gonna snap,
00:21:19.513 --> 00:21:20.295
you know kind of like
00:21:20.355 --> 00:21:23.376
toffee So keep that in mind too.
00:21:23.436 --> 00:21:25.076
What really helps bring
00:21:25.136 --> 00:21:28.278
things along is The the
00:21:28.318 --> 00:21:30.079
fiberglass cloth itself.
00:21:30.160 --> 00:21:31.820
That is what brings the strength.
00:21:32.080 --> 00:21:35.663
Okay, the epoxy itself Adds some strength,
00:21:35.722 --> 00:21:37.423
but really it's a binder
00:21:37.964 --> 00:21:40.066
for the fibers Okay
00:21:40.987 --> 00:21:41.366
Got it.
00:21:41.446 --> 00:21:42.968
We got two more questions.
00:21:44.088 --> 00:21:46.990
Flying Fin RC is tuning in from the UK.
00:21:47.790 --> 00:21:48.432
He's asking,
00:21:48.491 --> 00:21:49.932
is there an alternative to
00:21:49.992 --> 00:21:51.973
epoxy for covering and
00:21:52.294 --> 00:21:54.536
asked if you've used Easy Coat?
00:21:55.215 --> 00:21:55.556
Yes.
00:21:55.756 --> 00:21:56.017
Okay.
00:21:56.136 --> 00:21:56.977
So Easy Coat.
00:21:57.537 --> 00:21:58.137
Easy Coat.
00:21:58.258 --> 00:21:59.578
I have a bottle right here.
00:22:00.459 --> 00:22:00.960
Easy Coat.
00:22:01.579 --> 00:22:03.000
I have more of this stuff.
00:22:03.300 --> 00:22:04.682
Deluxe sent more of this
00:22:04.721 --> 00:22:06.202
stuff because I need to go
00:22:06.343 --> 00:22:07.983
over this stuff that I'm
00:22:08.003 --> 00:22:09.305
going to show you tonight when I'm done.
00:22:10.546 --> 00:22:12.186
So Easy Coat is essentially
00:22:12.346 --> 00:22:13.247
a sanding sealer.
00:22:13.567 --> 00:22:14.987
I've looked at the safety
00:22:15.007 --> 00:22:18.708
data sheet mostly because
00:22:18.728 --> 00:22:19.989
I'm a scientist and
00:22:20.469 --> 00:22:21.189
everything that I do
00:22:21.229 --> 00:22:22.388
revolves around being safe,
00:22:22.489 --> 00:22:23.930
whether it's pressure, chemicals,
00:22:23.990 --> 00:22:24.890
biologics, whatever.
00:22:25.670 --> 00:22:26.829
So it's essentially the same
00:22:26.849 --> 00:22:28.191
thing as sanding sealer or
00:22:28.250 --> 00:22:29.530
water-based polyurethane.
00:22:29.671 --> 00:22:30.590
It's a very specific
00:22:30.631 --> 00:22:31.932
concentration of it and it
00:22:31.951 --> 00:22:33.392
works exceptionally well
00:22:34.965 --> 00:22:38.186
You can also mix that with micro balloons.
00:22:39.107 --> 00:22:40.528
What that does is,
00:22:40.709 --> 00:22:44.611
like say you have your finish fiberglass,
00:22:44.750 --> 00:22:47.892
because of how thin Easy Coat is,
00:22:48.232 --> 00:22:49.834
you can do multiple layers
00:22:49.894 --> 00:22:51.453
of the Easy Coat and cure it out.
00:22:51.473 --> 00:22:53.075
It's really nice because it's water-based,
00:22:53.154 --> 00:22:53.414
right?
00:22:53.796 --> 00:22:54.736
You can accelerate the
00:22:54.776 --> 00:22:56.876
drying using the sun with
00:22:57.037 --> 00:22:58.258
UV as well as the heat.
00:22:58.577 --> 00:22:59.739
I use a hair dryer.
00:22:59.759 --> 00:23:01.440
I have a dedicated hair dryer in my shop.
00:23:02.000 --> 00:23:03.340
Don't use your wife's hair dryer.
00:23:03.361 --> 00:23:04.020
She will kill you.
00:23:05.362 --> 00:23:07.563
And then you can dry it and
00:23:07.583 --> 00:23:08.523
do multiple coats,
00:23:08.564 --> 00:23:10.184
like scratch it up in between coats,
00:23:10.585 --> 00:23:11.244
that kind of thing,
00:23:11.585 --> 00:23:12.826
and then sand it back.
00:23:13.645 --> 00:23:16.048
Or you can just do a thick
00:23:16.067 --> 00:23:18.888
coat of the Easy Coat mixed
00:23:19.009 --> 00:23:20.109
with Micro Balloons,
00:23:20.150 --> 00:23:21.510
and that will help fill the weave too.
00:23:22.111 --> 00:23:23.511
Sand all of that back,
00:23:24.071 --> 00:23:26.493
and then do a final finish Easy Coat,
00:23:27.594 --> 00:23:29.035
and then apply paint, all right?
00:23:30.021 --> 00:23:31.061
So there are a number of
00:23:31.122 --> 00:23:33.042
different ways that you can do a finish.
00:23:33.903 --> 00:23:36.163
Note that the Easy Coat does
00:23:36.403 --> 00:23:40.045
not add all that much strength.
00:23:40.704 --> 00:23:41.885
It will be a fairly
00:23:41.965 --> 00:23:45.406
resilient surface for accepting paint.
00:23:46.307 --> 00:23:48.847
But in terms of adding strength to a wing,
00:23:49.367 --> 00:23:50.288
it will not.
00:23:51.208 --> 00:23:53.409
Epoxy and fiberglass will.
00:23:54.619 --> 00:23:56.161
So sometimes a model is
00:23:56.201 --> 00:23:58.063
designed to be built with
00:23:58.182 --> 00:23:59.884
the epoxy and fiberglass,
00:24:00.605 --> 00:24:02.207
like if you're doing an entire wing.
00:24:03.828 --> 00:24:04.869
If that's the case,
00:24:05.470 --> 00:24:07.172
do not use easy coat because
00:24:08.700 --> 00:24:09.359
you're going to have a very
00:24:09.400 --> 00:24:11.560
sad day at one point, I promise.
00:24:11.580 --> 00:24:13.961
All right, next question.
00:24:14.643 --> 00:24:15.663
Rick Rader asked,
00:24:15.722 --> 00:24:17.163
and I think this is a great question,
00:24:17.324 --> 00:24:18.163
for strength,
00:24:18.443 --> 00:24:20.184
is it better to use multiple
00:24:20.244 --> 00:24:21.705
layers of lightweight
00:24:21.766 --> 00:24:23.567
fiberglass or use one
00:24:23.866 --> 00:24:27.627
heavier weighted fiberglass?
00:24:28.689 --> 00:24:30.049
It depends on your application.
00:24:30.069 --> 00:24:33.191
And what I mean by that is,
00:24:34.151 --> 00:24:35.672
so if you have one
00:24:36.211 --> 00:24:37.613
heavyweight fiberglass,
00:24:38.173 --> 00:24:40.194
When you go to sand that smooth,
00:24:40.335 --> 00:24:41.076
it's going to be a lot of
00:24:41.115 --> 00:24:42.076
work to get it smooth and
00:24:42.096 --> 00:24:42.977
then you're going to be
00:24:43.017 --> 00:24:43.936
left with all these little
00:24:43.997 --> 00:24:45.258
divots all over it that you
00:24:45.298 --> 00:24:51.142
eventually have to fill with more epoxy.
00:24:51.182 --> 00:24:52.521
Which is why when you do a
00:24:52.582 --> 00:24:55.183
layup in a situation where
00:24:55.203 --> 00:24:58.465
you're going to do a final paint finish,
00:24:59.271 --> 00:25:00.874
You apply the heavyweight
00:25:00.913 --> 00:25:03.436
stuff for your strength and
00:25:03.497 --> 00:25:05.157
however many layers of that
00:25:05.318 --> 00:25:08.162
per the strength that you're requesting.
00:25:08.301 --> 00:25:10.584
And then you do finish layer over top.
00:25:11.005 --> 00:25:12.125
Some people prefer to have
00:25:12.145 --> 00:25:13.686
an intermediate layer of cloth.
00:25:15.528 --> 00:25:16.711
And then it depends on like
00:25:16.990 --> 00:25:18.653
how heavy you're going for.
00:25:18.772 --> 00:25:19.713
So for example,
00:25:20.709 --> 00:25:21.869
Discus Launch Gliders.
00:25:21.990 --> 00:25:24.811
They're using Kevlar and
00:25:24.991 --> 00:25:26.732
carbon fiber cloths,
00:25:27.932 --> 00:25:29.614
not necessarily fiberglass
00:25:29.795 --> 00:25:31.655
cloths because they are stronger.
00:25:32.816 --> 00:25:35.678
But they have thinner weave
00:25:36.679 --> 00:25:39.681
with all of this fiberglass, or sorry,
00:25:39.980 --> 00:25:40.601
epoxy,
00:25:42.883 --> 00:25:45.463
because they want it as light as
00:25:45.503 --> 00:25:46.785
they possibly can.
00:25:46.805 --> 00:25:48.385
They're really threading the
00:25:48.425 --> 00:25:50.166
needle of balancing strength
00:25:51.163 --> 00:25:54.046
And lightness, okay?
00:25:54.266 --> 00:25:56.307
Mass matters on those airplanes.
00:25:56.708 --> 00:25:57.769
So if you really don't care
00:25:57.808 --> 00:25:59.750
about the mass all that much, I mean,
00:25:59.770 --> 00:26:01.511
just go with whatever your gut tells you,
00:26:01.531 --> 00:26:02.813
whatever's going to be easiest.
00:26:02.873 --> 00:26:04.013
But if you're really going
00:26:04.054 --> 00:26:04.934
for something that's going
00:26:04.954 --> 00:26:06.015
to be structural,
00:26:07.115 --> 00:26:08.537
you kind of have to be the
00:26:08.696 --> 00:26:10.778
one to do your own engineering.
00:26:11.960 --> 00:26:12.780
So ask around.
00:26:13.221 --> 00:26:13.980
So that's why I say it
00:26:14.020 --> 00:26:15.321
really depends on your application.
00:26:16.643 --> 00:26:16.963
Got it.
00:26:17.703 --> 00:26:18.144
Caught up.
00:26:18.964 --> 00:26:19.945
Okay, very good.
00:26:21.007 --> 00:26:22.028
So at this point,
00:26:22.888 --> 00:26:26.374
I am going to show you guys the wings.
00:26:26.934 --> 00:26:27.695
As you can tell,
00:26:27.895 --> 00:26:28.958
I've got a whole bunch of
00:26:28.998 --> 00:26:30.099
stuff laying around here
00:26:30.901 --> 00:26:34.726
because I've been working right now.
00:26:35.825 --> 00:26:36.965
The first thing I'll show
00:26:36.986 --> 00:26:38.749
you guys is that I do have
00:26:38.808 --> 00:26:41.692
the covers done for the wheels,
00:26:41.731 --> 00:26:42.833
which is kind of exciting.
00:26:42.873 --> 00:26:44.154
That's a big milestone.
00:26:44.194 --> 00:26:45.717
These did not exist before.
00:26:46.438 --> 00:26:48.319
The three D prints have just
00:26:48.359 --> 00:26:50.603
been an absolute joy to work with.
00:26:51.723 --> 00:26:52.525
Couldn't be happier.
00:26:53.457 --> 00:26:54.498
But where we are right now
00:26:54.718 --> 00:26:57.401
is we are trying to, if you recall,
00:26:58.442 --> 00:27:00.963
mend and integrate some
00:27:01.423 --> 00:27:02.925
additional reinforcements.
00:27:02.945 --> 00:27:04.666
I'm going to try to bring
00:27:04.686 --> 00:27:06.108
this closer to the camera.
00:27:07.930 --> 00:27:09.592
And then if you can see this
00:27:09.652 --> 00:27:10.772
little V shape.
00:27:11.813 --> 00:27:13.394
here just below my thumb
00:27:13.994 --> 00:27:15.636
where there was no material
00:27:15.856 --> 00:27:17.898
all there and that induced
00:27:17.959 --> 00:27:19.441
some cracking right here in
00:27:19.480 --> 00:27:21.742
this plastic piece and so
00:27:21.782 --> 00:27:23.144
what I'm trying to do is
00:27:23.203 --> 00:27:24.885
I'm trying to reinforce
00:27:24.905 --> 00:27:27.087
this from the backside as
00:27:27.147 --> 00:27:29.490
well as create a more scale
00:27:29.529 --> 00:27:32.032
line between here and here
00:27:32.845 --> 00:27:33.505
In addition,
00:27:33.845 --> 00:27:36.105
there's this bump ridge over
00:27:36.165 --> 00:27:37.946
here that doesn't
00:27:37.967 --> 00:27:39.386
transition well between the
00:27:39.406 --> 00:27:40.587
plastic and the wing.
00:27:41.087 --> 00:27:42.147
So I'm trying to create a
00:27:42.188 --> 00:27:44.949
transition as well.
00:27:45.068 --> 00:27:45.288
Now,
00:27:45.949 --> 00:27:48.069
what I've done is I've taken some of
00:27:48.109 --> 00:27:50.131
our fiberglass and epoxy
00:27:50.810 --> 00:27:52.112
and scratched it up on the
00:27:52.352 --> 00:27:55.492
inside of the wing.
00:27:55.512 --> 00:27:56.853
A little hard to see now
00:27:57.173 --> 00:27:59.773
that the epoxy is in there
00:27:59.794 --> 00:28:01.174
with some micro balloons to
00:28:01.214 --> 00:28:02.295
help fill things up.
00:28:04.067 --> 00:28:08.872
But I scratched up with this sixty grit,
00:28:09.272 --> 00:28:11.275
sixty grit sandpaper.
00:28:11.355 --> 00:28:12.536
Just scratched everything up,
00:28:12.576 --> 00:28:13.836
removed paint, etc.
00:28:14.557 --> 00:28:16.619
That way I could wrap this
00:28:17.180 --> 00:28:20.502
fiberglass and epoxy around the corner.
00:28:21.104 --> 00:28:23.286
That way I create a wall here.
00:28:24.586 --> 00:28:25.627
Now with this wall,
00:28:27.133 --> 00:28:29.294
There's some gaps as well,
00:28:29.334 --> 00:28:30.734
and that's why I took the
00:28:30.775 --> 00:28:32.476
remaining epoxy that was in
00:28:32.516 --> 00:28:33.257
my little cup.
00:28:33.436 --> 00:28:35.538
I'm using these tiny little
00:28:35.577 --> 00:28:38.880
paper cups that I ordered off of Amazon.
00:28:39.721 --> 00:28:41.201
They're like little medicine cups.
00:28:42.133 --> 00:28:43.354
But since they're paper, you know,
00:28:43.374 --> 00:28:44.575
they're biodegradable and I
00:28:44.615 --> 00:28:45.214
can throw them in the
00:28:45.255 --> 00:28:46.496
garbage and feel less
00:28:46.536 --> 00:28:47.656
guilty about throwing them
00:28:47.696 --> 00:28:50.558
away as opposed to plastic cup.
00:28:52.240 --> 00:28:54.501
But mix that up and then
00:28:54.541 --> 00:28:55.923
apply the glass cloth.
00:28:55.942 --> 00:28:57.943
But then I have leftover epoxy.
00:28:58.023 --> 00:28:59.684
And so I just added micro
00:28:59.704 --> 00:29:00.746
balloons to whatever was
00:29:00.806 --> 00:29:02.907
left and then filled in.
00:29:03.720 --> 00:29:05.280
this crease right here a
00:29:05.320 --> 00:29:07.402
little bit as well as this
00:29:07.461 --> 00:29:08.682
part here which I prepped
00:29:08.742 --> 00:29:11.124
by removing some of the
00:29:11.284 --> 00:29:12.625
plastic film covering
00:29:13.365 --> 00:29:14.625
roughing things up again
00:29:14.826 --> 00:29:17.126
with the sandpaper and then
00:29:17.646 --> 00:29:18.807
applying that here and
00:29:18.827 --> 00:29:19.688
there's a little bit of a
00:29:19.788 --> 00:29:21.429
blob that we can sand off
00:29:21.489 --> 00:29:24.310
right there not a huge deal all right
00:29:26.493 --> 00:29:29.156
So, first things first,
00:29:29.356 --> 00:29:31.979
this is raw from the layup.
00:29:32.098 --> 00:29:34.882
I set this on earlier this afternoon,
00:29:34.981 --> 00:29:36.163
took me ten minutes to do,
00:29:36.182 --> 00:29:39.385
it's on my lunch break, not a huge deal.
00:29:39.766 --> 00:29:41.167
The first thing I'll tell you is
00:29:41.880 --> 00:29:43.461
have a glove ready I've got
00:29:44.162 --> 00:29:45.561
a box of nitrile gloves
00:29:45.582 --> 00:29:46.663
that I like to keep around
00:29:47.423 --> 00:29:49.025
just because it's messy and
00:29:49.045 --> 00:29:50.105
you can see that I've got
00:29:50.226 --> 00:29:51.226
stuff on it and you can
00:29:51.385 --> 00:29:54.428
clean up stuff the epoxy
00:29:55.009 --> 00:29:56.750
will wipe up pretty easy
00:29:57.130 --> 00:29:58.971
with isopropyl alcohol I
00:29:59.030 --> 00:30:00.211
always have a bottle ready
00:30:00.491 --> 00:30:01.992
on my bench with isopropyl
00:30:02.073 --> 00:30:02.913
alcohol whenever
00:30:03.693 --> 00:30:08.156
I am working with epoxy.
00:30:08.217 --> 00:30:10.218
From there, yeah,
00:30:10.518 --> 00:30:11.679
you can use a paper towel
00:30:11.719 --> 00:30:14.079
to blot or wipe whatever you need.
00:30:14.820 --> 00:30:15.721
But I prefer,
00:30:15.800 --> 00:30:16.862
since we're using some pretty
00:30:16.882 --> 00:30:17.582
harsh chemicals,
00:30:18.082 --> 00:30:19.502
my fingers are my best tool
00:30:19.682 --> 00:30:20.384
most of the time.
00:30:20.844 --> 00:30:22.505
So that's why I always have a glove ready.
00:30:24.076 --> 00:30:25.477
paper towels I have a scrap
00:30:25.517 --> 00:30:26.897
paper towel here in
00:30:26.978 --> 00:30:28.339
addition I have a roll to
00:30:28.380 --> 00:30:31.501
the side so always have
00:30:31.781 --> 00:30:33.763
things ready to clean up
00:30:33.903 --> 00:30:37.007
your mess and from here
00:30:37.067 --> 00:30:38.127
we're gonna make more of a
00:30:38.167 --> 00:30:39.608
mess I have dedicated
00:30:39.689 --> 00:30:41.170
scissors for two things I
00:30:41.230 --> 00:30:43.632
have dedicated scissors for
00:30:43.751 --> 00:30:46.555
cutting my fiberglass cloth
00:30:47.714 --> 00:30:48.455
and I have these really
00:30:48.496 --> 00:30:50.617
nice Fiskars scissors that
00:30:50.637 --> 00:30:53.140
are very very sharp their only job is
00:30:53.758 --> 00:30:56.319
only job is to cut fiberglass cloth.
00:30:56.500 --> 00:30:59.061
I will not use them for anything else.
00:30:59.823 --> 00:31:01.644
If there is any sort of
00:31:02.605 --> 00:31:04.566
epoxy on the fiberglass,
00:31:05.886 --> 00:31:07.587
I use these scissors.
00:31:08.489 --> 00:31:09.869
These are my crap scissors.
00:31:10.029 --> 00:31:12.010
They're gross and falling
00:31:12.050 --> 00:31:13.853
apart and full of scuffs
00:31:13.952 --> 00:31:15.374
and acetone stains and all
00:31:15.413 --> 00:31:16.734
sorts of things because
00:31:16.775 --> 00:31:18.375
this is what will happen to
00:31:18.395 --> 00:31:19.916
the nice scissors if you don't
00:31:21.710 --> 00:31:24.491
So rather than try to trim this, you know,
00:31:24.632 --> 00:31:26.972
with a rotary tool or anything,
00:31:27.113 --> 00:31:28.114
I'm going to trim the
00:31:28.273 --> 00:31:31.015
excess right at the top of the line.
00:31:31.915 --> 00:31:34.057
So I'll hold this close again.
00:31:35.978 --> 00:31:41.000
So you can see in this area, focus, focus,
00:31:41.020 --> 00:31:41.881
focus.
00:31:41.901 --> 00:31:42.000
Okay.
00:31:45.522 --> 00:31:46.443
Mostly focused.
00:31:50.228 --> 00:31:50.647
Okay, good.
00:31:51.228 --> 00:31:53.008
So you can see there's a darkness.
00:31:53.788 --> 00:31:55.588
And that darkness is where
00:31:55.628 --> 00:31:56.528
things were wet.
00:31:57.048 --> 00:31:58.749
That's where I got the epoxy to.
00:31:59.089 --> 00:32:01.230
And you can see this is soft cloth still.
00:32:01.630 --> 00:32:02.910
Well, I want to cut this away.
00:32:03.549 --> 00:32:04.470
I want to cut this away.
00:32:05.050 --> 00:32:06.570
That way I'm not dealing
00:32:06.590 --> 00:32:07.530
with all these little
00:32:07.570 --> 00:32:09.691
threads flying around my shop,
00:32:10.211 --> 00:32:11.632
risking me breathing them in,
00:32:11.852 --> 00:32:12.771
risking them getting
00:32:12.832 --> 00:32:14.192
tangled up in things.
00:32:14.912 --> 00:32:19.553
And so I am just going to do a rough cut
00:32:21.080 --> 00:32:25.446
to get those out of my way.
00:32:25.487 --> 00:32:27.088
So you had a quick question here.
00:32:27.730 --> 00:32:30.394
Can you use epoxy resin over
00:32:30.493 --> 00:32:33.176
polyester parts or vice versa?
00:32:34.336 --> 00:32:34.997
You can.
00:32:35.657 --> 00:32:37.138
Do not trust the interface.
00:32:37.779 --> 00:32:38.480
Make sure that you're
00:32:38.519 --> 00:32:40.001
scuffing up whatever is
00:32:40.061 --> 00:32:42.604
cured out with good sandpaper.
00:32:43.585 --> 00:32:46.988
And even then, it'll stick to it,
00:32:47.127 --> 00:32:49.810
but it's best to stick with
00:32:49.851 --> 00:32:52.292
the original whatever it is,
00:32:52.333 --> 00:32:53.894
whether it's epoxy or polyester.
00:32:56.074 --> 00:33:00.914
I have heard that aging becomes an issue.
00:33:02.715 --> 00:33:04.316
They age differently and so
00:33:04.355 --> 00:33:05.976
you can have delamination
00:33:06.175 --> 00:33:09.596
at that interface.
00:33:09.696 --> 00:33:10.497
I have personally never
00:33:10.537 --> 00:33:12.417
experienced it because I
00:33:12.557 --> 00:33:14.617
always use epoxy.
00:33:14.657 --> 00:33:18.078
I never use polyester resin.
00:33:18.118 --> 00:33:18.538
Alright,
00:33:18.558 --> 00:33:22.660
so from here I am going to take my
00:33:22.740 --> 00:33:23.400
rotary tool
00:33:25.757 --> 00:33:28.999
And plug it in.
00:33:29.038 --> 00:33:31.119
And I'm going to do a trim
00:33:33.340 --> 00:33:34.342
roughly where I need it.
00:33:46.828 --> 00:33:48.269
I am intentionally keeping
00:33:48.309 --> 00:33:50.151
this slow so that if I slip,
00:33:50.711 --> 00:33:51.611
I'm going to do a minimal
00:33:51.671 --> 00:33:53.031
damage to the airplane.
00:33:57.208 --> 00:34:03.869
All right.
00:34:06.369 --> 00:34:09.050
Quick work of that so we can
00:34:09.110 --> 00:34:10.371
remove those pieces and
00:34:10.431 --> 00:34:11.552
throw them in the garbage.
00:34:13.251 --> 00:34:17.313
Next thing I need is... Oh,
00:34:17.454 --> 00:34:18.773
it's over here on the shelf.
00:34:20.494 --> 00:34:22.135
Hey, Brian, can we give one of these away?
00:34:24.425 --> 00:34:25.706
We absolutely can.
00:34:26.567 --> 00:34:28.248
Okay, cool.
00:34:28.568 --> 00:34:29.929
Can I ask a question for
00:34:29.969 --> 00:34:30.869
everybody to answer?
00:34:31.391 --> 00:34:31.510
Yes.
00:34:31.530 --> 00:34:32.731
So you can give one of those away?
00:34:33.251 --> 00:34:33.632
Yes.
00:34:34.592 --> 00:34:37.255
Okay.
00:34:39.677 --> 00:34:40.797
What North American
00:34:40.838 --> 00:34:41.898
prototype was the
00:34:42.039 --> 00:34:46.202
originator of the AT-Six Texan?
00:34:46.262 --> 00:34:51.726
Go.
00:34:51.746 --> 00:34:53.708
Question is, what North American...
00:34:54.710 --> 00:34:55.670
the aviation company,
00:34:55.730 --> 00:34:56.650
what North American
00:34:56.710 --> 00:34:58.351
prototype was the
00:34:58.471 --> 00:35:01.512
originator of the AT-Six Texan?
00:35:05.012 --> 00:35:07.472
It's two letters hyphenated
00:35:08.492 --> 00:35:12.853
with two numbers.
00:35:12.873 --> 00:35:17.875
We got NA-sixteen, BT-thirteen.
00:35:21.976 --> 00:35:24.317
NA-sixteen is correct.
00:35:26.836 --> 00:35:28.938
The NA-XVI prototype.
00:35:29.398 --> 00:35:32.199
So a quick little history on this.
00:35:32.280 --> 00:35:35.981
The NA-XVI prototype was
00:35:36.161 --> 00:35:39.364
modified into the NA-XVI,
00:35:39.943 --> 00:35:41.545
which was then the original
00:35:41.605 --> 00:35:43.405
submission to the United
00:35:43.445 --> 00:35:45.547
States Army Air Corps in
00:35:51.213 --> 00:35:53.034
A contestant in the Basic
00:35:53.275 --> 00:35:56.876
Combat Aircraft Competition.
00:35:57.717 --> 00:35:58.978
Alright, so there you go.
00:35:59.277 --> 00:36:00.798
There you go, Ryan.
00:36:00.818 --> 00:36:02.139
Ryan, send us an email.
00:36:02.440 --> 00:36:04.681
Orders at Dubro.com with
00:36:04.701 --> 00:36:06.081
your shipping address and
00:36:06.561 --> 00:36:08.722
we'll get you some quick
00:36:08.822 --> 00:36:10.884
hand sanders sent out tomorrow.
00:36:10.943 --> 00:36:13.545
Nice.
00:36:13.565 --> 00:36:18.666
The next question is not as easy.
00:36:18.726 --> 00:36:20.007
I did my homework for this one.
00:36:22.974 --> 00:36:24.356
So everybody have Google on
00:36:24.396 --> 00:36:25.617
cue for later in the show.
00:36:25.637 --> 00:36:26.077
Seriously.
00:36:27.018 --> 00:36:27.619
It's a good one.
00:36:27.898 --> 00:36:28.380
It's a good one.
00:36:28.460 --> 00:36:28.780
All right.
00:36:28.840 --> 00:36:29.621
Back to the plane.
00:36:30.280 --> 00:36:30.981
Back to the plane.
00:36:31.001 --> 00:36:32.143
All right.
00:36:32.202 --> 00:36:33.483
So quick question.
00:36:33.543 --> 00:36:35.264
Rick Rader says he's
00:36:35.324 --> 00:36:37.527
building a Dumas boat and
00:36:37.606 --> 00:36:39.608
wants to fiberglass the hull.
00:36:39.648 --> 00:36:41.949
Will fiberglassing waterproof the hull?
00:36:42.510 --> 00:36:42.851
Yes.
00:36:43.170 --> 00:36:44.733
Fiberglass will waterproof the hull.
00:36:46.273 --> 00:36:46.494
Perfect.
00:36:46.514 --> 00:36:48.396
All right.
00:36:48.456 --> 00:36:48.715
Got it.
00:36:50.295 --> 00:36:50.496
All right,
00:36:50.576 --> 00:36:53.139
so now that I've done rough trimming,
00:36:53.478 --> 00:36:55.581
I need to do some
00:36:56.141 --> 00:36:58.505
additional sanding to shape
00:36:58.545 --> 00:37:01.407
this and get things flush.
00:37:05.911 --> 00:37:10.396
I'm using the coarse paper
00:37:10.516 --> 00:37:12.059
on my quicksand hand sander.
00:37:19.248 --> 00:37:21.952
Alright,
00:37:21.992 --> 00:37:25.356
so we've got some rough shaping here.
00:37:26.097 --> 00:37:27.018
We don't want to go all the
00:37:27.059 --> 00:37:29.282
way to where we need to go
00:37:29.322 --> 00:37:30.463
because at this point we
00:37:30.503 --> 00:37:32.106
need to rough up the surface.
00:37:33.429 --> 00:37:34.250
We need to rough up the
00:37:34.289 --> 00:37:35.931
surface because we're not
00:37:36.030 --> 00:37:38.411
done applying stuff just yet.
00:37:40.012 --> 00:37:44.034
When you go to apply the
00:37:44.134 --> 00:37:46.074
epoxy and the micro balloons,
00:37:46.753 --> 00:37:50.135
you're going to have most
00:37:50.175 --> 00:37:50.835
of the way there.
00:37:51.976 --> 00:37:52.876
But the rest of the way
00:37:52.916 --> 00:37:54.097
there is going to be taken
00:37:54.117 --> 00:37:55.976
care of by spackle.
00:37:56.858 --> 00:37:57.958
So I'm trying to rough up
00:37:57.978 --> 00:38:00.079
the surface where I know I
00:38:00.099 --> 00:38:01.179
need to apply spackle.
00:38:02.590 --> 00:38:03.329
They're still,
00:38:03.849 --> 00:38:06.530
given that I put the glass
00:38:06.570 --> 00:38:07.992
cloth on the backside here,
00:38:08.431 --> 00:38:09.411
there's still a ridge
00:38:09.472 --> 00:38:11.492
between this portion of the
00:38:11.532 --> 00:38:13.893
wing and this portion of the cover.
00:38:14.313 --> 00:38:15.313
So I need to fill that.
00:38:15.713 --> 00:38:17.253
I need to fill that with some spackle.
00:38:17.393 --> 00:38:18.393
Even though I did try to
00:38:18.434 --> 00:38:19.894
fill it with a little bit
00:38:19.914 --> 00:38:21.735
of the epoxy and micro balloons,
00:38:22.516 --> 00:38:23.356
it kind of dripped out
00:38:23.416 --> 00:38:24.775
because it was a little bit runny.
00:38:27.456 --> 00:38:28.717
A little rough up here.
00:38:28.757 --> 00:38:30.737
Put a little extra there.
00:38:32.485 --> 00:38:33.726
So now what I'm going to use
00:38:35.088 --> 00:38:39.951
is Auto Body Glazing and Spot Putty.
00:38:41.672 --> 00:38:43.293
This stuff dries pretty hard,
00:38:44.253 --> 00:38:45.253
sands pretty easy,
00:38:46.074 --> 00:38:50.157
and takes any further finish really,
00:38:50.177 --> 00:38:50.657
really well.
00:38:51.418 --> 00:38:52.097
And again,
00:38:52.137 --> 00:38:55.701
this is why I like to use a
00:38:55.740 --> 00:38:58.161
glove and why the finger is
00:38:58.242 --> 00:38:58.983
red already because I
00:38:59.003 --> 00:39:00.063
already did the other side.
00:39:00.423 --> 00:39:00.884
We'll get there.
00:39:01.771 --> 00:39:03.592
So I just squeeze a little
00:39:03.632 --> 00:39:06.695
bit out onto my finger and
00:39:06.795 --> 00:39:11.998
smoosh it where I need it.
00:39:12.018 --> 00:39:13.498
Knowing that I'm going to
00:39:13.739 --> 00:39:14.880
sand some of it back.
00:39:15.079 --> 00:39:16.420
I make sure that there's extra,
00:39:22.764 --> 00:39:23.264
but that's it.
00:39:26.467 --> 00:39:27.427
And then this is where you
00:39:27.447 --> 00:39:29.789
go away for several hours.
00:39:31.465 --> 00:39:32.465
and just let it dry.
00:39:33.586 --> 00:39:34.027
Let it dry.
00:39:34.088 --> 00:39:35.289
Don't try to force this
00:39:35.329 --> 00:39:38.132
stuff to dry too quickly
00:39:38.172 --> 00:39:38.873
because it won't.
00:39:39.012 --> 00:39:40.715
It's going to dry when it's going to dry.
00:39:41.335 --> 00:39:42.456
And I usually don't even
00:39:42.496 --> 00:39:45.780
think about it for at least four hours.
00:39:45.800 --> 00:39:46.061
All right,
00:39:46.101 --> 00:39:51.867
so this side has been drying for
00:39:55.668 --> 00:39:57.068
almost nine hours,
00:39:57.327 --> 00:39:59.329
nine and a half hours at this point.
00:39:59.648 --> 00:40:01.688
All right, so it's ready to go.
00:40:02.429 --> 00:40:04.630
So what we can do now is
00:40:04.650 --> 00:40:08.391
take our hand sander and
00:40:08.451 --> 00:40:10.391
start knocking away some of
00:40:10.431 --> 00:40:16.434
the bulk that we have.
00:40:27.907 --> 00:40:31.632
And then even still, when we get there,
00:40:32.635 --> 00:40:33.737
we can realize, oh,
00:40:33.757 --> 00:40:36.882
well that's nice and smooth already.
00:40:38.702 --> 00:40:41.184
we can start going with something else.
00:40:41.224 --> 00:40:43.405
I don't need to be quite as aggressive.
00:40:43.784 --> 00:40:44.945
And that's where one of
00:40:44.985 --> 00:40:45.985
these comes into play.
00:40:46.125 --> 00:40:47.606
I highly recommend one of these,
00:40:47.626 --> 00:40:49.547
a mouse sander of some kind.
00:40:49.987 --> 00:40:51.507
They make corded ones as
00:40:51.547 --> 00:40:53.027
well as this cordless version.
00:40:53.907 --> 00:40:55.007
I have the cordless version
00:40:55.208 --> 00:40:56.289
only because I had the
00:40:56.309 --> 00:40:58.228
batteries already for my lawn equipment.
00:40:59.929 --> 00:41:00.750
So yeah,
00:41:01.811 --> 00:41:04.572
I'm using a hundred and twenty
00:41:04.952 --> 00:41:05.512
grit paper.
00:41:06.751 --> 00:41:08.351
And I am going to just start
00:41:08.413 --> 00:41:10.793
taking back some of this red stuff.
00:41:11.913 --> 00:41:14.414
It will move from being red
00:41:14.574 --> 00:41:16.074
to pink when you sand it.
00:41:33.996 --> 00:41:34.056
so
00:42:14.112 --> 00:42:15.333
all right so now that I've
00:42:15.494 --> 00:42:16.914
done more knocking away the
00:42:16.934 --> 00:42:20.195
vast majority of the bad
00:42:20.235 --> 00:42:24.679
stuff I move in to use a
00:42:24.739 --> 00:42:26.920
sponge you can pick up
00:42:26.960 --> 00:42:29.061
these at walmart or any
00:42:29.101 --> 00:42:31.141
other sanding store so it's
00:42:31.181 --> 00:42:33.483
a sponge backed piece of
00:42:33.543 --> 00:42:35.423
sandpaper and I
00:42:35.483 --> 00:42:37.264
intentionally use a used
00:42:37.465 --> 00:42:39.106
one because it's less dull
00:42:41.125 --> 00:42:41.445
Yes,
00:42:41.565 --> 00:42:43.365
the the blue tape adjacent to the work
00:42:43.425 --> 00:42:44.865
area is to protect it that
00:42:44.925 --> 00:42:46.387
was very intentional I'm
00:42:46.407 --> 00:42:47.507
glad you observed that
00:42:48.106 --> 00:42:49.648
because I'm trying to focus
00:42:49.708 --> 00:42:51.088
on only the area that's
00:42:51.148 --> 00:42:53.929
within the blue lines That
00:42:53.969 --> 00:42:57.369
you can see right?
00:42:57.409 --> 00:42:58.969
So from here,
00:42:59.751 --> 00:43:00.851
it's more the same you're
00:43:00.871 --> 00:43:02.050
taking some of those more
00:43:02.170 --> 00:43:04.652
harsh sanding marks that
00:43:04.672 --> 00:43:07.532
you just made and you're
00:43:07.552 --> 00:43:08.552
going to knock them back
00:43:09.594 --> 00:43:10.773
and smooth things out and
00:43:13.559 --> 00:43:17.021
And you can see that up close,
00:43:20.184 --> 00:43:20.905
get it to focus.
00:43:20.945 --> 00:43:21.987
You can sort of see,
00:43:22.007 --> 00:43:23.628
even though it's a little bit unfocused,
00:43:23.648 --> 00:43:25.769
that right here there's a low spot.
00:43:26.351 --> 00:43:27.512
So I need to add a little
00:43:27.532 --> 00:43:29.693
bit more spackle right
00:43:29.733 --> 00:43:31.315
there and then come back
00:43:31.356 --> 00:43:32.215
and hit this again.
00:43:32.295 --> 00:43:32.956
So at this point,
00:43:33.036 --> 00:43:34.297
I'm going to set this aside.
00:43:34.699 --> 00:43:36.059
I don't want to work it anymore.
00:43:36.800 --> 00:43:38.101
because I know that I have
00:43:38.221 --> 00:43:39.981
more sanding to do and I
00:43:40.021 --> 00:43:43.143
don't want to over sand in other areas.
00:43:43.722 --> 00:43:45.802
So again, I still have my glove on.
00:43:46.023 --> 00:43:46.822
I'm ready to go.
00:43:48.523 --> 00:43:52.204
Put on just a little bit more,
00:43:53.364 --> 00:43:54.644
a little more up there too,
00:43:54.965 --> 00:43:56.025
a little low spot.
00:43:56.065 --> 00:44:02.927
All right.
00:44:02.967 --> 00:44:03.827
And then I've got my paper
00:44:03.867 --> 00:44:05.568
towel that I try to wipe off.
00:44:06.710 --> 00:44:11.114
the excess all right so
00:44:11.134 --> 00:44:14.436
that's really it um as as
00:44:14.476 --> 00:44:16.358
you can look into the
00:44:16.418 --> 00:44:17.981
corner you can see where
00:44:18.101 --> 00:44:20.463
I've done that fill and so
00:44:20.503 --> 00:44:21.463
everything is nice and
00:44:21.503 --> 00:44:23.346
smooth there there's a nice transition
00:44:24.356 --> 00:44:26.916
And that is essentially ready for primer.
00:44:27.378 --> 00:44:28.818
I'll do some final sanding
00:44:28.858 --> 00:44:30.039
and smoothing and check it
00:44:30.079 --> 00:44:31.400
all out and rotate everything.
00:44:31.960 --> 00:44:34.701
I like to actually look and
00:44:34.740 --> 00:44:37.262
inspect these in different lights.
00:44:37.782 --> 00:44:39.003
And what I mean by lights is
00:44:39.043 --> 00:44:40.583
like light orientation.
00:44:41.164 --> 00:44:42.465
So the way that light is
00:44:42.525 --> 00:44:44.606
coming down right now,
00:44:44.726 --> 00:44:45.887
I also have two spotlights
00:44:45.907 --> 00:44:46.567
coming this way.
00:44:47.135 --> 00:44:48.436
So it's kind of hard to tell
00:44:48.496 --> 00:44:49.657
in some of these transitions,
00:44:49.717 --> 00:44:51.018
but like little lips and
00:44:51.117 --> 00:44:53.219
edges will cast a slight shadow.
00:44:53.759 --> 00:44:55.840
So move the part around so
00:44:55.880 --> 00:44:57.501
that you are checking for
00:44:57.960 --> 00:44:59.481
any imperfections in that way,
00:44:59.521 --> 00:45:00.601
because you'll find that in
00:45:00.661 --> 00:45:02.023
some directions, you'll say, Oh,
00:45:02.182 --> 00:45:04.023
look at all of those flaws.
00:45:04.423 --> 00:45:05.644
Look at all of that sanding
00:45:05.664 --> 00:45:06.284
that I need to do.
00:45:07.894 --> 00:45:09.356
That's why light is important.
00:45:10.277 --> 00:45:13.239
When I designed the lighting in this shop,
00:45:13.340 --> 00:45:15.041
I specifically designed it
00:45:15.922 --> 00:45:16.922
for that purpose.
00:45:17.003 --> 00:45:19.184
I didn't want permanent
00:45:19.224 --> 00:45:21.206
lights in the distance.
00:45:22.047 --> 00:45:24.108
So if you'll notice like my shop,
00:45:24.208 --> 00:45:25.670
I've got just little tiny
00:45:25.710 --> 00:45:26.831
lights here and there that
00:45:27.052 --> 00:45:28.172
illuminate things so that I
00:45:28.193 --> 00:45:29.072
don't trip and fall.
00:45:29.773 --> 00:45:31.456
I don't have a very well-lit
00:45:31.576 --> 00:45:32.536
entire basement.
00:45:32.556 --> 00:45:34.137
I have a well-lit shop.
00:45:35.110 --> 00:45:36.711
Because if I have light over
00:45:36.771 --> 00:45:39.652
there casting inward into the shop,
00:45:39.773 --> 00:45:41.273
I could miss something that
00:45:41.313 --> 00:45:43.253
I'm looking at from the
00:45:43.313 --> 00:45:44.594
light that is being cast
00:45:44.813 --> 00:45:47.135
down on top of me.
00:45:47.175 --> 00:45:48.596
So directionality of light
00:45:49.115 --> 00:45:53.597
does matter in that regard.
00:45:53.637 --> 00:45:54.458
So from there,
00:45:54.637 --> 00:45:57.478
once I have everything sanded smooth,
00:45:58.159 --> 00:46:01.139
I will take our deluxe materials.
00:46:02.349 --> 00:46:04.730
Fine, super lightweight glass fiber,
00:46:04.809 --> 00:46:05.309
laminated.
00:46:05.610 --> 00:46:06.251
This is .
00:46:06.291 --> 00:46:08.090
six ounces per square yard.
00:46:08.731 --> 00:46:11.253
Very lightweight fabric.
00:46:11.472 --> 00:46:16.914
And I will use the Easy Coat to apply this,
00:46:17.014 --> 00:46:19.135
and I will do a filler
00:46:19.615 --> 00:46:21.416
layer with the micro balloons.
00:46:21.996 --> 00:46:23.538
Because it'll be easy, it'll be quick,
00:46:24.117 --> 00:46:26.719
and then I can move on directly to prime.
00:46:28.092 --> 00:46:29.612
I want to prime this so that
00:46:29.634 --> 00:46:31.114
I have a nice chemical and
00:46:31.155 --> 00:46:34.858
mechanical bond before I apply paint.
00:46:35.518 --> 00:46:37.719
That way, that paint will not chip up,
00:46:38.121 --> 00:46:39.061
which is the whole reason
00:46:39.101 --> 00:46:40.842
we're doing this in the first place,
00:46:40.902 --> 00:46:41.204
really,
00:46:41.724 --> 00:46:42.965
because all the paint was chipping
00:46:43.045 --> 00:46:44.246
up and flaking off of the
00:46:44.286 --> 00:46:46.288
plastic on the top.
00:46:46.327 --> 00:46:46.807
Make sense?
00:46:47.768 --> 00:46:48.170
Yes, sir.
00:46:48.730 --> 00:46:50.110
All right.
00:46:50.190 --> 00:46:51.211
Any other questions since
00:46:51.251 --> 00:46:52.132
I've been yammering?
00:46:56.543 --> 00:47:00.065
I do not see any questions as of yet.
00:47:00.146 --> 00:47:00.405
Okay.
00:47:05.228 --> 00:47:07.889
Another thing that you can
00:47:08.050 --> 00:47:10.271
use this technique for is repairs.
00:47:12.172 --> 00:47:13.231
Sometimes you'll have a
00:47:13.271 --> 00:47:14.893
model that has fiberglass parts,
00:47:14.952 --> 00:47:17.173
like a cowl, for example.
00:47:17.934 --> 00:47:20.195
You can repair those cracks pretty easily,
00:47:20.255 --> 00:47:22.416
but it's important to know how to do it.
00:47:23.655 --> 00:47:26.159
Really what it involves is a
00:47:26.179 --> 00:47:29.322
lot of patience and frankly more work.
00:47:30.543 --> 00:47:32.585
When you have a cowl that cracks,
00:47:32.826 --> 00:47:34.788
it's really important to
00:47:34.847 --> 00:47:37.851
know that the way this stuff behaves,
00:47:37.951 --> 00:47:41.594
you can't just simply put
00:47:41.635 --> 00:47:42.916
glue on the crack that you see.
00:47:43.972 --> 00:47:45.432
um what you have to do is
00:47:45.532 --> 00:47:47.773
you have to sand back all
00:47:47.813 --> 00:47:48.833
the paint so that you can
00:47:48.893 --> 00:47:50.614
see the fiberglass and see
00:47:50.755 --> 00:47:52.934
where the crack goes once
00:47:52.954 --> 00:47:54.135
you find where the crack
00:47:54.476 --> 00:47:56.516
ends you need to drill that
00:47:56.617 --> 00:47:58.896
out with a hole a round
00:47:58.978 --> 00:48:02.639
clean sharp hole then you
00:48:02.679 --> 00:48:05.460
can do a backing with more
00:48:05.500 --> 00:48:07.139
fiberglass to seal the hole
00:48:07.521 --> 00:48:08.721
fill the hole with more of
00:48:08.780 --> 00:48:11.262
the the red spackle or even you know the
00:48:11.701 --> 00:48:13.101
The micro balloons in epoxy,
00:48:13.141 --> 00:48:13.822
that'll work too.
00:48:14.543 --> 00:48:15.422
Sand it smooth.
00:48:16.284 --> 00:48:19.166
And ideally you want to try
00:48:19.226 --> 00:48:23.489
to flow more epoxy into that crack.
00:48:24.188 --> 00:48:26.170
However, that's really difficult to do.
00:48:26.210 --> 00:48:28.311
It's generally not thin enough to do that.
00:48:29.632 --> 00:48:30.713
A lot of people will just
00:48:30.733 --> 00:48:32.235
simply cut the crack and
00:48:32.255 --> 00:48:32.994
then they'll mend it.
00:48:34.315 --> 00:48:35.036
But in our case,
00:48:35.456 --> 00:48:36.336
we're dealing with such
00:48:36.376 --> 00:48:37.637
tight tolerances on a lot
00:48:37.657 --> 00:48:38.878
of these scale things that
00:48:40.034 --> 00:48:44.617
Usually what is done is thin CA.
00:48:45.637 --> 00:48:48.579
Hold the part together, thin CA,
00:48:48.619 --> 00:48:50.380
let it run down in through
00:48:50.400 --> 00:48:51.721
the crack and the fibers
00:48:52.402 --> 00:48:53.382
and let it cure out.
00:48:53.983 --> 00:48:55.043
And then from there,
00:48:55.224 --> 00:48:58.826
it's strong enough for more epoxy.
00:49:00.045 --> 00:49:00.806
You'll take like a
00:49:00.867 --> 00:49:03.447
lightweight cloth and apply
00:49:03.487 --> 00:49:06.349
some fiberglass epoxy and fiberglass,
00:49:06.409 --> 00:49:06.570
etc.
00:49:06.690 --> 00:49:07.550
on the inside.
00:49:08.288 --> 00:49:09.789
And that way on the outside
00:49:09.829 --> 00:49:11.168
you can use more spackle
00:49:11.489 --> 00:49:14.070
and get the crack nice and
00:49:14.110 --> 00:49:15.731
smooth on the outside.
00:49:16.731 --> 00:49:17.791
That way you have a nice finish.
00:49:17.871 --> 00:49:21.552
Repaint, reapply rivets or other details,
00:49:22.793 --> 00:49:24.474
and then move on from there.
00:49:24.753 --> 00:49:26.155
So it's a lot of work.
00:49:26.175 --> 00:49:27.454
It can be done.
00:49:27.554 --> 00:49:28.436
I've done it myself.
00:49:29.956 --> 00:49:34.940
It's not fun, but it can be done.
00:49:35.639 --> 00:49:36.541
And that's part of the
00:49:36.581 --> 00:49:38.222
reason why when you go to a
00:49:38.282 --> 00:49:40.842
shop and you have car
00:49:40.882 --> 00:49:43.784
repairs for fiberglass,
00:49:44.405 --> 00:49:46.567
that's why it's so expensive.
00:49:46.927 --> 00:49:47.646
You're not paying
00:49:47.686 --> 00:49:49.527
necessarily for the fiberglass and epoxy.
00:49:49.547 --> 00:49:50.648
You're paying for the labor
00:49:50.909 --> 00:49:52.949
and skilled labor at that
00:49:52.989 --> 00:49:54.030
to do all of this stuff.
00:49:55.492 --> 00:49:57.652
So I'll just say that we
00:49:57.672 --> 00:49:59.273
have really skilled tradesmen
00:50:00.836 --> 00:50:01.516
in this area.
00:50:01.677 --> 00:50:03.157
And you can go down a deep,
00:50:03.197 --> 00:50:04.657
dark rabbit hole with just
00:50:04.677 --> 00:50:05.777
fiberglass and epoxy.
00:50:05.858 --> 00:50:07.318
But what I'm giving you is
00:50:07.378 --> 00:50:08.719
just enough of the basics
00:50:08.778 --> 00:50:11.699
to use this as a tool to
00:50:11.739 --> 00:50:13.059
not get yourself in trouble
00:50:13.280 --> 00:50:14.199
or other people.
00:50:15.880 --> 00:50:17.760
But you have enough to make
00:50:17.780 --> 00:50:19.420
good use of it and start
00:50:19.481 --> 00:50:22.822
playing with it and not be afraid of it.
00:50:22.862 --> 00:50:23.561
So like I said,
00:50:23.581 --> 00:50:25.302
just two layers of the
00:50:25.342 --> 00:50:27.342
fiberglass cloth around this.
00:50:29.365 --> 00:50:31.628
just in summary two layers
00:50:31.668 --> 00:50:32.789
of fiberglass went around
00:50:32.809 --> 00:50:35.150
the back side and then I
00:50:35.371 --> 00:50:37.793
applied remaining epoxy
00:50:37.833 --> 00:50:38.672
mixed with the micro
00:50:38.713 --> 00:50:42.255
balloons into this area as
00:50:42.295 --> 00:50:43.856
well as try to create this
00:50:43.916 --> 00:50:45.117
transition this little
00:50:45.157 --> 00:50:47.639
fillet and from there let
00:50:47.659 --> 00:50:49.161
that cure out I cut off the
00:50:49.362 --> 00:50:52.483
excess and then I applied
00:50:52.563 --> 00:50:54.244
some of my spackling putty
00:50:54.344 --> 00:50:55.405
over here on my spackling
00:50:55.445 --> 00:50:56.527
putty once it was cured I
00:50:56.567 --> 00:50:57.588
sanded everything back
00:50:58.177 --> 00:50:59.797
Found additional work that need to do.
00:51:00.057 --> 00:51:01.018
So this is iterative.
00:51:01.358 --> 00:51:02.599
It didn't take me very long.
00:51:03.681 --> 00:51:04.840
It's just you have to do it
00:51:05.221 --> 00:51:06.541
and then allow it to dry
00:51:06.722 --> 00:51:07.402
and give it time.
00:51:07.623 --> 00:51:08.884
So there's a time investment,
00:51:08.963 --> 00:51:09.884
but you have to think
00:51:10.385 --> 00:51:11.485
almost a couple of steps
00:51:11.525 --> 00:51:14.606
ahead to know what you're getting into.
00:51:14.666 --> 00:51:15.047
All right.
00:51:15.708 --> 00:51:16.648
Any other questions?
00:51:17.929 --> 00:51:18.190
Yeah.
00:51:19.489 --> 00:51:20.751
Suter family asked,
00:51:20.811 --> 00:51:22.331
is it OK if I share a
00:51:22.371 --> 00:51:24.873
couple of watch outs regarding epoxy?
00:51:25.675 --> 00:51:26.175
Oh, sure.
00:51:26.614 --> 00:51:26.876
Sure.
00:51:26.936 --> 00:51:27.215
Yeah.
00:51:27.295 --> 00:51:27.536
I mean,
00:51:27.896 --> 00:51:31.597
epoxy inherently can be pretty
00:51:31.637 --> 00:51:32.498
dangerous chemicals.
00:51:33.177 --> 00:51:33.958
I know that there are some
00:51:34.018 --> 00:51:35.378
people that can be pretty sensitive.
00:51:35.398 --> 00:51:36.759
I'm just going to yammer on
00:51:36.818 --> 00:51:37.659
some of the safety stuff
00:51:37.679 --> 00:51:39.500
that I have while Suter Family is typing.
00:51:41.601 --> 00:51:42.561
Some people can be pretty
00:51:42.621 --> 00:51:43.802
sensitive to epoxy.
00:51:45.181 --> 00:51:46.583
Some people can even develop
00:51:47.599 --> 00:51:51.387
They make masks that you can use,
00:51:52.130 --> 00:51:53.072
essentially ventilator
00:51:53.112 --> 00:51:54.474
masks that can neutralize that.
00:51:54.514 --> 00:51:55.597
They have carbon filters or
00:51:55.637 --> 00:51:56.760
diatomaceous earth.
00:51:57.740 --> 00:51:58.442
So there are things like
00:51:58.481 --> 00:51:59.822
that to help eliminate some
00:51:59.862 --> 00:52:02.184
of those fumes if you're close to that.
00:52:02.563 --> 00:52:03.684
Don't get it in your eyes.
00:52:04.184 --> 00:52:05.065
If it's in your eyes,
00:52:05.206 --> 00:52:06.967
flush it out ASAP because
00:52:08.027 --> 00:52:09.188
the heat from your body
00:52:09.228 --> 00:52:11.190
temperature will help it cure faster.
00:52:12.590 --> 00:52:13.610
It can cause damage.
00:52:14.032 --> 00:52:15.793
It is a chemical after all.
00:52:16.773 --> 00:52:17.974
If it gets on your fingers,
00:52:19.034 --> 00:52:20.675
isopropyl alcohol immediately.
00:52:21.496 --> 00:52:23.018
use that to remove that from
00:52:23.057 --> 00:52:24.739
your fingers it's not
00:52:24.778 --> 00:52:25.840
necessarily going to burn
00:52:25.900 --> 00:52:27.661
or tingle but it's not good
00:52:27.701 --> 00:52:31.282
for you all right and then
00:52:31.342 --> 00:52:34.704
in addition to that the
00:52:34.764 --> 00:52:36.806
dust when you sand this
00:52:36.847 --> 00:52:38.447
stuff since I'm not doing a
00:52:38.608 --> 00:52:39.869
whole lot of work here
00:52:39.889 --> 00:52:40.949
tonight I did not use a
00:52:41.009 --> 00:52:43.650
respirator but I do have one
00:52:45.682 --> 00:52:46.143
Right here,
00:52:46.242 --> 00:52:49.003
I have a basic cloth mask that
00:52:49.123 --> 00:52:51.605
I use when I'm doing some of this stuff.
00:52:51.704 --> 00:52:52.625
In addition to that,
00:52:52.764 --> 00:52:54.826
I have my full respirator
00:52:55.826 --> 00:52:57.326
out down with my painting stuff.
00:52:57.346 --> 00:52:58.567
That's where I last used it.
00:52:59.226 --> 00:52:59.567
It's got an
00:52:59.586 --> 00:53:08.329
N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N-N
00:53:13.175 --> 00:53:14.476
It still fits relatively well,
00:53:14.496 --> 00:53:15.737
at least well enough for paint,
00:53:16.139 --> 00:53:17.581
and I had leftover filters.
00:53:17.940 --> 00:53:19.443
So yeah,
00:53:19.802 --> 00:53:23.146
some good PPE will go a long way
00:53:23.588 --> 00:53:25.550
if you use this pretty frequently.
00:53:26.231 --> 00:53:27.672
All right, Souter family, what you got?
00:53:30.786 --> 00:53:32.909
uh, he said the more epoxy you mix,
00:53:32.969 --> 00:53:34.608
the faster it will cure.
00:53:34.929 --> 00:53:36.789
So only makes a little more
00:53:36.829 --> 00:53:37.831
than you think you'll
00:53:38.070 --> 00:53:39.771
reasonably be able to work
00:53:39.811 --> 00:53:40.791
with at one time.
00:53:40.931 --> 00:53:44.034
Secondly, if you're going to thin,
00:53:44.094 --> 00:53:44.793
be sure.
00:53:44.914 --> 00:53:45.954
And he's typing.
00:53:46.454 --> 00:53:47.755
And I wanted to point out to
00:53:48.735 --> 00:53:52.898
make sure you read the mix ratio.
00:53:52.978 --> 00:53:54.978
If you don't have those mix ratios,
00:53:55.039 --> 00:53:55.699
correct.
00:53:56.480 --> 00:53:56.719
Um,
00:53:58.001 --> 00:53:59.262
You're going to have some issues.
00:54:00.161 --> 00:54:01.682
He said, so if you're going too thin,
00:54:01.742 --> 00:54:03.143
be sure you use only
00:54:03.224 --> 00:54:06.744
denatured ethanol and only
00:54:06.905 --> 00:54:08.907
at a max of about five percent.
00:54:09.246 --> 00:54:09.786
Yeah.
00:54:09.867 --> 00:54:11.708
So don't be using isopropyl
00:54:11.807 --> 00:54:14.048
alcohol because what's the
00:54:14.128 --> 00:54:16.150
other ingredient in isopropyl alcohol?
00:54:17.451 --> 00:54:19.811
Water.
00:54:19.851 --> 00:54:22.233
You don't want water in your epoxy mix.
00:54:22.833 --> 00:54:23.634
Water and oil.
00:54:24.420 --> 00:54:24.940
Exactly.
00:54:25.081 --> 00:54:26.302
It's not going to cure out.
00:54:26.601 --> 00:54:28.063
It's going to do really bad things.
00:54:28.923 --> 00:54:29.103
Yeah,
00:54:29.224 --> 00:54:31.864
and adding too much will kill the cure.
00:54:33.106 --> 00:54:34.867
So you're messing with
00:54:36.367 --> 00:54:39.969
chemical ratios of a reaction.
00:54:40.449 --> 00:54:41.530
And if you dilute that
00:54:41.570 --> 00:54:43.152
reaction out too much,
00:54:44.472 --> 00:54:45.432
the reaction won't happen.
00:54:46.273 --> 00:54:47.393
So thank you for that gotcha.
00:54:48.547 --> 00:54:50.210
George is asking,
00:54:50.510 --> 00:54:51.931
when using three-quarter
00:54:52.090 --> 00:54:54.193
ounce cloth in Z-Poxy
00:54:54.474 --> 00:54:57.036
finishing resin to cover a sheeted plane,
00:54:57.076 --> 00:54:58.496
do you recommend thinning
00:54:58.536 --> 00:55:00.639
the Z-Poxy resin with alcohol?
00:55:01.199 --> 00:55:04.943
If you're using finishing resin, no.
00:55:05.003 --> 00:55:06.184
Finishing resin is
00:55:06.623 --> 00:55:08.146
definitely thin enough to
00:55:08.166 --> 00:55:09.447
get into three-quarter ounce.
00:55:11.420 --> 00:55:13.862
if you feel like you aren't
00:55:14.041 --> 00:55:15.163
getting in there what you
00:55:15.202 --> 00:55:16.224
really need to do is start
00:55:16.304 --> 00:55:17.965
working the epoxy into it
00:55:18.005 --> 00:55:20.405
so use like an old credit
00:55:20.447 --> 00:55:22.168
card I've seen people use I
00:55:22.228 --> 00:55:23.829
personally prefer to use
00:55:25.050 --> 00:55:28.492
cardstock again paper it's
00:55:28.512 --> 00:55:29.672
biodegradable toss in the
00:55:29.693 --> 00:55:31.114
garbage feel a little bit
00:55:31.514 --> 00:55:32.614
less bad about myself
00:55:32.655 --> 00:55:33.795
rather than using plastic
00:55:33.856 --> 00:55:36.418
right and it's cheap it's
00:55:36.538 --> 00:55:38.338
easily come by and I use
00:55:38.478 --> 00:55:39.860
cardstock a lot for tracing
00:55:39.900 --> 00:55:40.721
a lot of different things
00:55:42.025 --> 00:55:43.905
I've used fiberglass really
00:55:44.085 --> 00:55:47.387
easy and cardstock for
00:55:47.467 --> 00:55:49.009
creating Bombay doors.
00:55:49.268 --> 00:55:50.449
Go to my YouTube channel.
00:55:50.869 --> 00:55:51.710
I've got a really great
00:55:52.291 --> 00:55:53.670
coverage of when I did the
00:55:53.710 --> 00:55:55.472
Saab B-seventeen Bombay doors.
00:55:55.492 --> 00:55:57.672
It started life as just a
00:55:57.753 --> 00:56:00.755
tracing on the bottom of a built fuselage,
00:56:01.335 --> 00:56:03.436
laid out the glass over top of it,
00:56:03.657 --> 00:56:06.398
and then literally traced over top.
00:56:06.737 --> 00:56:08.199
And it just started with cardstock.
00:56:10.394 --> 00:56:14.135
So yeah, it can be a really useful tool.
00:56:15.177 --> 00:56:16.657
Moving on, next question.
00:56:16.956 --> 00:56:18.717
Can epoxy resin and
00:56:18.777 --> 00:56:20.878
fiberglass be used on a foam wing?
00:56:21.057 --> 00:56:22.958
Absolutely, absolutely.
00:56:23.918 --> 00:56:26.739
The vast majority of large
00:56:26.840 --> 00:56:28.800
model airplanes are foam
00:56:28.840 --> 00:56:32.362
core with a balsa skin or
00:56:33.601 --> 00:56:35.603
combination of balsa and fiberglass.
00:56:37.358 --> 00:56:39.860
So the fiberglass itself, again,
00:56:39.880 --> 00:56:40.822
you have to be careful
00:56:40.862 --> 00:56:42.322
because if you get into
00:56:42.623 --> 00:56:44.125
those exothermic reactions,
00:56:44.164 --> 00:56:45.266
it can melt the foam.
00:56:46.567 --> 00:56:47.827
So that's why I say use epoxy.
00:56:49.494 --> 00:56:51.056
um in addition to that you
00:56:51.096 --> 00:56:52.155
have to also be careful
00:56:52.215 --> 00:56:55.077
with uh laminating epoxy or
00:56:55.197 --> 00:56:56.858
sorry fiberglass onto foam
00:56:57.418 --> 00:56:59.318
because if there's some
00:56:59.358 --> 00:57:00.798
sort of chemical reaction
00:57:01.119 --> 00:57:02.940
that happens later or too
00:57:02.980 --> 00:57:04.739
much heat from the sun that
00:57:04.780 --> 00:57:06.041
happens later you'll
00:57:06.061 --> 00:57:07.460
develop soft spots and
00:57:07.521 --> 00:57:08.422
bubbles under the
00:57:08.461 --> 00:57:09.981
fiberglass so that's why a
00:57:10.001 --> 00:57:12.123
lot of people try to take the the foam
00:57:13.103 --> 00:57:14.144
skin it with like
00:57:14.264 --> 00:57:16.447
one-sixteenth-inch balsa wood,
00:57:16.827 --> 00:57:18.289
and then fiberglass it
00:57:18.309 --> 00:57:19.969
because you get less of
00:57:20.030 --> 00:57:22.851
that gassing effect because
00:57:22.871 --> 00:57:24.193
of the chemical differential.
00:57:25.114 --> 00:57:25.914
I've seen it happen.
00:57:26.536 --> 00:57:27.496
My poor buddy Carl.
00:57:28.938 --> 00:57:30.099
You're P-forty, my brother.
00:57:31.980 --> 00:57:33.101
Unfortunate, but we love it.
00:57:35.389 --> 00:57:37.291
So Mitch asked,
00:57:37.510 --> 00:57:38.751
is it better to mix by
00:57:38.891 --> 00:57:40.291
weight than volume?
00:57:40.931 --> 00:57:42.751
Ryan Elliott also chimed in
00:57:42.791 --> 00:57:46.313
and says he mixes ratio in
00:57:46.353 --> 00:57:47.853
a digital gram scale.
00:57:47.994 --> 00:57:49.914
Great way to accurately mix.
00:57:50.393 --> 00:57:52.094
Yeah, kitchen scale.
00:57:52.235 --> 00:57:53.054
Have one in your shop.
00:57:53.635 --> 00:57:54.434
This is an old one.
00:57:54.474 --> 00:57:55.356
I bought my wife a nice
00:57:55.396 --> 00:57:56.315
pretty new one so that I
00:57:56.335 --> 00:57:57.096
could have the old one.
00:57:57.976 --> 00:57:59.797
Definitely use grams.
00:58:00.797 --> 00:58:01.818
The reason that you use
00:58:01.858 --> 00:58:03.360
grams is because you have
00:58:03.481 --> 00:58:05.561
far more resolution.
00:58:06.242 --> 00:58:07.844
You go to mix up even an
00:58:08.143 --> 00:58:13.108
eighth ounce of epoxy, that's a lot.
00:58:13.528 --> 00:58:15.570
It's a lot of epoxy.
00:58:16.311 --> 00:58:17.391
So for context,
00:58:17.452 --> 00:58:18.492
what I mixed up here for
00:58:18.572 --> 00:58:20.414
each one of these was two grams.
00:58:21.074 --> 00:58:23.197
One gram of epoxy, one gram of hardener.
00:58:24.197 --> 00:58:24.597
That's it.
00:58:27.255 --> 00:58:27.434
Now,
00:58:27.514 --> 00:58:29.635
it's also important to check the
00:58:29.735 --> 00:58:31.155
system that you're working with.
00:58:31.715 --> 00:58:33.556
I have fiberglass.
00:58:34.856 --> 00:58:36.978
It's a company or brand of
00:58:37.038 --> 00:58:38.978
fiberglass where it's a three to one.
00:58:39.918 --> 00:58:42.818
So you have to make sure
00:58:42.838 --> 00:58:43.878
that you check the ratio.
00:58:44.800 --> 00:58:47.519
But, yeah, do math.
00:58:47.539 --> 00:58:51.280
What was the other part of that question?
00:58:51.380 --> 00:58:52.202
Mitch had asked,
00:58:52.242 --> 00:58:53.262
is it better to mix by
00:58:53.342 --> 00:58:53.981
weight than volume?
00:58:54.289 --> 00:58:54.849
Yeah,
00:58:54.869 --> 00:58:56.829
that relates to what the manufacturer
00:58:56.869 --> 00:58:57.451
recommends.
00:58:57.610 --> 00:58:59.291
Most of the time it's going to be by mass,
00:58:59.612 --> 00:59:00.711
yeah.
00:59:00.733 --> 00:59:01.992
Brian Paris is asking,
00:59:02.012 --> 00:59:04.014
would you go over the epoxy
00:59:04.193 --> 00:59:05.755
micro balloon mix again
00:59:06.074 --> 00:59:08.456
using finishing resin ratio?
00:59:08.556 --> 00:59:10.657
I've heard of this but have not done it.
00:59:11.498 --> 00:59:12.498
Great show, thanks.
00:59:13.059 --> 00:59:16.221
So in my opinion, no.
00:59:17.327 --> 00:59:18.909
because I use primers.
00:59:20.869 --> 00:59:22.891
When you go over micro balloons,
00:59:22.931 --> 00:59:24.371
at least these micro balloons,
00:59:25.773 --> 00:59:26.572
I know they make micro
00:59:26.592 --> 00:59:28.815
balloons in different sizes, right?
00:59:29.235 --> 00:59:29.994
But on average,
00:59:30.054 --> 00:59:30.896
the micro balloons that
00:59:30.916 --> 00:59:31.655
you're going to get like
00:59:31.715 --> 00:59:33.516
from deluxe model products,
00:59:34.918 --> 00:59:36.418
when you go to sand it and
00:59:36.458 --> 00:59:42.181
then you apply a primer over top of it,
00:59:42.242 --> 00:59:43.543
the primer is going to fill
00:59:43.643 --> 00:59:45.103
in any small voids.
00:59:46.052 --> 00:59:47.373
And then once you go to do
00:59:47.434 --> 00:59:49.496
like your brush sanding.
00:59:49.675 --> 00:59:51.657
So like if I'm going to have
00:59:51.717 --> 00:59:53.760
something that's like baby but smooth,
00:59:54.280 --> 00:59:57.123
I will take effectively sand the primer.
00:59:57.222 --> 00:59:58.244
I don't actually sand it.
00:59:58.304 --> 00:59:59.565
I take a paper towel and I
00:59:59.646 --> 01:00:00.585
rub it down almost like
01:00:00.606 --> 01:00:02.688
it's a tack cloth because
01:00:02.728 --> 01:00:05.231
there's overspray from the primer.
01:00:06.211 --> 01:00:07.273
And that just helps sand
01:00:07.293 --> 01:00:08.634
back all of that overspray.
01:00:09.364 --> 01:00:10.724
And if you get to one of
01:00:10.764 --> 01:00:12.065
those sections where the
01:00:12.106 --> 01:00:13.467
micro balloons are not
01:00:13.567 --> 01:00:14.827
filled necessarily all the
01:00:14.847 --> 01:00:16.449
way with the primer,
01:00:16.668 --> 01:00:18.110
just add a little bit more primer.
01:00:18.809 --> 01:00:20.170
It's a lot easier to deal
01:00:20.190 --> 01:00:21.572
with it that way than it is
01:00:21.652 --> 01:00:24.693
with epoxy because you apply the epoxy,
01:00:24.733 --> 01:00:25.974
it's not going to be smooth
01:00:26.454 --> 01:00:28.416
or as smooth as what you've worked,
01:00:28.496 --> 01:00:28.777
right?
01:00:30.338 --> 01:00:31.358
You're not really adding any
01:00:31.438 --> 01:00:34.139
strength because the epoxy
01:00:34.159 --> 01:00:35.081
with the micro balloons
01:00:35.181 --> 01:00:36.882
inherently is not strong.
01:00:37.793 --> 01:00:38.813
Because you're effectively
01:00:38.893 --> 01:00:41.114
filling the epoxy with voids.
01:00:43.715 --> 01:00:45.277
So that's my best advice.
01:00:46.436 --> 01:00:48.617
I think you touched that answer,
01:00:48.677 --> 01:00:50.778
the used finishing resin.
01:00:50.938 --> 01:00:54.141
And he just chimed in again.
01:00:55.922 --> 01:00:57.822
I think he's asking, what is the...
01:00:59.530 --> 01:01:01.731
mixture of epoxy and micro
01:01:01.771 --> 01:01:03.251
balloons like how much of
01:01:03.371 --> 01:01:05.393
each and then he was asking
01:01:05.413 --> 01:01:06.873
would you use finishing
01:01:06.932 --> 01:01:08.054
resin over it so he's
01:01:08.134 --> 01:01:09.793
asking about ratio between
01:01:09.813 --> 01:01:12.375
yeah okay okay that that
01:01:12.534 --> 01:01:14.956
that that too um that's a
01:01:14.996 --> 01:01:18.396
tlar uh that's a that's a
01:01:18.416 --> 01:01:19.476
that looks about right
01:01:20.117 --> 01:01:23.297
that's that acronym tlar uh
01:01:23.398 --> 01:01:25.338
like I said I when I mix up
01:01:25.358 --> 01:01:27.199
micro balloons I go to the
01:01:27.239 --> 01:01:28.619
consistency of toothpaste
01:01:31.275 --> 01:01:32.677
So it's going to be kind of thick,
01:01:32.737 --> 01:01:34.418
but it's still going to kind of flow,
01:01:34.918 --> 01:01:35.197
right?
01:01:37.179 --> 01:01:38.840
And that's with finishing resin.
01:01:38.900 --> 01:01:39.860
Now, if I'm using like,
01:01:39.900 --> 01:01:41.942
thirty minute epoxy and micro balloons,
01:01:42.061 --> 01:01:42.902
that's going to have a
01:01:42.961 --> 01:01:44.103
totally different feel.
01:01:44.682 --> 01:01:46.304
It's going to be kind of goopy.
01:01:48.465 --> 01:01:48.864
So really,
01:01:49.164 --> 01:01:50.385
it depends on the epoxy that
01:01:50.405 --> 01:01:51.206
you're working with.
01:01:52.407 --> 01:01:54.166
But with finishing epoxy,
01:01:54.288 --> 01:01:55.507
I'm definitely targeting
01:01:55.708 --> 01:01:57.088
toothpaste consistency.
01:01:58.246 --> 01:01:59.085
Because you're only working
01:01:59.106 --> 01:02:00.807
with a little bit at a time, right?
01:02:01.007 --> 01:02:02.949
So you can't necessarily do
01:02:02.989 --> 01:02:03.389
this by weight.
01:02:03.409 --> 01:02:05.190
Like, this weighs nothing.
01:02:05.210 --> 01:02:08.172
Like, you can't do this by weight.
01:02:09.875 --> 01:02:11.036
So, again, T-lar.
01:02:11.235 --> 01:02:13.918
And the more micro-balloons that you add,
01:02:14.097 --> 01:02:14.938
effectively,
01:02:15.800 --> 01:02:18.681
the easier it will be to sand later.
01:02:18.702 --> 01:02:19.121
Okay.
01:02:21.023 --> 01:02:21.784
Because, again,
01:02:22.105 --> 01:02:25.367
you're trading off epoxy for empty space,
01:02:25.686 --> 01:02:26.068
effectively.
01:02:26.088 --> 01:02:26.208
Gotcha.
01:02:27.090 --> 01:02:28.532
So can you put too many
01:02:28.572 --> 01:02:30.072
micro balloons in then?
01:02:30.172 --> 01:02:30.592
Oh, sure.
01:02:30.932 --> 01:02:31.132
Sure.
01:02:32.034 --> 01:02:32.994
You can go to the point
01:02:33.034 --> 01:02:37.097
where it's so dry that you can't use it.
01:02:38.677 --> 01:02:40.398
So when you're going to do
01:02:40.438 --> 01:02:42.400
it for the first time, add some.
01:02:42.579 --> 01:02:43.400
See how it feels.
01:02:43.481 --> 01:02:44.260
Keep adding.
01:02:44.360 --> 01:02:45.121
See how it feels.
01:02:45.181 --> 01:02:45.842
Keep adding.
01:02:45.922 --> 01:02:46.601
See how it feels.
01:02:46.922 --> 01:02:48.242
You'll get experience with it.
01:02:48.342 --> 01:02:49.724
And I still make mistakes.
01:02:49.744 --> 01:02:52.945
And I'm just like, oh, I added too much.
01:02:53.005 --> 01:02:54.067
It happens.
01:02:54.126 --> 01:02:54.586
It happens.
01:02:56.259 --> 01:02:56.639
Brian,
01:02:56.679 --> 01:02:58.820
if you need any more clarification
01:02:58.880 --> 01:02:59.260
on that,
01:02:59.639 --> 01:03:01.480
please drop any other questions
01:03:01.539 --> 01:03:01.780
in the chat.
01:03:01.840 --> 01:03:03.501
I'm sorry I misunderstood your question.
01:03:03.740 --> 01:03:06.981
No, I knew where you were going,
01:03:07.021 --> 01:03:07.661
but I was like,
01:03:07.882 --> 01:03:10.003
I think he wanted the first
01:03:10.043 --> 01:03:10.983
part of that first.
01:03:11.023 --> 01:03:13.744
So I think it made sense.
01:03:15.164 --> 01:03:16.543
Rick said,
01:03:16.684 --> 01:03:18.724
Sig used to have a finishing
01:03:18.804 --> 01:03:20.565
resin epoxy that used only
01:03:20.606 --> 01:03:22.005
a few drops of hardener.
01:03:22.545 --> 01:03:24.025
Does anyone have a product
01:03:24.045 --> 01:03:26.467
like this that you're aware of?
01:03:26.786 --> 01:03:27.806
That's going to be more
01:03:27.847 --> 01:03:29.768
along the lines of a polyester resin.
01:03:30.527 --> 01:03:34.248
So the hardener is more of a catalyst.
01:03:36.289 --> 01:03:37.989
So it's going to be like a
01:03:38.090 --> 01:03:38.989
liquid in a tube.
01:03:39.210 --> 01:03:40.891
So like, for example, Bondo.
01:03:42.855 --> 01:03:45.476
Bondo has a brand of their
01:03:45.655 --> 01:03:46.936
their epoxy that you can
01:03:46.956 --> 01:03:49.018
get I know at Home Depot, I've seen it,
01:03:49.038 --> 01:03:50.179
that's where I got this.
01:03:51.559 --> 01:03:53.300
And their hardener for it is
01:03:53.340 --> 01:03:54.621
just like you get like a
01:03:54.701 --> 01:03:56.221
half gallon tub of it.
01:03:56.621 --> 01:03:57.621
And the hardener is like
01:03:57.661 --> 01:03:59.463
this little tiny tube.
01:04:00.123 --> 01:04:03.445
And I just I'm telling you
01:04:03.485 --> 01:04:04.945
now don't just don't go to
01:04:05.025 --> 01:04:06.826
polyesters if you if you
01:04:07.065 --> 01:04:08.447
absolutely can avoid it just
01:04:11.713 --> 01:04:12.594
it's not a matter of
01:04:12.635 --> 01:04:14.255
preference it's a matter of
01:04:14.355 --> 01:04:18.336
workability it's just it's
01:04:18.536 --> 01:04:20.717
much more difficult like if
01:04:20.797 --> 01:04:23.277
you were doing molds if
01:04:23.297 --> 01:04:25.539
you're making molds of an
01:04:25.599 --> 01:04:29.420
entire fuselage sure go at
01:04:29.460 --> 01:04:30.481
it because that's going to
01:04:30.501 --> 01:04:32.842
be a much more robust and
01:04:32.922 --> 01:04:36.822
longer lasting fiberglass for making a
01:04:37.498 --> 01:04:38.398
a mold,
01:04:38.458 --> 01:04:41.320
like to cast a new product off of it.
01:04:42.242 --> 01:04:43.943
But if you're just making
01:04:43.983 --> 01:04:46.083
repairs or covering a wing or something,
01:04:47.105 --> 01:04:48.985
I would really stick to epoxy only.
01:04:50.907 --> 01:04:53.769
Makes sense.
01:04:53.809 --> 01:04:54.210
Perfect.
01:04:54.690 --> 01:04:54.831
Yeah,
01:04:54.871 --> 01:04:57.172
Brian said you had covered everything
01:04:57.251 --> 01:04:58.572
he was looking for.
01:05:00.355 --> 01:05:02.096
Okay.
01:05:02.155 --> 01:05:03.657
We could wrap this up with a question.
01:05:04.380 --> 01:05:05.240
Okay.
01:05:05.300 --> 01:05:05.920
All right.
01:05:05.981 --> 01:05:06.822
The hard question.
01:05:07.101 --> 01:05:08.001
The hard question.
01:05:08.041 --> 01:05:12.684
All right.
01:05:12.704 --> 01:05:14.445
This is a highly debated topic,
01:05:14.527 --> 01:05:17.748
but I was able to actually
01:05:17.809 --> 01:05:21.911
speak to an aircraft mechanic.
01:05:21.931 --> 01:05:22.010
Okay.
01:05:24.032 --> 01:05:25.574
According to investigations,
01:05:26.094 --> 01:05:27.875
what was really the cause
01:05:28.034 --> 01:05:30.277
of a series of stall spins
01:05:30.757 --> 01:05:32.378
when the Texan was debuted?
01:05:35.563 --> 01:05:36.963
So what was actually the
01:05:37.023 --> 01:05:40.806
cause of a series of stall
01:05:40.846 --> 01:05:42.907
spins when the Texan was debuted?
01:05:42.947 --> 01:05:44.148
So to back up a little bit,
01:05:44.168 --> 01:05:45.608
a lot of people believe
01:05:46.170 --> 01:05:48.010
that the Texan is a very
01:05:48.130 --> 01:05:49.472
misbehaved airplane.
01:05:50.693 --> 01:05:52.072
It's really not.
01:05:53.775 --> 01:05:55.675
The issue arose from when
01:05:55.695 --> 01:05:57.456
there were a series of accidents.
01:05:58.193 --> 01:06:02.856
where pilots thought that at low speeds,
01:06:03.016 --> 01:06:04.336
it would just completely
01:06:04.657 --> 01:06:05.958
stall out and it would spin
01:06:05.998 --> 01:06:06.538
into the ground.
01:06:07.259 --> 01:06:10.179
So this wasn't actually a problem.
01:06:10.239 --> 01:06:13.521
There was a problem with the airplane.
01:06:15.322 --> 01:06:19.405
So what was that problem?
01:06:19.465 --> 01:06:21.286
And I think we'll give a
01:06:21.365 --> 01:06:24.266
hardware kit away for this
01:06:24.387 --> 01:06:27.668
one since it's a hard one.
01:06:27.768 --> 01:06:27.969
Yeah.
01:06:29.454 --> 01:06:31.494
This one's not very well known.
01:06:31.534 --> 01:06:33.836
We usually hear the pilot accounts.
01:06:34.336 --> 01:06:35.717
We don't necessarily hear
01:06:35.757 --> 01:06:37.778
the mechanic accounts of
01:06:37.858 --> 01:06:39.699
what goes on with these airplanes.
01:06:40.701 --> 01:06:43.882
Brian Andrus said placement of the wings?
01:06:44.943 --> 01:06:45.304
No.
01:06:45.943 --> 01:06:50.246
Lack of, well... Laminar flow?
01:06:50.447 --> 01:06:51.327
Laminar flow.
01:06:51.347 --> 01:06:51.387
No.
01:06:52.027 --> 01:06:54.590
I mean, it is technically related to flow,
01:06:54.769 --> 01:06:55.050
but...
01:06:57.958 --> 01:07:04.400
It has more to do with flaps.
01:07:04.440 --> 01:07:07.340
Remember, on this model of airplane,
01:07:07.920 --> 01:07:09.461
there are three wing segments.
01:07:09.501 --> 01:07:10.442
There's the middle straight
01:07:10.481 --> 01:07:12.222
section and then the outer
01:07:12.262 --> 01:07:15.664
wing panels give you your dihedral.
01:07:15.704 --> 01:07:16.804
The flaps themselves,
01:07:16.824 --> 01:07:17.903
you have a center section
01:07:17.985 --> 01:07:19.144
and two outer sections.
01:07:23.820 --> 01:07:25.320
The roll bar obstructing the view?
01:07:25.481 --> 01:07:25.780
No.
01:07:26.802 --> 01:07:33.666
No, that was an inconvenience.
01:07:34.306 --> 01:07:35.768
Issue with the flaps.
01:07:36.228 --> 01:07:37.568
You're on the right track.
01:07:39.010 --> 01:07:41.431
Can you name what it is?
01:07:41.831 --> 01:07:47.534
You're the closest so far, Pete.
01:07:47.635 --> 01:07:49.255
I know, right?
01:07:49.335 --> 01:07:50.277
Boundary layer.
01:07:52.177 --> 01:07:52.496
No,
01:07:52.556 --> 01:07:54.938
it's not related to the boundary layer.
01:07:58.681 --> 01:08:00.463
You guys can thank Joshua.
01:08:00.503 --> 01:08:02.903
He comes up with the toughest questions.
01:08:03.885 --> 01:08:05.706
Blanked out airflow on the tail?
01:08:05.925 --> 01:08:06.407
No.
01:08:07.266 --> 01:08:10.949
The outer flaps acted like the ailerons.
01:08:11.909 --> 01:08:13.311
No, that's not it.
01:08:14.411 --> 01:08:15.572
Flaps too heavy?
01:08:16.533 --> 01:08:17.394
No.
01:08:19.034 --> 01:08:20.235
Alright, well, I think
01:08:22.221 --> 01:08:23.643
I think we'll give it to Pete.
01:08:24.023 --> 01:08:25.144
He's the closest.
01:08:26.184 --> 01:08:27.944
It's not wash out or wash in.
01:08:28.045 --> 01:08:30.606
So what what happens is that
01:08:30.726 --> 01:08:34.189
the the flaps are like location.
01:08:36.649 --> 01:08:40.051
No, it's so there's there's a torque bar,
01:08:40.372 --> 01:08:41.412
there's a torque bar that
01:08:41.512 --> 01:08:43.153
lowers and raises these flaps.
01:08:44.113 --> 01:08:45.494
And there are pins that
01:08:45.534 --> 01:08:47.496
connect the torque bar to the flaps.
01:08:48.555 --> 01:08:49.877
what would happen is the
01:08:49.896 --> 01:08:51.658
vibration and torque would
01:08:51.818 --> 01:08:53.838
actually let those pins
01:08:53.979 --> 01:08:57.159
come out and so you had a
01:08:57.220 --> 01:09:00.041
situation where you would
01:09:00.100 --> 01:09:03.743
have flap differential so
01:09:03.802 --> 01:09:05.804
you the connection was made
01:09:05.844 --> 01:09:07.265
so you had control of the
01:09:07.305 --> 01:09:09.666
flap of the flaps on the
01:09:09.706 --> 01:09:11.426
middle flap but you had
01:09:11.466 --> 01:09:13.188
these torque tubes that
01:09:13.287 --> 01:09:14.528
connected the middle flap
01:09:14.627 --> 01:09:15.788
to the outer flaps
01:09:16.632 --> 01:09:18.154
So you would have pins fail,
01:09:18.734 --> 01:09:19.956
and one flap would work,
01:09:19.996 --> 01:09:21.016
and the other flap wouldn't.
01:09:21.136 --> 01:09:22.978
You would have flap differential,
01:09:23.378 --> 01:09:24.800
and there was not enough
01:09:25.159 --> 01:09:27.101
aileron authority to
01:09:27.322 --> 01:09:31.485
overcome that differential.
01:09:31.525 --> 01:09:36.250
So from there, you would have, they issued,
01:09:36.409 --> 01:09:37.069
oh, what was it?
01:09:37.090 --> 01:09:38.411
I have notes on this.
01:09:38.490 --> 01:09:39.051
I have notes.
01:09:40.676 --> 01:09:44.158
A tech order was issued to
01:09:44.239 --> 01:09:45.619
place just a standard
01:09:45.680 --> 01:09:47.561
rubber hose over those
01:09:47.782 --> 01:09:50.463
joints to help reduce the
01:09:50.484 --> 01:09:52.005
vibration but also keep the
01:09:52.045 --> 01:09:52.905
pins in place.
01:09:53.626 --> 01:09:54.145
Interesting.
01:09:54.546 --> 01:10:00.331
And they never had an issue after that,
01:10:00.350 --> 01:10:00.511
ever.
01:10:00.530 --> 01:10:02.813
So, this airplane is very well behaved.
01:10:02.832 --> 01:10:03.733
If you've got a Texan,
01:10:03.792 --> 01:10:06.255
go get some garden hose, cut off a piece,
01:10:06.354 --> 01:10:07.456
slide it over there.
01:10:09.311 --> 01:10:10.032
That's interesting.
01:10:10.453 --> 01:10:11.212
I like that.
01:10:11.233 --> 01:10:11.712
That was good.
01:10:11.912 --> 01:10:12.472
Uh, Pete,
01:10:12.694 --> 01:10:16.295
shoot us an email orders at Dubro.com.
01:10:17.456 --> 01:10:17.876
Uh,
01:10:18.435 --> 01:10:20.917
let me know if you want a two fifty six
01:10:21.037 --> 01:10:22.917
four forty six thirty two
01:10:22.997 --> 01:10:24.538
two millimeter or three
01:10:24.578 --> 01:10:27.020
millimeter hardware accessory kit.
01:10:27.100 --> 01:10:28.039
We'll get that sent out to you.
01:10:28.060 --> 01:10:30.641
Awesome.
01:10:30.761 --> 01:10:31.002
Yeah.
01:10:32.521 --> 01:10:33.103
All right, my man.
01:10:33.622 --> 01:10:35.564
Uh, good show.
01:10:35.963 --> 01:10:38.185
Everybody liked the epoxy topic.
01:10:39.721 --> 01:10:40.322
Like I said,
01:10:40.362 --> 01:10:41.622
some people feel like it's a
01:10:42.302 --> 01:10:44.023
difficult to approach topic,
01:10:44.483 --> 01:10:45.623
but it's really not.
01:10:45.904 --> 01:10:47.243
You just kind of have to dig in,
01:10:47.543 --> 01:10:48.564
and there are some little
01:10:48.604 --> 01:10:49.845
things along the way that
01:10:50.885 --> 01:10:52.885
you really got to watch out for.
01:10:53.725 --> 01:10:54.506
It's kind of messy.
01:10:54.626 --> 01:10:57.426
Be ready to clean up and have fun.
01:10:58.067 --> 01:10:59.646
Yeah.
01:10:59.686 --> 01:11:01.207
Yeah, don't be intimidated.
01:11:01.266 --> 01:11:02.648
It's not as hard as it seems.
01:11:03.108 --> 01:11:03.368
No.
01:11:04.167 --> 01:11:05.809
The first one may be a little rough,
01:11:05.969 --> 01:11:07.189
but you'll get through it.
01:11:07.208 --> 01:11:07.349
Yeah.
01:11:09.319 --> 01:11:10.761
I mean,
01:11:10.881 --> 01:11:12.060
nobody's great the first time that
01:11:12.081 --> 01:11:13.081
they do stuff like this.
01:11:13.720 --> 01:11:18.662
Just be aware that anything
01:11:18.681 --> 01:11:21.922
that you do can be fixed.
01:11:22.023 --> 01:11:24.703
Yeah.
01:11:25.002 --> 01:11:26.743
A little elbow grease and a
01:11:26.804 --> 01:11:28.663
hand sander and you'll get through it.
01:11:29.083 --> 01:11:30.144
Exactly.
01:11:30.243 --> 01:11:32.284
Exactly.
01:11:32.324 --> 01:11:32.864
Good stuff.
01:11:35.890 --> 01:11:37.551
Got one comment.
01:11:37.572 --> 01:11:39.533
Switch comments.
01:11:41.935 --> 01:11:43.034
What's going on here?
01:11:43.095 --> 01:11:43.395
There we go.
01:11:43.416 --> 01:11:44.837
I don't know.
01:11:44.856 --> 01:11:45.596
Great show.
01:11:46.278 --> 01:11:47.018
Thumbs up.
01:11:47.717 --> 01:11:48.639
Another great show.
01:11:48.679 --> 01:11:49.319
Thanks, guys.
01:11:49.359 --> 01:11:51.320
Thanks, everybody, for tuning in.
01:11:52.320 --> 01:11:53.202
Next show.
01:11:53.221 --> 01:11:54.863
I'm not at the office.
01:11:54.882 --> 01:11:56.543
I don't have my marker board.
01:11:56.904 --> 01:11:57.505
Is it the time?
01:11:57.524 --> 01:11:57.784
Two weeks.
01:11:57.984 --> 01:11:58.185
Two weeks.
01:11:58.265 --> 01:11:58.784
Two weeks.
01:12:00.492 --> 01:12:03.916
two weeks from today so yes
01:12:04.176 --> 01:12:05.717
it is the tenth February
01:12:05.818 --> 01:12:07.979
tenth will be the next show
01:12:08.201 --> 01:12:10.243
and then February twenty
01:12:10.443 --> 01:12:12.966
fourth after that so if you
01:12:12.985 --> 01:12:13.907
guys aren't subscribed to
01:12:13.926 --> 01:12:15.188
the YouTube channel please
01:12:15.207 --> 01:12:17.150
do so that way you get notifications
01:12:17.871 --> 01:12:19.692
They go up on the Facebook page as well.
01:12:20.632 --> 01:12:22.514
You can subscribe to the newsletter.
01:12:23.014 --> 01:12:24.414
We send an email blast out
01:12:24.435 --> 01:12:25.515
the night of as well.
01:12:26.856 --> 01:12:27.817
So that way you guys can
01:12:27.856 --> 01:12:30.298
stay in the loop and catch the next show.
01:12:30.918 --> 01:12:32.079
Joshua, as always,
01:12:32.119 --> 01:12:32.720
thank you for your
01:12:32.760 --> 01:12:36.783
knowledge and your tough questions.
01:12:36.802 --> 01:12:37.422
You got it.
01:12:37.483 --> 01:12:38.524
I got one for next time.
01:12:38.583 --> 01:12:39.083
It'll be fun.
01:12:39.925 --> 01:12:40.324
Be ready.
01:12:40.484 --> 01:12:42.046
Have Google in the cube, boys.
01:12:43.025 --> 01:12:45.568
It's another mechanics question or yeah.
01:12:46.663 --> 01:12:46.963
Love it.
01:12:47.225 --> 01:12:47.524
Love it.
01:12:48.065 --> 01:12:49.346
We'll see you guys in two weeks.
01:12:49.606 --> 01:12:51.088
Thanks, everybody, for tuning in.
01:12:51.529 --> 01:12:53.872
And as always, have a good night.
01:12:54.733 --> 01:12:55.533
Enjoy the building.
01:12:56.033 --> 01:12:58.036
And hopefully you get some
01:12:58.076 --> 01:12:59.358
warm weather soon so you
01:12:59.377 --> 01:13:00.177
can get out and fly.
01:13:00.479 --> 01:13:03.462
Or if you got snow, Dubrow Snowskis.
01:13:03.721 --> 01:13:04.082
Just saying.
01:13:04.662 --> 01:13:05.583
Yeah, man.
01:13:05.623 --> 01:13:06.505
Have a good night, everybody.
01:13:06.845 --> 01:13:07.065
Take care.
