1278.1 | Heard of it done but haven't tried it yet. | ZENDIA::REITH | Jim Reith DTN 226-6102 - LTN2-1/F02 | Thu Dec 27 1990 14:38 | 11 |
| I have a friend who's used this on center sections. It turned out fine
but you still need to fill it in. On thing that he used was a VERY
light misting of F77 to tack the cloth into place so he could move the
wing around without twisting the cloth out of alignment. It does sound
neat and fast but be careful of those fumes (or use UFO)
Is the P-38 the RCM plans with the twin .15-.20s? I'm going to build
that this winter and I'm pretty sure they recommend that method in the
construction article.
What did your friend fill the cloth grain with afterwards?

| The P-38 I saw was at a fun fly two years ago. I did not know
the builder/flyer. He was from Pennsylvania and either worked
at or owned an auto body shop, which probably accounts for the
immaculate finish of the plane. It was scratch built and he
estimated that he had about 1000 hrs. invested in it. It was
powered by twin HP 60's and had a wingspan of around 90 inches
if I remember correctly. It was entirely constructed of wood
and covered with light fiberglass and Ca. I real strong performer!
Regards,
Jim

1278.3 | digital CA applicators | POBOX::KAPLOW | Set the WAYBACK machine for 1982 | Fri Dec 28 1990 11:58 | 11 |
| I've seen it done without the benefit of a baggie! For many years,
I've used fingers to apply CA. It takes some practice, a certain
amount of common sense to know what NOT to do (pick your nose,
etc.) along with a certain LACK of common sense to try it in the
first place. CA in large puddles does not set up, giving you a
chance to work it in and around. If you feel heat, drop everything
quick, or become one with it!
Actually, when sanding small parts, I will intentionally apply a
layer of thick CA to my thumb and finger, to prevent from sanding
thru the skin of the fingers holding the part.

1278.4 | Some CA Glassing Tips. | PEE47::COX | So Speedy, how do we get zeez brains? | Fri Jan 04 1991 08:09 | 17 |
| I've been using this technique sucessfully on center sections for
several years. I wouldn't think of doing it any other way! There are
two simple tricks of the trade:
1. A light misting coat of 3M 77 spray adhesive insures that the cloth
stays put. This apparently doesn't effect the curing or strength of
the bond. Make sure all wrinkles are worked out of the cloth ahead of
time. The 3M can be pulled and repositioned a few times.
2. Let gravity help you along! To avoid puddles, tilt the piece and
flow on the thin CA from the top down. The cloth soaks up what is
required , and the excess flows downward. Pretty neat!
This technique was the subject of an article in Scale R/C Modeler a
year or two ago. Any help here Al?

| Re: .-1, Scott,
Oh boy! I'm familiar with the technique but honestly don't recall an
article on it in SR/CM. I could dig it out if anyone could supply more
info on which issue it appeared in.

I think it was back in the August timeframe.

1278.7 | Cost? | CLOSUS::TAVARES | John--Stay Low, Keep Moving! | Fri Jan 04 1991 10:18 | 1 |
| Isn't it expensive to use CA versus epoxy?

1278.8 | YES AND NO..... | UPWARD::CASEYA | THE DESERT RAT (I-RC-AV8) 551-5572 | Fri Jan 04 1991 13:00 | 14 |
| Re: .6, Tom, August of what year?
Re: .7, John, Yes, I should think so, at least up front.
Polyester or epoxy resin isn't all that cheap either (though
considerably cheaper by volume tha CA) however, considering the time
saved and the fact that resins go bad, causing you to frequently lose
nearly a whole can of it, cost may balance out somewhat in the long
run.
