epoxy repairs
Boris, if you could, would you please send to the TeamGrumman-List when you ask
a question? There are a lot of people anxious to hear how it's going.
Enlarged holes are a problem. That is primarily why I suggest clamping
everything in place first. The problem with the clamps is they tend to move
anyway. I always start with the bottom holes first. Then, if one or more gets
elongated during the fitting process, it isn't visible.
To answer your question, we use Pro-Set 125/229 and 7725 cloth. Repair
techniques for fiberglass, in general, are pretty much the same. Relieve the
area adjacent to the holes and build up the area with glass and epoxy. When
cured, sand to the correct height.
All of the filler material in the cowling is micro-beads. Micro beads are
typically used in the corners where it's difficult to get the glass to conform
to the corner. For small repairs on the flat surfaces, you can use any light
weight filler. Spot putty any pin holes. I prime with 6 coats of K-36, thinned
20%. K-36 is a high build urethane primer. Block sand the first time with 120.
Prime again with one or 2 coats as needed. Block sand with 320.

Hi Gary,
the cowl fitting process is going very nicely, thank you. While fitting the
cowl, I had to make a couple of holes larger than they have to be. They probably
could be left as is, but a perfectionist in me would like to fill them up and
then back drill them correctly.
I wonder if you or David could give some instructions regarding epoxy (and gel
coat) repair, especially what materials to use.
May I use this epoxy left from my boat repairs? -
http://www.westsystem.com/ss/105-epoxy-resin/ . I don't have any filler though.
What would be the correct filler? : http://www.westsystem.com/ss/fillers.
Thank you,
-Boris

Boris:
EPOXY 105 ... NO... Too soft and no strength.
Get the GRAY stuff you see on the counter tops at automotive parts stores.
I'm not at home base so I do not have the name... I'll get back to you.

Count me as a satisfied Jaguar Cowl owner. Recently I've been letting a fr
iend build instrument hours and have been enjoying 130KTAS at 7.5-8.0gph wi
th CHTs even and well below 390degF. The top-end speed is great when I nee
d it (Let's say 140KTAS at 9.8-ish=2C CHT's 410-ish [EDM])=2C but with gas
prices around DC running $5.50/gal I'm way cheaper per wet hour than the lo
cal rental fleet and we finish more approaches per flight hour.
