Fiberglass vs. Fabric

Ok, everyone, I've started to experiment with fiberglass. I bought the
foam, the fabric,hardner and resin. I've mix the resin and hardener
with micro balloons and came up with something that resembles honey
dijon salad dressing. I've put it on the foam, layed down the fabric
and then had to mix more resin and hardener. Put that mix on top and
spread it around. Layed down another layer of fabric, mixed more
resin/hardener, spead it around and layed down dacron.
Now the big question, Does this sound correct? Can anyone tell me if
I missed a step? This so far is a test piece, but I know what I can use
it for. I am kinda suprised of how flexable the fiished product is.

Put a layer of glass on the other side of the foam, then come back and
tell us how flexible it is.

Warning: Make d8mn sure you have the thing jigged to it's finished
position before the opposite side glass sets.

This is by far the hardest lesson about freedom. It goes against
instinct, and morality, to just sit back and watch people make
mistakes. We want to help them, which means control them and their
decisions, but in doing so we actually hurt them (and ourselves)."

I made a couple of test panels on 1/4" Clark foam using one layer of
heavier glass and one layer of model airplane glass on each side. You
could lay a 6" x 18" panel across two bricks and stand on it with out
much deflection. I figured it was good enough for a fuel tank, it has
held up for twenty years.

Thanks, I did layer up the other side and was quite suprised of the
stiffness. So far every piece will be flat, then cut to size and
glassed together, so it seems to be working out. Unfortunatley it's
been just under 70 deg. around here and especially in my basement so I
bought some 2 inch foam and a small heater. I made a make/shift oven to
help cure the fiberglass. I happen to have a remote thermometer inside
to watch the temp. It's been working out great.

Do it again, Lou.
Hey, it's fun, right?

Slice off a few long 1x2's and glass each differently.

One layer of BID each side.
Two layers each side.
Three layers should do the trick.

Also try the same with UNI.
Like for building spar caps.
A single layer of BID on the long sides (the 2" sides)
and UNI on the top and bottom for capstrips...


Then try some deep compound curves!

There are a couple of articles on one-off cowling construction on my CD.

Hey Caveman,
I tried your link but got nothing. Removed what I was supposed to and
still nothing.
Got Link?

I noticed that one has to scroll down the page to find the
files to be downloaded.

But not until the second time I tried the link.


Well, it works for me...

Like Fred said, scroll down the page a bit...
