More Drywall Gussets

To All:

As promised, here on this Newsgroup about six weeks ago, I've posted a
snapshot
of a rib gusset made from fiberglas drywall tape and polyurethane glue.

The photo is in the Files archive of the Fly5kfiles Group on Yahoo, in the
Practice Wing folder.


How about putting them somewhere else too? I don't do yahoo groups, for the
fear of even more spam, which I have heard that Yahoo groups increase
greatly.

Also, have you done any tests to destruction, on these new gussets and ribs
yet?

A big problem with polyurethane glue is deterioration due to water vapor
in the air. That is why polyurethane foam turns to dust after a few
years.

Hahahahahahahahahaha ...wheeze.. gasp

Good one, Orval, thank you. Best laugh I've had all week :-)

PS - Although relatively new in the United States urethane-based adhesives have
been used in Europe for the last thirty years or so, in the construction of
boats, houses and airplanes (for us common folk) but also for the repair of
antique musical instruments, the wooden tube of an antique telescope at Riga
and by the people who do restorations for antique furniture, firearms, coaches
(!) and so forth.

If you haven't tried it, perhaps you should. Or simply go read the FPL reports
on the stuff. It needs quite a bit of pressure to ensure a 100% bond with wood
but otherwise, it's a pretty good glue.

(Urethane foam degrades due to exposure to ultraviolet rays, not water vapor.)

Not true! Urethane foam will self-destruct in the dark! I had used some
for anti-chafing some years ago and it turned to dust.

Maybe we're thinking about different glues here. I certainly would like
to check out the FPL info on urethane glues.

How does it compare with T-88, good old Weldwood and Resorcinol?

Resorcinol and Weldwood make good joints, as long as you use enough
pressure, the joints make good contact and the curing temperature is
high enough.
