From what I hear carpenters glue does not go well with moisture, and weakens
under humid conditions. I have found that T-88 makes one heck of a bond,
it's a two part epoxy. How well it holds up after years of flying, I don't
know yet ..have not gotten there yet But there are several Volksplanes
flying that have been made with it and are doing great.
As Mr Morgans pointed out..brittleness. It seems from what I have read
on that subject it really plays a role in any kind of a gap between parts.
The glue just shears right at the joint. I am a pretty good woodworker , but
I don't know if every single joint would be as perfect as needed in order to
offset the brittle shear effect. Wouldn't advise anyone else try it either.
