RE: gluing hinges
Pacer Hinge Glue
None of the problems of epoxy and it holds just as good. No way I'll ever epoxy a hinge again.
It is dead easy to use. It won't ruin a single hinge and stop your build dead in the water. If you smear any of it on the airplane, it wipes off with a damp paper towel. Try that with epoxy. If you get any on your hands, you probably won't have an allergic reaction as some do with epoxy.
