FOAM SAFE CA
Personally I prefer the flat style of pinned nylon hinges like Sig , Dubro or CG.
I fold the hinge closed & use a toothpick to put a little oil on the rounded edge. This keeps excess glue from sticking there. Then put 30 min epoxy in the slots. Also "wet" the surface of each hinge with epoxy before insterting them into the slots.
You can flex it a little to make sure of alignment, then let it harden a few hours and when you first flex the joint it will crack loose any glue that may have gotten into the joint.
Robarts are easier and very nice too, but you need a few more of them to achieve the same amount of glue contact area to the flying surface.
Have also had excellent results with the CA style, but if you have a foam core, be careful to use CA that is compatable with foam. I had some "oderless" CA one time that ate foam like crazy!
