I use 30 min epoxy for the pin-style hinges. Lightly sand the hinge leaves and the epoxy bonds to them better.

Before applying the epoxy... grease the hinges. I usually take a size 0 paint brush an apply vaseline. do not get the grease on the main areas of the leaf... just the portion that is supposed to be able to move. the grease will prevent the epoxy from bonding to the area where you apply it. (never glue a pin type hinge into a fixed position again.)
