I like to use Gorilla glue on robart style hinges. When you wet the wood first it really kicks off the GG and allows it to expand. When the hinge pushes through the backside of the hole, the GG does to and will expand and mushroom behind it. This adds a lot of strength when the hole is shallow. I've tested these hinges after a crash and found the wood to fail long before the bond, even when there is not a lot of wood to bond to but 1/8" might be pushing it
