For pinned hinges, I've always had an issue with the glue being wiped off the hinge as you insert it into the slot. It always made me leary of the amount of glue that is actually in the slot.
Back when I built a PT-40, I used Dubro hinges. Manual suggested using a soda straw with the end flattened to do this. Scoop up some epoxy with the flattened straw, insert it into the hinge slot, blow. Worked pretty well
