Here's another picture of the underside of one of the hinges. No glue at all, the dark area is the small amount of glue and balsa on the top side. The balsa that is stuck on the hinge is very thin, again it looks like the glue did not wick at all into the hinge and slot. Live and learn, lots of good advice presented so far and if the crystal ball wasn't in the shop getting fixed this week I would have done some of them. Sometimes you just have to make a joke and laugh about it. Thanks for the kind words.
