I use 5 min epoxy in a syring. A little bit of oil on the hinge it self (not on anywhere being glued). I put a tooth pick in the end of a syrenge, mix the epoxy, pour it in, squese it into the control surface insert the hinge, and let all the hinges touch the table to make sure the length is correct. Then flip the hinges down to make sure they rotate the same path then hold the control surface again to make sure they are all touching again. This also allows the glue to pool at the hinge.

5 Min workes fine and you don't have to wait for ever. I have always felt the strength issue between 60min and 5 min epoxy is bogus. The strength difference is marginal and the wood is by far weaker anyway. If 5 min won't hold it there is something wrong with the construction.

If the hinges are glued in this way, they can be a bear to get out. To remove Robart pin hinges I first cut the hinge cutting the control surface off with a hack saw blade. Then find a piece of brass tubing that barly fits over the hinge. I cut the end of the tubing like a saw with a dremmel tool. Drill a hole in a piece of wood for a handle. Drill pilot holes and insert screws in the handle to hold the brass. If you don't use a handle, you'll get blisters if you have a lot to do. Push this around the hinge and turn. You'ss see just how well these bugers are in there:



Fill with expandable foam and finish with lightweight filler.
