I use a hand held drill bit when drilling holes for Robart hinges. Hobbico makes a nice set with handles or you can improvise with a plain drill bit. I agree with you in that it would be easy to drill a hole that is not perpendicular even with a hand drill. As far as glue, I have used "hinge" glue and wood glue "TiteBond" without problems.

Remember to apply a little Vaseline on the knuckle of the hinge and immediately after gluing (before it sets up), flex the control surface a few times to insure the hinges are aligned.
