Control horn installations..
Jim,
I'm talking about the ones where you have to drill both holes perfectly straight so it goes into the plastic backplate. It would seem easier if the holes drilled weren't that tight. Problem is drilling straight enough so the screws coming out of the other side of the control surface line up with the holes in the backplate.
The pin vise would solve the tight spaces issue but lining it all up so the holes match is still the other big problem.
