Ever have one of those days on your project where you just throw down your tools and say "I'm done for the day". Had one yesterday. I'm working on a QB RV-7 kit trying to attach the A407 / A406 aileron brackets and keep gouging the holes in the end ribs of the ailerons. The pilot holes in the ailerons are about#30 and I need to drill them out to the final 3/16" size for the AN3 bolt. But every time I try to drill them, the drill bit grabs on the aileron spar, thrusts forward and bends/gouges the hole in the flange of the aileron tip rib. I've tried clamping everything tight with cleco clamps and starting with small size drill bits and working up to 3/16", but still having problems. When the drill bit grabs it's like the drill leaps out of my hand. The only other thing I can think of is to try to use my drill press so I can control the plunge of the drill bit.
Any ideas?
