Maybe my memory has faded over the last 18+ years, but I don't remember the drilling of my -8's aileron counterbalances to be as challenging as I'm finding it to be for my -14A.
I've already broken one good cobalt drill bit and am probably on my way to losing at least another couple. I've been trying to keep the speed (both RPM and advance) slow and it's just occurred to me that using cutting fluid might be a good idea.
Any other suggestions on how to do this more efficiently/painlessly?
