So I am countersinking my flap and aileron spars right now. I understand that the holes will be a bit knife edged in this .040" material but i am also ending up with out of round holes on the bottom. Does everyone have this issue? Should I get a #37 or #38 reamer and try to round out the holes?
Kind of regretting not dimpling them despite the instructions saying to countersink. Just took a Boeing repairs class and this would be an absolute no no by their standards.
