Preparations for the final hole drilling in the Rt wing - rear spar, to 5/16".
Aligned rear spar and inserted a brass punch into the 1/4" hole, and clamped it with a large welding vise grip. Tried to align drill with the proper perpendicular angle of the spar, but drill will not allow it.
Two trips to the hardware to buy a better bit, and then also get a 12" extension. This will permit movement of the electric drill near the fuselage.
Ran out of time for the evening. (Drilled next day)
