Drilled out all four aileron attach brackets (A-406s and A-407-Ls) and re-primed. Bolted two of them to left aileron. Test-hung L aileron on wing.
Fabricated two A-914 aileron control stops from 1x1 angle in accordance with plans. (Hand-cut the angle stock due to odd behavior from bandsaw -- the blade would not track straight through the material, despite using a fence and being well-supported. I suspect it needs to be tightened a bit.)
The attach holes in the aileron spar must be drilled through, enlarged and deburred.
Aileron attach brackets bolted to the L aileron.
The aileron stops came out pretty darned nice, if I do say so myself.
