Spent about 1/2 hour working on the aileron bellcrank clevises. They were too tight for the 1/8" thick bellcrank, so I found some .010 aluminum stock to make a spacer. This measured out pretty well on the micrometer, but the actual assembly was a little loose. May need to find a way to thin the shim or maybe the spacer itself. Spent the remaining time drilling the LH wing. Drilled the bottom side to 1/8" size including the flap hinge. Deburred the leading edge ribs where they attach to the spar.
