Drilled W11-09 to the RH spar. This is the 3/16" angle along the lower inboard side of the spar. Also cut the 1" x 1.25" stock to length for the wing pin blocks. This seemed intimidating because it was so thick, but went really well by taking it slowly.

Other side - rounded off two of the chamfers to get good fit to the mating part.
