Drilled bottom side of forward wing skin. Went back over it to get to final hole size. Used #30 on the spar and root doubler holes, .125" drill on the other (to be dimpled) holes. The root doubler gave some difficulty - needed to squeeze in the leading edge radius quite a bit to get the skin to sit down on the rib. Disassembled the wing. Unclecoed a few of the aft ribs to give access to finish off drilling the root rib to its forward bracket. Deburred the spar. Deburred the forward ribs, drilled them for the electrical conduit, installed the grommets for this. Dimpled the forward ribs. Deburred the root ribs all around. Added gussets to the root ribs. Riveted the root ribs to the spar, finished W17. Clecoed all the ribs back in place, and riveted the aft spar to the aft ribs. Installed the hardware for the aileron pushrods to the aileron bellcrank. Deburred upper aft skin and wing root doubler.
About 280 1/8" clecoes all spread out (drilling done).
