Set main spar on the wing construction jig and clecoed the two end wing ribs in place to set plumb line. Once everything was good and level with no twist, I started working on rear wing spar. Deburred edges of channel, the reinforcement fork and doubler plates. Clecoed and matchdrilled the doubler plate for aileron push tube opening. Notice the dates on the pictures are out of wack. I did not realize I had not set the date when I changed the batteries in my old style digital phone. Oh well.
