I managed to put a little bit of time in tonight. I started to rivet the right side E-709 right root rib to the E-702 spar. These rivets prove to be a bit tricky since I find the rivets want to bent over more easily with the flat top yoke then if I used the other C yoke or standard yoke. I drilled out two of the four to replace and in the second drilling attempt...I joined the 'Drill through your finger' club. Ouch that Hurts. I finished riveting and called it an evening.
