Today, time was spent tweaking the bulkhead flanges to provide a parallel surface for the skin attachment. Before I could start, I had to make a new flange tweaking tool, because I could not find the old one. I spend way too much time looking for tools that I had in my hand 30-seconds ago. Very frustrating.
The left and right skins were clecoed in place, and the rivet holes for the side stiffeners and bulkheads were reamed to #30, then the skins were separated and the reaming chips cleaned out. All of the side skin stiffeners were then riveted in place.
