Still riveting, added in another dozen or so. Need to pick up the pace or it will never fly. Hmmm, just noticed something. I am riveting on the left skin, yet I notice the hole I drilled in the spar for the trim cable is on the opposite side. *&@*#*!, I riveted the left skin on to the right side of the skeleton! After looking at this large pile of aluminum for quite some time, I had a revelation (I hope). Matched hole tooling! If you ruin a skin, just get another and it should fit. Well, supposed I’l l just re-mark Left and Right and move on. Next, I clecoed the Right skin to the skeleton and clecoed in the rear spar as well. Everything fit without any issue. “Matched Hole Tooling” saved my bacon!
