Finished riveting the top skin to the main ribs. I had one bad rivet that needed to be replaced.
I set up the next step with digital levels to measure any twist in the flap, but both of the levels read the same so I don't have to do any adjusting. It was dark when I finished so I'll defer the noisy riveting until the next session.
