I riveted the main ribs to the main and the rear spars. Mark helped me drive some of the rivets. After inspecting all of the rivets, I dediced to drill out and re-rivet some of the main spar to wing rib rivets. The rear spar rivets went in with no problems.I then hung the right wing on the jig and carefully lined it up with the mid span brace. Photo 2 shows the fishing line going through the middle of the rivet holes, to show everything is straight and true. I also checked for twist with the plumb bob.
