I used the steel I cut yesterday to improvise a bending brake, and bent the two bottom wing skins. Then I used those bottom wing skins and the aft spar to align the aft ribs and attach them to the spar. Then I started drilling through the ribs and skins to cleco them together from the inside out. This worked well until my drill bit hit a screw in the table and destroyed itself. But the basic idea I think is good...this way I know exactly where on the rib the rivet will land. Now I just need to find some new threaded drill bits for my right-angle drill.
