Brief Description: Flaps - Rivet aft end of ribs to folded spar
Then I riveted the aft end of the ribs to the folded spar. But I had only drilled these to 3/32 so I had to re-drill them to 1/8 and re-debur. Then I riveted. I used a bar clamp with light pressure to hold all the parts snug while I squeezed the rivet.
