Brief Description: Riveting the left flap together
I first riveted the inner rib end rivets, don't want to forget them. I then riveted the interior ribs to the lower skin.
I placed the lower skin and ribs into the upper skin and riveted the join between the lower and upper skins, no small task for a guy with big hands. I used foam water pipe insulator to spread the skins apart to help. With hindsight it might have been better to rivet the ribs to the top skin first, doing the lower afterward, because I think the curvature of the flap 'leading edge' might make things a little awkward.
