I got all of the solid riveting done, between today and yesterday (this post covers both days), on the left main spar EXCEPT for I ran out of rivets only 25 holes from the end. I will move on and finish it once they come in. I ordered them 2 days ago when I realized I had a peculiarly small amount of them. I got through half of the spar and it was still straight as an arrow. In that last 3-4 sections it started to bow as almost all of them do. The picture looks worse than it really is. The illusion of the spar angle relative to the table makes it look like worse.
I did a nice clean up of the shop after these pictures and re-oprganize the garage a bit. I plan on adding an air hose reel tomorrow if I can.
