I was able to get a little time in the shop today. I riveted the 4-12 and 4-8 rivets into the wing attach of main spar number 2 and the splice plate of main spar number 2. I did my first flush rivets today as well with 4-11 flush rivets to hold the wing attach spacers in place. I still need to do the flush rivets on main spar number 1.
