This evening I just did some additional work on the rear spars. They're all done with the exception of adding on the top skins. I will try to get that done tomorrow.
One side note: while riveting the rear spar with the squeezer, I had to replace about six rivets. The hand squeezer kept pulling the shop head to the side and sheering it. I ended up using the pneumatic squeezer. Oh well...education and recreation...
