Assembled and riveted the left side spar. This one seemed to go a lot smoother. I realized I had the pressure set too high when I set the 1/8 rivets on the right side. I didn't have to drill out any rivets this time for the rivets set with the gun. I did manage one more smiley face with the pneumatic squeezers. The rear spars are done.
I took some time to clean up and reorganize the shop. I started to get things ready to start the main spars. I gathered material and laid it out on the table. I match drilled the end plates and then called it day.
