finished riveting the middle rib and front spar to the skin. Replaced the bottom rib and riveted it in place. The rivets that connect the rib to the spar web on the front spar are a bit difficult because the lightening holes in the rib interfere with the rivet gun. I don't yet have a pneumatic squeezer, and the 1/8 rivets really mess with my carpal so I have been using the gun. Squeezed rivets come out nicer and more consistent, but my gun work seems to be okay. On to the Rudder!
