Just thought I would post a few more pictures of me riveting the ribs to the spar. It's a little tricky trying to do this by yourself but if you slow down and think about what you can use to hold the parts for you it will be much easier.
I used several different clamps to hold the rib flange tight against the spar. Even used electrical tape to hold the nose rib back so I could fit the rivet gun in there with an offset shank. That thing makes me nervous but the rivets came out great.
