I was wondering about what order to attach the rudder wedge and rib when riveting them in place. The manual didn't say anything about it, so I think it really doesn't matter if you do the rib or wedge first since either way you'll run into a tight fit when completing the rivets. I used the buck bar inside the hole of the wedge and held it in place with my fingers while riveting. I did slip a little bit and dinged the edge with the dreaded "walking riveter". I smoothed it down with Scotch-bright then gave it a squirt of primer before moving forward. Very tough area to rivet, so make sure you pay attention to both sides when doing it. I did end up with a couple of "smiling" rivet heads. Probably ok with enough "meat" but I'll replace them anyway.
Riveter "walked". I smoothed it out again and re-primed this area.
