After a few day’s break, I spent a couple of hours working on the rudder today. I started with a practice piece to get the feel of a new rivet set, and the double-back riveting process. Then I set up the rudder and riveted the trailing edge. The instructions call for partially setting the rivets initially, then going over again to finally set the rivets. All the while checking for any waiviness or distortion. After the initial setting, everything looked good, so I went back and finally set the rivets. I was happy with the results, very straight edge, and skins nicely mated. There is probably some amount of warp, but nothing worth worrying about.
Great that you have the back of the rudder together and that it’s looking good
