The next and trickiest step was riveting the trailing edge. These are double flush rivets and you back rivet them. The rivet technique is unusual but not hard. When you start the rivet gun the face of the rivet set is square with the rivet but not the skin. As the rivet is getting pounded down, you rotate the rivet gun so that the rivet set becomes square with the skin surface. I have the pressure set real low and it takes about three seconds to set the rivet. They all came out looking great.
After that you roll the leading edges and rivet them together and the rudder is done.
