Brief Description: Riveting the rudder trailing edge.
The trailing edge is riveted with double flush rivets. These are standard rivets, but instead of setting the shop head on a flat surface, it is set in a dimple and ends up flush with the skin surface. I numbered the rivets 1 through 12 , and alternated riveting them to help insure the rudder stayed straight. Lucky for me, it came out straight. look at the pictues, notice how well the shop head turns out.
