Finished drilling holes in left ruddervator. Deburred all holes. Clecoed and riveted all ribs to elevator skin. Riveted hinge to elevator after ribs were fully riveted, Used 42-ccp rivets. Had some challenges with the pneumatic riveter, however, got it figured out. Christian and Lora did some of the rivets.. Had to drill out 2 rivets. Boy, those rivets are stong!! Gives me confidence that this is going to be one solid plane!
