Brief Description: Rivet stiffeners to rudder skins!
Took the rudder skins and back riveted the stiffeners to them. Made a small mistake and got about 3 or 4 cycles of the 2x gun with one of the rivets off the back rivet plate. A slight outward pillow in the skin. 63 rivets per skin for a total of 139 rivets down.
Did the left skin 2nd. Came out real nice. Ice is broken with the 2x gun.
