Riveted the rudder stiffeners. Bent the trailing edge using the shop made brake and hammer forming around the bending dowel.
Match drilled the ribs and spar. Dimpled.
Assembly of the lower rudder rib and control horn went smoothly. Riveting R-710 was somewhat difficult. We ground down a bucking bar to fit inside the assembly. We were able to buck all but the most forward rivet, which we pull-riveted.
