Back riveted all R-815 (A-H) right and left stiffeners to the R-810PP rudder skin. Built a trailing edge folding/bending jib out of two 2"x8"x60" hardwood boards hinged together with 3 door hinges and padded with felt. Bent the R-801PP rudder skin until surfaces were straight when measured with a straight edge while R-802PP rudder spar was clecoed in place.
