Positioned and riveted inboard ribs to inboard spar. Positioned hinge brackets with 26mm extending above inverted skeleton. Drilled holes to spar and nose ribs. Marked angle from spar to inside corner of brackets. Disassembled brackets and rough cut the angle with a hacksaw. Finished up the angle with a scotchbrite wheel on the grinder. Reassembled and riveted brackets to skeletons. Unlike the wings, I'm doing both sets of flaperons at the same time.
