Gathered all parts for the frame of the elevator, assembled with clecos, didn't get photos of the assembly.
Match drilled two ribs to the elevator horn, one at a time and then assembled them together with clecos before riveting. Fit is very nice. Riveted the elevator horn assembly and when done test fit to forward spar joint of elevator. There is some mismatch with the horn assembly being a bit wider than the spar joint plate holes. Made a good stopping point, will consult with RANS for advice.
