Enumerated and cleaned the parts for the elevator. Cut some L-Angle profile for the rib-to-inner channel attachment. On Thursday I fit the ribs and channel into the skin and drilled/cleco’ed the front and underside. Ran into a bit of a problem when the channel was too wide and hence the ribs would not line up. I finally worked everything out so the rivet edge-distance in the inner ribs is acceptable and things ended up fitting.
