I clecoed all the main ribs to the main spar and the rear spar for the left and right wings and then match drilled both the main spar and rear spar. The ribs were removed, the holes deburred, all the main ribs were inspected, and then all the ribs were primed. After the primer had dried all the ribs were clecoed back to the main spar in preperation for the next session of riveting all the ribs to the spars.
