Finish deburring stiffeners.
Final drill and deburr skins and stiffeners.
Dimple and prime stiffeners.
While the primer was setting on the stiffeners, dimpled all the aileron skins.
Started back riveting the aileron skins, getting the left top and bottom done.
Did a quick assembly of the left skin/spar/ribs. There are two 3/32 rivets attaching the rib, spar, and reinforcing plate. But the reinforcing plate hasn't been drilled yet. The instructions don't say anything about them, other than to use those to attach the ribs.
So it appears the reinforcing plate needs to be match drilled with the spar, then the rib is final drilled with both.
