Deburred lower aft skin, upper aft skin. These went pretty quick since it was just the forward row at the main spar plus the inboard 2 rows at the root doubler. Deburred the root doubler and clecoed it to the upper and lower skins to drill through a few holes that I didn't get (can't get the ones at the spar, and didn't get the ones at the aft spar until here). Cleaned the marker lines off the outside of both of these skins. Sprayed primer on the inside of both of these skins. Put the leading edge skin on the table and drilled the hole for the pitot tube and the attaching nutplates. Dimpled the rivet holes for these nutplates. Plan to c-sink the nutplates themselves for the rivets.
