Removed all tooling marks from Rear Spar Doubler (inside portions) using files, emery cloth, and unitizing wheel. Clecoed VS skeletion back together and clecoed on the skin. Match drilled all #40 holes on right hand side of skin. Remember those #30 holes I accidentally drilled into the Rear Spar Flanges, my plan to correct them is first to match drill #40, then dimple them to 3/32", then final drill them to #30 and use the oops rivets as planned.
