Today I finished de-burring and fluting the balance of the aft ribs, after much consideration I decided to install thes skins and matched drill the right wing. it makes sense to me to do all the ribs preparation and then dimple them before priming. All the matched drilling being done on the right wing, I clecoed the skins to the left wing. Had to drill the wing walk doubler.The plan is to have one day of priming and then assemble.
