Tonite I deburred and dimpled the ribs for the vertical stabilizer. I also deburred the spars and spar doubler. I layed out the holes on the rear spar and rear spar doubler that are to get dimpled/countersunk on the forward side. Next I will dimple/countersink the spars. All holes were deburred using my avery speed tool, i use the extension twisted between my fingers for the interior holes. All edges were done on my scotch brite wheel mounted to my drill press and the small notches and corners i get with a hand file.
