Not much warmer today but I began the back drilling and drilling the snap bushing holes. Cut the tail tiedown bracket and horizonal stab attach bars. Cut various angle pieces. Pulled 4 pieces of long angle from storage. Called Vans to make sure they were to be cut. Only neede to stay away from the Longeron pieces. spent a great deal of time drilling and dimpling the F712 A&B bulkheads. The edger were pretty rough so I needed to ease the sharp corners and debur the edges. Next I went to the F711 A&B. A piece needed to be cut out of both for the elevator push tube . Made the attach bars for the horizonal Stab. The F710 requires an angle stiffener to be fabricated and match drilled to the top of the bulkhead. the top edge needed to be eased to match the inside curve of the longerons
