Started on the F-706 bulkhead by locating all the pieces and doing the edge treatment, bending and fluting the flanges. Found out later that I had bent the flanges in the wrong direction, because I failed to check the orientation of the bulkhead and assumed that the flanges faced the rear as the previous bulkhead, which turned out to be incorrect. Toughest part of the job was drilling and enlarging the holes in the bottom of the bulkhead for wiring and tubing, because the holes overlapped the edges of the baggage ribs on the front side and the bellcrank channel and rib on the back side. Pita can mean more than a type of bread. One of the holes "walked" on me while I was using the step drill on it, wound up albout 1/16" off center, and it was dead on when I drilled the first hole to start. I drilled the plate and the lower bulkhead section by themselves to start, since the holes were entirely inside them, then clecoed the ribs and channel in place and match drilled them on the edges that protruded into the hole. Then step drilled the whole assembly together out to 5'8" and clecoed it all together.
