After I finished drilling the rear portion of the tailcone skin, I started in on the forward section. I pre-drilling the F-606 bulkhead and the longeron. I left the center portion of the bulkhead undrilled since there is a gusset and rib that will also attach there. I can't fit the rib until I locate the canopy rail, so that will have to wait.
With the skin in place, I match-drilled some of the holes that I could get to easily.
