I received my new clecos the other day but this is the first chance I've had to get back to the project. So today I celcoed the F-1074 in place and then finished match-drilling the top stiffeners. Once that was complete I then final drilled both top skins to the frames, bulkheads, and longerons, skipping the F-1006 (the baggage bulkhead) which gets drilled when the tailcone is mated with the fuse.
