Yea... a bit of deburring, and we're clecoing the bulkheads together via the ribs and the bottom skin. it's a bunch of match drilling, not too difficult. we're basically building the area between the wing spar and where the tailcone would start. it's kind of the back seat area, and the baggage area. at certain points, you'll see me in the pictures standing in between the ribs to get access to rivet. woohoo!
