Tonight we finished up the last few rivets on the firewall and riveted on the doubler plate. After that we started work on the bulkhead where the wings bolt to the fuselage. Needless to say this is the heart of the fuselage. We started off by drilling some holes for bushings (essentially little pieces of plastic that protect wires or cables from rubbing on the metal and chaffing). After that we assembled the forward and aft portions of the bulkhead using the close tollerence bolts (and are they ever close tollerence) and clecos. We match drill something called "shear bars" to the aft portion of the bulkhead and then finished up match drilling all of the parts. Things went smoothly so we made a lot of good progress.
