Today I fabricated a couple of brackets and spacers that attach the aft deck to the F-710 and F-711 bulkheads. This is also the primary attach point for the horizontal and vertical stabilizers, so there is a fair amount of aluminum here. One thing I found was that I should have attached the F-710 bracket to the bulkhead BEFORE I riveted the bulhead into the fuselage...no big deal, but drilling it was a little interesting. Waiting for a warmer day to prime, then I'll rivet the aft deck in and move on to the upper fuselage skins...or maybe the firewall gussets...or maybe the static lines...
