I had enough time to get nuts torqued onto three of the four attach bolts for the forward spar of the horizontal stabilizer. Reaching into the fuselage through the lightening hole in the aft deck was excruciating, but since I didn't find a gnome with long arms in my travels today, I had to do it myself. Using a combination of 1/4" drives handles, 12-point sockets, extension bars, worklights and a mirror on a flexible arm, I managed to get the job done. The fourth nut will take another half-hour of effort tomorrow. I just had to take a break and let my forearms heal overnight.
See photos 2 and 3 for a description of a helpful tip I highly recommend if you're trying to do this job on an early-model QB fuselage with the top skin already in place.
Photo 1: Attaching the forward spar is easier if you lightly glue the nuts and washers together...
Photo 2: ...so you can insert them both into the fuselage together and not lose the washer off of the socket.
