Made firewall spacers and drill them and hinges. That was not entirely successful. I positioned one of the hinges too high up the side skin, so the match drilled hole into the hinge missed completely. Had to make a new hinge piece. Riveted left side skin in place. Eventually completed Section 23
Completed forward fuel return line. Trial fitted rudder pedals and left hand seat back. Established that I could not reach full rudder, so installed another seat back hinge 2" forward of the forward location on the plans.
Tried to comjplete a few other things but just kept going wrong so we quit while we were ahead. Don't work on your aircraft on Friday 13th!
