Today I finished the pilot's seat back. I do not know why this took so long to get done. They are really straight forward. But it has taken much longer than I imagined they would. I guess it is working with the piano hinges and trying to make sure everything is aligned properly that takes so long. In any event my goal to day was to get the seats done and the center tunnel cover.
I fabricated the second support today, replacing the one I messed up a few weeks ago. Then it was pretty easy to rivet the top skin on to the two supports. The final step was locating the forward hole, drill it and put a nut plate in.
The next goal is building supports under the arm rests and finish the forward cabin area.
