Just chipping away at whatever I can. Decided to build the rear seat backs today. Quick inventory though confirmed that I'm short some of the angle stock I need. I can build one of them at least.

Cut the angles to the required length and laid out the holes in the seat back. Match drilled the side angles to the seat back with a #40. The top angle has to be shaped to remove the vertex from the angle so that it will fit under the bend at the top of the seat back. This was a bit of a challenge but just had to work with a few different files and belt sander to smooth it down. Pretty happy with the fit. Then laid out the holes for the top angle and match drilled everything to the seat back assembly. Trimmed the hinge material for the bottom and aligned everything in place and match drilled.

Once everything was match drilled #40 and cleco'd together, I final drilled everything to #30. Then deburred everything.

Fun little project with a lot of fabrication. I think the seat back is basically the same as what is in an RV-6 and it was fun to get a sense of what it was like for those builders that didn't have any predrilled holes. It came out really well.
