While waiting for Kriya to be available to help shoot skin rivets, I decided to move on to something else. Reading ahead in the instructions, It seemed like one obvious thing that didn't depend on completing another task first was the seat frames.

I will say, that for an assembly that's so dirt simple, these took a remarkably long time to fabricate. Nothing is pre-drilled, so there's a ton of measurement, fabrication & layout for the frames before you match drill everything. There are also 4 places where you're required to file a .040 relief in the 4 vertical frame members to allow the lower piano hinge to nest properly.

I made this relief with a vixen file followed up by a 3m wheel to take the file marks out. There was lots of back and forth and frequent measuring against a piece of .040 scrap to make sure I was in the ballpark without getting them too deep. The upper cross brace has to be radiused so that it will nest inside a bend on the seat skin and I followed a similar process for that.

At this point, all the component parts are fabricated and match drilled. They just need to be de-burred and primed before being riveted. I debated on whether to prime this assy at all, since it's just seat backs, but aluminum oxide will rub off and turn all kinds of stuff black over time, so I'm going to prime the non- alclad frame member to keep this from happening.

I think that when I order an interior, they come with their own seat frames, so I don't know how much use these will get, but this way I'm not being so schedule driven to order interior.
