Seatbacks: Started riveting. I don't have a longeron yoke (yet), so had to do some of this with the gun and bar. To make it even trickier, I managed to put the holes in the side angle too close to the flange, so the rivet set is tight up against it. I ended up putting in some smilies. Ah well. I left the second seatback for now. I'll get back to it when I get a longeron yoke.
