Picture 1 shows a pair of seatback hinges riveted to left seat floor. Note the unriveted holes in the further away (front) hinge which co-incide with the seat ribs. These will go in when the seat floor is riveted to the ribs.
Picture 2 shows the floor riveted to the ribs. You can see where the seat belt attach brackets protrude through slots in the seat floor.
As noted previously, I had made a mistake with one of the hinges on the right seat. I riveted this on such that the holes lined up. Unfortunately, this was the underside of the seat! I must have fabricated the part by attaching it to the underside prior to drilling. So out came the rivets, and I had to remake an additional hinge, prime it, and fit it correctly. Stoopid mistake ;-)
Picture 3 shows the underside of the fuselage standing on its tail end. Structure is a getting quite heavy and is a bit floppy at this stage. The addition of the skin (soon) should stiffen things up.
