Cut out some clips from some left over RV material. I love using that stuff as it forms a connection from my last plane to my next. Anyway, trimmed them down, deburred the edges and then bend them around the tubing using the vice to pull them to one side, so the seat back will be flush with the tube. Drilled them, then clamped them onto the frame with the seat back and match drilled them. Took it all apart, deburred the edges and then riveted them together. Used the squeezer for the first one, and then shot the other, since I couldnt't reach a few rivets with the squeezer, and I didn't want to go back and forth. New tv for the hangar arrived, and I put it in the shop.
