Made the aft (#5) former and the backbone. The backbone gets clips installed. Remade two of these because the hole patterns were not accurate enough to put them back-to-back on either side of the backbone. Probably good to make 3 of these brackets with the holes in the short flange, the other 3 brackets can then get match drilled to these 3. (F20-10)
Angle rivet tool I made.
How angle rivet tool is used.
Rivets where it was used. Allowed riveter access close to bracket flange.
