Brief Description: spar riveting revision to method
As I was riveting the rivets near the rib attach angles, I found some interference between the angles and the big block of steel I had my universal head rivet squeezer cup mounted on. So I removed that assembly, put on the revolving base plate that came with the arbor press, and installed a base removed from a C-frame dimple fixture. This gave me a narrow post to mount the squeezer cup on, allowing it to get much closer to the rib attach angles.
