Has anyone run across any pictures or other information showing the riveting technique for attaching ribs to the tubular spar? In order to replace a rib, you must remove the attach bracket. Obviously splicing the aft portion is an option. But it leads me to ask how they built the thing. I am guessing they had a very substantial bar that ran through the entire tube, supported at each end. Then they would slide each rib, already riveted to the bracket, and then rivet that to the tube?
Seems logical but it sure would be useful to see some actual documentation.
I would assume it was some form of a large dia round bar slid through the the tube.
The trim spool casting would be the interesting roadblock.
