Thank you gentlemen for all the kind comments... the Excalibur Fence is very substantial (18lbs, 45" L, 2.5" H, and 3" W), I found a second complete undamaged fence on CL from an Estate Sale company in OH and bought it including the 78" fence rails (purchase and shipping was more that what I paid for the saw to start with but I wanted to keep it original). The Board Buddies were a package deal with the replacement fence system.
It takes some time to perform all the alignments, Sawsmith 2K itself (10 pages), then Rails and Extension Tables (each has it's own miter slot) then the Excalibur Fence adjustment for tracking on the rails, vertical clearance of the extension tables and parallel alignment to a miter slot and the saw blade. The good news was that all the components still had manuals available online or through Shopsmith.
After all that, it's still not the equal of a high-end, single role cabinet saw. As others have mentioned, there's a lot of movement associated with the engineering necessary to allow the saw to function in the Radial Arm mode. It is however a unique piece in my collection and more than adequate for my meager capabilities.
I'll take some additional close up pictures and post them.
