Bobby - after I 'penned' my response to Randy, I removed a worn out solid edge 7" saw blade from my tile saw and may just see if I can make that into a shrinking disc. There is still a tiny bit diamond grit on the edge, but it may come loose with some heat and may anneal the disc enough to be dished a little bit. Low on my list of things to do though :-/
