Hi Dan
 Actually, talking to Bratislav, he may have convinced
me to give it a try. I'll get the hardest steel I can
find. The bearing rings from truck wheels should be hard
enough to not embed the grit and they come in about the
right sizes. Like I say, I believe the major benefit
of using the rings is increased PSI on the grit.
I'm going to check with some local truck repair shops.
I still have a lot of glass to remove so I can experiment
some as long as I don't drop something.
