Trace,
Thanks for the kind words.
I use the 3M 977 Ceramic belts, 50 up to 120 grit, to rough grind Stellite. The problem comes in after than. Ceramic belts do a great job but you can't get the 977 any finer than 120. I've not found a belt above 120 grit that will not dull almost on contact with the 6K. It just takes time and belts to get to a 400 grit finish.
I use the Ceramic Bead to bead blast. It works well. On hand rubbed finishes, I go to the 400 grit on the grinder and then go back to 220 paper and work up to 400 grit.
My advice is to experiment and find what works for you.
