Thank you, did not think of the water supply. I was using tank water. Could have had some bits in it. Change to town water and wash down after each session. A session lasts four lots of 15 min polishing with 20 min cooling of the motor. I will change the motor setup, so it won't heat up and I can polish/grind as long as I want.
Looked at the CN link and it gave me some idea on how long it takes to polish and I am nowhere near the times they say. Thank you for that. Might ask the cerium supplier the particle size of it.
