Hello Stefan. And thank you for looking at the noob flailing his way into a first jnat.

My understanding of swarf is that it's powder fine slurry composed of tiny metal bits produced by abrasion. When I backed way off on the amount of water I was using, I could see swarf. When I used more water, I could see the appearance of a white, milky substance that I'm thinking is slurry from the stone itself. I see both now when I use very little water.

Any thoughts you have on the experimentation/testing is very very much appreciated.
