I ran across this video on Facebook, Grinding hearts. He uses one hard wheel, doesn't say the grit, I'm assuming an 80. He goes directly from that to a soft resin 60 then a soft 140 and 280. Then he mentions going to a 600 and finishing on a 15000. What intrigued me the most was how he went from the hard wheel, with a large flat spot in the dome, to the 60 soft and takes the flats right out. |

That guy (Russ Kaniuth) writes a column in Rock & Gem Magazine, called " What to Cut" . He seems to specialize in cutting hearts.
But he regularly gives different sequence of wheel use, than a normal cabber has.
Obviously he has multiple units.
He offers some good tips though and I regularly look up his old articles if I'm cutting something different,
and have saved a binder of his magazine articles.
Here's an example - having just seen Jason's Malachite cabs, I was reading Russ's article about cutting it.
He suggested Zam at the end, for a polish, not Chrome Oxide (which is what I would have used).
I guess maybe because it can undercut ?
I need all the tips I can get.

Everyone has their own grinding preferences. Mine has changed over the years. With heavy use, soft wheels don't last very long. When a person is selling, they can use the equipment that gives them their best results. I replace my 80 grit early because I spend more time on it than any other wheel and am not getting paid by the hour.
