Clay you might also enjoy putting a TINY amount of that 15 micron CBN on a 1k waterstone of your choice Think of it in terms of adding a little nitroglycerin to your carburetors for it's effect. Here you are using the stone as partially a substrate and partially adding to the rate of slurry formation and partially to abrade the abrasion resistant steel faster. Also LISTEN to the change in sound.
