Looking good David.
As mmcmdl (aka Dave) said, when you grind hardened parts the finish is incredible.
I think there is a bit of witch craft involved in surface grinding.
Grinder hands can share their knowledge but for me, the right wheel (there are only 10,000 to choose from) a fresh dress with a final pass of .0002” with a small step over, spark out.
It’s like a mirror finish.
This Norton ceramic was expensive but man, what a high quality wheel.
Balanced and it has made me a believer in ceramic.
