I polished a large Charlevoix stone for my friend Bill. I also re-polished a large Petoskey Stone at the same time. I’ll show you the process I used.
Here are the steps I took to polish this:
I started with my normal, dry angle grinder with a diamond cup wheel. The cup wheel is 50/60 grit.
Next I moved to a Makita electronic stone polisher. This has a soft backer, so the pads can flex to the shape of the rock. The grits are as follows:
30 grit
50 grit
100 grit
200 grit
400 grit
800 grit
1500 grit
3000 grit
6000 grit
8000 grit
