Silicon carbide wheel: www.amazon.com/gp/product/B0015YJB0K/ref=ppx_yo_dt_b_asin_title_o00_s02?ie=UTF8&psc=1
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. I followed this up with a 16 grit silicon carbide wheel.
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

- KINGSLEY NORTH -
Kingsley North is a lapidary store in Michigan's U.P. They make a great cab machine and sell many other brands too. They have a huge selection rough rock, tumblers, grit, jewelry supplies etc. at good prices. I buy most of my coarse grit from here in 45 lb. bags. It's the best price I have found. If you buy using the following link, I make a small commission.
