Tumbling Lake Superior Rocks from Last Summer

Last summer, I went to Lake Superior and found a few rocks. In this video, I tumble those rocks.

Here's the recipe I used to tumble these. It's the same one I use for just about everything.

Rotary tumble using coarse grit, such as 46/70 silicon carbide. Check rocks weekly and set aside any that are acceptable. There is no set time for this. Each rock runs as long as necessary.
Lot-O Tumbler:
2 days with 2 Tablespoons 220 or 120/200 silicon carbide grit
3 days with 1/2 teaspoon 500 aluminum oxide grit and 1 tablespoon borax
2 days with 1/2 teaspoon aluminum oxide polish and 1 tablespoon borax
Optional: burnish for 2 hours or more in 2 tablespoons of borax

– 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.
