I Tumbled Rocks Nonstop For One Year!

Yep, that's right, I put two barrels of rocks on my tumbler and didn't touch them for an entire year. The results were very interesting! This experiment really does a good job of showing the strengths and weaknesses of silicon carbide and aluminum oxide grit.

Highland Park makes some high quality tools at reasonable prices. I have two of their tumblers. They're the most rugged tumblers I have seen. They also make a wide range of other lapidary tools, including saws, sphere machines, cabbers, etc. They also have the best price on grit that I have found.
