Brief introduction with my voice!
It's dirty, oily and gross... but that's how I prepare and process rocks. Mineral oil is the medium for cutting... water is the coolant for grinding and polishing. Support your local lapidary club! 12" saws are around 2000 dollars.. trim saws are another 800, and a good cabbing machine, lortone or cab king are at least 2200. It is quite an investment. Plus consumables.
