  • Sharing a Passion for Rockhounding (Part 1) Rock Gem

    Several years ago I built a grinding unit out of wood and used a 1/2" arbor with a 100 grit grinding wheel. It was messy throwing off water and needed to be constantly redressed with a diamond dressing bar. For some reason I felt that a diamond wheel would be too slow compared to the silicon carbide grinding
