DIAMOND WHEEL AND 600 GRIT SANDING BELT You will need a 600 sanding belt and an 80 grit diamond grinding wheel set up on a lapidary machine that supplies a constant stream of water to the surface of the belt and wheel. The water serves as the lubricant and prevents the stone from getting hot from the friction of the wheel. Again, set your lapidary machine up according to the instructions. Take the slab of stone by your fingers and begin shaping the stone with the diamond wheel. Then move to the 600 grit sanding belt for a smoother finish. This belt will help get scratches out from the diamond wheel.

Be very cautious not to get your fingers against the surface of either wheel. It will cut and take skin off very quickly. Move from one wheel to the other, shaping and smoothing, until you have your desired shape.

BUFFING WHEEL
Though it is not necessary, you may want to give your stone an even more polished look by going a step further and using a Buffing Wheel and one of the many stone polishing compounds available.

These are very simplified guideline for beginning lapidary projects. There are many ways to do this. Anyone interested in the art of stone cutting should familiarize themselves with as many instructions books as they can. It can be a rewarding hobby or profession for anyone who loves rocks.
