How to Sand the Flat Sides of a Rock

"Hi I'm Jason with Expert Village.com. We've done the first polish on one side of the rock, it's actually cutting not polish. Now we're going to go over the whole thing really quick with the same cutting bit, and I'm going to just keep the shape of the rock like I talked about before. And I'm not going to do anything with the edges yet. I'm just going to do the flat surfaces. So I'll get that all done on this step and then we'll talk about the edges and the different options you have and so we'll start with this right here really quick. Make sure you keep it cool all the time. OK now I've hit every flat edge on the rock with the first cutting bit. So we'll rinse it off, let it dry and I'll talk about edges next."
