This was my third finished mortar and pestle/ stone bowl. I've come up with a different way to create a "lathe" with the grinder. I am going to put to pipes on bearings mounted on the block of wood you see in the video. The friction from the grinding wheel will spin the piece like a cylinder and leave my hands free from touching the small piece of stone. I pan to do another larger one for the WellHaus pump basin that will also have a drain bored through it out to the greywater system in the future GreenHaus.
