ABC's of ShopBot CNC - Letter "r" - Soapstone

Soapstone is a metamorphic rock that is easy to carve with exquisite detail on a ShopBot CNC machine. In this video, we carve a 3D map of the moon’s surface. Many ideas are brewing for larger scale projects with this material and we would like to see what you can do with it on your ShopBot!

Produced by John Kuiphoff in partnership with ShopBot Tools.
