Lapidary Time!!! Shaping and preforming stones for the tumbler pt1

In this video I grind slabs and rough stones for over 3 hours using my Hi-Tech flatlap to hog out alot of material fast using a 46grit lap and then my Loretone grinder at 80hard/80soft to further shape and preform the stones finally I put the stones in my Harbor Freight Chicago Electric Tumbler with 80 grit silicon carbide tumbling grit and some plastic tumbling pellets I also chat a bit about Thumbler Tumbler and DuraBULL tumblers
