GEMMASTA FACE PLATES
Gemmasta makes a variety of face plates to fit their own as well as most commercially available machines. Face plates come in 150mm (6"), or 200mm (8") diameters.
Right hand face plates are designed to run on the right hand side of your machine as you face it. Left hand face plates go on the left hand side of your machine - they are NOT interchageable!
Lapidary machines are manufactured with a variety of shaft (arbor) diameters. Shaft sizes for commercially manufactured machines are alway imperial (not metric) and the most common sizes are 1/2", 5/8" and 3/4"
These face plates are first cast and then machined for true balance.
