FACETING HEAD AND MAST

The faceting head and mast may be purchased separately. Faceting heads and mast for the Mark I and Mark IV are designed and manufactured to the highest standards thus insuring the accurate grinding and faceting of the gemstones. The stainless steel dop spindle is machined within a concentricity of 0.001 inches and the double set of sealed, precision, stainless steel ball bearings insure the accurate grinding and polishing of facets. The mast consists of a 5/8" precision ground, stainless steel shaft which is pressed into the base plate. The base of this entire assembly is then machined square with the mast to assure proper alignment. A radial vernier (cheater) permits micro rotation of the dop to completely polish a previously ground facet. The faceting head can be set to a free-wheeling position which permits preforming of the stone by continuously rotating the gem at a specific angle. A chrome radial vernier (cheater), and an engraved 32-toothed index plate, to make learning easy, are standard equipment. The Faceting Head tilts into a spring-loaded locked position for quick stone inspection, or the entire head can be easily removed from the mast. The Graves faceting head includes an angle indicator with a 1/10 degree vernier for accurate measurement. Please allow 3-5 weeks for delivery
