Small and Lightweight. Footprint is 35 cm wide x 29 cm deep x 18 cm high,

Generates little heat - ideal for Opal, Turquoise and other delicate stones.

The spool is made from a phenolic resin, exclusive to the Graves machine, and will not warp, crack, or chip. It generates very little heat making it perfect for polishing softer gemstones. The spool is manufactured to accept 6 different grades of diamond compound an designed so you can polish either flat or curved surfaces.

To use the Spool Polisher just take a dopped cabochon that has been ground/shaped on at least a 220 grit grinding wheel and apply a dab of 325 grit compound to the first section of the spool. Work the stone into this 2 inch section of the revolving spool. The gem is then wiped clean and 600 grit compound is applied too the adjacent section. The process is repeated (with an occasional drop of extender fluid) until all six steps have been completed. It only takes a few minutes and after several cabs have been completed, the spool will become charged and only an occasional drop of extender fluid will be needed to re-charge the unit.

Complete unit includes:

1 gram each of 325, 600, 1200, and 8000 grit diamond compound

2 grams each of 14000 and 50000 grit compound

2 ounces of Extender Fluid

0.12 hp motor (0.09 kW) with 3 pin Australian plug
