Gearloose Lap Application Charts

These tables are suggestions for use of the various Gearloose laps.

They are based on experience reports from a wide variety of faceters, from beginners to competition and production cutters, and reported on from the Faceters’ forums online over the years. All individuals use differing techniques, with variations in lap speed, pressure, wetness, and sweeping rate, so these tables are suggested starting points.

Brief Summary


Following cutting on a #600 lap:

Pre-Polish with 3000 Diamond on BATT™  OR 8000 Diamond on Cast Zinc.

Polish:

  • QUARTZ with CeO or Chrome Oxide on DARKSIDE™ OR GREENWAY™
  • Everything from fluorite to sapphire with BATT™ 60K or 100K Diamond.

In addition, Beryls/Garnets are especially responsive to Chrome Oxide/Darkside™. Peridot and tourmalines are polished exceptionally well with Alumina on Darkside but have traditionally been done on BATT™ with diamond.
