Index Gears

$74.00 – $205.00

The Ultra Tec Mast comes with a 96 Index Gear–the most often used.  Faceting designs specify the Index Gear, and the 96 and 64 cover about 80% of published designs.  Changing Index Gears takes only a few minutes.  The symmetry of a design depends on which numbers divide evenly into the available number of teeth on the Index Gear.  For example, a 5-sided design will use an 80 Index Gear, a 3-sided design will use a 72 or 96, etc.  Why does a designer choose one or another when both will allow the same number of sides?–well, the more teeth, the more subtlety of design is possible.

Index Gears available are:
32 – 64 – 72 – 77 – 80 – 84 – 96 – 120
