Dividing Plate Set for 4" Rotary Table 

This dividing plate fits the 4" precision rotary table, PN 1810.

It consists of one plate with two sets of holes. One circle has 15 holes and the other has 28 holes. This lets you divide a circle into 1/3 degree increments.

Because this is 1/1080 of a circle, you can also divide a circle into any number of parts that can be divided evenly into 1080. You can divide a circle into the following number of divisions 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 24, 27, 28, 30, 32, 36, 40, 42, 45, 48, 54, 56, 60, 72, 84, 90, 96, 108, 120, 135,144, 180, 216, 270, 288, 360, 540, 1080.
