Dividing Plate Set for 4" Rotary Table
Part # 241-103
The dividing plate set is used to divide one 360° table rotation into divisions of 30'. The gear ratio of the rotary table is 1:72 so 72 rotations of the handwheel rotate the table one full rotation. The dividing plates have been provided with annular holes permitting required number of divisions of one handwheel rotation.
 
Dividing Plate Set for 6", 8" and 10" Rotary Table
Part # 241-101
The dividing plate accessory (241-101) is used to divide one 360° table rotation into 2-66 and all divisible by 2, 3, and 5 from 67-132 equal divisions. The gear ratio of the rotary table is 1:90 so 90 rotations of the handwheel rotate table one full rotation. Therefore for one full rotation of the table, the number of handwheel rotations per divisions "N" times the number of divisions "T" is equal to 90 rotations of the handwheel. So N x T= 90 or N = 90 ÷ T. The dividing chart ( page 4) was developed using this relationship.
For example if 17 divisions are required, then T=17, so N= 90/17 =55/17 = 5 10/34.

Each of the 17 divisions requires 5 full handwheel rotations and 10/34 of one handwheel rotation. The 10/34 of a handwheel rotation is obtained by using the dividing plates.

The dividing plates have been provided with annular holes permitting required number of divisions of one handwheel rotation.

There are 2 plates each with 2 faces for a total of 4 different faces with different hole combinations. In the example the plate with 34 holes drilled in a circle is required.

To obtain 17 divisions the handwheel is rotated 5 full rotations and 10 holes on the 34 hole circle for each division. The sector is used to make the 10 hole rotation quick and easy.
 
Dividing Plate Set for 16" Rotary Table
Part # 241-102
The dividing plate accessory (241-102) is used to divide one 360° table rotation into 2-66 and all divisible by 2, 3, and 5 from 67-132 equal divisions.
