Dividing Plate
Set for 4" Rotary Table Part # 241103 

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 # 241101 

The dividing plate accessory (241101) is used to divide one 360°
table rotation into 266 and all divisible by 2, 3, and 5 from 67132
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 # 241102 

The dividing plate accessory (241102) is used to divide one 360°
table rotation into 266 and all divisible by 2, 3, and 5 from 67132
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
