Operation: Rotary Table
Refer to Figures 4 thru 8.
1.
Always rotate handwheel (Ref.No.46) clockwise. This will eliminate any backlash in the worm gear. If handwheel is
rotated past desired position, rotate handwheel one full turn counterclockwise and then rotate handwheel clockwise to
desired position.
2. The worm shaft (Ref. No.31) can be disengaged from the table (Ref. No 2) so that operator can rotate table by hand.
Loosen handle (Ref. No. 25) by turning it counterclockwise, loosen handle (Ref. No 39) and turn vernier collar (Ref. No
40) clockwise until it is snug. Table can now be rotated by hand. To engage worm shaft, turn back vernier collar. Secure
handle ( Ref. No. 25)
3. Table is locked into position by rotating clamp handles ( Ref.No. 7) clockwise until snug. Turn handles counterclockwise to
free table. Turning the handle (Ref. No. 47) after loosening handle (Ref.No. 39) rotates the table.
4. The table is provided with a scale to indicate the angle of rotation. The indicator (Ref.No. 22) can be used to verify the
angle of rotation on scale. The indicator can be adjusted by loosening the knob (Ref.No.23) and moving the indicator along
the slot. Secure knob after completing adjustment.
5. The center sleeve has been ground to a Morse Taper. Centers with a Morse Taper shank can be mounted to the rotary
table for precision centering and measuring operations. (see dimensions in Fig. 1 for MT of ea. table.)
6. The gear ratio of the rotary table is 1:90 so that 90 rotations of the handwheel rotate exactly one full rotation. One rotation
of the handwheel is equal to 4

rotation of the table. The micro collar is graduated into one minute increments.
7. A vernier scale is provided on the vernier collar (Ref. No. 40) for measurement of angle rotation to an accuracy of ten
seconds.
8. Read the degrees and minutes from the micro collar and use the vernier collar scale to read ten seconds.
Dividing Plate Accessory
Refer to Figures 2, 3, and 4, 5, or 6
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

.
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.
