To assemble the dividing plate attachment to the rotary table, remove handwheel (Ref.No.46). Bolt the required plate to the
collar using 4 screws (Figure 3, Ref No. 3). Slide the sector (Figure 3, Ref. No 4) over the worm shaft and eccentric sleeve
(Ref.Nos.31 and 37) with the sector screw exposed. Secure sector by sliding spring washer (Figure 3, Ref. No.5) against sector
and into slot in eccentric sleeve.
Slide crank arm (Figure 3, Ref.No.7) over flats at end of worm shaft and secure with spacer and nut ( Ref. Nos. 50 and 51) .
Spread the sector arms so that exactly 11 holes on the 34 hole circle are between the arms( see Figure 2). Tighten the sector
screw.
1.
Rotate the sector so that the sector arm is against the plunger assembly as in Figure 2A.
2.
Rotate the plunger assembly clockwise 5 full rotations and 10/34 of the a rotation by placing the plunger assembly against
the sector arm as in Figure 2B.
3.
Rotate sector clockwise so that first arm is against plunger assembly as in Figure 2C.
Repeat steps 1, 2 and 3 for each division. The dividing chart (Page 4) shows that for 19 divisions the plate with 38 holes is
required and each division needs 4 full rotation plus 28/38 of a rotation. The dividing chart shows that for 53 divisions, each
division requires 1 and 37/53 rotations, etc. For even divisions of 90 (2, 3, 4, 5, 6, 9, 10, 15, 18, 30 and 45) simply rotate the
crank arm required number of full turns using the same hole on any plate.
Maintenance
Refer to Figure 4 thru 8.
Worm
Shaft
Adjustment
To adjust for wear in the worm shaft, the lock nut ( Ref.No.35) must be adjusted.
Remove handwheel (Ref No. 46) and spacer (Ref No. 36) Tighten locknut until play is removed from engaged worm shaft and
clamping surface. Do not over‐tighten locknut. Replace spacer and handwheel.
Eccentric
Sleeve
limit
screw
adjustment
The threaded pin (Ref No 29) regulates the rotation at eccentric sleeve. If the worm shaft does not engage table properly when
vernier collar is rotated counterclockwise, then unscrew set screw ( Ref No, 28) and adjust the threaded pin until proper
engagement is achieved.
Note: For model 221‐308set screw ( Ref No. 28) and threaded pin (Ref No.29) is located in lower right corner of the bottom of
the base casting (Ref No. 1)
