Clamping Lever (C): Lift up to lock. Push down
to unlock. If the tailstock is under heavy load,
tighten the eccentric shaft (D) at the back of the
tailstock for auxiliary locking.
NOTE: If the tailstock refuses to lock, do the
following:
1. Move handle to unlocked position.
2. Slide the tailstock to an area that allows
access to the underside of the tailstock. You
may need to remove the stop pin (G) to do
this.
3. Tighten tailstock clamping bolt (underside of
tailstock) 1/4 turn. Test for proper locking.
Repeat as necessary.
4. Re-install stop pin.
Off-Set Adjustment :
Refer to Figures 13 and 14.
Follow this procedure to off-set the tailstock to
cut shallow tapers:
1. Lock tailstock in position with the clamping
lever (C).
2. Loosen eccentric shaft (D) at back of
tailstock.
3. Two hex socket cap screws are located at
the base on either side of the tailstock (E,
Figure 12 shows the one in front). Loosen
one of these while tightening the other.
Gibs : To take up any play in the tailstock,
tighten the two gib screws (F) on either side of
the tailstock base. CAUTION: Do not over-
tighten, as excessive tightening will lead to
premature wear of the gibs and mating parts.
Aligning Tailstock to Headstock
Before proceeding, headstock alignment should
be verified. See “Headstock Alignment”.
1. Fit a 12” ground steel bar between centers
of the headstock and tailstock (Figure 15).
2. Fit a dial indicator to the tool post and
traverse the center line of the bar.
3. If tailstock adjustment is needed, alternately
loosen and tighten front and rear hex socket
cap screws (E, Figure 13).
