Mounting Workpiece Between
Centers
1. DISCONNECT LATHE FROM POWER!
2. Center drill both ends of the workpiece.
3. Install the MT#3 dead center in the spindle
with a lathe dog and faceplate, then install
the MT#2 dead center in the tailstock.
4. Generously lubricate the workpiece center
holes, then mount the workpiece on the
centers and hold it in place with light
pressure from the tailstock center.
5. Seat the center firmly into the quill by
rotating the tailstock handwheel clockwise
to apply pressure against the workpiece (see
the example photo in Figure 38).
Note: Only apply enough pressure with
the tailstock quill to securely mount
the workpiece between centers. Avoid
overtightening the center against the
workpiece, or the center may become difficult
to remove later, and the excess pressure
will result in unnecessary friction and heat,
which may damage the workpiece and
center.

between the centers.
Carriage & Slide Locks
The carriage, cross slide, and compound rest
can be locked into position to provide additional
rigidity during operation, especially during heavy
cuts.
To lock the carriage, use a 5mm hex wrench to
tighten the carriage lock cap screw shown in
Figure 39.
To lock the cross slide or compound rest, use an
8mm wrench to loosen the hex nuts and a 2.5mm
hex wrench to fully tighten the two end gib
adjustment set screws on both sides.
Note: When it is no longer necessary to lock
these components, make sure to loosen/re-adjust
the lock fasteners to allow the components to
freely move (see Figures 39–40).
