Tailstock Controls
The tailstock comes supplied with a handwheel
with graduated dial, barrel lock, tailstock lock and
offset feature.
Figure 22 shows the locations of
each.
Tailstock Handwheel - Turning the handwheel
advances or retracts the barrel in the tailstock.
The graduated dial on the handwheel is
adjustable.
Barrel Lock Lever - This lever locks the tailstock
barrel in place.
Tailstock Lock Lever - This lever locks the tail-
stock in place on the lathe bed.
Offset Mechanism - Loosening these bolts
allows the tailstock to be offset from center by
turning a screw. This feature will allow taper turn-
ing when a workpiece is held between centers.

Cross Slide - This hand wheel moves the com-
pound slide across the lathe bed. Turning the dial
clockwise moves the slide away from the opera-
tor. The motion of this slide is used for facing a
workpiece and when advancing a cut for reducing
a diameter. The dial has 100 divisions with each
division representing 0.001" (one thousandths of
an inch) of motion for the slide. The label above
the dial reports that each line represents 0.002".
It is best to think of this as the amount of reduc-
tion in diameter on the part per line on the dial.
Therefore, rotating the dial 10 marks will move
the slide 0.010" and multiplying this amount by
0.002" equals 0.020". Therefore, the diameter of
the part will be reduced by 0.020".
Apron - The longitudinal motion of the apron is
controlled by the hand crank at the end of the
lathe bed.
See Figure 21 . The motion of this slide
is used when cutting along the length of a work-
piece. This slide can also be operated with the
power feed feature.

Graduated Dials - Each dial can be rotated with-
out turning the hand crank. This is helpful
because the dial can be set to zero after the tool
bit touches the part and the location of the slide
and tool bit will be known. The graduated dial can
be adjusted by holding the hand crank with one
hand and turning the dial with the other.
