4.2.6 INSTALL THE SPUR CENTER
Insert the spur center into the headstock spindle. The
spur center (A) has a No. 2 Morse Taper shank, that
matches the taper on the inside of the headstock spindle
for a secure, friction fit. FIG. 4.2.6
If replacing the spur center, or purchasing new centers,
make sure that the item is machined with a No. 2 Morse
Taper shank.
4.2.7 THE KNOCKOUT BAR
4.2.8 INSTALL THE LIVE CENTER
The knockout bar (B) is used to remove the spur center
from the headstock spindle.
Insert the knockout bar into the spindle hole at opposite
side from spur center. The knockout bar is then used to
hit the back end of the spur center to release it from the
spindle. Carefully hold the spur center as it is knocked
out of the spindle, so that it does not fly out and get
damaged, or injure your hand. FIG. 4.2.7
- Insert the live center (C) into the tailstock spindle. This
center also has a No. 2 Morse Taper shank. FIG. 4.2.7.
- The knockout bar (B) can also be used to release the
live center from the tailstock. FIG. 4.2.8.
To remove live center from the tailstock spindle, loosen
the tailstock’s spindle locking lever and rotate the hand
wheel counterclockwise to retract spindle into the body of
the tailstock. The live center will automatically be pushed
out of the spindle. Carefully hold the live center as it is
pushed out of the spindle, so that it does not fall out and
get damaged, or injure your hand.

5. ADJUSTMENTS AND OPERATIONS
5.1 ADJUSTING THE TOOL REST
- The tool rest base can be easily moved along the lathe
bed to position it along the length of your work piece, and
also adjusted in or out to set the tool rest close to the
work for turning. Loosen the tool rest base locking lever
counterclockwise, slide tool rest base to a new position,
and then re-tighten the base’s locking lever, clockwise.
- To adjust the height of the tool rest, loosen the tool rest
locking lever, raise or lower tool rest, then re-tighten the
rest’s locking lever. FIG. 5.1.
Fig.5.1
CAUTION
- Position the tool rest as close to the work piece as possible. It should be 1/8” above the center line of the work piece.
- To adjust the clamping action of the tool rest base, or the tailstock, adjust the locking nut - turn it clockwise to tighten,
and counterclockwise to loosen. See FIG. 4.2.2 .
