SPUR AND LIVE CENTERS
To reduce the risk of injury, tighten all
screws and levers securely when adjusting any part
of the lathe.
To reduce the risk of injury, be sure
the taper on the spur center (G) is clean before
mounting to the headstock spindle.
The spur center (G) Fig. 5 and live center (F) can be
used together (as shown in Fig. 5) to turn workpieces up
to 16-1/2" (419 mm) in length.
ATTACHING SPUR CENTER
Drive spur center into the workpiece using a soft mallet.
Then fit spur center (G) Fig. 6 into the headstock spindle
bore (N) snugly.
NOTE:
You do not need to remove the faceplate to attach
spur center.
REMOVING THE SPUR CENTER
To reduce the risk of injury, when
removing the centers, use a soft cloth to protect
against the sharp edge.
Insert knockout bar (H) Fig. 7 into spindle bore (as
shown in Fig. 7) and tap spur center (G) firmly to remove.
If necessary, tap knockout bar firmly with soft mallet.
NOTE:
To avoid damage to spur center, be sure to hold
onto spur center as you tap it out.
ATTACHING LIVE CENTER
Loosen tailstock quill locking screw (O) Fig. 8. Turn
tailstock crank (P) clockwise three full turns to advance
the quill (Q). Then fit the live center (F) Fig. 9 into the quill
snugly. The tailstock quill locking screw (O) Fig. 8 will be
tightened after you mount the workpiece.
REMOVING THE LIVE CENTER
To reduce the risk of injury, when
removing the centers, use a soft cloth to protect
against the sharp edge.
To eject the live center (F) Fig. 9, turn tailstock crank
(P) Fig. 8 counterclockwise to retract the quill. As quill
retracts, the live center contacts an internal ejecting pin.
When it does, you will feel the crank get harder to turn.
Turning further past this point loosens the live center for
easy removal.
