Spindle Turning - Grizzly G1067Z Instruction Manual

Spindle Turning

Before a workpiece is mounted into the lathe, the
points of the installed spur center and the live
center must align perfectly with one another
(Figure 22). View the alignment from above the
lathe and from the side.
Spur Center
Figure 22.
To mount a workpiece between centers:
1. Locate the center point on both ends of the
workpiece by carefully drawing diagonal
lines from corner to corner. The point of inter-
section is the center of the work. Find the
center of round wood stock by using a center
finder instrument.
2. When turning stock with a diameter greater
than 2", remove the corner length edges with
a hand plane or similar operation. DO NOT
attempt to "round" square stock in the lathe.
Serious personal injury many occur.
3. Hold the spindle vertically and support it on a
solid surface. Line up the spur center with
the center of the workpiece. Drive the spur
center into the stock about
blow hammer. Be careful not to split the
workpiece. See Figure 23. Wood with splits
along the grain may fly off during the opera-
tion. Note—With dense wood, drill a hole at
the center and score lines with a saw blade
for the spur center.

4. Once the spur center is firmly attached to the
workpiece, insert the spur center (with the
attached workpiece) into the headstock spin-
dle.
5. While supporting the workpiece, slide the
tailstock close to the end of the workpiece
and lock it into place.
Make sure the live center in the tailstock
lines up with the spur center in the head-
stock before turning anything between
centers. Failure to observe this step could
result in the workpiece being thrown from
the lathe. Serious personal injury may
occur.
6. Line up the live center with the workpiece
center. Turn the handwheel to press the
point of the live center into the workpiece.
Note—With dense wood, drill a hole at the
center and score lines with a saw blade for
the live center.
Do not press too firmly or the bearings will
bind and overheat. Likewise, do not adjust
too loosely or the workpiece will spin off
the lathe. Use good judgement. Serious
personal injury could result if care is not
taken.
7. Lock the tailstock in place.
