Figure 23. Typical spindle turning operation.
To set up a spindle turning operation:
1. Mark both ends of your workpiece by draw-
ing diagonal lines from corner to corner. The
intersection point of these lines will show you
the center of your workpiece. See
Figure 24
for details.

2.
Using a wood mallet, tap the point of the spur
center into the center of the workpiece, so it
leaves a center mark, then remove the spur
center.
3. Using a
1
⁄
4
" drill bit, drill a
1
⁄
4
" deep hole at the
center mark. (Additionally, if the end of your
workpiece is square, cut
1
⁄
8
" deep saw kerfs
across the corners to help embed the spur
center.)
4. Cut the corners off your workpiece if it is over
2" x 2" to make turning safer and easier.
5.
Drive the spur center into the center of the
workpiece with a wood mallet to embed it at
least
1
⁄

", as shown in
Figure 25
.
6.
With the workpiece still attached, insert the
spur center into the headstock spindle.
7. With the live center installed in the tailstock,
slide the tailstock toward the workpiece until
the live center touches the workpiece center-
point, then lock the tailstock in this position.
8.
Use the tailstock adjustment knob to push the
live center into the workpiece at least a
1
⁄
4
".
Do not press the workpiece too firmly with
the tailstock or the bearings will bind and
overheat. Likewise, do not adjust too loose-
ly or the workpiece will spin off the lathe.
Use good judgement. Serious personal
injury could result if care is not taken.
