Figure 22. Spur center properly embedded.
2. Using a wood mallet, tap the point of the spur
center into the center of the workpiece, so
that it leaves a center mark, then remove the
spur center.
3. Using a 1 ⁄
8
" drill bit, drill a 3 ⁄
16
" deep hole at the
center mark.
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 ⁄
4
", as shown in Figure 22.
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 quill handwheel to push the live cen-
ter 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.
9. Position the tool rest approximately 1 ⁄
4
" away
from the workpiece and approximately 1 ⁄
8
"
above the center line, as shown in Figure
23.
10. Test the setup by hand turning the workpiece
to make sure there is enough clearance all
the way around before starting.
Spindle Turning Tips:
• When turning the lathe ON, stand to the side
of the spinning direction until the lathe reach-
es full speed and you can verify that the lathe
will not throw the workpiece.
• Use the slowest speed when starting or stop-
ping the lathe, and when rough cutting.
• Select the right speed for the size of workpiece
you are turning. Use slower speeds for
large workpieces (4" diameter and over); use
the middle range speeds for medium sized
workpieces (2" to 4" diameter); and use faster
speeds for small sized workpieces (under 2"
in diameter).
• Keep the turning tool on the tool rest the
ENTIRE time that it is in contact with the
workpiece.
• Learn the correct techniques for each tool
you will use. If you are unsure, read books or
magazines about lathe techniques and seek
training from experienced users.
