7. With the workpiece still attached, insert the
spur center into the spindle.
8. With the live center installed in the quill, draw
the quill back into the spindle as far as pos-
sible without forcing the center to release.
Note: This will give the quill and center the
greatest amount of support to safely hold the
workpiece during operation.
9. Loosen the tailstock lock lever, slide the
tailstock toward the workpiece until the live
center touches the workpiece centerpoint,
then lock the tailstock in this position.
10. use the quill handwheel to push the live
center into the workpiece at least a 1 ⁄
4
", then
tighten the quill lock lever to secure the cen-
ter and quill in place.
11. position the tool rest approximately 1 ⁄
4
" away
from the workpiece and approximately 1 ⁄
8
"
above the center line, as illustrated in figure
34.
12. test the setup by hand-turning the workpiece
to make sure there is enough clearance all
the way around before turning the lathe
ON.
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 correct speed for the size of
the workpiece you are turning. use slower
speeds for large workpieces (4" diameter and
over); use the middle range speeds for medi-
um sized workpieces (2"–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 approaching the
workpiece and is in contact with it.
• 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.

at least 1 ⁄

mark, as illustrated in figure 33.
Do not press the live center into the workpiece
too firmly or the center bearings will bind
and overheat. Likewise, do not press the
center too lightly or the workpiece could
come loose and spin off the lathe. Use good
judgement. Serious personal injury could
result if care is not taken in this procedure.
