that it leaves a center mark, then remove the
spur center.
4. Using a
1
/8" 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.)

2" x 2" to make turning safer and easier.

the live center touches the workpiece center

Do not press the workpiece too firmly with
the tailstock or the bearing will bind and
