3. 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.
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.)
5. Cut the corners off your workpiece if it is over
2" x 2" to make turning safer and easier.
6. Drive the spur center into the center of the
workpiece with a wood mallet as shown in
Figure 12.

7. Insert the drill adapter into the drill chuck and
tighten firmly.
8. With the workpiece still attached, screw the
spur center onto the drill adapter.
9. Slide the tailstock toward the workpiece until
the live center touches the workpiece center-
point, then tighten the tailstock hex bolt.
Do not press the workpiece too firmly with
the tailstock or the bearing 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.
