figure 31. 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 the illustra-
tion in
figure 32 for details.
2. use a wood mallet to tap the point of the spur
center into the workpiece where the lines
intersect so that it leaves a center mark, then
remove the center. do this to both ends of the
workpiece.
3. use a 1 ⁄
4
" drill bit to make a 1 ⁄
4
" deep hole at
the center mark on the workpiece end that
will be mounted on the spindle spur center.
4. to help embed the spur center into the
workpiece, cut 1 ⁄
8
" deep saw kerfs into the
same workpiece end along the diagonal lines
marked in
Step 1.
5. if your workpiece is over 2" x 2", cut the cor-
ners off the workpiece length-wise to make
turning the corners safer and easier.
Spindle Turning
before beginning any turning operation
that uses the live center installed into the
tailstock quill, make sure the spur and
live centers are properly aligned (refer to
Aligning Centers on Page 33 for detailed
instructions). failure to head this warning
could result in the workpiece being thrown
from the lathe resulting in death or serious
personal injury.
