figure 29. Jaw tightening sequence.
5. turn each jaw until it just makes contact with
the workpiece.
6. tighten each jaw in small increments. After
adjusting the first jaw, continue tightening in
opposing sequence (see
figures 28 & 29).
Check frequently to make sure you have not
wandered off your center point due to apply-
ing too much pressure to a single jaw.
8. Make fine adjustments by slightly loosening
one jaw and tightening the opposing jaw until
the workpiece is precisely aligned.
9. use low spindle speeds when machining
heavy eccentric workpieces.
faceplate
the faceplate is used to turn non-cylindrical parts
and for off-center turning.
to mount a workpiece on the faceplate:
1. disConneCt lAthe FroM poWer!
2. support the workpiece and slide the dead
center in the tailstock against the workpiece,
then lock the tailstock. For more information,
refer to the tailstock controls
on page 21 and
centers on page 27.
3. turn the tailstock quill so the dead center
applies enough pressure to the center point
of your workpiece to hold it in place.
4. lock the tailstock quill when sufficient pres-
sure is applied to hold the workpiece in place.
Additional support may be needed, depend-
ing on the workpiece.
securely clamp your
