Mounting a Chuck or faceplate
1. disConnECt LAthE FroM poWEr!
2. Lay a piece of plywood on the bedway under-
neath the spindle to protect the precision
ground surfaces.
3. Clean away any debris and grime from the
mating threads of the spindle and chuck
or faceplate, then apply a thin coat of light
machine oil to the threads.
4. insert the longer chuck removal bar into the
spindle indent to hold the spindle still, then
thread the chuck or faceplate onto the spindle
and hand-tighten it, as shown in
figure 14.
Note: Overtightening the chuck or faceplate
onto the spindle will make removal difficult
and could damage the threads.
Make sure the chuck/face-
plate is firmly secured on
the spindle and remove
the chuck tools before
operation. Objects thrown
from the lathe could cause
serious personal injury or
death to the operator or
bystanders.
