chuck & faceplate
mounting
this lathe is shipped with the 3-jaw chuck installed.
this is a scroll-type chuck, meaning that all three
jaws move in unison when adjusted.
the 4-jaw chuck, on the other hand, features
independent jaws. this chuck is used for square
or unevenly-shaped stock.
if either chuck cannot hold your workpiece, the
cast-iron faceplate has slots for t-bolts that hold
standard or custom clamping hardware. With the
correct clamping hardware, this faceplate will hold
non-cylindrical parts such as castings.
the chucks and faceplate have a d-6 Camlock
mount. please note that there are lines stamped
into the cam and on the chuck body. A chuck key
is used to turn the locking cams (
figure 37) to
secure/unsecure the chuck/faceplate.

4. unlock the other cams in the same manner.
Make sure to support the chuck as you align
the last cam. the chuck may come off at this
point, so
it is important that the weight is
supported by an adequate chuck cradle.
5. remove the chuck key.
—if the chuck is still tight on the spindle,
tap the back of the chuck with a rubber or
wood mallet while supporting the bottom of
the chuck.
—if the chuck does not immediately come off,
rotate the spindle approximately 60˚ and
tap again. Make sure all the marks on the
cams and spindle are in proper alignment.
the chuck is heavy and is awkward to han-
dle. always protect the ways when remov-
ing or installing a chuck, and make sure
that you make a support cradle (figure 36).
use this cradle when installing or removing
chucks. ignoring this warning may lead to a
severe crushing or amputation injury!
