Chuck & faceplate removal/installation
This lathe is shipped with a 3-jaw chuck installed, but some time you need to use a 4-jaw chuck or faceplate. The
chucks and faceplate mount to the spindle with a camlock system, which uses a key to loosen and tighten camlocks
for removal or installation
(see Figure 8).
Figure 8 Figure 9
Before the 4-jaw chuck and faceplate can be installed on the spindle, their respective cam studs must be installed and
adjusted. To maintain consistent removal and installation of the chucks and faceplate, each should have a timing mark
that can be lined up with a matching one on the spindle, so it will be installed in the same position every time
(see
Figure 9). Before removing the 3-jaw chuck, verify that a timing mark exists. If a mark cannot be found, stamp your
own on both the chuck and spindle.
Chuck & faceplate removal
1. Disconnect lathe from power!
2. Lay a chuck cradle
(see Figure 10) or a layer of plywood
over the bed ways to protect the precision ground surfaces
from damage and to prevent fingers from being pinched.
Figure 10
3. Loosen the cam-locks by turning the key counterclockwise
approximately one-third of a turn until the mark on the
cam-lock aligns with the single mark on the spindle nose in
Figure 11 . If the cam-lock stud does not freely release from the
cam-lock, wiggle the cam-lock until the cam-lock stud releases.
Note: These cam-locks may be very tight. A breaker bar may be
used to add leverage.
4. Using a dead blow hammer or other soft mallet, lightly tap
around the outer circumference of the chuck body to break the
chuck free from the cam-locks and from the spindle nose taper.
Caution: the chuck may come off at this point, so it is important you are ready to support its weight.
