Chuck & Faceplate
Mounting

This lathe ships with the 3-jaw chuck installed.
This is a scroll-type chuck where all three jaws
move in unison when the chuck key is used.

The included 4-jaw chuck features independent
jaws, which are used for square or unevenly-
shaped stock, and to mount work that needs to
be adjusted to near zero total indicated runout.

If neither chuck can 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.

The chucks and faceplate have a D1-6 camlock
mount. A chuck key is used to turn the locking
cams to secure these devices to the spindle.

Installation & Removal
Devices

Because chucks are heavy and often awkward to
hold, some kind of lifting, support, or protective
device should be used during installation or
removal. The weight and size of the chuck will
determine the appropriate device to use (refer to
the following figure for examples).

Figure 36. Examples of common devices used during

chuck installation and removal.

A dropped chuck can cause amputation,
serious crushing injuries, or property damage.
Always use a lifting, support, or protective
device to reduce this risk when installing or
removing a chuck.

This lathe is equipped with a D1-type spindle
nose. This type of spindle uses camlocks to
securely mount a chuck or faceplate with
repeatable precision and ease.

Never use spindle speeds faster than the
chuck RPM rating or the safe limits of your
workpiece. Excessive spindle speeds greatly
increase the risk of the workpiece or chuck
being thrown from the machine with deadly
force!
