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.
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 29. 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 that are 
adjusted with a chuck key 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!
