Chuck & Faceplate
Mounting
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 chuck
RPM rating or safe limits of your workpiece.
Excessive spindle speeds greatly increase
risk of workpiece or chuck being thrown
from machine with deadly force!
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.
The included faceplate has slots for T-bolts that
hold standard or custom clamping hardware. With
the correct clamping hardware, a faceplate offers
a wide range of uses, including machining non-
concentric workpieces, straight turning between
centers, off-center turning, and boring.

Camlock Stud
Installation
Follow this procedure to install camlock studs in
chucks, faceplates, or drive plates so they can be
mounted to the spindle.
Note: Skip this section if camlock studs are
already installed.
To install camlock studs:
1.
Lightly oil threads of each stud.
2.
Thread studs until datum line is flush with (or
just above) surface and alignment groove is
positioned over hole.

3.
Install a cap screw in hole next to each stud.
These cap screws prevent studs from rotat-
ing so they properly engage with camlock
during installation.
Note: It is normal for studs to have a small
amount of play or looseness after installing
and tightening the cap screws.
