Changing Jaw Set
The 3-jaw scroll chuck included with the lathe
features inside and outside hardened steel jaw
sets (see Figure below), which move in unison to
center a concentric workpiece.
When installing the jaws, it is important to
make sure they are installed correctly. Incorrect
installation will result in jaws that do not
converge evenly and are unable to securely clamp
a workpiece.
To change jaw set:
1. DISCONNECT LATHE FROM POWER!
2. Use appropriate device to protect ways (refer
to Installation & Removal Devices on
Page 29).
3. Insert chuck key and turn it
counterclockwise to back jaws out and
remove them individually in descending
order (i.e., 3, 2, 1).
4. Use mineral spirits to clean debris and grime
from jaws and chuck jaw guides.
5. Apply thin coat of NLGI #2 grease to
surfaces of removed jaw set. Store in safe
place free from moisture and abrasives.
6. Rotate chuck key clockwise until you see
tip of outer scroll-gear lead thread about to
enter a jaw guide (see below).
7. Insert jaw #1 into jaw guide and hold jaw
against scroll gear.
8.
Rotate chuck key clockwise one turn to
engage tip of scroll-gear lead thread into jaw.
Pull jaw; it should be locked into jaw guide.
9.
Install remaining jaws in numerical order,
in same manner. The jaws should converge
evenly at center of chuck.
— If jaws do not converge evenly, remove
them. Re-install jaws sequentially 1–3,
and make sure each one engages with
scroll-gear lead thread during its first
rotation.
Jaws are numbered from 1–3 (see Figure below).
The number is typically stamped on the side
or bottom. Jaws are designed to be installed
counterclockwise in numerical order in the jaw
guides, so they will hold a concentric workpiece
evenly.
