Chuck and Faceplate

Mounting

The three-jaw scroll chuck has hardened steel jaws that

self-center the workpiece. An extra set of jaws is included

for machining larger workpieces.

The four-jaw chuck also has hardened steel jaws but are

adjusted independently to hold an off-center workpiece.

Each jaw can be removed from the chuck body and

reversed for special clamping applications.

The cast-iron faceplate has slots for T-bolts that hold

clamping fixtures. This face plate and aftermarket

clamping hardware will hold non-cylindrical parts such as

castings for many types of turning operations.

Both chucks and the faceplate are removed and installed

the same way.

To remove and install the chuck or face plate, do these

steps:

1. DISCONNECT POWER TO THE LATHE!

2. Lay a piece of plywood over the bedways to protect

the precision-ground bedways.

3. Use a 2mm hex wrench and loosen the two chuck

retaining set screws shown in Figure 11.

4. Use spindle and chuck levers to loosen the chuck

from the spindle as shown in Figure 12.

Note: The chuck and spindle are right-hand thread.

5. Support the chuck, and while anticipating its weight,

unscrew the chuck counterclockwise and set it aside.

6. Clean the threads on the spindle and the new chuck

or faceplate with a clean rag and oil the threads.

7. Thread the chuck or faceplate onto the spindle and

tighten in place with the levers.

8. Tighten the two setscrews.
