Chuck & Faceplate Mounting

This lathe is shipped with the 3-jaw chuck installed. This is a scroll-type chuck, meaning that all three jaws move in unison when adjusted.

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 "0" 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 D-6 camlock mount. A chuck key is used to turn the locking cams (Figure 40) to secure/release the chuck/ faceplate.

Removing Chuck or Faceplate

1.DISCONNECT LATHE FROM POWER!

2.Lay a chuck cradle (see Figure 39) or plywood under the chuck or faceplate and over the bedway to protect the precision ground surfaces from damage and reduce injury if fingers get pinched.

3.One at a time, use the chuck key to turn each of the camlocks counterclockwise until the cam line aligns with the cam release datum line, as shown in Figure 40. As you turn the camlocks, they will rise up slightly from the spindle body.

4.Remove the chuck key, then use a dead- blow hammer or a wood block to lightly tap around the circumference of the chuck or faceplate to break it free from the spindle taper and camlock sockets. Be sure to support the bottom of the chuck.

5.With a rocking motion, carefully remove the chuck or faceplate from the spindle nose, as shown in Figure 41, making sure to support the weight with an adequate chuck cradle.
