3-Jaw Chuck
Refer to Chuck & Faceplate Mounting
instructions on Page 27 to mount the 3-jaw
chuck to the spindle.
The 3-jaw scroll-type chuck included with this
lathe features hardened steel jaws that center the
workpiece. When the operator opens or closes the
jaws with the chuck key, the jaws move in unison.
There are two sets of removable hardened steel
jaws included with the 3-jaw chuck—inside and
outside jaws. Use the correct jaws for the size
and configuration of the workpiece to hold it
firmly and securely on the chuck (see Figure
49). The outside of the jaws are used to hold the
workpiece from the outer diameter.
Figure 49. Chuck and jaw selection.
Numbered from 1–3, the jaws must be used in
the matching numbered jaw guides, as shown in
Figure 50.
