Your chuck is designed to aid in holding wooden 

workpieces on your lathe, and is capable of gripping 

on both the outside and inside of various workpieces. 

EXTERNAL GRIP VS INTERNAL GRIP

The external grip is applied on the exterior of the 

workpiece, while the internal grip is applied on the 

interior of the workpiece. See Figures 1 & 2.

DOVETAIL JAWS

Your chuck has dovetailed jaws that are suitable for 

gripping a recess or tenon prepared in your work-

piece for clamping. Ensure that the recess or tenon 

prepared has a flat base so that it can rest flush 

against the flat surface of the chuck jaws. For the di-

mensions of your chuck’s dovetailed jaws, see Fig. 3.
