Replacement jaws and the most up-to-date instruction manuals can be found on wenproducts.com.
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 workpiece
for clamping. Ensure that the recess or tenon pre-
pared has a flat base so that it can rest flush against
the flat surface of the chuck jaws. For the dimensions
of your chuck’s dovetailed jaws, see Fig. 3.
