Model T10811 Wood Lathe Chuck Set
-7-
Step Jaws
The step jaws have two outside profiles of differ-
ent circumferences designed to expand into the
recess cut into the workpiece. The surfaces of the
jaws have ridges that push into the wood which
increases the gripping power.
The center surfaces of the step jaws are ridged
and can grip a dowel-type workpiece from the
outside that is fed through the chuck and spindle
bore.
Basically, step jaws combine the capabilities of
the round jaws and the pin jaws, but are much
more versatile than either of those jaws alone.

Flat Jaws (or Cole Jaws)
Used with included grip studs, flat jaws are pri-
marily used to finish the bottom of a bowl-type
workpiece (see examples below). The included
studs are 13 and 18mm in height and are rubber
coated to prevent marring. Use the stud set and
configuration that has the most surface contact
with the workpiece.
