Chuck and Drill Sizes

The size of the chuck indicates the largest size drill shank it
will hold. Larger chucks will hold larger drills, but they are
also longer and eat up more of the space you have between
centers on your lathe. Not only is a larger chuck longer, but
the drill bits also get longer as they get larger. On the mill
or on the Model 4400/4410 long bed lathe this is usually
not a problem, but on the Model 4000/4100 lathe, unless
you need to hold a large diameter drill, you will probably
want to use the 1/4" or 5/32" drill chucks because of their
shorter overall length.
The 5/32" 0JT* chuck is offered in two versions. P/N 1010
is fitted with a #1 Morse arbor to be used in the headstock
for drilling on the mill or lathe. Included with this chuck
is a drawbolt and washer. P/N 1015 is fitted with a #0
Morse arbor for use in the tailstock. The 1/4" (P/N 1072)
and 3/8" (P/N 1069) chucks come with both a #0 and #1
Morse arbor which can be interchanged so the chucks can
be used in either the headstock or tailstock. The 1/4" and
3/8" chucks will hold drills as small as 3/32". For using
smaller drills down to 1/32" or even smaller the 5/32" chuck
is recommended.
* The designation "0JT" stands for "Zero Jacobs Taper".
The chucks come with a zero Jacobs tapered hole in the
back. Sherline installs an arbor to fit either the #1 Morse
or #0 Morse tapers in the headstock and tailstock. These
arbors are pressed into the zero Jacobs taper which is why
they are not as easily interchangeable as are the arbors for
the 1/4" and 3/8" chucks which thread onto the back of
the chucks.

Purpose of the Tailstock Chuck

The tailstock chuck is one of the most important accessories
you will need for your lathe. It will enable you to accurately
drill, ream or tap any part mounted in the lathe. The part to
be machined is chuck or collet mounted in the headstock.
The tool is held in the tailstock chuck and fed into the part
using the tailstock ram feed. Parts that are going to be
mounted between centers can be center drilled this way.
Other parts requiring a hole accurately drilled on center
such as a shaft, pulley sheave or gear blank will also be
done this way.
