center drill close to the work and lock in position. Turn the tailstock handwheel to bring
the center drill forward. After the hole is started with the center drill, switch to a standard
drill bit of the desired size to drill the hole.
Headstock Drilling
The drill chuck comes fitted with a #0 Morse arbor that fits in the tailstock spindle. To
use it in the headstock you will need to first change to the #1 Morse arbor which is
included with your lathe. To change arbors, put the drill chuck key in its hole to give you
better purchase to grip the chuck while using a wrench to remove the #0 arbor and
replace it with the larger #1 arbor. Put the drill chuck in the headstock. Then put the
drawbolt with its washer through the spindle hole from the other end of the headstock and
tighten the drawbolt. DO NOT OVERTIGHTEN! (To remove, loosen the drawbolt a
little and give it a light tap with a plastic mallet to break the chuck loose from the taper
before completely removing the drawbolt.)

The easiest way to center drill the end of a round shaft which has a diameter too large to
be put through the spindle is to support it with a steady rest (P/N 1074) while the end is
being drilled. If this isn't possible, find the center with a centering square, prick punch a
mark and center drill by hand. (See accessories, page 16. See also our Tools and
Accessories Catalog for a photo of the steady rest in use.)
Reaming
Twist drills will generally not drill perfectly accurate sizes, and very small boring tools
are not satisfactory in deep holes because of their flexibility. Therefore, reaming is used
for holes requiring accuracy within .0005" (.013mm). Reamers are available in any
standard size but are rather expensive and are generally not purchased to do one-of-a-
