The drill chuck attaches to the spindle by means
of the arbor, shown in
Figure 14. Matched tapers
on the arbor and the inside of the chuck create a
semi-permanent assembly when properly joined.

To assemble the drill chuck and mount it to
the spindle:
1. Use mineral spirits to thoroughly clean the
drill chuck and arbor, and dry all surfaces
before assembly. Follow all safety warnings
on the container of mineral spirits.
Failure
to clean the mating surfaces may cause
the tapered fit to loosen during operation,
resulting in separation, which could lead
to serious injury.
2. Hand-turn the chuck to adjust the chuck jaws
until they are inside the drill chuck body.
3. Place the drill chuck face down on a
workbench. The arbor has a short taper and
a long taper. Place the short taper into the
socket in the back of the drill chuck and tap it
with a rubber or wooden mallet, as shown in
Figure 15. If the chuck fails to remain secure
on the arbor, repeat
Steps 1 & 2.

Drill Chuck & Arbor
DO NOT use a steel hammer on the drill
chuck to seat the arbor into the spindle.
You will damage the chuck or spindle,
which may make them unusable or unsafe.
4. Slide the arbor into the spindle while slowly
rotating the drill chuck. The flattened end
of the arbor (the tang, shown in
Figure 15)
will engage with a rectangular slot inside the
spindle.
5. Once the arbor has seated into the spindle
completely, tap the chuck with a rubber
mallet, as shown in
Figure 16.
