Arbor Removal

The arbor can be removed to install other Morse taper tooling in the spindle. A drift key is included to help remove the arbor or other tooling from the spindle. Usually, once the chuck and arbor have been properly mounted together, they are considered semi-permanent connections. (If you would like to install a different chuck, we recommend obtaining a new arbor for that chuck.)

To remove the drill chuck and arbor:

1.UNPLUG THE DRILL PRESS!

2.Rotate the downfeed handles until the drift key slot is exposed in the side of the quill.

3.Tighten the return height nut, shown on Page 25, up against the depth stop bracket. This will prevent the quill from retracting when you release the downfeed handles.

4.Rotate the spindle until the inner drift key slot is aligned with the outer slot, as shown in Figure 18. You will see through the spindle when the slot is properly aligned.

5.Insert the drift key into the drift key slot, and allow the quill to rise and trap the drift key by backing off the downfeed handles slightly.

6.Hold the drill chuck with one hand and tap on the drift key with a rubber or wooden mallet (Figure 18) until the arbor releases.

7. While holding onto a downfeed handle, loosen the return height nut so that the quill can retract completely.

8.Carefully retract the quill into the headstock.
