Understanding Drill Press Spindles
- Tapered spindles: Most common type, using either Jacobs Taper (JT) or Morse Taper (MT).
- Jacobs Taper (JT): Available in sizes 0, 1, 2-Short, 2, 33, 3, 4, 5 and 6.
- Morse Taper (MT): Available in sizes 1 to 6.
- Threaded spindles: Less common, requiring a chuck with matching threads.
Installing the Drill Chuck
- Safety first: Disconnect the drill press from the power source.
- Remove old chuck (if necessary): Use a taper drift key to gently tap the chuck out of the spindle.
- Clean components: Thoroughly clean the chuck, arbor, and spindle with lacquer thinner or acetone.
- Assemble chuck and arbor: Insert the arbor into the back of the chuck and tap the arbor tang lightly to secure it.
- Insert into spindle: Align the arbor tang with the spindle slot and gently tap the chuck to seat it firmly.
- Check fit: Pull down on the chuck to ensure a secure fit.
Additional Tips
- Match the chuck's taper or thread to the spindle's specifications.
- Use a rubber-faced mallet to avoid damaging the chuck.
- Always clean the mating surfaces before assembly.
- If the chuck loosens during operation, stop and re-tighten it.
Note: Always refer to the specific instructions for your drill press model.
