Inexpensive 4-Jaw Chuck For Metal or Wood Lathes

Harbor Freight Company <http://www.harborfreight.com> in the US sells a 4-Jaw chuck for their wood lathe (Part Number: 31223). This unit can be adapted for use on various metal turning lathes. The center hole is 3/4 inch, 10 TPI, so a 3/4" bolt with coarse threads can be clamped into smaller or 3-jawed chucks on metal lathes and used to mount this larger 4-jawed chuck. This actually works fairly well for less critical tasks.

For more critical use you would probably want to build an adapter plate so this could be directly mounted as a replacement for existing 3-jaw chucks.

The jaws are adjusted independently, and can be reversed for gripping larger or smaller turnings.
