Oneway 2137 Stronghold Chuck

The best and beefiest of Oneway’s scroll type chucks. This is the choice of world-class turners! Smooth one-hand setup and vibration-free running. Suitable for square or round work. Precision made with Carbon steel base jaws provide superior holding power.

If you create large bowls, vessels, and other specialty turnings, you’ll find this chuck to be a joy to use.  Made in Canada

With a massive 4-1/2″ diameter body, the Stronghold chuck is perfect for heavy turnings that require maximum stability and gripping power. It’s key-operated, so one-handed adjustments are simple and fast. A 5/1 ratio ensures solid holding power, while the patented over-extension prevention system ensures that the base jaws will never come loose during operation. A wide range of accessory jaws are available to cover all your turning requirements.

The Stronghold chuck is the largest chuck in the Oneway family, designed for lathes with a 16″ swing or greater. It weighs approximately 8 lbs (fully assembled with the No. 2 Jaws). It is considerably heavier than the Talon Chuck (3.5 lbs) or Oneway Chuck (4.5 lbs) which makes it perfect for large turnings.

Stronghold Basic Set: Includes the chuck body, #2 jaws, geared chuck key, 1-1/2″ jumbo woodworm screw, and T-handle hex key. The #2 jaws have an external (compression) chucking capacity of 1-3/4″ – 3-1/4″, and an internal (expansion) capacity of 2-3/8″ – 4″. Chuck weighs 8 lbs.

NOTE – Taper Lock Adapters are sold separately. Be sure to order the correct adapter needed for your lathe when buying a chuck.

NOTE – If your lathe has less than a 16″ swing, the Oneway Talon Chuck (#2985, sold separately) is recommended.
