Minimizing vibration is key to making smooth cuts, particularly with thin or large workpieces. With this chuck, precise machining (total runout tolerance on the body is 0.0015") and careful design result in a work-holding system that significantly reduces chatter. The body is made of stainless steel, which not only resists corrosion from contact with green or acidic woods, but also permits machining to final tolerance without requiring an allowance for additional plating.
This manufacturing process provides a closer fit with the headstock mandrel, more stable support for the jaws and minimal lateral movement of the jaw slides, all of which help reduce vibration. Instead of using levers to operate the scroll, the chuck is key driven so you can apply significant clamping force with minimal effort. The scroll mechanism has a smooth action, is hardened for durability, and is enclosed to help reduce dust infiltration and frequency of maintenance. Radiused corners on the low-friction jaw slides help minimize risk of injury from contact with the spinning jaws.
The Evolution is a substantial chuck, suitable for lathes with swings of 12" and up. It is 114mm (4 1/2") in diameter, weighs just under 6 lb and accepts any Axminster jaw set. At just 50mm (2") thick, it has a low profile to reduce leverage on the headstock bearings when turning large pieces. The backplate has two rings for indexing, one with 24 divisions around the circumference and another with 36 divisions on the face.
The chuck is direct threaded and offered without jaws, giving you the option of selecting the initial set. Additional jaw slide sets are also available so you can interchange jaws without having to remove the mounting screws.
Produced in England, this is a comprehensive and well-made work-holding system.
