63 mm 3-jaw self-centering chuck

This 63 mm three-jaw chuck centres round workpieces automatically for woodturning on a mini lathe. The self-centering action removes the need for independent jaw adjustment and speeds up repetitive set-ups. A mounting thread screw rod is included for direct attachment to the lathe spindle. It suits hobbyists and small-shop users who turn pens, handles or similar small-diameter stock.

Practical limits of the 63 mm capacity

The 63 mm body diameter restricts the maximum workpiece size that can be gripped externally. Internal gripping range is smaller still, so larger bowls or hollow forms cannot be held. The chuck provides one fixed mounting thread; lathes with a different spindle thread will need an adapter that is not supplied. Users needing greater capacity or multiple mounting options should consider a larger chuck system.
