Robert Sorby Eccentric Chuck

The Robert Sorby Eccentric Chuck is the most sophisticated chuck for multi-center turning.

Ease and accuracy of adjustment (without removing the workpiece from the chuck) is provided by the unique offset boss which accommodates the three different driving components on which to mount your workpieces, viz:-

1 - Screw chuck
2 - Ball drive and socket
3 - Faceplate

The Eccentric Chuck provides the means of driving from the head stock with or without tail stock support. The boss can be off-set incrementally by 1-1/4” (30mm) from zero datum point.

Screw chuck: The 25 x 10mm dia. parallel wood screw provides tremendous grip in either side-or end-grain. Requires an 8mm pilot hole.

Faceplate: an alternative method of attaching the work piece. Allowing the turner flexibility of approach. Ideal for larger work.

Hexagonal ball and socket drive: A unique system for driving between centers. The hexagonal ball and socket unit allows the work piece to be angled within 20 degrees of the lathe’s axis. Ideal for Cabriolet legs. The socket component is flanged and drilled for attaching to the work but can also be re positioned to index a variety of polygon sections. Allowing eccentric turning at one end of the work blending into concentricity at the other.

Unit comes standard with 1-1/2" x 6 TPI threads. Adapters to interface with other thread sizes are available separately.
