Eccentric Chuck
The Robert Sorby Eccentric Chuck is the most
sophisticated chuck for multi-centre 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 - Screwchuck
2 - Ball drive and socket
3 - Faceplate
Turning a goblet with off-set stem using
0, 10 and 20mm settings.
The Eccentric Chuck provides the means of
driving from the headstock with or without
tailstock support. The boss can be off-set
incrementally by 1 1 ⁄ 4 " (30mm) from zero datum point.

pilot hole. An alternative method
of attaching the work

turner flexibility of
approach. Ideal for
larger work. A unique system for driving between centres.
The hexagonal ball and socket unit allows the
work piece to be angled within 20˚ of the
lathe’s axis. Ideal for Cabriole legs. The socket
component is flanged and drilled for attaching
to the work but can also be repositioned to
index a variety of polygon sections. Allowing
eccentric turning at one end of the work
blending into concentricity at the other.

Please specify when ordering, make of lathe
and thread size of spindle .

The Eccentric Chuck comes complete with a
comprehensive 12-page instruction manual,
interactive DVD and project book. It also
includes a threaded adaptor to make it
compatible with your lathe.
The Eccentric Chuck is featured in our
Decorative Techniques DVD (RSDVDDT) and
the Thread Cutting and Eccentric ChuckDVD
( RSDVDTCEC).
Stebcentre
The original Stebcentre is an invaluable
accessory for every woodturner. Fitted in the
lathe head-stock it is a boon for both the
novice and the experienced.
Its ring of sharp teeth ensure that the
Stebcentre bites the wood to give more
security and more drive. Because there are
several points of contact there is minimal risk
of splitting. The Stebcentre can be used with
equal confidence on both soft and hardwoods
as well as synthetic materials.
In its patented design the Stebcentre also
features a spring-loaded point. By slightly
backing off the tail-stock the work piece still
remains resting between the revolving centre
and the Stebcentre. This allows the turner to
inspect his work without the need to switch off
the lathe. Where time is a critical factor the
Stebcentre is ideal as the work-piece can be
quickly removed without stopping the lathe.
Overall length: 4".

The original concept has subsequently
developed in two directions. The first of these
is the Steb Drive which has been adapted to
fit into most popular 4-jaw lathe
chucks. This saves the need d
to remove the chuck every
time the turner wants to
use his Stebcentre.
Secondly, largely inspired by Norwegian turner
Petter Herud a series of Revolving (or Live)
Stebcentres has been introduced. Not only do
these offer the same degree of security as the
conventional Stebcentre, but they have allowed
the turner to experiment with basic off-centre
turning.
