Innovative coil-spring chuck design was invented in 1972 and is no
longer being manufactured, as far as we can tell. The one for sale here
was purchased in 1975, used for 25 years, and has another 50 years of
useful life in it.
Workpiece is started as a spindle turning, and
a flanged disk is turned at the bottom. This disk is inserted into
the chuck, which is tightened around the wooden flange, causing the spring
to contract and producing a solid grip
that holds large pieces safely. Includes wooden hand sanding jig for disks
available separately.
PRICE: to be determined - or make an offer!

Workpiece, jig, or custom wooden faceplate is made as part of a spindle
turning. Tightening the chuck draws spring inward to grip firmly.
This wooden fixture is used for rapid mount/dismount of toy wheels
to hand sand rough edge. Center pin locates workpiece, steel dog
provides rotation. Workpiece is held in place by gentle finger pressure.
