I have two of these and won't even use one all that often, so I'm selling one.
This device works like a scroll chuck with jaws that have pins to fit in the mounting holes in your soft jaws to hold your soft jaws out so that you can machine them (also can be used to true hard jaws).
Also sold by Dorian as the Tru-Jaws Chuck Adapter
