Rivelica OutLock 450 soft jaw machining adapter


Sep 22, 2005
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
UP TO 8" TJP47-3 CHUCK ADAPTER - DORIAN :: Tru-Jaws™ Chuck Adapters | Travers Tool

If you are thinking of joining the board just to buy it, forget it (yes, I have been pm'ed by people with zero posts asking to buy my stuff).
