Abstract
A vise stop for positioning a workpiece in a vise includes a crossbar having a first end, a second end and a mounting surface. The crossbar is attachable to the vise and a first stop arm is pivotally connected to the crossbar first end for positioning a workpiece along an X axis. In the preferred embodiment of the invention, a second stop arm is pivotally connected to the crossbar second end. A friction disc is compressively disposed between an inner face of both the first and second stop arms and the first and second ends of the crossbar. The friction disc allows the stop arm to be frictionally positionable and rotatable about its point of attachment to the crossbar end. The friction disc may be configured as a fiber washer, a spring washer or a compressible o-ring.
