ABSTRACT:
A vise having a fixed jaw on a body which has a base secured to a work surface and may be rotated through 180.degree.. The body has a guide slot formed therein and a movable jaw is slidably received in the guide slot. A guide rod is disposed through an opening in the movable jaw and is threadably received in an upright lug secured to the base for movement of the movable jaw. A positioning nut is keyed to the threaded guide rod and secures the movable jaw to the guide rod. The vise has clamp claws on the inner and outer sides of the fixed and movable jaws so that the vise can exert force in both directions. The workpiece may be clamped between the inner side of the jaws and the jaws may be adjustably disposed within the workpiece to secure the workpiece about the outer side of the jaws. The end of the movable jaw which extends through the body has a notched slot therein and there is also a notched recess in the body of the vise. A workpiece may be disposed vertically in the notched slot and clamped against the notched recess in the body.
