<p>The vise system (9) has a bracket section (13) which can be secured to any flat horizontal work surface, particularly a drill press platen (11), with sliding and rotating degrees of freedom with respect to a bracket bolt (16). The bracket bolt (16) threads into a hole in the work surface and can tighten down to rigidly hold the bracket section (13) in position. A vise section (10), capable of clamping a work piece between fixed and movable jaws, is connected to the bracket section by a horizontally-oriented connecting bolt (30), about which the vise section can rotate, and which can be tightened to secure the vise section at any selected angle. The vise section has a rectangular cross-section, facilitating rapid self-indexing of angles 0, 90, 180, and 270 degrees with respect to the bracket section. The vise system (9) is capable of being pivoted to a position in which the vise section extends beyond the edge of the work surface in order to accommodate work pieces in orientations which would otherwise interfere with the work surface. The vise system (9) can be removed from or attached to a variety of work surfaces by loosening the bracket bolt (16) without removing it from the surface, and with the vise section (10) still clamping a work piece.</p> |
