Abstract
A work piece holding device which includes a rectangular table top supported above the ground at a convenient work height and which has a fixed jaw at one end a facing sliding jaw which may be affixed to the table top at any point along the table either parallel to or at variable angles with the fixed jaw. Two inverted T-shaped slots in the table top provide guides for inverted bolts having parallel bolt head sides which firmly set the sliding jaw at the desired position and angular orientation. A variety of pairs of auxiliary jaw shapes for special jobs and a plurality of short screws placed along one of the jaws for applying resisting torque to one member of a particular pair of the auxiliary jaw shapes at one or more specific locations along that jaw are provided as well as an extender which provides for holding a work piece having a comparatively long dimension.
