A bench-stop that can be quickly adaptedto every kind of work injury, provided sufficient care has beentaken to make the edge of the wedge andthe end of the slide pcrfccth square. By cutting down one end of the slideto a thickness of ^s inch and insertinga piece of ^-g-inch board between thewedge and the work, thin boards down to that thickness can beheld and planed.
