<p>A work bench (10) has a stationary planar upper surface (21) and a fence (20) to which a piece of work (161) is clamped. The fence (20) may be moved so that the position of the work piece (161) may be adjusted. Once in the desired position, the work piece remains immovable. A carriage (90) slides beneath the upper surface (21) and a router (91) is mounted on the carriage (90). The router bit (22) extends through an elongated slot (24) in the upper surface (21) and into contact with the immovable work piece (161). As the carriage (90) slides the router cuts the work piece (161). The fence (20) has a base (26) which rotates on top of the upper surface (21) and a bracket (42) slides on rails (44) formed on top of the base. Knobs (41, 58, 59) are provided for tightening the base (26) to the upper surface (21) and the bracket (42) to the base (26) to prevent such rotation and sliding.</p> |
