ABSTRACT:
A workpiece guiding fence for a woodworking machine having a rotating vertical axis cutting tool comprises a fence support of hollow rectangular configuration defining a chamber which is connectable to a vacuum source for removal of dust and chips. A three part fence structure comprises a forward fence portion, a rearward fence portion, and an insert portion are adjustably positionable on the fence support. The insert portion is fabricated from a cuttable material and is moved into full engagement with the rotating cutting tool to provide a recess conforming to the configuration of the cutting tool. When a workpiece is guided along the aforedescribed three part fence, dust and chips produced by the cutting operation are withdrawn into the fence support by the vacuum source. Subsequent operations utilizing the same cutting tool permit the insert, which has been cut to conform to the configuration of such cutting tool, to be mounted on the fence and to effect the rapid, yet highly accurate, alignment of the three part fence with the specific cutting tool.
