Abstract: A workpiece length measuring device for use in positioning a workpiece relative to a cutting tool (22) includes a guide rail (36) positioned transversely from the cutting tool (22). A fence assembly (20) is movable on the guide rail (36) and includes a pair of upstanding parallel guide plates (60, 62), these plates being longer in length than in height. A guide plate connector (64) is attached between the guide plates (60, 62) to maintain the plates in a parallel relation forming a channel therebetween to receive the guide rail (36) therein. The distance from the guide plate connector (64) to the ends of the guide plates (60, 62) remote from the guide plate connector is less than the height of the guide rail (36). A positioner angle (180) is mounted to and extends transversely from one of the guide plates (62) for positioning one end of a workpiece to be cut by the cutting tool (22).
