ABSTRACT:
A fence (50) for supporting a workpiece, having two frame members (52, 54) and each frame member (52, 54) having rows of longitudinal grooves (62) in which frame elements or slide bars (66) are retained. An opening (24) between the frame members (52, 54) is reduced to a narrow gap to allow passage of a blade and varied according to a desired cutting angle by moving the slide bars (66) along the grooves (62). Movement of the slide bars (66) is achieved by rotation of a roller (75) mounted in a vertical bore in its respective frame member. The roller abuts the rear of the slide bars (66) and thus also prevents unwanted movement of the slide bars when stationary.
