ABSTRACT:
An adjustable stop mechanism for limiting the movement of a rip fence toward the cutting plane of a tiltable panel saw as an automatic function of the selected orientation of an abutment bar. The abutment bar has first and second orientations alternately presenting an abutment face of relatively low height, located at a greater distance from a reference surface, and a relatively greater height, located at a relatively shorter distance from the reference surface. When the abutment bar is rotated to the low height orientation, as to accommodate tilting of the panel saw blade, a limit stop position of movement of the abutment bar toward the cutting plane is automatically altered, so that the limit stop for the abutment bar support is farther away from the cutting plane. When the bar is oriented to present a full height abutment face, the limit stop automatically is altered in response to such orientation, to permit the support to move closer to the cutting plane.
