[57] ABSTRACT
tioning the rip fence a precise distance from the saw blade for accurately cutting a workpiece. The precision rip fence alignment gauge comprises first and second symmetrical laterally separable gauge half assemblies. Each gauge half assembly comprises an elongated flat rod with an elongated miter slot engagable locator bar slidably connected transversely thereto such that the elongated flat rod is longitudinally displaceable relative the locator bar. The elongated flat rod is constrained to an accurate 90° angle relative the locator bar with an alignment plate fixedly connected to the locator bar and slidably contacting an edge of the rod. A threaded stud projects upwardly from near an end of the locator bar and extends through a longitudinal slot through the elongated flat rod for slidably holding the edge of the rod in contact with the alignment plate. A thumbnut threadedly engages the threaded stud for locking the rod longitudinally relative the transverse locator bar. A pair of spaced apart alignment pins extends from one edge of one of the elongated bars. The pins are mateable with a corresponding pair of holes extending into the facing edge of the juxtaposed other longitudinal bar whereby the ends of the bars are aligned flush with each other. Measuring indicia may be printed on at lease one of the elongated rods.
In a table saw having a rip fence and a miter slot, a new precision rip fence alignment gauge for quickly posi
