Claim:
A fence attachment apparatus for a power tool table equipped with an existing rip fence having a cutting-side lateral surface, an outside lateral surface, and a top fence surface, the fence attachment apparatus comprising: a longitudinal member with a longitudinal member top surface and comprising: a first side member having a top surface, a bottom surface, a cutting-side lateral surface, and a fence-side lateral surface; a second side member, substantially parallel to the first side member, having a fence-side lateral surface: and a bridge member connected to the first side member adjacent the top surface and extending along a major portion of the first side member, the bridge member having a top bridge surface with a width that extends a pre-defined distance transversely from the first side member to a distal side away from the fence-side lateral surface of the first side member, wherein the longitudinal member top surface includes at least one surface selected from the group consisting of the top surface of the first side member and the top bridge surface; wherein the longitudinal member substantially forms an inverted U-shape with a void to receive the existing rip fence, the fence-side lateral surfaces of the first and second side members respectively abut a major portion on the respective side of the existing rip fence and is adapted to be removably attached over the existing rip fence and the bridge member extending substantially horizontally over the top fence surface; a sliding member in sliding engagement with the longitudinal member top surface, the sliding member having a top sliding surface and a bottom sliding surface; and a slide mechanism disposed between the bottom sliding surface of the sliding member and the longitudinal member top surface, the slide mechanism enabling longitudinal movement of the sliding member relative to the longitudinal member.
