Abstract: Apparatus for adjusting backlash out of a positioning assembly for shaft mounted ring useful in multiple rip saw machinery and for minimizing arbor length. A pair of axially oriented straps secured to the ring and positioned along the shaft for axially positioning the ring on the shaft wherein a radial pin carried by the ring is eccentrically rotatable in a mating aperture in one of the straps to adjust backlash between the straps and the ring out of the assembly when the pin is rotated. The saw hubs and respective saw adjusting collars are arranged in a semi-interleaved nesting relationship resulting in reduced arbor length.
