A precision miter gauge setting fixture system is described that includes a horizontal surface with a miter bar channel that bisects at least one pair of symmetrical arcs of angularly spaced, position receptacles drilled into the surface, where each angular position receptacle of a paired set of arcs, radially centers on a base position receptacle of the other symmetrically paired arc of angularly space, position receptacles. A pair of position posts, one snugly seated in the base position receptacle of one of the paired symmetrical arcs of angularly spaced, position receptacles, the other snugly seated in one of the angularly spaced, position receptacles of the other symmetrically paired arc define the desired angle for setting the angle of a miter fence head relative to the miter bar of a miter gauge received and sliding in the miter bar channel. The described precision miter gauge setting fixture system further includes one or more straight edged, accessory, detent step bars each having a length sufficient to span the radial distance between a base position receptacle of one of a pair of symmetrical arcs of angularly spaced, position receptacles and each of the angularly spaced, position receptacles of the other arc of the pair. Each straight edged, accessory, detent step bar also has one or more step detents, each detent incrementally increasing in depth, cut into one or both of its opposite longitudinal straight side edges proximate one or both of its ends for incrementally adding to and subtracting from the angle defined by the respectively seated, position posts, where the angle of the miter fence head of the miter gauge is determined by the angle of the longitudinal straight edge of the step dent bar opposite a particular step detent abutting against one or the other of the respectively seated position posts.
