ABSTRACT:
A very accurate, multiple position, miter device or gauge for use with a table saw or the like includes a protractor having a plurality of equally spaced precision drilled step-holes, a sine bar, a micrometer adjust, and a guide bar adapted to fit within a guide groove or miter slot. In accordance with a particular example, the device includes a protractor having thirteen equally spaced, angled step-holes precisely spaced at 15.degree. from one another. The micrometer adjust includes a thimble screw having 1/6020 (one minute) increments with one full revolution of the thimble screw adjusting the angle of the sine bar by 1/40 (15 minutes). Also, the guide bar includes 0.degree., 3 3/4.degree. and 7 1/2.degree. offset threaded openings for receiving an angle hole lock shoulder bolt which passes through the protractor and into the guide bar. Hence, the miter device can be set at selected precise 15.degree., 7 1/2.degree. and 3 3/4.degree. increments using the angle step-holes, the 0.degree., 3 3/4.degree. or 7 1/2.degree. offset openings, and the angle hole lock shoulder bolt. Angles between the selected 15.degree., 7 1/2.degree., and 3 3/4.degree. increments are set precisely using the angle step-holes and offset openings together with the thimble screw. Once placed in the desired position, the sine bar is locked into position by a locking screw.
