The Delta Auto Set Miter Gage Model No. 864 was a standard accessory item that came with Delta table saws including the 10″ Unisaw, 10″ Contractor’s Saw, 9″ Bench Model Tilting Arbor Bench Saw, 8″ Tilting Arbor Table Saw, 8″ Tilting Table Circular Saw, and the 10″ Tilting Table Circular Saw.

The miter gage also can be used in the grooves provided on Delta 14″ band saws, and the 6″ by 48″ belt and 12″ disc sanders and the combination belt and disc sander. It also fits the Delta light and heavy duty shapers.

The miter gage has a 7 inch face and a 3/8″ x 3/4″ x 18″ bar which fits the table slot of circular saws and other machines. It can be set at any angle up to 60 degrees to the right or left, and it has adjustable stops for instantaneous settings at zero and 45 degrees to the right or left. It can be adjusted to compensate for wear or loosening the head by merely loosening or tightening a tapered pivot screw.
