ABSTRACT:
A motor operated circular miter chop saw is pivotally mounted on a generally horizontal axle pivot bolt about which it rotates in a vertical plane with the axle pivot bolt being carried by a cast support base structure provided with means allowing lateral adjustment of one end of the axle pivot bolt and vertical adjustment of the other end. Angular orientation of the work piece is provided by an angularly adjustable fence rotatably carried by the cast base support structure with the fence having lugs cooperating with an arcuate slot or groove provided in the cast base support structure. The cast base support structure is also provided with an arcuate slot to provide clearance for the circular saw blade while an adjustable stop is provided carried by the cast support base to preclude the circular saw blade from contacting the cast support base structure. Spring means are also provided for biasing the saw to an upwardly pivoted position.
