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.
Miter saw comprising a cast base structure having a generally planar work support surface to which a motor powered circular chop saw is pivotally mounted for rotation about an axis generally parallel said work support surface, together with mounting means utilized for mounting the motor powered circular chop saw to the base support structure wherein the axis of rotation is adjustable in a first direction rotationally in a plane generally parallel said work support surface and in a second direction rotationally in a plane generally perpendicular said work support surface so as to enable accurate orientation of the motor powered chop saw relative to the base support structure without requiring excessive accuracy in the initial fabrication of the cast base support structure and a work piece positioning fence rotatably carried by said base support structure.
