A rolling plate assembly for use in conjunction with a rotary portable power saw having a saw blade, the rolling plate assembly comprising:
- a. a one piece base molded out of a single piece of fiber enriched plastic having a front housing member and a rear housing member, the two housing members interconnected by a first longitudinal sidewall having a raised stabilizer fin, a parallel oppositely disposed second longitudinal sidewall having a raised stabilizer fin that is affixed to a transverse member having a threaded opening, each of said longitudinal sidewalls having a slot identically positioned adjacent said front housing member, said opening is positioned to be vertically aligned with each of said slots, a horizontal flat plate section extending between the front housing member and the rear housing member, at least one stabilizer tube formed into the horizontal flat plate section, and a penetration slot extending through the horizontal flat plate section;
- b. each housing member having a pair of oppositely disposed wheel bearing seats, the front housing member rotatably supporting a front wheel having a cut mark and an interior wheel shaft terminating in a pair of wheel bearings at either end, the front wheel rotatably and removably supported in the front wheel housing by insertion of a wheel bearing into one bearing seat, the rear housing member rotatably supporting a rear wheel having an interior wheel shaft terminating in a pair of wheel bearings at either end, the rear wheel rotatably and removably supported in the rear wheel housing by insertion of a wheel bearing into one bearing seat;
- c. a gear housing attached to said front housing, a flexible adjustment member retained at one end to the gear housing, a bevel adjustment lever retained at the opposite end of the flexible adjustment member, the bevel adjustment lever having a handle at one end and a multiplicity of teeth along its opposite end, a calibrated bevel bracket rotatably attached at one end to the flexible adjustment member and having a multiplicity of teeth along its opposite end which intermeshes with the teeth of the bevel adjustment lever, the calibrated bevel bracket having saw retaining means extending transversely therefrom;
- d. a tilt bracket housing formed on said rear housing and rotatably supporting an arcuate plunge bracket having an interior arcuate slot;
- e. a cutting guide having a frame member that is inserted through the slots in said longitudinal sidewall and affixed to at least one slot by a fix screw positioned in the threaded opening, the frame member supporting a wheel housing at one end, the wheel housing rotatably retaining at least one wheel, a portion of the cutting guide frame member remote from the wheel housing retained in the slots and affixed to at least one slot by a fix screw positioned in the threaded opening so that the at least one wheel extends in a plane perpendicular to the one piece frame;
- and
- f. the rolling plate assembly is used in conjunction with the rotary power saw having a saw blade by having the saw retained adjacent one end by fastening means connected to the saw retaining means of the calibrated bevel bracket and retained adjacent the saw's opposite end by fastening means connected through the arcuate slot of the arcuate plunge bracket, a portion of the saw blade extending through the penetration slot, wherein the saw blade is positioned to be aligned with the cut mark of the front wheel.
