Abstract
A cut alignment device for a rotary saw having a motor which spins a cutting unit which includes a rotary shaft driven by the motor, a circular blade having a central aperture through which the shaft fits, and a blade mounting device for holding the blade on the shaft, the cut alignment device including: a battery power source carried by the cutting unit; and a beam light source, operatively connected to this power source, and carried by the cutting unit; wherein the light source projects a light beam at a shallow angle from the cutting unit directed to intersect the plane of the rotary cutting tool or saw blade, to assist the operator in cutting accurately.

A cut alignment device for a rotary saw having a motor which spins a cutting unit, the cutting unit including a rotary shaft driven by the motor, a circular blade having a central aperture through which the shaft fits, and a blade mounting device for holding the blade on the shaft, the cut alignment device comprising:
- a battery power source carried by the cutting unit;
- and
- a light source, operatively connected to the power source, and carried by the cutting unit;
- wherein the light source projects a light beam at a shallow angle from the cutting unit directed toward the plane of the blade, to assist the operator in cutting accurately.
A cut alignment device for a rotary saw having a motor which spins a cutting unit, the cutting unit including a rotary shaft driven by the motor, a circular blade having a central aperture through which the shaft fits, and a blade mounting device for holding the blade on the shaft, the cut alignment device comprising:
- a battery power source mounted within the blade mounting device;
- a light source operatively connected to the power source and mounted within the blade mounting device, wherein the blade mounting device defines an aperture from which the light emanates;
- and
- a centrifugally-engaged switch between the power source and the light source and mounted within the blade mounting device, to automatically power the light source when the shaft is spinning;
- wherein the light source projects a light beam at a shallow angle from the aperture directed toward the plane of the blade, to assist the operator in cutting accurately.
A non-parallel beam light source for a cut alignment device for a rotary saw, comprising a light source and a light-directing lens assembly, in which distance between the light source and the lens assembly is adjustable, and the distance of the light source from the housing is adjustable, to focus the beam at a proper distance from the housing and also to adjust the angle of the beam relative to the housing, so that the beam leaves the housing at a shallow angle and intersects the material being cut at a desired location relative to the saw blade.
