ABSTRACT:
An optically guided power sabre saw is disclosed. The optically guided power sabre saw includes a housing, a base plate attached to and displaced a distance from said housing, a right vertical support and a left vertical support both disposed in the distance and connecting the base plate to the housing, internal drift connecting apparatus disposed internally to the housing and including a saw blade having reciprocating motion so that the penciled or inscribed line followed by the saw blade during the cutting process is automatically corrected, and external drift correcting apparatus disposed externally to the housing and on the base plate so that as the saw blade travels along the penciled or inscribed line, any drift off the penciled or inscribed line would be detected by the right and the left photoresistors and instantly fed to the blade drive motor for the saw blade correction.
