Abstract
Abstract A guide assembly is provided with a pair of spaced and parallel guides and includes a carriage mounted on rollers between the guides for longitudinal movement therealong. The carriage can be clamped in position or limited in movement along the guides by means of a pair of slide guides which can be detachably clamped to the guide assembly. A sabre saw is detachably secured to the carriage and the guide assembly is clamped to the work-piece to be cut whereupon the sabre saw and the carriage is pushed along the guide assembly making a straight cut or a bevelled cut in the work-piece, depending upon the setting of the sabre saw assembly. A center pivot bearing assembly is also mounted upon the guide assembly and includes an adjustable work-piece engaging screw engaging the work-piece and acting as a center pivot so that the saw can be used for circle cutting by rotating the blade assembly 90° from the straight ahead position. This circle cutting can also be at a bevelled angle if desired. A further center pivot bearing assembly is provided at one end of the guide assembly and can be used for cutting larger diametered circles in the work-piece.
