Abstract
An assembly is used upon a powered saw table to accurately cut at a centerline of a workable piece or other material to be cut or, if desired, to accurately cut the cheeks of a tenon to fit a mortise. The trigonometric functions of a right triangle—sine and cosine—are used to assure that as a component of the assembly is moved a certain distance longitudinally, parallel the cutting direction of the saw blade, the guide fence is moved just one-half that distance toward the blade. The longitudinal distance moved is made to equal the width of the piece, thereby indicating a centerline. If the width of the mortise is also considered in addition as part of the longitudinal distance moved, the guide fence is moved toward the saw blade just one-half the distance of the combined widths of the piece and the mortise, to cut the tenon cheeks.
