Abstract: A laser arbor is provided that will display a cutting line on a work piece to be cut by a rotary saw. The laser is operated by a centrifugal switch mounted within the laser arbor along with a laser diode or the like and a battery. Because of the rotation of the laser with the blade and the persistence of the human eye, the moving light spot from the laser appears as a single line, hence it is not necessary as in the prior art to produce light divergence in the plane parallel to the blade plane. For that purpose, it is preferable to employ a light source having a wavelength that lies in a region to which the eye is sensitive, which in practice will typically mean a wavelength in the upper region of the red. Placement of the laser inwardly from the cutting surface of the blade eliminates the danger of any damage occurring to the laser as a result of debris from the cutting process.

Abstract: A miter saw includes a support mechanism for supporting a miter saw unit relative to a base in such a manner that the miter saw unit is both vertically and laterally pivotable. A position determining mechanism serves to selectively determine the position of the saw unit at any of positions including a vertical position where a saw blade is positioned substantially vertically relative to the base, and leftward and rightward pivoted positions where the saw blade is inclined laterally leftwardly and laterally rightwardly from the vertical position by a predetermined angle, respectively. The position determining mechanism includes movable side stopper members and fixed side stopper members on which the movable side stopper members abut, respectively. The movable side stopper members are mounted on a movable member which pivots laterally with the miter saw unit. The fixed side stopper members are mounted on a fixed member which is non-laterally pivotally movably mounted on the base.
