  • Patent number: 8156973
    Abstract: A wood working machine is described that includes a mounting plate assembly for supporting a cutting tool, the mounting plate assembly including a base plate, first and second spaced apart intermediate plates on the base plate, and first and second guide plate elements pivotally supported on respective first and second intermediate plates, and a cutting tool support plate slidably disposed between the first and second guide plate elements, the guide plate elements including means defined therein for positioning each of the guide plate elements at selected angular intervals with respect to the respective first and second intermediate plates, whereby the cutting tool support plate is slidably movable on the base plate between the guide plate elements at a prescribed angle. The mounting plate assembly may include laser sources providing crossed laser beams for accurately positioning the tool bit of the cutting tool near a work piece, and light sources for illuminating the tool bit.
