Abstract:
An apparatus for selectively drilling holes in pieces of elongate lumber of either a first width or a second width, the pieces of lumber being arranged in a plane and having an exposed surface for being drilled, the apparatus comprising:two elongate parallel guides perpendicular to the plane of the lumber;rail boxes adapted for movement along the longitudinal axes of the parallel guides between a first position and a second position;means for moving the rail boxes along the longitudinal axes of the parallel guides;a planar member extending from the rail boxes and oriented parallel to the plane of the lumber;first and second sets of of drill bits depending from the planar member wherein the lateral spacing of the drill bits in the first set corresponds to the first width and the lateral spacing of the drill bits in the second set corresponds to the second width of lumber;means for driving the drill bits;means for stabilizing the lumber in position to be drilled;wherein the spacing of the drill bits corresponds to the width of a piece of lumber.
