Abstract: A mounting frame is provided including first and second relatively stationarily located support portions disposed on opposite sides of an upstanding reference plane. The first support portion includes a horizontal tabletop for supporting a workpiece and the second portion includes a base guidingly supported from the frame for rectilinear shifting along a horizontal path paralleling the plane, a vertical column vertically shiftable relative to the base, a mount carried by an upper portion of the column and router support structure for supporting a router in horizontal position with its output shaft disposed normal to the aforementioned reference plane and projecting toward the latter. The mount is supported from the upper end of the column for rectilinear shifting in a path normal to the reference plane.
