Abstract: A router guide to enable a router to be free floating within selected planes above a workpiece. A support platform is adjustable in height and reciprocally movable in orthogonal directions, within ranges, allowing it to be easily moved to any position over the workpiece for routing. By use of the guide a router can be free floating for free-hand control, can be made to follow a template, or can be set for movement only in a lateral or longitudinal direction, relatively. The platform on which a router can be mounted is movably supported on two parallel bars for lateral movement which are movably supported on two parallel bars for longitudinal movement which are supported by adjustable legs. An adjustable arm extending laterally from the support allows the guide to follow a template outline, or by attaching a peg in the end of the arm the guide can follow a template groove.
