ABSTRACT:
Improved apparatus for routing a groove in the surface of a panel of material. The apparatus includes a base, a first elongate horizontally oriented support arm having one end pivotally attached to the base and having another end pivotally attached to one end of a second elongate horizontally oriented support arm. A milling head is mounted on the other end of the second elongate support arm. The pivotally interconnected support arm pair permit the milling head to be laterally displaced in an infinite number of directions. The application of an upward or downward force on the milling head causes resilient flexure of the support arm pair, the flexure permitting the upward or downward displacement of the milling head and of a tool bit rotatably carried in the milling head. The apparatus utilizes the resilient flexure of the horizontally disposed support arm pair to insure that a groove of constant depth is routed in the surface of a panel of material.
