Abstract:

A router is coupled to a pair of pivotally connected arms for free swinging movement about a horizontal plane in a space between a template and a workpiece. The router has an upwardly extending guide pin that is engageable with the template and a downwardly extending cutting bit which is concentric to the guide pin and engageable with the workpiece below. The template is in parallel, opposed relationship to the workpiece such that as the guide pin is moved about the template, the cutting bit simultaneously mills the workpiece to produce the sign. In preferred forms, a mirror carried by the router reflects an image of the guide pin to the machine operator during engagement with the template, and the mirror is also located in disposition relative to the operator's line of sight toward the cutting bit such that both the bit and the guide pin may be simultaneously observed.
