ABSTRACT:
A positioning system adapted for guiding a cutting tool for a portable machine tool such as a router with respect to a workpiece for the purpose of machining the workpiece. The system comprises a rigid slide beam having an elongated configuration, an inner connecting end adapted to be rigidly coupled to the tool, and an outer end defining the length of the rigid slide beam, the rigid slide beam comprising a hollow extruded member. The system also comprises a carriage positioning system adapted to be adjustably secured in positions along the length of the rigid slide beam. The carriage positioning system is coupled to the rigid slide beam in a manner to substantially prevent rotational movement between the carriage positioning system and the rigid slide beam. With the present system, when the rigid slide beam is rigidly coupled to the router or similar tool, the system locates the tool with respect to the carriage positioning system while providing a rigid relationship between the tool and the carriage system, substantially without torque-induced rotational twisting of the positioning system.
