Abstract: A fixed base router is provided comprising a base having a central bore. The router includes an adjusting ring rotatably affixed to a base upper end, being coaxial with the central bore, and having a series of gear teeth formed thereto defining a ring gear. A motor housing, including a motor for imparting rotational motion to a tool holder, is threadably engaged with the adjusting ring. A pinion gear, journaled for rotation relative to the base, is engaged with the ring gear, and is coupled for rotation with a dial extending from the base. The base is adapted to prevent rotation of the motor housing relative thereto, such that rotation of the adjusting ring axially translates the motor housing relative to the base. The router includes a scale and indicator for indicating fine adjustment of the motor housing relative to the base.

Abstract: An object sensor for sensing objects hidden from view behind a first wall surface. The object sensor has a housing having a front surface with a display and a rear surface. The object sensor also has a sensing system and provides additional functions. The additional functions can include a distance detector, a computing system working in conjunction with the distance detector to determine the distance between the object sensor and a second wall, a tracking mechanism, and a projector to project a beam at predetermined distances. The object sensor may further have a level or a location marker.

Abstract: A router having a base and an adjustably positioned motor assembly is provided with a pair of ergonomic elongate handles on opposite right and left sides of the motor housing. The elongate handles which are connected to and spaced from the motor housing by a pair of bridge members are ellipsoidal in shape when viewed in a transverse side elevation. Each elongate handle has a longitudinal length L having a large upper end, diameter Z and a lower small end diameter Z′.
