  • Patent number: 8256475
    Abstract: Adjustable guidebushes and methods for using the same facilitate cutting joint elements into work-pieces to join together two or more of the work-pieces. In some embodiments, the adjustable guidebush includes a guide surface defining a number of outer diameters having different lengths. Positioning different outer diameters of the guide surface to interact with a cutting guide allows one to adjust the fit of the joint elements formed in the work-pieces.

  • Patent number: 7226257
    Abstract: A router bit with a position stop is disclosed. The router bit includes a body with a collar extending outwardly from it and a shaft extending outwardly from the collar. At least one cutter blade is mounted to the body and the cutter blade may be used to cut a profile into a workpiece. The collar has a first diameter, the shaft has a second diameter and the first diameter is larger than the second diameter. The collar has a face formed a spaced distance or height from the transition point between the collar and the body. The face rests against the upper surface of a chuck when the shaft is secured in the chuck. This allows the body and hence the cutter blades to be held a predetermined distance above the upper surface of the chuck. A second router bit may be provided to cut a complimentary second profile in a second workpiece.

  • Patent number: 6736173
    Abstract: A guidebushing assembly for use with an electric router. A guidebushing holder clamps to the router base, and a guidebushing is secured within the holder and used for cutting an inlay by reference to a female pattern. An appropriately shaped and sized recess is cut by reference to the female template while contacting the template with a tapered sleeve secured to the guidebushing. Movement of the guidebushing and sleeve along the axis of rotation of the router cutter permits adjustment in the size of the recess cut by reference to the template.
