  • Patent number: 8057286
    Abstract: A sanding block and a kit for sanding curved surfaces are provided. The sanding block includes an elongated body which has a first sanding surface; and a sandpaper removably affixed to the first sanding surfaces wherein the body is elastically deformable such that the block can conform against a curved surface to be sanded.

  • Patent number: 5337523
    Abstract: A hand-held sander having inserts that interchangeably fit a holder. The inserts have an exterior surface for supporting sandpaper or the like, and that surface is contoured to match a particular surface detail of a vehicle body or other workpiece. The holder includes a shell having a somewhat U-shaped cross-section defining a slot along one edge, and the insert has a spline that slides within the slot when removing or installing the insert. Either or both ends of that slot are selectively enlarged by means of a cam attached to an end member of the holder.

  • Patent number: 5140784
    Abstract: A tool guide temporarily attachable to vehicle body panels or other surfaces to provide a straight edge, and contour sander for use in connection with a straight edge. The tool guide includes an elongated member having a longitudinal edge surface for guiding a work tool, and suction cups mounted on tongues extending laterally from the body of the tool guide. The tongues are angled in relation to the body, so that the tongues exert a cantilever force urging the tool guide against a surface when the tongues are secured against the suction cups. The contour sander includes a number of flat blades mounted side-by-side and each having a longitudinal edge for contacting a contoured work surface. A clamp holds the blades in parallel juxtaposition and selectively loosens the blades for conforming contact with the contour. Finger grips are formed at the ends of the blades, allowing the operator to raise or lower any particular blade and obtain a sharper or more accurate reproduction of contour if desired.
