  • Patent number: 6969312
    Abstract: The hub conditioning and alignment tool for a wooden car has a cylindrical handle with two opposed faces. A first shaft extends perpendicular to the first face and a second shaft extends perpendicular to the second face. The shafts terminate in tips with depressions. In use, a child squares the hub on the first face and cones the hub on the second face with sandpaper. A child twists the first tip into the axle hole of the wheel for reaming. The steel tool reduces friction between a hub and a car and aligns a wheel with the track to increase the speed of a car.

  • Patent number: 6904694
    Abstract: The body tool has a rectangular shape with two projections and a central passage for a Pinewood Derby® car body. The holes in one projection align with the other projection. A child places a car body into the passage so the kerf for an axle aligns with the holes in the projections. Alternately, the body alignment tool has two jaws upon a threaded rod closed by a wing nut that grasp a car body. The child then drills through the holes and the car body to straighten the kerf to accept an axle. The child then removes the car body from the body tool and inserts an axle into the new kerf.
