Derby Worx Pro Wheel Shaver for Pinewood Derby Cars
The Derby Worx Pro Wheel Shaver is one of the easiest, most efficient and cost effective ways to create perfectly round wheels from a molded standard wheel. Not all wheels are created equally, but with a Pro Wheel Shaver, they can be made Hi-Performance. 1. Out of round wheels cause improper alignment at speed. This is something that is greatly mis-understood, but a car can assemble great and roll perfect on a test table but things happen at speed on the track. As a out of round wheel travels down the track and gains speed the axle will raise and drop which will cause the car pull to one side or oscillate depending on how bad or how many wheels are out of round. A fast car will be straight and VERY QUIET, noise is friction. By adding the Pro Wheel Shaver to the Pro Hub Tool a builder can shave the high spots off of molded wheels until they are completely round to the centerline of the hub, this removes all radial run-out to help make a more perfect wheel. 2. The inside edge of a molded wheel in usually not straight. The most perfect aligned cars will still touch the center strip on the track 1 or 2 times on the way down and inside edge of the wheel will effect what happens when this contact is made. If the inner edge is not true, when contact is made it will cause the car to kickback, this will usually cause a radical deflection in the direction of the car. By using the Pro Wheel Shaver, a builder can true the inner edge of the wheel as well to lessen the effects of this contact. One good kick from guide strip contact can ruin the best of runs. 3. Our testing has found that most anyone can easily make wheels that are with-in .001" diameter of each other. Instructions Included
