The s-m-o-o-t-h way to more speed! can a tool this small make a big difference in how your pinewood Derby car performs? the answer: absolutely! it's true that each official wheel and axle set is virtually identical to every other wheel and axle set. However, that also means that every set is just a little bit different. And sometimes, that's all it takes to make a fast car the winning car! with tires, the differences are roundness and smoothness. And the rule is: the rounder and smoother the tire, the faster your car is going to be. And the easy way to make your tires as round and smooth as they can be is the wheel truing mandrel set. Here's how you do it: 1) put the mandrel in an electric drill. (Remember: when working with power tools, be sure to have an adult on hand to help you.) 2) attach a wheel to the mandrel. 3) turn on the electric drill. 4) use the sandpaper sheets (120-grit first, then 220-grit) to true-up your tire's shape and smooth away minor surface imperfections. 5) repeat for the other three tires.
