Description: Pinewood Derby Wheel Runout Roundness Gauge Your Pinewood Derby car will be faster if you use round wheels...but most wheels are not round. Use this tool to select the fastest wheels for your car. Insert wheel and rotate the bezel until the needle is pointing at 0. This is your reference point. The indicator reads .001 inches per division. Rotate the wheel while watching the dial on the gauge noting its maximum deviation from 0. Slide the wheel to the right slightly and rotate again. Repeat until all of the wheel tread has been measured. The ultimate goal is that the needle doesn't move as you rotate the wheel. The more a wheel is out of round, the more the wheel will bounce as it rolls. I found that wheels within .003 are adequate. Use the gauge to find four wheels with the least amount of deviation. Wheels are not included with tool.
