PineCar P357 Wheel Turning Mandrel

When plastic parts like PineCar wheels are molded a "parting line" is left where the two halves of the mold join. This parting line can increase rolling resistance and slow down your racer. The Wheel Turning Mandrel lets you use a power drill to carefully spin the wheels against the included two grades of sandpaper to eliminate the "parting line"." Don't over do or you can "flat spot" the wheels.
