Pinewood Derby Axles

You will rarely find a factory Pinewood Derby axle that is straight.  How can you tell?  Take your axles and chuck them in a drill press approximately 1/2" from the head.  Now spin the axle at a high RPM.  Notice the wobble?  Yep, the axle is not straight.  Now chuck it closer to the head.  The wobble may be less or even disappear.
