OFFICIAL PINEWOOD DERBY RULES

MISSION STATEMENT

It is the mission of the Boy Scouts of America to serve others by helping to instill values in young people and in other ways

 prepare them to make ethical choices over their lifetime in achieving their full potential.

In an effort to provide uniformity among the Cub Scout Packs of the Mushkodany District holding Pinewood Derby Races, the

following set of guidelines and specifications have been adopted. Since these rules and specifications will be enforced at theDistrict Pinewood Derby Race, it is strongly suggested that they be implemented and adhered to at the pack Pinewood Derby

Races. The Inspection Committee holds the right to disqualify any car not meeting these rules and specifications. THEDECISION OF THE INSPECTION COMMITTEE IS FINAL. Since this race is a fun event, the Cub Scout should be

given the satisfaction of building his own car from the kit with guidance and minimal assistance from the parent or otherresponsible party.

CAUTION: Please read over all of the attached instructions and rules before you begin. The rules will be uniformly enforced

regardless of knowledge of them.

 provided in the standard kit; and to race that vehicle against other Cub Scouts who have followed the same rules. Any abuse ofthese basic rules is considered unworthy of a Cub Scout with regards to fairness and honesty. Please participate in this spir it.

K.  Wheels: Do not turn down or machine the wheels narrower than they are now. Wheels may be lightly sanded to removethe glaze and the thin ring around the outside of the wheel. The basic appearance of the face of the wheel may not be

changed. The raised letters "BSA PINEWOOD DERBY" must be seen. The contact area of the wheel must be at least5/16’’ wide and flat. Do not turn down or machine the inside of wheels including hub and sidewall area. The letters BSA

must be seen on the inside of wheels. Excessive wobble of the wheels is not acceptable if it changes racing contact area. No lathed wheels.
