Pinewood Derby Race Rules

Cub Scout Pack 21 – Grand Prix Committee - 2004

Specific Inspection Rules for Official Grand Prix Pinewood Derby Kit

 

 

PLEASE READ BEFORE STARTING YOUR PINE WOOD DERBY PROJECT

 

The Pinewood Derby is one of the most popular and successful special events in Cub Scouting. Like all successful activities, it requires planning and preparation, but its value in fun and in strengthening family relationships has been proven over the years.  

Pinewood Derby cars are simply small model cars of specified dimensions, created, carved, and assembled by the boys, under guidance of their parents or other family members. The cars are gravity powered and run down a regulation track. The race can be run indoors or outdoors.

 

A. THE WHEEL AXLE (plated nail)

  1. Axles of Pinewood Derby model car kit MUST BE USED.

  2. If desired, any burr or seam on any surface of axles may be lightly skimmed off with a fine abrasive.

  3. Diameter of axle must be maintained.

  4. Do not build up axles with any material and then turn down with lathe.

  5. Do not add bearings, washers, bushings, tubes or spacers to axles.

  6. Lubricate with a powdered lubricant. No oil or liquid spray is permitted. Oil may soften the plastic.

  7. A drilled hole may be used in place of groove.

  8. A change of wheel base centers is acceptable.

 

B. THE WHEELS

  1. Wheels of Pinewood Derby-model car kits MUST BE USED.

  2. If desired, the burr and seam on contact surface of wheels may be lightly skimmed off with any tool or material available.

  3. If burr and scam are removed from contact surface of wheels, then the surface must be flat and square to side of wheels. In either case, width and thickness of contact surface to be maintained.

  4. No holes can be drilled through wheels to remove material and no material can be removed from inside of wheels, except burrs.

  5. No weight can be added to wheels.

  6. Wheels are designed to be and will be wobbly on axles.

  7. Hubcaps are not permitted.

  8. The wheels may not be rounded or have a "V" shaped surface.

C. THE WEIGHT

Because of variance in scales used in different Cub Pack Pinewood Derbies, a tolerance of plus one gram will be acceptable.  For the District Derby, the reading of the scales used at registration will be deemed accurate.  Make sure that weight is firmly attached to the car. Note, 5 oz. = 0.31 lb. = 141.75 grams.

 

D. OTHER CONSTRUCTION RULES

  1. Dimensions of car must fit within gage at registration.  No modifications of any kind are permitted after registration.

  2. Attached accessories are acceptable if they are secure and stay within maximum dimensions of car.

  3. Pre-cut designs, show wheels and axles are not allowed. Other accessories are acceptable. Refer to the Cub Scout Grand Prix, Pinewood Derby Guidebook* as a guide in building your Pinewood Derby car.

    Note: many tips are not allowed by the above rules ... all tips can be used in modified (non official district) competition though.

  4. Don't forget to check groove square ness to end of block for proper alignment. Also check length of block for regulation length, and minimum width of chassis.

  5. Don't forget to maintain clearance of 3/8" from bottom of car to track surface.

  6. Officials have the right to disqualify a car at anytime, if it has violated Derby rules.

Good luck and happy racing….
