Pack 308 Pinewood Derby

Official Rules - 2007

1)  General Rules

a.       The Pinewood Derby is open to all registered Scouts of Pack 308.

b.       Each Cub Scout may enter one (1) car and must be present to be included in the competition.

c.       Each car must pass a Pre-Race Technical Inspection before it may compete. Technical inspection and registration of cars occurs just prior to the race.

IMPORTANT NOTE: Car construction should reflect the age and building skills of the Cub Scout entering the car.  Parents are encouraged to help with some of the technical aspects of race car construction, but the idea is to have boys and their parents work on this project as a team – with active participation on the part of the cub.

 

2)  Inspection Procedure

a.       Weight check using Pack’s official scale.

b.       Cars checked for overall length and width.

c.       Wheels measured for compliance and allowed tolerance.

d.       All axles coated with graphite, per Section 3 Item G below.

e.       Loose materials on cars must be removed.

3)  Pinewood Car Specifications

a.       Materials: Race cars must be constructed from the kit provided by the pack . Materials from the kit may be supplemented but not replaced.

b.       Weight: Racecars may weigh no more than five (5.000) ounces (total weight) as determined on the official scales during the pre-race check-in.

c.       Axles: Axles (nails) must be as supplied in the Official BSA Pinewood Derby Kit. No aftermarket axles permitted. Axles may be sanded, polished or smoothed.
The axle nails shall be firmly affixed to the wood of the car body, and MUST be placed in the original 'axle grooves' in the supplied wooden block. No wheelbase alteration is permitted.

d.       Size: Racecars maximum body length - 7 inches, maximum body height - 3 inches, maximum body width with wheels - 2-3/4 inches and maximum body width 1-3/4 inches less wheels as determined by the official gages during the inspection. Bottom of car to track clearance - 3/8 inches.

e.       Weights and Attachment: Weight may be added to the car and will be considered part of the car for purposes of all measurements. "Weight" is considered to be any material on the car that is not provided in the kit. All weight must be securely fastened to the car, e.g. by permanent glue, nails or screws. Weights shall be passive, i.e. non-moveable, non-magnetic, non-electric, non-sticky, non-liquid etc.

f.         Wheels: Only the wheels supplied in the Official BSA Pinewood Derby Kit are permitted. No aftermarket wheels.
Wheel treatment (hub and tread smoothing and polishing) may consist of smoothing or deburring, but not the removal of substantial material from the original wheels or axles supplied with the kit. The following may NOT be used in conjunction with the wheels or axles: hubcaps, washers, inserts, sleeves or bearings.

g.       Lubricants: Only dry, fine ground powdered graphite is permitted. Graphite with any type of additive(s) is prohibited. Cars may only be lubricated prior to or during inspection and not afterwards or during the race. Oil, grease, silicon spar or any other lubricating products or compounds are not permitted.

h.       Car Finishes: Only paint or wax is permitted. No plastic finishes are permitted.

 

3)     Racing Procedures – Double Elimination

a.       Prior to each heat, car numbers and lane assignments (chosen randomly) will be announced. Cubs will join "The Pit Crew" to place on the track and then take their position at the start line. Upon completion of the race, "The Pit Crew" will return the car back to the designated pit area.

b.       Once the car is submitted for entry, no further adjustments can be made except in the case of mechanical failure (see 3d).

c.       The race will be double elimination. A car must lose twice before it is eliminated. Dens will race among themselves for 1st, 2nd and 3rd place. There will also be a race between the 1st place cars from each den to determine the overall pack winner.

d.       Any entry that experiences a mechanical failure will be allowed to re-race if it can be repaired during the same heat. It will count as a heat loss if it cannot be repaired prior to the beginning of the next heat. All repairs of this type must be done with a member of "The Pit Crew" observing to be certain that the car is still race “legal”.

e.       In the event that all cars don’t reach the finish line, the one that goes the furthest is declared the winner.

f.         All rulings by "The Pit Crew" are FINAL.
