PINEWOOD DERBY RULES
Each car must pass inspection by the official inspection committee before it will be allowed to compete. Check-in time will begin at 1:00pm and be completed at 3:00pm in the Saint Mark’s Community Hall. NO LATE ENTRIES.
The inspectors have the right to disqualify those cars that do not meet these specifications.
Pinewood Derby Car Dimensions
✓ The overall length of the car shall not exceed 7 inches.
✓ The overall width of the car shall not exceed 2 3/4 inches.
✓ The car must have 1 3/4” clearance between the wheels.
✓ The car must have 3/8” clearance underneath the body so it does not rub on the track.
✓ No part of the car can extend past the lane starting pole; i.e. ‘forked cars’ must have a bumper of some sort that joins the two wheelbases at the front, thereby touching the starting pole.
Derby Car Weight
✓ The car weight shall not exceed 5.0 ounces. If your car is under 5 oz, you may add weight to get it as close to 5 oz. as possible. No car over 5.0 oz. will be permitted to race. No exceptions. If your car is overweight, we will have some tools in the courtyard so you can remove excess weight.
✓ The official pack race scale (which has been calibrated with an official Cub Scout 5oz. weight) that is used at car check in shall be considered final.
Wood, Wheels and Axles
✓ The official pine wood block must be used. The block may be shaped in any way that is desired.
✓ Official BSA wheels must be used. The wheels may not be cut, drilled, beveled or rounded. You may remove the seams and imperfections from the wheels.
✓ The axles may be altered, polished and lubricated (many people use graphite)
✓ Do not apply graphite to the axles inside the Community Hall, please use the courtyard
Car Modifications Not Allowed
✓ Wheel bearings, washers or bushings are prohibited
✓ The car must not ride on any type of springs
✓ No starting devices. The car must be freewheeling.
No loose material of any kind, such as lead shot, may be used
Each heat will be announced. Drivers will report to the starting line and place their cars on the track. All other people must remain behind the barrier. Each car in a round of racing will race four times (once in each of the 4 lanes of the track).
The starter will make sure the cars are on the track properly and then will start the race.
The drivers will then report to the finish line to collect their cars.
The automatic timing system will select the first, second, third, and fourth-place winners. In the case of disputed results or track timing malfunction, the race marshal can elect to rerun race heats.
If a car leaves the track, runs out of its lane, interferes with another car, loses an axle, etc., the heat will be rerun. If the same car gets into trouble on the second run, the contestant is disqualified and automatically loses that race. If, on the second run, another car is interfered with, the heat will be run a third time but without the disqualified car.
Den winners will be determined first. All five den winners plus the three fastest cars (by cumulative timed results) outside of the den winners will advance to the semi-finals round of racing. The first four places from the semi-finals round of racing will advance to the pack championship heats.
Overall design awards will also be given for best design and most original (best design clearly built by the scout without assistance). Den design awards will be given to the best design within each den outside of the overall design winners.
Overall speed awards will be given for first through fourth place based on the results of the pack championship heats. Den speed awards will be given to the fastest cumulative timed results within each den outside of the overall speed winners.
Siblings younger than tigers, sisters, and scouts whose cars do not pass inspection may race their cars unofficially in the single-heat “Den 0” race before the main start.
