These are the rules included with the kit.
A CUB SCOUT/PARENT PROJECT
KIT NO. 17006
OFFICIAL GRAND PRIX PINEWOOD DERBY KIT
Please read these Rules and Instructions before building your car.
The Pinewood Derby is open to all
Cub Scouts. Cars should be built by the Cub Scouts with some adult
guidance. Any technical assistance should be fully explained to the Cub
Scout so that he can use that knowledge on future projects. Because it
is difficult to establish how much help was given in building the car,
some Packs have a separate Pinewood Derby Race for adults.
Race Committee should decide on rules and race procedures, then have
them printed and distributed to all participants at least two weeks
before the race.
- Width: - 2-3/4" - Length - 7" - Weight - Not over 5 Ounces
- Width between wheels - 1-3/4"
- Bottom clearance between can and track - 3/8"
bearings, washers, and bushings are prohibited. The car shall not ride
on springs. Only official Cub Scout Grand Prix Pinewood Derby wheels
and axles are permitted. Only dry lubricant is permitted. Details, such
as steering wheel and driver are permissible as long as these details
do not exceed the maximum length, width and weight specifications. The
car must be free-wheeling, with no starting devices. Each car must pass
inspection by the official inspection committee before it may compete.
If, at registration., a car does not pass inspection, the owner will be
informed of the reason for failure, and will be given time within the
official weigh-in time period to make the adjustment. After final
approval, cars will not be re-inspected unless the car is damaged in
handling or in a race.
the grooves to ensure that each is at a perfect 90-dearee angle to the
car body. A car with untrue axles tends to steer to one side or the
other, causing it to rub up against the side of the lane strip, slowing
it down. You can check the groove angles by using a square, a
protractor, or even a piece of paper.
Lay square on block to check for squareness and alignment of slot.
Use two hacksaw blades side by side to redress the slots. Use the edge of the square as a guide.
NOTE: If the car design you chose has a narrow body,
make sure the area where the axles are inserted into the body remains
1-3/4" wide, or wheels will not fit over the guide strips of the track.
PAINTING AND WHEEL ASSEMBLY
Apply several coats of sanding sealer; then sand entire car with a
fine-grade sandpaper. Give model at least two coats of fast drying
paint, in your choice of color. When paint is completely dry sand with
a fine sandpaper, apply a final coat of paint and allow to dry
thoroughly. TO FINISH, rub entire car with a rubbing compound. Details
such as windshield, driver, racing numbers, etc., should be added now.
For a super finish apply a coat of auto wax and rub to a high gloss.
Pre-lubricate axles and wheels using, dry powdered lubricant. Do not
use regular oil or silicone spray, since it may soften the plastic.
Slide wheels over axles, then gently tap them into the car body grooves
with a 1/4" dowel or similar object to within 1/32" of car body. (See
Figure 4). Make sure wheels turn freely.
Due to many requests we have eliminated the cockpit section in the Pinewood Derby block to allow for more designs.
