Each car must pass inspection by the Pinewood Derby Officials before it may compete. This

inspection takes place at the weigh-in, several days before the race, so check the handouts

for details. The Pinewood Derby Officials have the right to disqualify those cars that do not

meet the specifications.

a) No material may be added to or removed from the axles. The use of abrasives or machining to change the surface or shape of the axles is not permitted. The only exception to this is that some of the axles have a small burr at the back of the head where contact is made with the wheel. This burr may be removed.

If possible, you should have your car in race ready condition prior to the weigh in. But for the other

99% of the pack, there will be parent volunteers at the weigh-in to help with last minute tweaks and

to ballast the cars to the 5-ounce limit. Don’t worry about adding weight on your own, it can be

taken care of at a Den meeting or at the weigh-in.

Please read all the rules prior to starting through the qualification process. All

scouts will be held to these rules. There will be NO exceptions. If your car is not brought to the

weigh in, or it does not successfully pass all the checks, you will NOT be able to race.

1. Size: “Adjust” car dimensions, if needed, to qualify for the race. Your car must freely fit inside

our pass / fail dimension box. The attached rules detail what these dimensions are.

IMPORTANT: Some cool looking cars have had parts cut off at the weigh-in because they

were too big – make sure you check the size limits.

2. Wheels will be inspected.

3. Weight: Add or remove weight so that the final weight of the car is no more than 5 ounces

(141.75 grams). We will have the “Official” scale on hand to verify the weight.

4. Lubricant: Apply graphite to the axles and work it in by rolling the wheels back and forth.

You will NOT be able to apply graphite at the race on Saturday.

5. Register: After your car has passed all inspections it will be registered and held in impound

by the Pinewood Derby Officials until race day, Saturday,  March 8, 2008. The cars will be

released from impound and given to the racer just before their first race.
