Rules for Building your Pinewood Derby Car. Make safety your top priority. This method uses a "winner's bracket" system that begins with every car filling one spot. At the end of each heat, the winning car advances to the next level of the winner's bracket while the other cars are entered in the loser's bracket.
Those cars then race against one another, with the winners of each heat advancing. The final car of each of the two brackets competes with the other for first place. Advantages: The system is straightforward and moves quickly. Each car has at least two chances to advance. Disadvantages: Certain track lanes might be faster than others.
Some fast cars can be eliminated early if they are in the same part of a bracket. Once a race car is eliminated, the Cub Scout who built it may lose interest in the rest of the derby. To use this method, your track must be equipped to record individual race times. If desired, these slots may be pre-drilled before they are used. However, the use of the pre-cut slots is not required. You can de-burr and polish the axles. Wheels may be lightly sanded to remove the molding seam on the tread and the hub may be trued.
No other wheel changes are allowed. You may not use hubcaps, washers, inserts, sleeves, bearings or coatings. Lubrication: Only dry powdered lubricants such as graphite may be used. No lubricant may be applied once the car has been inspected and registered. Scouts who qualify will be allowed to re-lubricate their cars before the final championship race.
Scouts must furnish their own lubricants. Arrow of Light Scouts who have already crossed over to Boy Scouts are still eligible for this event if they placed at the Pack level while still a Cub Scout. NOTE: If any placed scouts cannot participate, please choose another scout to compete to encourage maximum participation. Only one car may be registered by any Scout. Scouts will compete in intra-rank competition.
Short sleeves are recommended. Scouts and Scout Leaders observing the competition are encouraged to be in uniform. Attendance Requirements : In general, Scouts must attend to compete. Cars will not be accepted for drop off. In the case of illness or personal and family emergencies, a Scout may be represented by an authorized agent.
An authorized agent is defined as a sibling or a Cub Scout who is not already competing in the same Rank competition. Classes: Entrants will be separated into 6 groups by Rank. The top three 3 finishers from each Rank will be eligible to race in the final championship race.
The District championship race will be the last race of this event. Registration: Early on-line registration will be available for all entrants prior to race day. On the day of the race, the Scout must be present for check-in and inspection of his car prior to the start time of his race; race officials will assign specific check-in times for each Rank race. Early check-in arrangements can be made for entrants that are not available during the assigned rank check-in and inspection.
Due to the computer entry and timing processes, acceptance of late registrations is at the sole discretion of the Race Committee. Bending your Pinewood Derby axles will make the wheels ride up against the nailhead, which creates less friction than if the wheel is bouncing around and rubbing against the wooden Pinewood Derby car body. It also makes alignment easier. An axle bending tool is the simplest way to do this, and these tools can be purchased at the Scout Shop and many craft stores.
But you can also make a slight bend in the the axle using a clamp and a pair of pliers. You can use a file or fine-grit sandpaper to remove the burrs and polish the axle. One easy way to do this is to clamp the axles back in the drill and let the drill spin the axle while you polish it. Any dry graphite will work well, and you can purchase it at the Scout Shop, craft stores or hardware stores.
Other options for dry lubricants include molybdenum moly or tungsten disulfide WS2 powder. These lubricants are available on their own or mixed with graphite.
They generally cost more, but some people think they are more effective than graphite. Every pack sets their own rules and guidelines for their Pinewood Derby race. There are no official nationwide rules. Check with your local pack, district or council to find the rules in your area.

In the official Pinewood Derby kit, the axle grooves closest to the edge are usually put at the rear of the car. However, you are allowed to orient your car in whichever direction works best for your design.
