Indian Nations CouncilThe Greatest Show on Earth
A small hand drill is excellent for winding the rubber bands. It also helps speed up the event. Check the ratio of the drill by making one revolution of the crank handle and count the number of times the chuck turns. Most drills average a 1-4 ratio. It would take 40 turns of the crank to give you 160 winds on the rubber band motor. It is advisable to have one person hold the rocket and propeller while the other stretches the bands, about 1 1/15th" beyond the rocket tail, and turns the rubber bands, gradually shortening the distance between him and the rocket.
A handmade fitting of coat hanger wire makes winding easier. The wire for this winder accessory is not included in the kit, but can be easily made from scraps around the home.

The Pinewood Derby is probably the most universally popular and successful family project in Cub Scouting. Like all success stories, the Pinewood Derby requires planning and work by the pack committee and other parents but its value in fun and close family relationships has been proven over many years. A Pinewood Derby can be successful as a District or Council activity, also. Indian Nations Council holds a Pinewood Derby at the Scout-O-Rama in April. It is open to any Cub Scout wishing to enter.
Pinewood Derby cars are simply small models of specified dimensions, created and carved by boys, under the guidance of parents, and raced by the Cub Scouts. They are gravity powered and run down a regulation track. The derby is run in heats, with cars starting from a standstill and running unaided down the ramp to the finish line. A wooden strip placed down the center of each lane guides the cars.
Each pack sets their own rules for the race.
CAR QUALIFICATION RULES
Most packs encourage parent and Cub Scout working together on their car. For some parents this maybe the only time they take an active part in Scouting with their son. Cub Scouts that are from a single parent family may need assistance. Have a Pack wide workshop so Cub Scouts who need help with their cars have the opportunity to receive help. All Cub Scouts need to have the opportunity to experience the thrill of racing. The rules for car qualifying and racing are established by each pack committee or race committee and need to be followed when planning your Pinewood Derby. Below are tested rules from many years experience running and racing Pinewood Derby Cars.
