What is a Pinewood Derby What is a Pinewood Derby

 

A Pinewood Derby race is an annual Cub Scouting event in which boys race hand-made wooden cars on a specially designed track. The first Pinewood Derby race, held in 1953, was the brainchild of a Manhattan Beach, California pack Cubmaster named Don Murphy. A year later, the program was adopted by the National Scouting council and the Pinewood Derby race continues to be a Cub Scout tradition to this day. Any boy registered as a Cub Scout with a pack can participate in a Pinewood Derby race.

To prepare for the Pinewood Derby race, each Scout is given a Pinewood Derby kit. Inside this kit is a block of soft pinewood, 4 nails and 4 wheels. With the help of an adult, boys design and cut or carve the wood into a car based on official specifications for length, width and height. The car can be painted, appliqued and detailed, and attachments can be added as long as the final weight of the car does not exceed five ounces. Prior to an official Pinewood Derby race, cars are inspected and weighed by registered leaders to assure the requirements are met.

The Pinewood Derby race is run in heats and the best overall time in each division is declared the winner. Though the design and implementation of the race is simple, the process is quite intricate. Most tracks have four lanes and each car will run in a different lane each heat. The cars are fueled only by gravity and the time from release to finish line is electronically measured. At the center of each lane is a guide strip that keeps the car in its lane.

Over the years, many Cub Scouts and their parent partners have toiled over how to build the fastest car to achieve victory in the Pinewood Derby race. Tricks and tips have been studied and tested to discover what works and what does not. Win or lose, each participant walks away with the satisfaction of having created something all their own and participated in a time-honored Cub Scouting tradition.

How to Build Pinewood Derby Cars

Difficulty: Moderately Easy

Build a quick little race car.

Instructions

  • STEP 1: Check the wheels - they should be perfectly round. Put a wheel on an axle and spin it. You can't fix wiggly wheels. Replace them now if they aren't perfect.
  • STEP 2: Check the wheels and axles for burrs. Remove them with nail clippers or fine sandpaper.
  • STEP 3: Make sure the wood block doesn't rock when placed on a flat surface. All of the sides should be 90 degrees. If they aren't, sand the uneven sides down.
  • STEP 4: Mark the locations of the axles. Be sure that you'll have at least a 3/8-inch clearance under the car when the wheels are put on.
  • STEP 5: Sketch a full-scale plan on tracing paper.
  • STEP 6: Transfer the design onto the block of wood. Make sure you do both sides and that the front of the car is on the same end on both sides.
  • STEP 7: Use a coping saw to cut just outside of the marks you made. You can sand the extra off later.
  • STEP 8: Drill the axle holes. Make sure they're square with the body. If it's too hard to drill a hole, you can make a groove instead and fill it later with putty. Set the axles in the holes or grooves to make sure they fit well.
  • STEP 9: Weigh your car and all of its parts at the same time. Add lead weights to the scale until you're close to the weight limit. Remember that you'll be adding putty and paint, which will make the car a little heavier.
  • STEP 10: Drill holes in the bottom of the car for the lead weights. Glue them into the holes.
  • STEP 11: Sand the body until it's the right shape. Make the corners smooth.
  • STEP 12: Use putty on the holes where you put the weights and on any other places you might need it - gouges and so forth.
  • STEP 13: Apply a wood primer and let it dry.
  • STEP 14: Paint the car and let it dry.
  • STEP 15: Apply decals now if you're using them.
  • STEP 16: Put a coat of wood sealer on the entire car.
  • STEP 17: Put a wheel on one axle. Turn and push the axle through the axle hole.
  • STEP 18: Put the remaining wheel on.
  • STEP 19: Repeat Steps 17 and 18 with the other wheels and axle. Make sure all of the wheels spin freely.

Tips & Warnings

  • Check with the Boy Scouts of America for current specifications. There are weight and dimension restrictions on Pinewood Derby cars.
  • Collect all of your supplies and tools before you start
  • No Graphite is Allowed (white BSA lubricaint is allowed)
