The Pinewood Derby Race is one of the most exciting and significant annual events of Cub Scout Pack 51 throughout the entire year. The race will teach boys something about the nature of competition, the “pride of winning” and the “agony of defeat”. "The Big Race” however, tends to obscure one of the primary purposes of the derby;  bringing a boy and his parents together in a creative, shared and meaningful activity- Building the care itself.

The occasion for such an activity in our society is all too rare. Perhaps, the boy will not remember his own little creation of wood, plastic and paint but he may have fond memories of his parents teaching him to use sandpaper for finishing and teaching him to turn the spray can upside down in a paper bag to clear the nozzle. If this process includes casual conversation, laughter and warm feelings and perhaps winning (or losing) the race is not so very important in the long run.

Ø  Once the car enters the church, it must be handled by the scout unless a power tool or hot weights are being used on it.

Tips for construction of a fast car offered by the scout office are as follows

Ø  Fast Cars have thin shape, Cut the car body to a very thin shape.

Ø  Car weight should be maximum, Not a gram over or under.

Ø  If you paint designs calls for cutting away much of the block, use a saw first.

Ø  Paint body parts before assembling them to avoid getting paint on axles.

Ø  Remove burrs on the nail axles before adding the wheels, using sand paper or emery paper.

Ø  Friction is the enemy of speed. If there is a mold seam on the wheels, sand them very lightly. The wheels are hollow and can break if to heavily sanded

Ø  Use white glue, epoxy or model airplane cement to hold axle in body, Measure center distance between axle before attaching. Allow 3/32” to 1/8” between wheels and body.

Ø  Lubricate the axles with powered graphite, No Oil, Grease or Silicone spray should be used. Lubrication oil will slow the spin and dripping oil can foul the racetrack.

Ø  Fishing sinkers or other weights many be inserted in the body to add weight, but the total weight of the car must not exceed 5 ounces. Michaels, any other craft store or the Scout shop in Macon have adjustable weights that are ideal, some screw on so you wont have to drill holes in the bottom to add weight.

Ø  It is very helpful to attend the build date(s) and unofficial weigh in ahead of time to calculate any final adjustment ahead of time. There is not much time on Saturday Morning to adjust the weight.

Ø  If you are not adding your own weight ahead of time, Drill or Carve Holes in the bottom of the car so that liquid lead weight can be poured in.

Ø  Rear weighted cars go faster, Place the car weight in the rear so that fore/aft balance point is about 1 ¼” in front of the rear axles.
