Ok Pit Crews!   (this means you parents)

Entrants in the annual Pack 230 Invitational often have lots of questions about how to get started building cars, what designs have proven successful in the past, what's legal and what isn't, and how to build a winning entry.

Well, relax!  Help is at hand.  Listed below are a series of links to help you build your racer, some Speed Tips, and some FAQ's to assist in the process.  We don't want any stressed out drivers or pit crews!

Just remember - you and your son are supposed to be having fun TOGETHER!  If building your car is becoming just a "task to be completed"...put it away until a time when it can be fun.  The point here is that you are helping your son learn woodworking, craftsmanship, and sportsmanship.  Don't lose sight of this important point.

Speed Tips!

It all comes down to four simple principles; Weight, Wheels, Clearance, Aerodynamics. Some folks may take exception to my sequence but I'm no physicist, plus I've seen Cubs build derby cars I once saw someone send the plain block of wood down the track against a winning car...the block won - it was heavier, and the wheels were straight!

  1. Weight
    • Push it to the max. The heavier the car; the faster.
  2. Wheels
    • Polish your axles.
    • Polish your wheels.
      • As the plastic wheels come out of the mold a certain amount of sprue is left on the wheel. Carefully trim this off.
      • Make sure your wheel is as round as possible. Eggs don't roll very well.
      • If you use sandpaper to clean up your wheels carefully remove any remaining roughness left over from the sanding process.
    • How many wheels actually touch the ground?  Think about this one.... You have to have at least 3 wheels on the ground to be legal.
    • Mount the axles squarely to the car.
    • A little lubrication never hurt anything....use graphite powder.
  3. Clearance
    • A pinewood derby track has a raised center portion. This part of the track will rub against the bottom of a car if anything protrudes.
    • If your weights mount under the car - be careful. Wooden tracks are notoriously uneven at the track joints.
  4. Aerodynamics  (I have to add this for the engineers out there.)
    • A wedge should be faster than a square car. How many miles per gallon does your SUV get as compared to your Corvette? (Oooops well, perhaps a bad example, but you get the point)
    • Friction is the enemy.

    Conclusion: So, what is the ultimate derby entry? A properly weighted, three wheeled car that rolls straight, has maximum under carriage clearance, shaped like a torpedo.
