How to Make Fast Pinewood Derby Car Using DOE, Science, and Analytics
Do you want to know how to make the fastest Pinewood Derby Car? I was there, and using the power of Science, DOE, and Analytics let’s discover the answers. There are so many valuable tips and information the web that’s readily available so we don’t need to re-invent the wheel here on Card Derby design, but would if we wanted to go even farther perfecting those settings.
Using a Pre-Cut Car Body?
If you have to start with the perfect pre-cut body make the two modifications below, and you will have a design which will dramatically improve its performance. These same techniques can be used to improve many of the standard designs you see at local Pinewood Derbies.
DRILL OUT WOOD IN THE CENTER OF THE BODY
Fast cars have as much wood removed from the center of the car as possible. This allows for more weight to be placed in the rear of the car. In this photo, I have used a drill to remove wood from the center of the coupe. All of this weight is now free to be relocated to the rear of the car.
PUT THE WEIGHT IN THE REAR
Many people add weight to the car by attaching a long bar of metal to the bottom. Instead, drill three holes in the rear and fill them with lead. If you use a 25/64″ drill bit, you will be able to easily slide standard lead wire into the holes.
