Planning Your Pinewood Derby Car
Design Sketches
We recommend following a few quick steps when getting started with planning out your derby car.
Step 1: Before you cut any wood, spend time planning. Look at high-performance cars to see their designs, and talk to past winners about their creations. Study everything about these cars and learn as much as you can.
Step 2: Once you’ve gathered excellent examples, sketch your own design. Even a basic sketch is essential to visualize your car. This also helps in planning optimal weight distribution, which is crucial for high speed. Be sure to include top, side, and end views of the car in your sketches.
Step 3: Try out various shapes to find the ones that minimize air resistance while still looking great.
Weight Distribution
Weight distribution is another essential aspect to consider in your sketches. Well-distributed weight can significantly impact the car's speed. The goal is to maximize the weight (check your race rules, but usually it’s a 5-ounce limit) and position it primarily towards the rear of the car.
Weight distribution plays a crucial role in your Pinewood Derby car’s performance. Placing more weight towards the back can give it that extra speed boost as it races down the ramp. This is because having some weight at the back shifts the center of mass, allowing gravity to pull the car down the ramp more efficiently. Essentially, this setup reduces friction and enhances acceleration; placing the weight too far back might cause the car to "pop a wheelie" and go off the track.
You should know!
To achieve optimal results, aim to position 60-70% of the car’s total weight towards the rear. This strategy can make a noticeable difference and help your car zoom past the competition.
Essential Tools and Materials
To bring your designs to life, you'll need the right tools and materials. Here's a checklist below to help you get started:
- Pinewood Derby Car Kit: Includes a block of pine, wheels, and axles.
- Designing Tools: Pencil, ruler, and eraser for sketching your designs.
- Cutting Tools: A coping saw or bandsaw will help you shape the block of wood according to your design.
- Sanding Materials: Sandpaper of various grits for smoothing your car.
- Finishing Tools: Wood file or rasp for fine-tuning the shape.
- Drilling Tools: Drill and bits for inserting the axles.
- Paint Supplies: Brushes, paints, and perhaps decals for decoration.
- Weights: Tungsten, lead, or zinc for adding weight to your car.
- Lubricant: Graphite powder for the wheels and axles.
It's important to make sure your working area is safe and well lit. A properly illuminated space can help you avoid mistakes and stay more focused on the task at hand. Additionally, it’s crucial to always wear protective gear, such as gloves and safety glasses. These items are designed to protect you from potential hazards and can significantly reduce the risk of injuries while working. Taking these precautionary steps can create a safer environment and help you perform your tasks with better efficiency and greater confidence.
Constructing Your Car
Cutting and Shaping the Block
With your design finalized and materials at hand, you'll begin by transferring your design onto the wood block using a pencil and ruler. Next, securely clamp the wood to your work surface to prevent movement. Using a coping saw or bandsaw, carefully cut along the outline of your design. Go slowly to ensure precision and avoid over cutting.
After the initial cut, use a wood file or rasp to refine the shape of your car. Focus on smoothing out any irregularities or sharp edges. Following shaping, sand the car with progressively finer grits of sandpaper. Start with a coarser grit to remove any large imperfections, then move to finer grits to achieve a smooth surface. This step is vital for preparing the car for painting and ensures that it looks as good as it races.
Assembling Wheels and Axles
Wheel and axle assembly is critical for the performance of your Pinewood Derby car. Begin by preparing the axles: use a file to remove any burrs and polish them with fine sandpaper to minimize friction. Next, carefully insert the polished axles through the wheels and check that they spin freely without wobbling. If wobbling occurs, make slight adjustments until the motion is smooth.
Carefully use the PRO Axle Hole Driller Tool to drill axle holes into your car's body, making sure they are perfectly aligned. Misalignment can cause the car to travel erratically, slowing it down. Attach the wheels to the axles and insert them, ensuring they are parallel to each other and perpendicular to the car's body. Apply a small amount of graphite powder to the axles to reduce friction, which is essential for achieving high speeds on the race track.
Avoid using the pre-drilled holes that come with your car, as they will likely cause you to lose the race. To win, you need to drill your own holes, and the PRO Axle Hole Driller Tool is perfect for this job. While similar tools are available in the market, we prefer ours because it excels at making the precise holes you need. Take it from the Pros.
Optimizing Performance
Weight Distribution Techniques
Achieving the perfect weight distribution in your Pinewood Derby car can significantly increase its performance. Here's how to master this crucial aspect:
• Identify the Ideal Weight: Ensure your car is as close as possible to the maximum weight limit (usually 5 ounces) as this helps increase the downhill momentum.
• Strategic Weight Placement: Place heavier weights toward the rear of the car, but not too far back. Target to position the center of mass about 1 inch in front of the rear axle to enhance both stability and acceleration.
• Secure the Weights: Use strong adhesive or deep-set screws to secure weights to the car body. This prevents any shift in weight during the race, which can affect the car's performance and direction.
Implementing these techniques will help your car gain a competitive edge by optimizing its speed and balance.
Testing and Fine-Tuning
Before you bring your car to the race, it's important to spend time testing and fine-tuning:
Run time trials for your car! You need to know how fast you're moving but you also need to know if your changes, adjustments, and tweaks are improving your overall performance.
Go to your local Scout troop and see if they have a test track. Get creative in finding one. Pick up the phone and make some phone calls to troops or hobby stores in your area. If you want to win, you need to test your car on a real track with a real timer.
Make necessary adjustments. Based on your observations, adjust the wheels, axles, and weight distribution. Sometimes, minor tweaks can lead to significant improvements in performance.
Repeat your testing. Continue testing and tweaking until your car consistently performs well. This iterative process is key to optimizing your car’s performance.
Fine-tuning requires patience, but it’s a pivotal step toward ensuring your car is race-ready and performing at its best.

Finishing Touches
Painting and Detailing
Finally, the fun part. Now that you've mastered the engineering and physics of your car, it's time to paint on its personality. This is your chance to truly make it yours and make it stand out from the crowd.
Prime before painting. Apply a primer coat to help the paint adhere better and to achieve a smoother, more professional finish.
Choose the right paint. Use acrylic paints for their quick-drying properties and vibrant colors. Apply several thin coats to avoid drips and to ensure a sleek finish.
Personalize your car. Add decals, stripes, or custom designs to give your car a unique look. Finish off with a clear coat to protect the paint job and add gloss.
Creativity in painting and detailing adds a unique flair to your car and showcases your craftsmanship at the race. For inspiration on Pinewood Derby designs, check out this list of amazingly creative cars by Pinewood Pro.
Race Day Preparation
The final steps before the race involve crucial checks and preparations:
- Inspect Your Car: Double-check your car for any loose parts or potential issues. Ensure that the wheels spin freely and that all components are securely attached.
- Lubricate for Speed: Apply a thin layer of graphite powder to the axles and wheels to minimize friction and enhance smooth movement.
- Familiarize Yourself with the Rules: Review the race rules one more time to ensure that your car complies with all specifications.
Arriving early at the event allows you to settle in, make any last-minute adjustments, and soak in the exciting atmosphere.
