Building a Pinewood Derby car is a fantastic project for Cub Scouts and parents alike. It’s a wonderful opportunity to bond, learn woodworking skills, and engage in friendly competition. While the basic kit provides the essentials, having the right tools can significantly enhance the building experience and the performance of your car. This guide explores the best tools to help you and your Scout create a winning Pinewood Derby car, focusing on safety, efficiency, and precision.
Essential Cutting Tools for Pinewood Derby Cars
The first step in crafting your derby car is shaping the block of wood. While a coping saw from your garage might seem sufficient, investing in more precise cutting tools can make a significant difference in ease and accuracy.
Scroll Saw: Precision Cutting for Intricate Designs
For intricate designs and smoother curves, a scroll saw is an excellent choice. As highlighted in the experience of a young builder, a scroll saw offers superior control for cutting out the basic car shape. Its fine blade allows for detailed work, enabling you to create aerodynamic profiles and unique aesthetics.

Safety Note: Always supervise children when using a scroll saw and ensure they wear safety glasses. Start with slow speeds and practice on scrap wood to get comfortable with the tool.
Rasps and Files: Shaping and Refining Your Car Body
Once the basic shape is cut, rasps and files become indispensable for refining the car’s body. Rasps are coarse tools ideal for quickly removing wood and creating initial contours. Files, with their finer teeth, are then used to smooth surfaces and achieve the desired aerodynamic shape. Using a rasp followed by files allows for gradual refinement and precise shaping.

Safety Note: Gloves are recommended when using rasps and files to protect hands. Secure the workpiece in a vise or clamp to ensure stability and prevent slippage during shaping.
Sanding and Smoothing Tools for a Fast Finish
A smooth car body is crucial for reducing friction and maximizing speed in a Pinewood Derby race. While sandpaper is essential, power tools can expedite and enhance the sanding process.
Drum Sander and Drill Press: Controlled Sanding for Smooth Surfaces
A drum sander attachment for a drill press provides a controlled and efficient way to sand the curves and contours of your car. By chucking a drum sander into a slow-moving drill press, you gain better control compared to handheld power sanders, minimizing the risk of over-sanding or creating uneven surfaces.

Safety Note: Always clamp the car body securely when using a drum sander and drill press. Wear safety glasses and avoid applying excessive pressure.
Dremel Tool: Fine Detailing and Precision Sanding (with Caution)
While a Dremel tool can be tempting for its versatility, it requires a steady hand and careful control. For experienced builders, a Dremel with sanding attachments can be useful for fine detailing and reaching tight spots. However, for beginners or younger Scouts, it can be challenging to control and may lead to unintended material removal. Consider using it for very specific, small-scale tasks.

Safety Note: Always use a Dremel tool with caution and proper attachments. Practice on scrap wood and wear safety glasses and a dust mask.
Weight Pocket Tools for Optimal Performance
Weight placement is critical for maximizing a Pinewood Derby car’s speed. Creating a weight pocket allows for precise weight adjustment and optimization.
Router Bit and Drill Press: Creating a Controlled Weight Pocket
Using a router bit in a drill press is a safe and effective method for creating a weight pocket on the underside of the car. By setting a depth limit on the drill press, you can control the depth of the pocket and prevent drilling through the car body. This technique allows for a clean and consistently sized pocket for adding weights.

Safety Note: Securely clamp the car body to a piece of plywood for stability. Make multiple shallow passes rather than one deep cut. Always wear safety glasses.
Conclusion: Equipping Yourself for Pinewood Derby Success
Having the right tools not only makes the Pinewood Derby car building process more enjoyable but also significantly improves the final product. Investing in quality tools like a scroll saw, rasps, files, and considering controlled sanding and weight pocket creation methods can elevate your car’s performance. Remember to prioritize safety and adult supervision, especially when power tools are involved. With the right tools and techniques, you and your Scout can build a Pinewood Derby car that’s both a source of pride and a contender on race day.
