Building a pinewood derby car is a cherished tradition for many, blending creativity, craftsmanship, and friendly competition. For those new to the craft, or even seasoned builders looking to refine their process, understanding the essential tools is the first step towards creating a winning car. This guide will walk you through the tools you’ll need, from basic hand tools to power tools that, when used responsibly and with adult supervision, can take your derby car to the next level.
Essential Tools for Shaping Your Derby Car
The journey of crafting a pinewood derby car begins with shaping the block of wood into a sleek, aerodynamic racer. Here are the tools that are indispensable for this stage:
1. Scroll Saw: Precision Cutting for Intricate Designs
For those aiming for more than just a basic wedge shape, a scroll saw is an invaluable tool. Its fine blade allows for intricate cuts and curves, enabling you to realize more complex car designs.

A scroll saw offers greater control compared to other saws, making it safer and more manageable for detailed work, especially when adults are guiding younger builders. It’s perfect for cutting out the initial car body shape and any decorative elements you envision.
2. Rasp and Files: Refining the Shape with Control
Once the basic shape is cut, rasps and files are your go-to tools for refining the contours and smoothing out rough edges. These hand tools give you excellent control, allowing for gradual shaping and precise adjustments.

Rasps are coarser and designed for quickly removing wood, ideal for initial shaping. Files, with their finer teeth, are used for smoother finishing and refining details. Wearing gloves while using rasps and files is recommended for safety and comfort.
3. Sandpaper: Achieving a Smooth, Race-Ready Finish
No pinewood derby car is complete without a smooth finish. Sandpaper, in various grits, is essential for eliminating scratches and imperfections left by rasps and files, preparing the car body for painting and ensuring optimal aerodynamics. Start with coarser grits to smooth out any remaining roughness and gradually move to finer grits for a polished surface.
4. Optional Power Tool: Drill Press with Drum Sander for Controlled Shaping
For those seeking a more efficient way to shape and smooth curves, a drill press equipped with a drum sander attachment can be a valuable addition. The slow, controlled rotation of the drum sander allows for precise shaping and smoothing of the car body, particularly for curved surfaces.

When using a drill press with a drum sander, always ensure the workpiece is securely held and move it slowly and deliberately against the rotating sander to prevent over-sanding or loss of control.
Tools for Weighting and Balance
Optimizing weight and weight distribution is crucial for maximizing your pinewood derby car’s speed. Here are the tools for creating weight pockets and adjusting weight:
5. Drill Press with Router Bit: Creating Weight Pockets
To strategically add weight to your pinewood derby car, creating a weight pocket on the underside is a common technique. A drill press fitted with a router bit is an effective tool for creating clean and consistent weight pockets.

It’s essential to set a depth limit on the drill press to prevent cutting too deep and compromising the car’s structure. Marking the desired pocket area with a marker beforehand ensures accuracy. This method allows for controlled material removal to accommodate weights for optimal car performance.
Essential Measuring and Marking Tools
Accuracy is key in pinewood derby car construction. Precise measurements and markings are essential for symmetrical designs, accurate cuts, and proper weight placement.
6. Ruler and Measuring Tape: Precision in Dimensions
A ruler and measuring tape are fundamental for taking accurate measurements of the wood block, marking cut lines, and ensuring your car adheres to pinewood derby regulations regarding dimensions.
7. Pencil and Fine-Point Marker: Marking and Outlining
Pencils are used for light markings and initial outlines, while fine-point markers, like Sharpies, are excellent for making clear, visible lines for cuts and weight pocket areas, especially on the underside of the car.
Safety First: Essential Safety Gear
Safety should always be paramount, especially when working with tools, whether hand tools or power tools.
8. Safety Glasses: Eye Protection is Non-Negotiable
Safety glasses are crucial for protecting your eyes from wood shavings, dust, and any projectiles that might occur during cutting and sanding. Always wear safety glasses when operating any tools.
9. Gloves: Hand Protection and Grip
Gloves provide protection against splinters and abrasions when using rasps, files, and sandpaper. They also enhance grip, providing better control over tools and workpieces.
10. Clamps and Vise: Securing Your Workpiece
Clamps and a vise are essential for securely holding the pinewood derby car body while cutting, shaping, and sanding. A stable workpiece significantly improves control and safety when using tools, preventing slippage and potential injuries.
Optional Tools for Enhanced Detailing
While the tools listed above are essential, some optional tools can further enhance your car’s design and performance:
11. Dremel Tool: Fine Detailing and Precision Work
A Dremel tool, or rotary tool, with various attachments, can be used for fine detailing, carving intricate designs, and even polishing axles. However, Dremel tools require a steady hand and can be challenging for beginners to control effectively.
12. Hobby Knife: Precise Trimming and Clean Edges
A hobby knife is useful for precise trimming, cleaning up edges, and making fine adjustments to the car body. It’s particularly helpful for removing small slivers of wood and refining details.
Conclusion: Building Your Pinewood Derby Car Toolkit
Building a competitive and visually appealing pinewood derby car is a rewarding project. Having the right tools not only makes the process easier and more efficient but also safer and more enjoyable. Starting with the essential tools like a scroll saw, rasps, files, sandpaper, and basic safety gear will set you on the path to creating a winning car. As your skills and ambitions grow, you can explore optional tools like a drill press with a drum sander or a Dremel tool to further refine your designs and performance. Remember, adult supervision and a focus on safety are always crucial, especially when younger builders are involved. With the right tools and approach, you’ll be well-equipped to create a pinewood derby car that’s both fast and a source of pride.
