Shape and Sand the Car Body

The first step in building your pinewood derby car is to shape and sand the car body. Using a coping saw or a bandsaw, carefully cut the block of wood into your desired car shape. It’s important to keep in mind the aerodynamics and weight distribution of the car while shaping it.

After shaping the car body, use sandpaper of gradually increasing grits to smooth the surface. Start with a coarse grit to remove any rough edges and imperfections, and then move on to finer grits for a smoother finish. Sanding the car body not only enhances its appearance but also reduces friction, allowing the car to move faster down the track.

Install the Axles and Wheels

Once you have shaped and sanded the car body, it’s time to install the axles and wheels. Use a drill with a 1/8-inch bit to create axle holes in the car body. Make sure the holes are straight and aligned to ensure smooth wheel rotation.

Insert the axles into the axle holes, making sure they fit securely. You can use a small amount of glue to ensure they stay in place. Next, attach the wheels to the axles, ensuring they are properly aligned and spin freely. It’s important to pay attention to the wheel alignment as any misalignment can result in unnecessary friction and decreased speed.

Add Weight and Fine-Tune

To meet the weight requirements, add weight to your pinewood derby car. You can use tungsten putty or small weights that can be attached to the car body. Place the weights strategically to achieve optimal weight distribution, which can greatly affect the car’s speed.

After adding the weights, make any necessary adjustments and fine-tune your car. Check for any rough edges, burrs, or misaligned parts that can cause friction. Smooth out any imperfections and ensure that the wheels spin freely without wobbling.

Paint and Decorate

Now that your pinewood derby car is shaped, sanded, and fine-tuned, it’s time to unleash your creativity and give it a unique look. Use acrylic paints and a paintbrush to paint and decorate your car. Let your imagination run wild and experiment with different colors and designs.

Once the paint is dry, apply a clear coat spray to protect the paint job and add a glossy finish. This will not only make your car look more professional but also protect it from scratches and damage during the race.

Test and Race!

Before the race day, it’s important to test your pinewood derby car to ensure it performs at its best. Find a smooth and level surface to test the car’s speed and make any final adjustments if needed.

Finally, on the race day, give your car a final inspection, make sure it meets all the requirements, and get ready for some friendly competition. Remember, the key to winning is not just about speed but also precision and attention to detail.
