How To Cut A Pinewood Derby Car – WARNING: This project involves working with sharp tools. If you are under 18, please be accompanied by an adult.
Place the block next to it. The axle socket is facing you and the large gap between the axle socket and the edge of the block is on the left (see above).
How To Cut A Pinewood Derby Car
1. Lay the wood on its side and mark the side of the block 25 inches above the base (see above).

Note: Your mark should be on the left side of the block (in the large space between the axis and the edge of the block).
1. Position the ruler with the edge of the mark and the corner of the block farthest from the mark (see above). This should be the diagonal of the corner from your mark.
NOTE: This step involves the use of a hand saw. Be sure to wear gloves and safety glasses. Never put your fingers in the bee’s path.
1. Place your saw blade at the end of the line. Make a small cut straight down to create a notch. This helps keep the bee steady. (See the first picture).

2. Using the lot you just created, cut all the wood straight. This results in the formation of two triangular pieces of wood.
3. For the rest of the tutorial, you’ll be working with the part with the axle sockets on the bottom.
Note: Your cut does not have to be perfect. You will sand the wood later.
2. Take the triangular piece of wood with the axle holes (this is the piece used for your car).

3. Using sandpaper, smooth the surface (diagonal surface) of the machine by quickly rubbing the roughness of the sandpaper over it. Do this until the surface is smooth.
Note: When sanding, run the sandpaper along the length of the machine. This way you fold the grain of the wood and make the surface smooth.
1. Tighten the nail around the nail head with one pin (see first picture).
2. Using a second pair of pliers, press the point of the nail (see second picture).

1. Drive a 25-inch nail into the axle under the vehicle (see first picture). Do this on all four wheels. The base of the wheel should be bent from a block of wood.
Note: If the nail does not go in easily, you can tap it with a hammer to help it go in easily. If you do this, check that the nail is inserted into the axle socket. Then hammer the side of the nail (the bottom of the car) to drive the nail into the car.
2. Place duct tape under the vehicle to hold the studs in place.
Note: Be careful when adding decorations that stick to the outside of the car. This can slow down the vehicle. Introduction We’re going to tell you our favorite tricks and tips and give you the basics of why they work.

Below are a few rules that Pinewood Derbies follow, known as the “Rules in a Box”. It is very important to follow these rules, because if one is broken, you will have a sad child on your hands and a lot of time and effort. Not all Pinewood derbies are the same, so check your local Scout District/Council rules to see if there are any exceptions.
After final approval, cars will not be re-inspected unless the car has been damaged during driving or racing. Plus: Check out some great woodworking tips for beginners here.
Wood holds water, and water adds weight. We want weight, but we want to gain weight when it is most beneficial. Heat the oven to 250 degrees, bake the block for 2 hours. All the water evaporates, allowing for more control during the next few steps.
When your block is dry, many people want to cut it into an interesting shape, perhaps turning it into the profile of your dream machine. But aerodynamics rule the day, and the best shape is a simple rim. Like the rear spoiler on a sports car, the wedge shape anchors the car to the road and allows more air to flow unimpeded over the car. Our wedge tapers from 5/16 inch. At 7/8-in. A tape and push rod is the fastest way to cut wire (wear safety gear and follow safety guidelines), but a chainsaw works just as well. Sand the vehicle body to 220 grit.

Another name for this category would be 5 oz. not always equal to 5 oz. The heavier your car is, the faster it will go. It’s the weight range that makes the difference. The ideal center of gravity location is 7/8 inch. in front of the rear axle. Go too far and you lose potential energy (P=9.8mh or energy due to the position of the object). You’re too far back and your car will go flat, killing your chance of winning. Weigh all parts before assembly to ensure your vehicle does not exceed the weight limit. Paint, glue, stickers and more. leave some wiggle room for
Tungsten is an ideal weight because it is heavier for its size, allowing for more accurate placement. You can buy it on Amazon by clicking here.
This is one of those borderline illegal moves (Remember, Scout is reliable). Double check with your local laws to make sure it’s allowed. A light wheel increases your kinetic energy (K=1/2mv
Or body force due to movement). The best way to reduce tire weight is to mount the tires as flat as possible on any sharp surfaces. Also, most wheels don’t round well off the pack, so getting them as round as possible helps a lot. Some people buy the wheels separately and match the number of molds inside the matching wheels. Others polish the inner hub using pipe cleaner toothpaste to remove imperfections in the plastic.

The stick nail axles included in the kit have small ribs along the body and a flat nail head, both of which create friction that slows the wheels down. Align the axles by tapping them in a drill press and sanding them to 2000 grit. If the nail is still in the drill, file and smooth the inside of the nail head. Attach the axles to the car body, add graphite, rotate the wheels and set the rotation time. A good axle setup rotates in about 45 seconds.
To further reduce road friction, raise one front wheel slightly higher than the other so it doesn’t touch the road. When performing this movement, the center of balance must be just below the midline of the body, so that the car does not go off the road. Also, check your local laws to see if this is allowed.
Since only dry lubricants are allowed, the solution most people agree on is graphite. Where do you use graphite? All over; wheels, axles, axle housings. The type of graphite is not important. Everything works, so buy cheap stuff. For maximum performance, rotate each wheel several times to help break down the graphite.
The first step is to study aerodynamics. Open wheels allow air to flow to the front and stay underneath. Next time you’re driving, consider how many wheels are on the road. Nothing. To make the “guards” shape them and mark the centers of the wheels with 1/2 inch. Drill the hole with a 1-1/4-in. Attach the bulbs to the housing.

Most derby cars are designed not to start until the starting pin is fully lowered. But there’s a simple way to let the car move forward while the pin is moving, giving you a quick start. Open a sheet of paper, make it a three-sided rectangle. Mark and punch the areas on the front of the car, making sure the clip does not go through the front of the car after assembly. Install a 1/4-in. on the body and attach the clip ends to the holes with CA glue.

This is a car I made, I modeled it after the F1 Racer. My brother drew the plans and I did the cutting, sanding and painting! I think it turned out really well, I hope you enjoy looking at the finished product, maybe it will be a source of inspiration
