We have a variety of car designs with complete models and instructions. Check out our pine wood derby car designs Our blocks are cut to the official pine derby specifications and the axle slots are precisely cut to minimize wheel alignment issues. See our blocks All friction losses in a pine forest derby car come from the wheels and axles. First, check the parts of your kit to make sure they are usable. If a part has a fatal error, replace it. The 5 keys are not enough for you? Want to know all the tricks and secrets of fast pine forest derby cars? Next, you need Speed to the Finish, the most comprehensive guide to pine forest derbies available today. 3. Pine wood derby axles have burrs and crimping marks that need to be removed, and then the axle needs to be polished to give your car more speed.
Mount each wheel on one of the axles you prepared in the step above, and then spin the wheel. Reject it if the wheel wobbles noticeably from side to side or if it turns only a few seconds. Roll each wheel on a flat, dry, clean surface. The wheel must roll in a straight line and not wobble. Reject anyone who follows a curved or wobbly path. You can make the wheels faster by sanding the tread area to remove high marks and other imperfections, and removing the step from the outer hub (removing the hub step can be illegal in some pine forest derby races). We have already made wheels with these modifications. Take a look at our wheels or you can do it yourself with our tools. Remove the external hub step using the Pro Hub razor. Grind the tread with the Pro wheel chucks. Polish the wheel hub bore with the Pro Bore polisher and wax the hub bore with the Pro Bore wax. Your pine forest derby car moves out of gravity and is slowed down by friction.
Friction acts as brakes. Reduce friction and your car will drive faster. Increase friction and your car will slow down. Finding sources of friction and finding ways to reduce them is the secret to a fast car. Here are some ways to reduce friction and increase speed. You can save time by using one of our pre-cut pine wood cars. All you have to do is grind and paint. We can even assemble the weights for you.
More than 25 models to choose from. Discover our pre-cut pine forest derby blocks Pine derby cars are gravity vehicles. You start the race on a sloping track held back by starting pins. When the pins fall, the cars roll on the sloping track towards the finish line, guided by rails. Most tracks are built with a transition from the inclined starting section to a long flat section. On these routes, cars must complete the flat section at the highest possible speed. Another way to make your pine forest derby car is to cut the block into a wedge shape and then add our plastic accessories to create a variety of patterns. Check out our plastic accessories How to build a fast derby car in 6 steps: Pinewood Derby is a great way to teach physics to boys. Basically, the body represents stored energy. One trick to accelerating a car is to remove the mass from the wheels so that less energy is needed to start and keep the wheels running. Less mass in the wheels also allows more weight for the body.
Your car goes down the track out of gravity. If your car is too light, it will have less inertia in the flat part of the track. Make sure your car weighs as close to 5 ounces as possible. Find someone with a scale, buy a cheap scale, or weigh your car at the post office. Add weights until the automatic lock with the wheels and axles reaches 5 ounces. Don`t wait until race night to weigh your car! When I participate in pine forest derby races, everyone is always in a last-minute hurry to weigh their car to add (or subtract) weight. If you wait until the last minute, you may not have time to adjust your car to the optimal weight. Don`t wait to add weight! Put all your weight behind your back. Much has been written about the physics of pine forest derby cars, and this is a rare case in races where heavy = fast. Aerodynamics have little impact in such a short race, but weight does, and the weight at the rear of the car will make your car faster on the flat track.
Tungsten weights are best in most cases due to their high density. If you`re building a pine forest derby car for the first time, I suggest you start with a simple design that only requires a few cuts of the block.

Most people get the basic clues from friends or search the internet, but to be a winner, you need to know all the secrets.
If you had asked me a few years ago, “How do I get my pine forest derby car driven?” I wouldn`t have taken aerodynamics as my key. Since that time, however, I have read one study and conducted another, both of which have shown that the influence of aerodynamics on the performance of pine derby cars is not trivial. Build your pine forest derby car with LEGO pieces from our LEGO block. The block is an official Pinewood Derby pre-cut block with a LEGO plate at the top. Alignment – Let your Derby car drive straight. This may seem like an afterthought to many, but if your Pinewood Racer isn`t driving straight, the wheels will rub against the track, causing it to slow down. Remember, friction is your enemy. This 6-step guide shows the basics of creating a fast pine forest derby car. This will help you build a competitive and fast car. To build a winning car, you need axles, wheels, weights and lubricants. We believe our speed products are the best. Our products have been helping pine wood derby runners for over 15 years.
