If you don’t know, don’t be the guy that doesn’t ask for directions and then is lost for the rest of the trip. A simple email or text to your scout leader will get you the answer. For most derbies, your car must be built with the parts found in the official BSA Grand Prix Pinewood Derby kit - the wooden block, official BSA wheels, and axles. Paint, decorations, decals, and weights can be added as long as the final car stays under five ounces. The last step is axle preparation and putting the wheels on. The most important thing to remember is to deburr the nails that you received in your kit.
Fast Axles Make the Fastest Car
He ultimately ended up with a car he’s very proud of and is eagerly awaiting competition. If you can stack more weight in the rear, you have more stored energy. You have to balance the weight as described as COG or center of gravity / mass. Tungsten is the last upgrade that I suggest to give you an advantage.

With that said, if I want to build the fastest car, I use tungsten with 2 oz behind the rear axle. Molybdenum disulfide is used when there is high heat & high pressure. A 3 second race with a 5 oz rolling pinewood derby car NEVER reaches the needed parameters to get the benefit of the Molybdenum additive. I have done hundreds of hours of research this and I have visited many professionals in the industry of tribology. Pinewood derby is raced at temperatures of F degrees. A pinewood derby car is a 5 oz rolling application.

You’ll see a lot of product reviews where there is a majority of 5 stars and then 1 stars with nothing in between. This simple data says it all…folks just didn’t get their setup right. Imperfections in your Pinewood Derby Wheels cause friction in many areas. If the wheels are not precision sanded, you can actuallymake matters worse. Turning your wheels on a lathe are the best way to remove imperfections and get a uniform, balanced and finely tuned pinewood derby wheel.

Build a Fast Pinewood Derby Car in 6 Steps
See more details on this new lube idea in Graphite and Lubes. Careful wheel and axle alignment is equally important to prevent energy loss from misdirected motion. Constant testing and refinement ensure that our car stays on a straight course, reducing the chance of friction with the track. In optimizing a Pinewood Derby car, precision in weight distribution and reducing friction are crucial to outperform the competition. Both impact the car’s speed and stability, making these factors top priorities in design and modification. Let’s face it, racing cars is a lot of fun, even if they’re just handheld models.
To ensure the fastest pinewood derby car designs, follow these five keys to ensure success. Once you have your wheels and axles, it’s important to prepare them properly. You can use sandpaper or a file to smooth out any rough spots. You can also lubricate the wheels and axles with graphite powder, which will reduce friction even further.
Designs for pinewood derby cars and how to build a fast pine car. It's as easy as ABC!
The wheel is secured in the lathe and spun at a high speed, then it is sanded orshaved with a tool attachment. The design of our pinewood derby car combines aesthetics with function. We understand that every angle and curve affects the car’s ability to cut through the air. There's no better way to keep your Scout's mind engaged over the holiday break than by helping them build the ultimate car for the upcoming Pinewood Derby season.
We know that the distribution of weight in a Pinewood Derby car greatly affects its center of gravity, which in turn influences stability and speed. Getting the center of gravity just right is imperative for maximum velocity. Axles often arrive with slight imperfections, bumps, and grooves that should be smoothed out. The smoother the axle, the less friction it generates and the faster the car travels.
To aid your Scout with the perfect build-out, here are five simple tips for creating a fast car for the Pinewood Derby. The first Pinewood Derby was held by a Cub Scout pack in Los Angeles, California and has now become a tradition. Each Spring, the boys are given a Pinewood Derby Car Kit which includes a block of pine wood, four plastic wheels and four nails. All cars in a Pinewood Derby must be of a certain size and weight so they have an equal chance to win. Using the official Pinewood Derby® kit will ensure that you start with the correct size. For most derbies, the finished car can weigh no more than five ounces.
Pennies are about the most cost effective weight, but they take up a fair amount of room, so it may be difficult to locate them exactly where you want. We bought 4 ounces of tungsten weights for our car because they are dense and pack to most amount of weight, in a small area. Start by putting the axle into the drill chuck, about 1/4 inch and tightening it.
Look for wheels and axles that are made specifically for pinewood derby cars, as these will be designed for maximum speed and performance. The wheels and axles are crucial to the speed of your pinewood derby car. Look for high-quality wheels and axles that are well-machined and polished. Remove any burrs or imperfections from the wheels and axles to reduce friction.
