Results of the Pinewood Derby. With just weight added to the equation, the average time was 3.288 seconds. The difference in time between the quickest and slowest automobile was 0.188 seconds, or about 23 inches. With graphite, the average time was 2.994 seconds, which is about 44 inches quicker than without graphite (0.353 seconds).
The DERBY XTREME is the fastest pine derby car kit available anywhere on the planet, and it is the fastest pine derby car kit available anywhere on the planet. This vehicle has been banned from the majority of BSA Pinewood Derby races since it totally kills any competitors. There is no sympathy for this vehicle, and no one is taken into custody.
Using an oven, bake the block: Prepare your block of wood by baking it at 250 degrees for around two hours before proceeding with the rest of the process. This will eliminate moisture and make the wood lighter. In this way, you will be able to distribute more weight to the back of the Pinewood Derby vehicle, which is where you want it.
Santiago concludes that by applying lubricant to the wheels of his automobile, he will be able to boost the average speed of his vehicle to 29.5 cm/s.
Build a Fast Pinewood Derby Car in 6 Easy Steps with This Guide
Step 1: Reduce friction in order to accelerate your vehicle.
Step 2: Lubricate the Axles and Wheels of the vehicle.
The third step is to prepare and polish the axles, which are critical for speed.
Step 4: Align and adjust your wheels to maximise their speed potential.
Step 5: Increase the mass of the object to increase its inertia.
A fast Pinewood Derby® vehicle may achieve speeds of over 20 miles per hour when it is properly constructed. For a little piece of wood, this is rather impressive! In fact, if a Pinewood Derby® vehicle racing down the track were scaled up to the size of an actual automobile, it would be travelling at speeds in excess of 200 miles per hour. That was lightning quick!
Application: Apply one drop of lubrication to each axle. Directions: Allow the grease to run to the end of the axle by tying the axle down to the ground. Place a wheel on the axle and tighten the bolts. The wheel should be spun multiple times. Remove the axle and use a clean, soft cloth to wipe away any remaining lubrication. Install your car’s wheel into the axle and secure it to the vehicle.
Weights for your pinewood derby vehicle may be added in a variety of ways, as shown in the list below. Top weight made of zinc. Weights for lead wires. Weights made of tungsten. Canopy made of tungsten.
Start with CAMI 400 grit (30 micron = 30 m = 0.03 mm) wet/dry sandpaper and work your way up. Strips of 1/4-inch sandpaper several inches in length should be cut from the sandpaper. Using a wet paper towel, sand the exposed section of the axle for roughly 30 seconds while the axle is spinning at a high rate. Keep in mind that you should polish beneath the axle head.
The majority of the weight should be distributed towards the back of the vehicle. These examples explain how to drill the weight holes in the bottom of a vehicle, the side of the automobile, and the back of the car. Keep your distance from the axle slots to at least 1/8 inch.
Which end of a pinewood derby vehicle is considered the front end? Either end of the block may be used as the front of the vehicle, however the end of the block that is furthest away from an axle slot offers you an advantage if it is used as the front of the car, as shown above. The rationale for this is that if the rear slot is near to the end of the block, you may move the weight of the vehicle farther back on the chassis.
Paint simply adds a few grammes to the total weight (hundredths of a ounce). We usually weigh up to 4.9 oz and then make one final weight adjustment at check-in.
BSA wheels that have been lightly sanded This wheel should be acceptable in pinewood derby races in which any of the following criteria are specified: The diameter of the wheel must be more than 1.18″. Mold marks on the wheels may be removed by lightly sanding the wheels, but the wheels may not be altered in any other way.
Despite the fact that they were made on a lathe, all of the tyres are out of balance. It is next necessary to balance out the wheel by removing extra weight from the heavy side or by adding weight to the light side [for example, by applying nail paint or whatever] until a balanced wheel has been created.
The Pinewood Derby Axle Installer is an important tool in the Pinewood Derby community. Lubricate the wheel and axle – Slide the axle into the wheel. Place the wheel/axle on the base so that the pointed end of the axle is facing up and secure with screws. The Axle Guide should be inserted into the axle slot. With your thumb, secure the Axle Guide in place before gently pressing the car body straight down on the axle.
