What is the way to build a Pinewood Derby car that goes the fastest?
Yoshirools
get your local rules first and foremost!!!! read and understand them !!! the speed is in the wheels and axles and the car when finished it should weigh the maximum allowed most times it is 5 ounces. DO THE AXLES AND WHEELS FIRST TAKE YOUR UNCUT PINEWOOD DERBY BLOCK and put it in the oven for 1 hour at 200 degrees F to get rid of moistuer. the more time you spend DOES make a BIG difference. get the tools to help at your scout store get extra wheels too- the're cheap remove burrs from the axles, straighten then flare the nail head ( they have this tool at your local boy scout store)and polish the axles til they shine like a mirror. a drill press is great for this. start with 240 grit sand paper and contiue upwards to emery clothe. use the wheel mandrel in the drill press to to get rid of the bumps on the wheels and make it perfectly round. use the hub bevel inside and outside of the wheel. stuff the axle full of graphite using a testor model paint brush set aside. shape the car wedge cars win the most!! get some lead fishing weights or real car wheel weights to get the car up to weight. the car should weigh 4.3 ounces before paint and wheels. prime paint, let dry 24 hrs. lightly sand 800 grit and prime again, let dry 24 hrs. lightly sand paint, let dry 24, sand paint dry, sand paint dry, sand 2000 grit lightly. glue wheels, let dry test for straight drive and adjust as needed

What is a connected axel of a pinewood derby?
A "connected axle" in Pinewood Derby is a continuous axle rod that goes from one side of the car to the other. They are usually found in "PineCar" brand kits and require small plastic caps at each end of the rod in order to hold the wheels in place. Check your rules if you are planning to use "connected axles". Most well written Pinewood Derby rules usually will NOT allow this type of axle to be used. Standard Pinewood Derby axles are small nails that are used to hold each tire in place (four of them in the standard kit). These are usually the preferred axle of choice. If your rules do not state a specific kit brand or mention the use of specific axle parts, you may be able to use the "connected axle" on your car; however, I do NOT usually find these axles to be an advantage over the nail type axles. Mostly because the small plastic caps are of poor quality and often fall off during racing which allows the wheels to fly off the car. I am surprised that none of the third party marketers in Pinewood Derby have come up with a solution to the solid axle (aka connected axle) problem.
