Tips & Hints
When your wheel rubs against the axle head it creates friction. To reduce this friction, file the head back slightly using an Axle File to reduce the friction area.
Tungsten weights are ideal for pinewood derby cars. Tungsten is about 1/3 smaller than a zinc piece with the same weight. Therefore, you can pack Tungsten weights in a smaller area to optimize your center of gravity to maximize inertia giving you greater speed at the finish gate.
Don't put a round peg (axle) in a square hole! Axle slots are square but your axles are round, making it difficult to get them to go in straight. Use a drill press or the PRO Driller to redrill the axle slot so you have a straight round hole to insert your axles
