Tips & Hints
A lathed wheel means the wheel was turned at a high speed and "sanded" with a cutting tool. Lathed Wheels are perfectly tuned around the axis of rotation giving you the highest performance.
The axle slots that are cut into standard blocks are too tight for BSA axles that are .089" diameter. Small axle slots make it difficult to get your axles in straight. A #44 drill bit is .086", which I find too tight. Consider a #43 Drill Bit, which is a perfect match at .089" for a snug fit.
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.
