Pinewood Derby Weight
What is Tungsten?
The word "tungsten" literally means "a substance of high density", and is derived from the Swedish language, "tung", meaning "heavy," and "sten", meaning "stone." The name is appropriate as tungsten is a metal with one of the highest densities. In fact, tungsten is 1.7 times more dense than lead. Only gold, platinum, and a few other rare and expensive metals have a similar density.
Applications of Tungsten
Tungsten is completely non-toxic and environmentally friendly so it is gaining increased use in weighting applications where lead is not appropriate. For example lead has been banned in many streams, so tungsten is often substituted for lead weight on fishing flies. The high density coupled with the non-toxic nature makes tungsten an ideal metal for this application.
For similar reasons tungsten is a superior product for weighting pinewood derby cars. Tungsten is 3.2 times the density of the no-lead weighting material often used on pinewood derby cars, thus it enables tremendous flexibility in the design of the car. Coincidentally, tungsten has been used by NASCAR for the metal roll cage and as frame ballast to lower the center of gravity of the race car.
How to Use this Product
Each Tungsten Bar measures 1/4 x 1/4 x 1-1/4 inches long. Your 3.4 ounce shipment of Tungsten Bars will contain four bars.
Tungsten Bars can be easily used for pinewood derby car weighting by drilling a series of 1/4 inch deep holes in the bottom of the car and then using a chisel or sharp knife to clean out the pocket. Since the Tungsten Bars are very hard, do not plan to cut off or drill out any extra weight. Instead, use an alternate method to make fine adjustments such as adding/removing tungsten putty, beads, etc.
