Description Product Content 1 Large Tungsten Bar with a weight of 2.1 ounces. Product Specifications Thickness - 1/4 inch Width - 1/2 inch Length - 1-1/2 inch Weight Per Bar - 2.1 ounce (typical) What is Tungsten? Tungsten is a metal with one of the highest densities. Tungsten is 1.7 times more dense than lead, 2.4 times denser than steel, and 2.7 times denser than zinc. From Randy: "This Tungsten Bar is slightly larger in weight and size than twelve of the 1/4 inch tungsten cubes. According to many expert racers, this is the desired amount of weight behind the rear axle for optimum rail-riding performance." How to Use this Product 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. (1) 2.1 ounce nominal weight - actual weight ranges from 2.05 to 2.15 ounces
