How to Use Derby Tungsten Cylinders？
Tungsten Cylinders can be easily used for car weighting by drilling one or more 25/64″ or larger diameter holes into the block and then inserting the desired number of cylinders. The hole can then be plugged with a piece of 3/8 inch dowel rod. Since the Tungsten Cylinders are very hard, do not plan to drill out any extra weight. Instead, use an alternate method to make fine adjustments such as adding/removing tungsten beads.
