From Randy:
"Tungsten Rods combine the simplicity of cylindrical weight with the low height benefit of cube weight. These tungsten rods allow thin cars to be built without creating underbody pockets."

How to Use this Product

Tungsten Rods can be easily used for pinewood derby car weighting, and can result in a more aggressive COG than can be acheived with 1/4 inch tungsten cubes.

Drill 19/64 inch diameter holes into the side of the block (a drill press is recommended). Then cut out the car. Glue rods in place, fill the holes, then sand and paint. A small hole in the bottom of the car is recommended for final weight adjustment iwth Tungsten Putty.
