Tungsten Weight is the best weight for your wood derby car because it allows you to pack more weight in a smaller area giving you more flexibility in your car design and more accurate weight placement for speed.
Package contains five 3/8" diameter cylinders with chamfored edges for easy insertion. Three .5oz cylinders are .44" long, one .3oz cylinder is .27" long and one .2oz cylinder is .18" long.
Just drill a standard 3/8" hole or holes in your car, insert the weights you need and cover the hole with wood putty so your weights are hidden in the car.
Total weight of the 5 cylinders is 2 ounces.
Your FREE Wheel Spacer Tool has two functions.
One end is a feeler gauge for setting the perfect wheel spacing when you insert your axles/wheels into your car. Just put the spacer against the car body, snug up your wheels and remove the spacer. This is an easy way to set a critical adjustment so your wheels are not too tight or too lose.
The other end of the Spacer Tool is a Drill Guide template. Place the Drill Guide against the car body where you want to drill your 3/8” weight holes and trace the circle with a pencil. You can also use a nail to mark the center point of your drill hole to make drilling easier.
Note to metallurgists: These cylinders are Class 3 tungsten alloy with 95% pure tungsten.
