This is a wedge cut from the Official BSA Pinewood Derby Block. This will save you some valuable time... especially if you don't have a router. The weight pocket rests between the two axle slots and is perfect for a variety of weights.
This is a "semi blank canvas" you need to create a race-legal pinewood car that has a look and an edge that are all your own. You can race it as is or do a little carving and shaping to make a unique racing machine. You will get a basic wooden wedge shaped block that's shaped to meet Boy Scouts of America regulations. It simplifies the most challenging parts of custom racer design — you just start here and add your choice of Pinewood Derby® wheels, weights, paint and decals.
