Ladies and Gentlemen, Start Your Dremels!

Our Pinewood Derby takes place on January 28th, 2017, and while you can expect event details from our Wolf den hosts in the coming weeks, we thought we'd share some car-building information to help you get started on the right "wheel," so to speak.

Whether you're building for speed or whimsy, there are plenty of resources available on the World Wide Web to help you achieve Pinewood Derby glory. We've compiled a short list of helpful links, but don't hesitate to contact some of our more experienced pack members, as you'll find a wealth of knowledge across our ranks.

If you start to feel overwhelmed, just remember the Cub Scout motto: Do Your Best. And please don't forget to have fun. Win, lose, or draw, these are memories that you and your Scout will cherish for a lifetime.

Official Rules

Each car must pass inspection by the official inspection committee before it will be allowed to compete. The Inspection Committee has the responsibility to disqualify those cars that do not meet these specifications:
  • Weight – no more than 5.0 ounces (official race scale shall be considered final)
  • Length – no more than 7”
  • Width – no more than 2 3/4”
  • Height – no more than 5” (in order to clear the finish gate)
  • Width between wheels – 1 3/4" 
  • Clearance between car and track – 3/8”
  • No wheel bearings, washers, or bushings
  • Car cannot ride on springs
  • Only official Cub Scout Grand Prix Pinewood Derby wheels and axles
  • Only dry lubricant permitted
  • Accessories, such as steering wheels and drivers, are permissible as long as these accessories do not exceed the maximum length, width, height, and weight specifications
  • Car must be freewheeling with no starting devices
  • Car must have been made during the current Scouting year


If you need additional cars for the adult/sibling races or perhaps you just want a back-up or two, we will have extra car kits available for $5 apiece at our January 12th pack meeting. If you can't wait that long, contact Eric Moody.

You can find various supplies at your local hobby and/or hardware stores, including decent guides for checking your car's measurements, but here's a pro-tip: a postage or food scale works great for checking your car's weight, a key factor for maximizing speed.

And, of course, you can find anything and everything online.


Start with your den leader, who can direct you to the right person and/or resources.
