Always best to stick to the District rules IF there’s a District race to worry about, but most of them in Circle 10 don’t have one.
I ran races for a long time for many different Packs and some District races. I saw everything from no rules, word of mouth Pack traditions, and simple basic rules like these all the way to a 10 page set with requirements for calipers at inspection time.
Some require only graphite or white Teflon for lube and others just say nothing wet dripping on the track. The worst rule I even had to enforce running races was the one about ‘4 wheels must touch the track’. Trying to help a Tiger/Work and their parents to get 4 wheels touching was a big challenge.
I taught my son to use a bandsaw, dremel, spindle sander, and drill press using Pinewood Derby as the project. Then we learned together about axle polishing/bending and why a rail riding 3 wheels touching car will almost always run faster than other cars.
I guess there’s a reason my name on Talk is PinewoodNut.
Needles to say, but I’ll save the 13th to come help. Let me know what I can do.
