Since I doubt you want to ship that bad boy, maybe you should mention your general area?

Re: Stop section

Any suggestions on how to improve this stop section so that it is less of a demolition derby at the end of each heat? Yeah, our old track had a stop section like that. We solved the problem by building a new track with a completely different type of stop section. Go and do likewise. Okay, you don't...

Re: -|||===[ Check Your Rules ]===|||-

Yep. We aren't BSA, but when there has been a regional derby, we have provided the rules to the regional derby to those who were interested, but we haven't changed our own rules. Fortunately, there haven't been any big issues with the regional derby rules (such as a "four on the floor" rule). But we...

Re: Non-tungsten, non-toxic car

BTW, there are still plenty of pre-82 pennies in circulation - a random sampling from my sofa turned up 6 among 32 pennies. :) Another BTW, those pre-82 pennies work better in souvenir penny presses than the modern pennies that are copper-plated zinc. But yes, pennies are easy to use, easy to find,...

Re: Moving a racer after heats have been run

Our Pack and District requires the scout who owns the car to be in uniform, check the car in and race it. In my 35 years of being involved with the Pinewood Derby I have never heard of someone else handling a scouts car. If this was some special circumstance then I would like to bring it up at our ...

Re: How to build Speedsters favorite car!

Nice job!

Years ago, I build a Hershey bar car, but that was back when Hershey bars came wrapped in foil, with the paper label wrapped around that.

Re: Tips for winning the SLOWest Car?

The idea could be taken even further by gearing to a flywheel. Yep. That's how those flywheel toys work, where you roll them across the floor or table to spin up the flywheel, and then you set them down. The flywheel keeps spinning, and it's geared to the wheels, so the toy rolls across the surface...

Re: Tips for winning the SLOWest Car?

The challenge is to make it to the Finish line but be last in doing so. Absolutely. The most extreme "slow car" would be one with the wheels glued in place. It won't leave the start gate when the pin drops. But it also won't cross the finish line, which is usually a requirement for "slow car" compe...

Re: Help Cars Finish!

When we built a new track, we kept a section of the old track specifically to check the cars on registration night. We set it up on a table with one end slightly raised, and encourage the kids to make sure their car will roll down that test section of track before they check them in. But the change ...

Re: Hello brand new here.

My experience with Krytox is that the spin test doesn't last as long as with graphite, but on the track, under load, the cars are at least as fast as with graphite. Plus, it's a lot less messy to have Krytox at our workshops than graphite (which always left a big black mess). But I'm more experience...

Re: Cars jumping 1 lane only

Without examining the track, all I can say is that there's something different about that lane that causes the cars to jump. If you can't figure out what it is by watching cars jump, then maybe you could video a car jumping and watch in slow motion.

Is the CSB stockar the same in kit type to the CSB Shape N Race kit with the ears and all! Or is this just a name brand Change to there kit? My understanding is that StocKar Derby is the new trademark owned by CSB, replacing the old Shape N Race Derby trademark, which was apparently owned by the ac...

Re: Tip: Be careful with weird wheelbases!

The parts are the StocKar kits. (Not sure what I think of these wheels...I guess they're a step up from the old SNR wheels). We haven't had a derby since CSB switched from Shape N Race to StocKar, and the elementary age program at our church is now Awana, rather than CSB and/or Pioneer Clubs, so if...
