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: Weight placement question

I cut my daughter's car and it weights 2.5 oz. i need help with placing of weights. the design she picked was this. http://i.imgur.com/UwZzP7c.jpg Where is a good place to place weights. I'm guessing that she's planning to run it with the left end as the front, and the right end as the back. If you...

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...

That's a nice analysis of Points vs Times. Thanks for including it!

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.

Re: Tip: Be careful with weird wheelbases!

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...

Re: Tip: Be careful with weird wheelbases!

I find it interesting that they're still using the old Shape N Race Derby name rather than the new StocKar Derby name. Presumably, they're getting their kits from the Shape N Race company rather than from CSB Ministries.

Re: Pinewood Derby Times, Volume 18, Issue 11 - February 20, 2019

I hope that you find this information useful. If you have a unique way of judging cars for design awards, please share your method with me. We used to have judges rate cars in various attributes (e.g., creativity, detail, craftsmanship, etc.) and then we'd sum the scores to get a car's total score....

My question is this. Does anyone have any ideas how to stream line the voting process.
We've always had independent judges choose the award recipients sometime between registration and the race itself.
