There seems to be a lot to look over and learn, right in the middle of PWD time. We're trying to work on five cars, and deal with a possible new project in June that needs introduced and started soon.
I'm also seeing a lot of entry/registration fees. What is the purpose? To cover the trophy expense? Just curious. I'd rather try and avoid an entry fee, especially in the first year when we are trying to drum up interest. Like I said before, hopefully if we can incorporate the race into our community events, we could get some local sponsorship to cover some or all of our expenses.
Stephen's Dad, I tried sending you a message a few days ago(to get way off subject) about pumpkins. What would you recommend for growing in dry Colorado, that could get to a couple hundred lbs max?
However, my test times, showed the wheels to be very slow .
My web site has pictures of 2 cubmobiles.
I have also detailed instructions and building.
not on the site though
take a look at the pictures on my web site.
We used a rubber washer on the front and back, it kept it stiff and did not move on its own. Coming off the ramp and holds it in place.
I would also appreciate as many different rules that people have as possible. Then we can compare and formulate our own.

I just spent some more money this year getting red farm and fleet red wheels and paint. Oh well Guess we will just play with it in the neighberhood.
The one thing about those wheels is that they were pretty tight going over the axles and the center part comes out pretty easily.
When you get wheels make sure they meet the rules as far as dia and thickness.
You want the biggest dia wheels as rules allow 12" usually and as narrow as rules allow 1.25- 1.75".
I notice on the soapbox car they don't put any washers between the cotter pin and wheel. The cotter pins are pretty close to the wheel also
they have done this, to make the wheels secure so they will not come off easy. But also it create less of a precision precess.
Creates more wobble and so forth. To try and allow a factor of the rider playing the bigger role, versus car.
It could just be, so that the inspectors can see if any mods have been done. Also keep in mind most soap box derby races. the drivers swap there wheels with other drivers. during the race.
To help reduce cheating. The design or set up, is to likely factor in taking them on and off quick during the race.
this rule is to allow that the wheels are not modified and the other driver gets to run with them on the car.
It is not the winner of the 2 heats than may end up winning. its going to be buy tie differance of the win times. that determines the winner.
Well each pack is different on that, Our pack just says must be hard rubber.
If rules say a certain width must be met. I would gather they just would get a ruler and lay it on the ground and with the wheel on top of the ruler.
Or something like that. to come up with the width.
Tread, no tread should not make a differance. Might be harder to check the size.
In regards to checking the thickness / width.
So many packs vary from one to another on some of those finer rules.
Are you trying to combine rules to create your own ? or get a understanding on what the inspectors should look for with a set of rules already in place ?
If i had a chance to start or be in charge for the very first start, creation of a cubmobile race. I would go with all the drivers much use the same size and type of wheel.
Alot of Cubmobile races dont do this.
Since some tread can be narrower than the sidewall. (rubber part of the wheel) (that is placed on the rim of the wheel)
Should be any part of the wheel that could, not exceed or exceed the width of the wheel, or not be wide enough of the overall width of the wheel.
Wider wheels = Better control of the vehicle.
Narrower wheels = Less control of the vehicle.
Weight of the wheel is also a factor. If you are looking at strict or detailed rules.
What I have seen in the our packs, past inspections. If it stands out, a further look is needed.
Overall length of the Cubmobile, Width, Height.
I have not seen them get out the tape measure, is what I am trying to say. I think there main concern is safety and if it stands out from the other cars, they might take a look at it.
I think since the cars are harder to build than a PWD dar. Thay allow for some error.
For example, if the car is 1/4 off in a few area's. The are not going to address it.
If its off 3/4 of a inch. They will address it.
I feel they also factor in, if it was a builder mistake or done with the intentions to gain some edge.
We'll keep everyone up to date as we go, including race day. It's nice to see the scout spirit increase rather than decline.
We had a car spec/rule meeting Sunday and came out with a nice set of minimal but safety concious rules that allow ingenuity. We hand out the specs/rules to the kids at our PWD weigh-in tomorrow, and again at the race this Saturday.
