Disallowing modification of the wheels and axles slows the races down making wins clearer in a sense. It also ensures equality of the component. You can still fukc up the installation.

Much like Nascar in such that race teams do not get their tires for the race until that weekend, Restrictor plates, and fuel.
but dont they have an automated light sensing device via holes at the finish line and a light from a pool table on top that tells who the winner is

none of mine did. It was always eyeball. Maybe that's why the scoutmaster's kid always won.

I am currently building 3 cars for PACK 409.

The rules say no machining or polishing of the axles or wheels is permitted but in the next line they say that the pinch marks on the nails and the excess flashing from the wheel molds may be removed.

It is generally accepted that chucking up in a hand drill is legal but that also happens to be a strict definition of a machining process.

The goal of the rule is to prevent V and H grooved wheels and the notching of the nails under the wheels to provide a lubricant reservoir, and to reduce friction.


The other item is the shaving of wheels to reduce weight. You can make the wheel have a thinner wall on the tread and the hub.

The physics says that a car with lighter wheels will reach the flat part of the track faster with a higher velocity. But it will loose its speed faster than one with heavier wheels.

On 35-42 foot tracks the lighter wheels tend to win at the very elite levels of PWD. On 45+ foot tracks the heavier wheels carry better down the longer flat.

If you want to see some elite PWD vids check out this link. While I have not participated yet, I believe that you can participate by mailing them a car and they will run it in the monthly race for you.

On one of the PWD boards that I have visited recently I saw photos of a 110 foot monster track that one group was using for PDDR... These are dads that never grew out of PWD.

the fenton area scout council allows weights - most folks use tungsten putty to centralize the mass somewhere just forward of the rear axle.

they also allow the use of graphite lubricant, but not liquid - only powdered lubricant allowed.

while a properly aligned wheel/axle typically won't have the wheel hub rubbing on the body, it can/does happen depending on whom is placing the cars on the starting track.

knowing this, last year, a number of folks chamferred the wheel hub down significantly - as well as the nail head in order to reduce side loading friction. both are currently illegal now.

there has been some talk over the benefit of various treatments on the side of the car body's where the wheel hub would hit in order to reduce friction loads there - some argue a highly polished naked pine is better than any of the polymers/paints/laquers.

in my opinion, those arguing over it spend way too much time on it themselves instead of teaching their kids how to use the freaking power/hand tools in the first place...

One of items that is allowed is to paint the car with a dot of tape over the axle slot. Then rub in some graphite on the bare pine that has been sanded with like 600 grit. Those numbers that come in the car kits look like they will do very nicely to cover the axle slots for painting.


My son while only 6 years old is going to be doing all of the sanding and likely some of the spay painting. We are going to mill the block in a bridgeport and he will be able to turn the knob to make the cuts as I set them up.
