Try it Paul, it might work.

Thanks Mario!
I really like those types of questions.
The ones that are deemed ridiculous are usually the best.

Tungsten axle or a rear axle support housing made of tungsten?
This is one of my favorite threads.
My first disagreement with Kinser

BTW. Thanks so much to Shovelhead for sending me some TIG welding rods shortly after it was posted

Hi fellas,
Please excuse me if I tend to be long winded in this thread, but this is a subject that I am fascinated by.
Scott,
Please chime in. I am just going to write this because you guys here can teach the CIA a thing or two about keeping secrets.
Many thanks to:
Down4Derby (for being his brilliant self)
Derbydad4hire (for the incredible league and testing of theories in real life conditions)
Quicktime Derby (for his testing of the weights with his super precise cars).
Kinser (for his testing of the weights on his unbelievably precise little machines).
BR. GX
The list goes on
There is no doubt that since the dawn of the BSA wheel, many builders have thought about the possibilities that would be open to them if they could somehow hide the weight inside the wheel void.
We are all taught "thin to win" and so it only makes sense to try to
reduce the thickest part (.25" cubes)
Here is my first attempt at pushing the weights into the wheel void area.
It is a little "diving board" off the body for a .25" cube to sit on.
I did not even know about canting the rears but my instinct (as I am sure many builders before me) was to get some weight in there.

Ok fellas,
The flood gates are open.
No need for weight pockets on this one.
A friend referred to it as "playing Tetris" with tungsten.
(The dull ball in the group is much heavier than the shiny ones.)

Now I had always suspected that the moment of inertia, at the transition, would quicken by hugging the axle plane but it was right around here where Down4Derby opened up.
I quickly realized that we were on the same hunt.
Down4Derby is no joke.
It was as if he were reading my mind on a FEW projects.

D4D had been using steel as his weight, and being the experienced builder he was not afraid to push the tolerances.
He wanted to maximize weight but also create the best wind barrier.
Check out my gaps from the last post. Too big.
D4D made an 11 point list of the benefits of these weights.
Personally, I think his car Double Vision is the poster-child for the possibilities.

Thanks Kinser!
Scott contacted me to tell me about a car "Slime Time" and "Double Vision" that had steel inside the wheel voids.
Slime Time in particular did even better than he thought it would.
After Scott and I started talking about the possible benefits of these little weights we determined that there were many.
I like to use the analogy of a tightrope walker with a long balancing pole.
The tight-rope walker uses the pole to slow his moment of inertia from side to side, which gives the acrobat more time to catch his/her balance.
Now if the pole is weighted at the ends and is long enough to dip down then he/she will in effect lower their COM, making it very difficult to topple over.

Here are some more photos of some weights on cars.
So in other words the weights cantilevered off the body of the car in the wheel voids will quicken the moment of inertia (MOI) at the transition, but also slow the MOI of the car rocking side to side.

Looks to me like they are 3/16" in the wheels. Look at the cubes across the weight pocket, see the difference between the two sizes. BSA wheels are not deep enough to accept 1/4" cubes and put a plastic glue strap across the whole thing. Laserman ran his idea past me about 8 months ago. I told him I thought it was a pretty good idea, but thought if a car got a wiggle having the weights out that far might exaggerate the wiggle. Looks like Joe was on the right track.........good work Joe!TRE said:

Thanks Bill,
That color blue is much more you.
Thanks J And J.
So this is they way I like to attach the weights.
Everything one needs is right here, although you fellas are sure to come up with your own creative methods.

You're Da'man Laserman!
Thanks for sharing this wonderful idea - ca'nt wait to try it out as soon as my weights arrive this week.
Keep the innovative thinking goin'
