New way to add weight !! , washer or lead or tungsten.

Hi !

Here is how and a newer way to add weight in a different place, using washers or lead or tungsten.

wood spacers, super glue and a few washers and some masking tape. Not hard to do.

If your scout rules allow, Please check first.



Just take a wheel and go to your local hardware store and find some washers.

Im sure in a few months, someone will be offering lead washers or tungsten washers.









You are going to make a couple of spacers out of wood, and super glue them on to the 1 washer, 2 washers for both rear wheels.

3/16th thick. 3/8th wide and 4/8ths long. (trying to glue like seen in picture, centered.



Now you can glue the 2nd washer onto the first washer that you just glued the two pieces of wood on.




Now--

You need to get some masking tape, and make some strips, the same width as the two washers. you are going to wrap around the washers, 3 to 4 times.
The reason you are doing this. Is to make sure its centered the best it can when you install the washers/wood-glue to body. the tape will also keep the washers snug into the wheel as you do it.





Now, you need to take a extra washer and just set it inside of the wheel. loosely. its there just for a few minutes. then it will be removed.



Now you need to take your axle and push it thru the wheel and the washers with the wood out, dab some glue onto the wood, either on the body, side or onto the two pieces glued onto the washer.

If you use gel super glue, keep in mind, due this with some extra wheels and axles. not the ones you will race with. Why ?

Super glue and gel super glue, leaves a film / haze / mist and can easily exporate a film into those area and slow the car down ! so better to use a extra axle and spare wheel. If you have none, then you might want to use gorilla glue or due this before prepping your wheels and axles.






I don't have pictures , but once installed and the glue dries. take the axle back off and the wheel.


Remove that extra loose washer and carefully remove the tape off the two mounted washers.


Video clip, double click on image to play.



the wheel should be able to spin and not touch the washers.


Here is a picture of two washers on a scale.



If you have a scale, you can check and make sure you get two washers for each side of the car that weigh the same.


4 washers will give you about 3/4 of oz of weight. not allot. but a number to use and reference, if you choose to try this and if your cub scout pack allows you.

And I am sure at some point, they will offer lead washers and tungsten washers.

Some pictures to see what both rears on the car with the washers and wooden spacers.














I hope you find this guide and tips helpful, if you choose to try to do this option. Again check that this will be allowed by your pack.

Pretty cool stuff Sporty

I was hoping you might give a shout out though.

Sporty is merely being coy.

He knows that the Puma Racing Weights are made of tungsten.

I believe that many are using them this month in league racing so it should be fun to watch.

Best,

Very nice Sporty, informative as usual you are.

Fred Wheeler was the first I know of to add weight inside the wheel cavity 5 or so years ago with his very successful league cars. I believe he carved custom lead pieces to achieve the size and weight he wanted for stability and a more aggressive CG, but your method is lead free and thus fore much safer for the kids.

Totally new here (first post), but this was the first post I clicked on to read, and I have to ask if this is serious information, or if it was posted as a joke to slow down the competition (good idea if that was the intent)?
Adding weight to wheels will only serve to keep a car standing still at the starting gate while the others accelerate down the track.
The image shows roughly the results on the moment of inertia by changing the mass of the wheels by filling them with lead or tungsten. I think these examples are closest to the dimensions for a 1999 wheel, new wheels have a bit less material.
