You have to use 4 postal weight scales.

oh that sucks i dont have 1 not to mention 4!
i remember seeing someone use a regular scale and they had a strip of thin wood going across with one set of front and rear wheels on it to see how much that side weighed and then they did the other side like that, can you do it that way?

You sure can do it with only one scale. I use my setup to balance the car left to right and front to rear. Heres some pick of my setup it cost me about 15 bucks I got the scale used off of Ebay.

Am i just being pedantic or does doing it with one scale make it more difficult. You need to get the supporting side to the correct height, and when pressures applied to the scale it will compress. Now as the weight of the car varies this would give uneven weights because one side would be lower than the other then wouldnt it? It may just be a few fractions of a gram different but ive not tried it so cant comment.

Well,

One scale will only tell you left/right balance or front/rear (if it can be done)

The only way to do it perfectly is with 4 scales. Because what really matters the most is weight on the diagonals of the car.

That's the way the weight is transfered and both have to be the same weight, of course with the same distribution of weight on th rear and front axles.

There's and older topic where I posted a Excel Spreadsheet to make all the calculations with 4 scales. Just search posts made by me in this Electric On Road Forum.

Heres a little secret tool i use to balance out all 4 tires for my tc3.
http://www.bigjimracing.com/accessories.php * bottom of page

Its called "Sonic Fiddle Stick", its used to measure brush pressure.

But if you bend the wire at a 90 deg angle (just like a fish scale)you can lift each individual tire and measure the weight on each tire.


It works for me and its around 10 bucks, small and easy to use! only down side ...it doesnt come with a backlight display

There is no way that can work from what you just said. You will end up pulling on more than just the weight that is distributed on that wheel.

I know this is an old topic, but I found it while doing a search for a car balancer. I'm looking into making one myself, with a possible computer or other display device interface, a PSP or Gameboy for example, something which doesn't need a mains power source.

I had this problem with my Recoil on Sunday, and just realised earlier tonight that my Blaze has been suffering from this from day one.
