John, I went to Lowes and bought some laminated shelving board and added carriage bolts to each of the four corners so I could level it. It's a little heavy, but it works great. I have four of the Pelouze SP5 scales on it and have plenty of room.

I would have to agree with DancingD, Beefyproducts is the way to go, Jimmy is one of the best around to deal with, Will more than stand behind anything he sells.

I have heard from some people , that they can make you a custom size...I know a buddy of mine wanted a 4 scale board, and they made him one..Give em a call..

Custom board

John; I have a custom built board, big enough for the large scales, at TR. Next time you're down, take a look. Thanks; Ernie P.

John B -

The pelouze scales are really good scales but are to big and bulky!
Your better to use four scales versus two for a more accurate reading faster and easyer.

Also, a flat board takes up less space in you pit box.

If you want to make a scale board then do what I did and use a plastic cutting board , four bolts on each corner and a crosslevel in the middle.

Still use mine from 1987 when I first built the scale board using four food scales back then! :thumbsup:

Tom Pedano. I have his scale board with the pelouze scales. He is making a newer version board now that holds the smaller scales. But he might have an older version laying around. Try checking the members list. Then you can e-mail him.

I'm not sure I get how 4 scales are more accurate...

The homemade front platform are off from anywhere to 1/8 to as much as 1/2 inch or more in all directions.
That why the vehicle weight differently from scale system to scale system.

If you want to measure accurately you need four scales and a perfectly flat
board LEVELED!

This way it measures the SAME from scale to scale and will give you the correct weight percentages.

Also, you need a board without carpet and a hard smooth surface.

If your board is level, and your dummy blocks are the same
height as your scales, those two scales do not know whether the
other set of wheels is on a scale, or a block of wood...
I just don't see where you think you will get a more accurate result
using four scales.

If the back of your car weighs 600g, it weighs 600g.
Whether the front is held up by wood, plastic, aluminum, or a scale...

That's just it. There are not exactly the same.
The scales compress and the dummy blocks stay the same height.

If there off by the size of one thin small spacer on one side of the dummy blocks then the weight percentages will be wrong.

Would it work if your scale system was off?
Yes at putting the vehicle back to the starting weights as long as you use the same scale system.
Will be wrong if you use another scale system.

Now your actual weight percentages are wrong.
And the front to rear weight is off from the start...

I think 4 would be ok but I prefer 2 myself and actually only use 1 most of the time. There's no need to get frt to rear or left to right% everytime you put the car on the scales. Those are not going to change unless you are always moving components around on the car. The scales are to get a base staring point and some repeatability. There are no %'s written in stone to tell how each car will work on a given day. There are so many things that will make more of a difference in the cars handling than if your percentages are off 1%

That's just it. There are not exactly the same.
The scales compress and the dummy blocks stay the same height.

Old diet scales with springs in them compressed... like crazy.
They'd compress 1/2".
Because that type of scale is actually measuring how much
a spring travels, to give you a number.

Digital scales don't work that way, they work on load cells,
and compress very, very, little..
The amount they compress would yield an error factor of
probably less than the tolerance of the scale.

I understand your arguments, completely, and they have merit.
but they are the classic example, of over teching ourselves.

Because the variations are so small that measuring them, especailly
in percentages is nearly impossible.
You simply cannot get the accuracy needed to make these calculations,
using 2 dollar Chinese scales..

To explain where I'm coming from,
just out of curiosity, I set up one of my digital scales on a
surface plate. I then took a dial indicator, and fixture, and positioned
it on the scale platform, and preloaded the scale to 100g.
Zeroed out the dial indicator, and added 200g.
The scale platform compressed .0035"....
35/10,000 of an inch....
Which is about .001" less than the thickness of a piece of heavy paper.

This difference, when viewed relative to a solid block,
is absolutely negligible.
Especially given the equipment, a non-laboratory grade scale
that only reads in 1/10th gram increments and has a
plus/minus accuracy of maybe 2%.........

 

[Mayhem]

bored huh danno? No racing on Sundays sucks. Think you could test the effects of humidity on the scales next? Just kidding, good info, I completely agree.
No 2 scales or dynos are the same anyway.
