poss dumb question

[mark christopher]

ok confirm or call me stupid!:woot::thumbsup:

if my car weighs 2000g and i stand each wheel on a scale in an ideal world each scale would read 500g? so i dont need scales more than 1000g max capacity each :confused::confused::confused:

No, them little jewellers/dealers scales you can get on ebay for about 4 quid are ideal.

[Pops]

sounds about right...500g per scale if your weight distro is 50/50 and equal left to right, but obviously it wont be but it aint gonna be 2000g across front axles so 1000g per scale will be plenty

[KevLee]

If you stood each wheel on 4 scales (assuming the weight distribution is 50/50) you would see a reading of 125g on each scale.... but that would be a total of 16 scales which would be expensive :lol:

I know what you mean though. if each wheel sat on 1 scale you would expect to see 500g on each assuming that the chassis is level. If the chassis wasn't level or distribution isn't 50/50 you should still be able to add the 4 figures up to make a total of 2000g.

However, on a buggy, you're not going to see a 50/50 weight distribution, so those jewellers scales may not give a reading.

When doing a weight distribution measurement on my Durga (running weight around 1800gm), the weight across the rear axle was slightly too much to read out (somewhere over 500gm per wheel).

So I use 5kg kitchen scales for the job now. Accurate to 1gm which is more than sufficient!

Well spotted kev I've edited it lol.
Ones I'm looking at a 1000 g per scale

Just had a blond moment

You can do corner weights with only 1 set of scales, just eight one at a time but the othe 3 wheels must be supported at the same height as the scales. On mine 4wd front dished wheels are perfect

I use 1x el cheapo digital kitchen scales from Tesco and prop the other 3 wheels upto the same height as the scale bed. Seems adequate for off road though I'd possibly want something a touch more discerning for 1:12 or TC.

Seems to work for me - although I have noticed that combining the front axle weights and the rear axle weights never seem to equate to the total static weight of the car (which always weighs light compared to the axle weights added together)

Thus I'm never quite sure if I should base my Fr/Rr weight calcs on the axle weight divided by the sum of the 2 axles weights or the axle weight divided by the total static weight?

The inconsistent weights you are getting a probably a result of the blocks not being entirely identical in size to the scale, and the natural "tweaking" of the car as you pick it up and move everything round.

The great thing about 4 scales is that it ALWAYS adds up. Makes cornerweighting or weight distribution measurement a doddle!

I have four cheap kitchen scales. I rarely use them, but when I do, it is very reassuring to know that the readings are consistent and immediate.

These may be worth a look depending on budget

first of all can I take this opportunity to say.....

Stupid!? :p


Just had to say that mark, and you did ask for it, i'm just surprised no one beat me to it! ;)

Anyway I just do the other option that was mentioned, just use one and keep the others at the same height. :)
