Corner weight scales
just wondered if anyone had any experience good or bad with brands of corner weight scale.
I'm in the fortunate position to be looking at purchasing a set for use on our race cars so any pointers would be welcome.
No disrespect to anyone but not really interested in bathroom scales and 3 bits of wood :-)
Thanks in advance

I've got about the cheapest ones Demon
Tweeks sell. So far they've been great, very easy to use, various displays but the one I use mainly is showing the diagonal percentages.
Only problem I've had was when I was a couple of kilos underweight at Silverstone and got a ticking off from the scrutes, their scales were
showing about 3-4kg less than mine.
The more expensive ones have memories, wireless etc. but frankly for the amount mine get used it really wasn't worth thinking about the extra
expense.
Not very Locost but very BEC

Bob, after paying that price for a set of scales, I would hope that the difference in weight was down to user error!  Either that or the scales at
Silverstone are way out!!

Not much scope for user error really! I suppose you could weigh the car on a non-flat surface, or under-estimate the amount of fuel in the tank/pies
in belly etc. but that's about it.
If you do some searching you'll hear of a few reports of people being caught out by circuit scales, there's no reason why a circuit
weighbridge would inherently be more accurate than a set of computer corner weight scales. Most of them are mechanical scales and 3kg is only 0.5%
error. If you were to be DQ'd then you'd ask to see a recent calibration certificate

Bob, the 'user error' was only tongue in cheek I agree about circuit weighbridges, they are probably as consistantly
'calibrated' as are the circuit noise meters which seem to vary from circuit to circuit!

If anyone read the December edition MSA circular, it referred to an appeal from a competitor about being underweight at Snetterton. Using his own
scales, was overweight, but showed under on Snetts scales and was disqualified.
I vaguely remember that when Sntts scales were tested later they were showing under weight(allegedly could have been the wind rushing through the
scroots bay) LOL
He was reinstated in the results

I managed to get a great deal on some intercomp scales at the autosport show last year, I'm sure similiar deals will be there again next
week.
Can't recommend them enough!

I tried bathroom scales and such like. Its hard work, especially for a novice like me.
I should write up a guide for it one day. I took photos and everything.
Dont help the OP quest for dome decent gear but may help searches in the future.
Track days ARE the best thing since sliced bread, until I get a supercharger that is!
