I have a chance to buy some used Deco scales that Speedway sells new for $599.95. They are not electric, but have a liquid filled gauge on each scale that measures weight from 0-1,000 lbs. in 20 lbs. increments. Has anyone used these scales before? Are they good enough to use for my hobby stock? Speedway makes it sound like it's real important to have them perfectly level, do they really need to be any more level than the electronic scales? I think i'd be able to buy them for $200 to $300 whitch is about half of what speedway asks for them. Just hoping if people have had real bad experience w/these I'll get a heads up and wont even bother with these scales and just keep savin up for some electronic ones. Thanks for any advice.

I tried a set of scales like you describe.They worked off of hydraulic pressure.Everytime I made a 20 pound lead change the scales would read 100 pound higher or lower.They were really more of a hasstle than they were worth.If you try a set I hope you have more patience than I did.I spent more time trying to figure out if the scales were right than setting up the car.

I have a set of these scales and they work just fine. The pads are somewhat small so getting the tire centered is important and can change your numbers. Making sure they are level is critical no matter what type of scales you have.

Racer0...Have you compared your readings to digital scales? Maybe I didn't give myself time to get the hang of them.

Having them level is not as important as always having them in the same place on the floor.

Never messed with them but i would think that they would show different rating at different times of the year. Hydraulic fluid would show more pressure on a cold 50 degree shop floor in the spring than it would on a 90 degree floor in the summer. Anybody agree with that?

No, I have never compared them to digital scales. So I guess they could be off. But when it come to $300 compared to $1200, that's alot more nights of racing. As for the hydraulic fluid reading different I don't agree. It might take longer to react but the pressure readings will still come out the same. I Think...

Hydraulic fluid isn't like air. The pressure won't change because of temperature. The fluid might ge thick, making it a little slow, but it won't change the final reading. Besides, how do digital scales work? Do they have fluid in them as well? They have to have something in them.

I am no scaling expert, but I think scales being level is just as important, if not more so, than using them in the same place (the whole point of using them in the same place every time is so you don't have to level them every time). If your scales aren't level, the percentages won't be correct. If you put them in the same place every time, but they're not level, they will just be wrong by the same porportion every time.

The whole point of scaling a car is to get the percentages set. To change the percentages, you adjust the ride heights. If your scales aren't level, the relationship of the car to the ground will be different when its on the scales from when its on the ground. Doesn't this make sense?

I trird to **** the level situation out tonite
I put a cotter key under two left scales and could only get a point 1 percent change on any of the three percentages. therefore I think same place is more important than level
We are also prone to change weight and placing of weight by more than 50 and sometimes 100 lbs during the course of a race
so I think this negates out the worry about .1 percent. This is only my opinion.

Ive had both types and there is simply no comparison. My electronic scales are by far the absolute best racing investment I have ever made. They have payed for themselves may times over in better finishes and better knowledge of whats going on with my chassis. The small deco scales were never accurate enough to make meaningful changes with. Many times the numbers were simply too far off to be accurate. Save your money for a decent set of electronic scales, even used and you will be far ahead.

I would hold out for electronic scales. They really are a good investment and almost everyone says after the first year it was the best investment and they should have done it sooner. Keep your eyes open sometimes you can pick up a used set pretty decent. Also I dont think 20# increments is fine enough for this kind of stuff. I'd sooner use bathroom scales as mentioned in the toolbox that these, but thats my personal opinion.

As for leveling them, ideally you want all scales level but sometimes that isnt entirely possible. I would try to get them as close as possible then always scale in the same spot that way when you find a setup that works you can go back to it and it doesnt matter if the floor is perfectly level because you have a reference point to go by.

I used electronic scales for three years and left the team that had them......I have been using bathroom scales for the last six with good success......takes a little more time and patience but I have lots of that!

I agree with driver27, my electronic scales (Rebco 1 weigh) I bought from Speedwaymotors.com are by far the best racing investment we have ever made.
