Anyone care to expand on this a bit....I've been trying to figure out a way to check springs, as I have a bunch I received in a trade that are all painted. Thanks guys!

Here is it all setup with a RC4L4ess 8lb spring.

Set everything up so you compress the spring 1 inch and that the scale is at ZERO with the spring in the scale. You will have to reset the scale to zero with each new spring that you put on the scale. This is not NASA accurate, but it is repeatable and works great for comparing springs.



Then compress it and let the scale lock in.



Here is a 30lb spring.


And a 22lb spring.

Very Good idea Scott.Do i just use the scale on the drill press?Or do i setup a dial indicator. Good idea though.:wave:

I have a 2" slug that I insert into the spring, spring are 3". I then set the depth by that, it takes up for any spacing between the press and the spring. Then remove the slug and all is set.

Question ?

You test the spring with a 1 inch compression. I know this is also done for full size cars.

but on the car the turn-down collor is set at 2 turns down from touching the spring. How does this compare?
or is this test - a test to see if the spring is what it said it was.

I have one of the Integy units and it's a nice piece. I don't know how accurate it is on the higher rate springs though.... I do know that there can be a lot of inconsistancies in the spring rate from the same manufacturer within the same "color" rate due to production tolerances and such. There is a considerable amount Of science that goes into rating springs, but if you can come up with a repeatable method that works for you, you will be amazed at what you can learn. Looks like bang for the buck, it would be hard to beat the drill press and scale method. It's essentially what we do on the big cars minus a few widgets and gizmos. Haha
