Default sorting out shock spring strengths/rates

Hi there.
I have a box of springs, mixed brands.
What a good way to sort them from harder to softer.
Any tricks to measuring the relative strengths of springs??
Cheers

Let me start off by saying that this will be a difficult job to do accurately without a special tool for measuring spring rates. Lots of unknowns in a box of random springs.

One way of comparing is to simply squeeze two springs agains each other and see which one compresses more.

Another thing to do is to measure the wire diameter and the number of coils. Fewer coils and/or thicker wire is a stiffer spring. That is based on the assumption that the springs are similar material and dimensions.

As above... but the biggest problem is the "progressive rate" of each spring. You really need to match the "brands" or "sets" together. Just ordering for softest to hardest will not always work.

Integy used to sell a spring dyno (I have one and it works quite well). If you can get your hands on one you can do two test lengths on all your springs to work out their spring rate and progressive rate.
