ok, hopefully be able to reomve one suspension usnig and have a go at measuing spring rate.

I guess the way to do it is:
a) measure free length.
b) measure change in length when a know weight is on them e.g. me standing on top.

correct?

Yes, or put it on some scales (bathroom) and compress it an inch and read the scales.

Try it with different weights if you can and compare your results, or compress it different amounts and read the scales. This will tell you how accurate your measuring method is.

Have at look at the ends of the springs, sometimes they have the poundage on them

They're generally measured in lbs/inch of compression, so use a measured weight (say, 100 lbs.) and measure it. That'll give you the spring rate, and allow you to compare it to others.

cheers - I thought as much. wonder if spring rates will ever go metric

I use my arbor press, a ruler and bathroom scales, seems pretty accurate
