My limits are the little I recall from physics classes.
Too long ago. Had to look up proper terms. 8^7

Have you contacted Visacrem?
They may have some data, I doubt the springs were made especially for them.
That was what I wanted to say when I pointed out it would not fit.karl_a_hall wrote: ... overall compressed length will be too long ...
You can most probably compress it to assemble the head but you may hit a physical limit when bringing down the lever.
I guess you'll have to try and see.

You'd miss out on all the fun! 8^D
Check this page at DVG, it lists nine different springs in use in quite a few machine brands and models (with dimensions).
Maybe they have one with the same/similar dimensions as your original springs.
This page may also be of interest to you.
