Hi Paul,
You don't try to damp the spring itself, but you do damp the arm. For
suggestions see http://jclahr.com/science/psn/chapman/as1%20damping/index.html
It can be an advantage to mount the damping blade close to the mass.
This system is very flexible. You just slide the magnet fixture further over
the damping blade until you get the correct damping. I have tried 1/16" Al sheet
for the blade glued to SS threaded rod with two part acrylic glue. It works
OK, but it is not so effective.
Regards,
Chris Chapman
