[Harp-L] Springs for the Seydel Saxony

That sounds like a good approach. What you are suggesting is that I compress the spring to change the equilibrium position of the spring. In the new equilibrium configuration the displacement from equilibrium will be smaller (because there will be less initial compression) and therefore the force due to the spring will be decreased. Perfect!
Hmm ... A small point, but I wonder how much the spring constant will change by changing the equilibrium point. I would think that this probably won't be much of a concern.
I will give it a try this week.
Thanks for the pro-tip!
I love the Saxony chrom slider system except for the stiff spring. If this modification gets me the spring force I want then this harp will be near perfect.
