Damper felt replacement

[vince mrykalo]

Let's see, the spring action dampens the fundamental more, and mass affects the dampening of the partials...or is it the other way around...no, i think i was right the first time.  Right?

  Indeed. Bill Spurlock has a nice instructional paper on this subject. Also, especially if the piano is a vertical, are the damper springs strong enough?

  Most damper springs are strong enough. More to the point -- is there enough mass in the damper heads?
