Del: Been reading the past posts on soundboard springs and have come to = your comments that a leaf spring arrangement would be subject to = "hysterisis" and would not be as effective. Could you define what you = mean by that term as it applies here? Thanks David love Did I say that? Surely not.=20 Hysteresis would only be a problem if leaf springs of multiple layers = were used. Then the breakaway friction between the various leaves might = cause a response problem. (Bearing in mind that I've not actually tried = this.) Otherwise, with a single leaf, I don't see the problem. And I = can't think of any reason to use a multiple leaf spring arrangement for = this application. Using a single leaf spring it should be relatively = easy to figure out a virtually frictionless coupling between a leaf = spring and the soundboard. Assuming, of course, that one really wanted = to use a leaf spring. Del ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
