LEAF SPRING an element comprising a plate or bar or a plurality of superposed plates or bars and which exhibits resilient characteristics when a portion is deflected transversely of length of the element. It would seem to me that in anchoring both ends of the spring the energy losses would be minimized. I gotta go with Dels reasoning on this one so far....course I suppose I am biased too to begin with as this is something I too have pondered on for a while. In anycase it would seem reasonable enough to give it a try. One could actually install such a spring (wooden as Del suggests) pretty easily on just about any instrument and measure the resulting change in sustain and loudness. Might be interesting. I supposed even with an RCT one could come up with some indicative data.... or what ? Richard Brekne RPT, N.P.T.F. Bergen, Norway mailto:rbrekne@broadpark.no
