<html><div style='background-color:'> <P>>From: "Delwin D Fandrich"<PIANOBUILDERS@OLYNET.COM></P> <P><FONT style="BACKGROUND-COLOR: #ffffff">></FONT> .... What I would really like to see is a method of rating a hammer's </P> <P>>resilience--that is, it's ability to deform on striking something like a </P> <DIV></DIV>>piano string and then to recover from that deformity. This, combined with a <DIV></DIV>>general ranking of the actual weight of the finished set of hammers, would <DIV></DIV>>at least get us in the ballpark of being able to predict their performance. <DIV></DIV>> <DIV></DIV>>The actual rating system wouldn't have to be elaborate; perhaps just a mass <DIV></DIV>>rating of light, medium and heavy coupled with a resilience rating of low, <DIV></DIV> <P>>medium and high.... </P> <P>Del,</P> <P>Just a reminder that I've published on this list and am making available my hammer weight standards which give us a common lanquage for talking about hammer weight.  For instance if you say "I found that a 1/2 medium zone hammer weight in the bass to 1/4 high in the treble, blah, blah, blah......"  everyone would know what you are talking about within a few tenths of a gram....</P> <P>These standards are the result of thousands of studies by many many techs and they have proven to represent the modern hammer very well..  They also offer ready made specifications for those techs who like to smooth out hammer weight inconsistancies and set hammer weight to a specific level.</P> <P>Available at:</P> <P><A href="http://www.stanwoodpiano.com/SW-HWstandards3.pdf">http://www.stanwoodpiano.com/SW-HWstandards3.pdf</A></P> <P>Please use them and share with others!</P> <P>Thanks,</P> <P>David Stanwood</P> <P> </P></div><br clear=all><hr>Get your FREE download of MSN Explorer at <a href='http://go.msn.com/bql/hmtag_itl_EN.asp'>http://explorer.msn.com</a><br></html>
