  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....

Thanks, but I rather suspect even this is going to be overly complex for =
the purpose. It will be some difficult to get a production hammer maker =
to specify the overall mass of a given set, let alone take the =
measurements to break it down into zones. The same, sadly, is going to =
be true of any resilience standard.
