I think the most effective voicing work is done at the crown, but=
 not deep.  Make a soft surface over a hard core and you'll get=
 the widest tonal spectrum.  It's great that you can learn this=
 stuff on your own piano.

PS, your last post about your rates tells me that this is now how=
 you are making your living.  Right?

Subject: on needling old upright hammers

Greetings,

             We were told in piano tech school NOT to needle=
 hammers right on the crown. Upon arriving home from 9 months at=
 tech school, I was Jones-ing to refurbish my old upright and=
 needle the hammers in my Yamaha U3, as the tone was harsh on=
 both pianos. 

              Well, I first did the old upright's hammers.=
 Needled the "shoulders of the hammers careful to not go near the=
 crowns. Put the action back in the piano and I heard hardly no=
 change. That horrible harsh, explosive, glassy sound prevailed.=
 So, I decided to slightly needle just a few of the offenders=
 alittle closer to the crown. No difference...tried alittle=
 further into the crowns....To make a long story short, I didn't=
 alleviate the harsh tone till I deeply pounded the needle right=
 in the crowns of the things! What gives?

               I got the results I wanted, namely a more mellow=
 tone, but only when I did exactly what I was told NOT to do.
