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.
