<DIV><FONT face=Arial size=2>Exactly! Roger Jolly convinced me (and =
a whole
class of other techs) of this at one of the PTG conventions. If I recall =
correctly (I'm sure he has an article somewhere on this), he likes to =
have 5 to
7 grams of flange friction (don't quote me on the exact values here). He =
did a
number of demonstrations with varying flange friction. <STRONG><EM>Even =
I could
hear the difference! </EM></STRONG>In fact, he does a lot of his voicing =
with
repinning hammer flanges! He sat down at the piano, played and listened =
to all
the notes in a given section, identified which ones had loose pinning =
(and by
loose, I mean anything less than 5 grams of friction), and then manually =
checked
the friction of the flanges. Any of you who know Roger - well, I don't =
have to
tell you how many he got right!</FONT></DIV>

in heavier
<BR>> tenor and bass hammers, that whatever is gained by the reduced =

wanders <BR>> far to much on hard blows when the pins are this =

Its easy enough <BR>> to hear, and I find it easy to identify loose =

action
ratio, etc.etc.etc.... I <BR>> find it diffucult to swallow that the =

friction of hammer <BR>> flanges that occurs when moving from 5-7 =
swings up
to 8-10 ... or even <BR>> up to 15 for that matter would be able to
contribute significantly to <BR>> power in the first place. The =
hammer
will most certainly be driven to <BR>> its maximum velocity easily =

regardless. On the other hand, <BR>> reduced stability in =

is a significant factor and is easily <BR>> noticed.<BR>> <BR>> =
