<DIV><FONT color=#000000 size=2>Well, being a born dinker arounder, =
I have tried
most things in this regard. The only thing I have personally found =
usefull is a
bit of finger pressure down and sideways on a string right at the =
forward bridge
pin. This works quite often really for very slight adjustments in pitch. =
I have
been left suspecting that there is something about how the string meets =
the
bridge and pin that doesnt really get dealt with by regular string =
seating at
the bridge and have it on my mind to play around a bit with different
possibilites for bridge string termination, but thats another story...

am
studying <U>supplamental techniques to fine tune unisons</U>... that =
is, I
am researching and testing methods other than hammer technique, to =
make
small adjustments to solid wire. Thank-you Graeme Harvey, Susan =
Kline and
Joe & Peny Goss, for your =
help.<BR> I am
specificly collecting technicians experiences who use use wooden, =
brass, or
other tools, to push or massage the wire, in order to make fine =
pitch
adjustments. If you have some positive results, and use a tool =
to this
end (other that tuning hammer technique) in your work, please =
post me
at my personal e-mail address. I will collect the info and =
report
updates and progress to the list. <BR> The =
goal of
the research, is to see if there is a reliable and predictable =
technique, to
make fine pitch (lowering) adjustment in a solid wire unison, where =
hammer
technique is difficult, or not accurate enough.
<BR> The premise and background of this study =
is as
follows: (Unison checks from an arual technicians
perspective...)<BR> We get the unison as close as possible with =
hammer
technique. Then, we compare the pitches of the three wires, =
with 3rds.
6ths. 10ths. etc. If one of the wire is found to be slightly =
sharp,
(and hammer technique too course), we lower the pitch using the =
tool.
<BR> These techniques can also be used to =
lower
single wire (outside wires being muted) pitches, as in strip-muted =
octave
setting, or in making fine adjustments in setting the
temperment.<BR><BR>Thanks for your encouragment.<BR><BR>Dan =
