<DIV><FONT face="Comic Sans MS" color=#000080>This piano may well =
have at least
part of two separate problems. First, there may be a mounting problem as =
witnesses by the tightening of the attachment screws. If there is any =
gap at all
between the termination piece and the plate--especially under the capo =
tastro
bar--there will be a potential for a buzz. As I understand things, this =
is one
reason why the change was made from multiple unison pieces to individual =
unison
string termination pieces. The only way to tell for sure will be to =
remove the
section, check the surfaces and bed the section tightly using a steel or =
brass
filled epoxy. I would follow Roger's advice and have the string =
termination bars
smoothed and hardened as well. </FONT></DIV>
<DIV><FONT face="Comic Sans MS" color=#000080></FONT> </DIV>
<DIV><FONT face="Comic Sans MS" color=#000080>The second problem is =
one which
has always plagued this design. The string termination angles are too =
shallow
and front duplex string lengths are too long to provide efficient string =
termination. On the individual termination pieces I have successfully =
ground off
the front (toward the tuning pins) bearing bar and replaced it with a =
brass
half-round. So far this has proven to be a permanent fix. The following =
drawing,
which I hope makes it through the ether, should illustrate:</FONT></DIV>

<DIV><FONT face="Comic Sans MS" color=#000080>This shows the =

<DIV>> He feels sqeamish about it, lacking the old devil may <BR>> =

spirit, and wondering what happens if he gets it apart and doesn't find =
<BR>>
anything. How can he charge for his time without assurance it will =

<BR>> productive. The age old problem. (My own solution is to eat the =
time
and call it <BR>> educational expense). </DIV>

<DIV><FONT face="Comic Sans MS" color=#000080>Somehow I don't ever =

So
anyway, I thought I'd throw the problem before this forum of wise, =
<BR>>
experienced, skilled pandits in hopes that someone will say, "Hey, I had =
just
that <BR>> same problem, and this is how I solved it," so as to ease =
my poor
colleague's <BR>> nerves.<BR></DIV>
<DIV><FONT face="Comic Sans MS" color=#000080>Well, it's a common =
enough problem
with these pianos. But the symptoms can be relieved per Roger's =
suggestions or
it can be permanently solved per the above. It all depends on how much =
the
client is willing to pay for the solution.</FONT></DIV>
