The very rigid wire tends to create key noise, from the B/R =
hole/pin.
Just a slight hint of chucking and the key will clatter. </DIV>
<DIV> </DIV>
<DIV><FONT face=Arial color=#000080 size=2> I have =
never heard
"noise from the balance rail/ hole/pin" ..caused by the back check =
wire!
If you hear "chucking" consider easing the keys </FONT></DIV>
<DIV><FONT face=Arial color=#000080 size=2><EM><U>slightly =
</U></EM>at the
balance rail.</FONT></DIV>
<DIV><FONT face=Arial color=#000080 size=2></FONT> </DIV>
<DIV> Slightly flexible and the check helps to absorb that noise
energy. I think Wim mentioned, better checking from thicker =
wire.</DIV>
<DIV> </DIV>
<DIV><FONT face=Arial color=#0000ff size=2>Flexible, in any type =
of playing,
will cause ""uneven check"". Wim is correct imho!</FONT></DIV>
<DIV><FONT face=Arial color=#0000ff size=2></FONT> </DIV>
<DIV> This is not so. The slight flexibility helps trap =
the
tail. Like all things in piano work there is a window for the
parameter.</DIV>
<DIV> </DIV>
<DIV><FONT face=Arial color=#0000ff size=2>There is always a =
window, in
tuning..and voicing. A very..very..very small window when it involves
regulation.</FONT></DIV>
<DIV><FONT face=Arial color=#0000ff size=2> </FONT></DIV>
<DIV> Too flexible unstable regulation, too stiff, then too much =
noise. </DIV>
<DIV> </DIV>
<DIV><FONT face=Arial color=#0000ff size=2>Yes to the first =
part. Too stiff,
in my experiance..great check. The noise?? Back to the balance rail. =
Tell me
the relationship between the back check wire and the "uneased key at =
the
balance rail" I would love to learn!</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV> Checking is more of a function of leather/felt =
quality, and
tail geometry, plus a little flex. <G></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial color=#0000ff size=2>Correct....but...you =
fill in the
