<DIV><FONT face=Arial>Went to service an 18-year-old Samick console =
this morning
- SU-105, #619893. The two right wound bass strings on C#3 and D3 =
(treble-most
on bass bridge) were broke at the coil. I spliced them with 0.034 wire =
(same as
original core). </FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Bass was 40 cents flat, so I started a pitch =
raise at A0
(going with about an 8-cent overpull). During the pitch raise, the right =
strings
of B2, C3 and C#3 (again) broke right where the wire from the V-bar =
starts into
the coil. Started figuring that maybe the scaling was just too darn =
close to the
breaking point.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Then I noticed that the V-bar is quite tall and =
the bottom
row of tuning pins are at right angles to the plate - meaning that the =
string,
between the V-bar and the tuning pin, approaches the tuning pin at quite =
an
acute angle (guess - 70 or 80 degrees? - it's really quite an =
angle) rather
than at a right angle. So much so that on adjacent pins, I can see that =
the
string is starting to wind over the coil.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>So what I think I have here is perhaps a scaling =
that is
closer to breaking point than need be (maybe) and tuning pins that are =
drilled
at an inappropriate angle (definitely) - they should be leaning back 10 =
or 20
degrees so that the string meets it at 90 degrees or so.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>So, my question is what is the best and/or most =
cost
efficient remedy? I can install strings with a thicker core - but =
obviously that
will affect scaling and hence tone (and this piano sounds pretty good =
for what
it is - or isn't). I suspect the only "real" solution would be to plug =
through
the plate and redrill the tuning pin holes (yes, of course, what it =
really needs
is a new pinblock - or better yet, a new piano!). But YIKES, that seems =
extreme.
But then again, I really can't imagine what else to do.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Maybe pound in a longer tuning pin and leave the =
coil a
half-inch off the plate? Seems kinda goofy (but simple).</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Any bright ideas out there?</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Roger? Warranty?</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>I posted this to the list also because I know =
this is not
the only piano where this problem exists.</FONT></DIV>
