<DIV><FONT face=Arial>Hi Dave,</FONT></DIV>
<DIV><FONT face=Arial>This has been an observation of mine =
also.</FONT></DIV>
<DIV><FONT face=Arial>The steep sharp angle seems to be of factory =
orgin but
could have been worsened by slight tapping in of the pins. The wire =
breaks due
to the added torque of the wire riding up on the coil.Makes that string =
harder
to tune also.</FONT></DIV>
<DIV><FONT face=Arial>That result of tapping pins, caused me to use CA =
glue as
my first remedy and only tap pins if there were only a few, and those =
few were
not on the steep decline. <g></FONT></DIV>

breakage</DIV>

<P>

<DIV>
<DIV>List:</DIV>
<DIV> </DIV>
<DIV>I just tuned a Baldwin acrosonic that by S/N was 15 years old, =
but it
appeared to be older.</DIV>
<DIV>My question revolves around the attached picture ( as best I =
could
draw the problem ).</DIV>
<DIV>The strings A2, A#2, G2, G#2, F2,F#2 and C3 all broke when =
doing an
80-100 cent pitch raise.</DIV>
<DIV>I warned the owner that I could tune it to less than A440 to help =
reduce
string breakage but she wanted it at A440 so she could play with other =
instruments.</DIV>
<DIV> </DIV>
<DIV>All the strings were on the bottom row of tuning pins, =
which creates
a steeper angle to the Vbar.</DIV>
<DIV>The angle to the Vbar was so great, that the last coil on the pin =
was
trying to cut across the previous adjacent coil on the tuning =
pin. ( see
pic ).</DIV>
<DIV>It appeared to me THAT is why the strings broke, each one =
right at
the pin coil.</DIV>
<DIV>It did NOT appear that the pins were pounded in, creating a =
steeper
angle.</DIV>
<DIV> </DIV>
<DIV>My question is:</DIV>
<DIV>Is this normal pin / string coil configuration for =
acrosonics?</DIV>
<DIV>has anyone seen this before, and what might the problem and fix =
be?</DIV>
<DIV>I'm sure someone on here knows the answer !</DIV>
<DIV> </DIV>
<DIV>Thanks much</DIV>
