Egg on my face. Amazing what you can learn by just rebuilding one piano. =
Amazing
what you did not know while rebuilding it. Amazing what seemed like the =
only way
to do it, later seems so obviously stupid.</FONT></DIV>
<DIV><FONT color=#800080></FONT> </DIV>
<DIV><FONT color=#800080>No, I did not make the notches parallel to =
the top
bridge. Indeed, would seem to be the logical thing to do. Ahh,
hindsight.</FONT></DIV>
<DIV> </DIV>
<DIV>> or did you notch <BR>> perpendicular to the strings?</DIV>
<DIV> </DIV>
<DIV><FONT color=#800080>I'll give you one guess. Let's see how bright =
you
really are!</FONT></DIV>
<DIV> </DIV>
<DIV>> If the top bridge is wood, I'd make a new one <BR>> to =
accommodate the notches in the lower bridge.</DIV>
<DIV> </DIV>
<DIV><FONT color=#800080>It's not wood, but rather just the =
simple ridge on
the cast iron plate with the steel pins. Hey! I just bought a
grinder!!!!!</FONT><BR> <BR>> If I was just replacing a bass =
bridge on a
vertical piano without any other <BR>> extensive work, I'd just bevel =
it like
it was originally.</DIV>
<DIV> </DIV>
<DIV><FONT color=#800080>EXTENSIVE WORK ZONE!</FONT><BR> <BR>> =
>My
question is: would the benefit/difference be audible - would it make =
<BR>>
>for a better piano to the discriminating ear?<BR>> <BR>> With =
the
deviation as a percentage of overall length, and with the erratic =
<BR>>
nature of wrapped strings, it's doubtful. Still, if this happens to be =
the
<BR>> M&H you're putting all that redesign work into, it should =
be as
clean as <BR>> you can make it.</DIV>
<DIV> </DIV>
<DIV><FONT color=#800080>Yes it is the M&H, and yes I want to make =
it as
clean as is (reasonably) possible.</FONT></DIV>
<DIV><FONT color=#800080></FONT> </DIV>
<DIV><FONT color=#800080>Oh shoot. What a dipstick. I actually did =
think to make
the notch the same way as the top termination - but that thought =
withered away -
or maybe it was fogged out by all the other confusion.</FONT></DIV>
<DIV><FONT color=#800080></FONT> </DIV>
<DIV><FONT color=#800080>I recall yesterday when my wife got home she =
asked me
how my day went. I told her all activities had progressed in a positive =
manner.
One of yesterday's activities was notching and pinning the bass bridge. =
Well, I
guess that's why God made lots of maple......</FONT></DIV>
<DIV><FONT color=#800080></FONT> </DIV>
<DIV><FONT color=#800080>Terry Farrell</FONT><BR> <BR>> >I =
should
think the difference would be much the same as on a grand that <BR>> =
>has
agraffes in the bass and the bicord area of the bass bridge is at a =
<BR>>
>fair angle to the strings and is upgraded from a continuous single =
bevel
<BR>> >to proper notching. Does this upgrade on the small grand =
result in
an <BR>> >audible improvement?<BR>> ><BR>> >Terry
Farrell<BR>> <BR>> If the agraffe is already parallel to the =
bevel,
notching and repositioning <BR>> the agraffe so they will both be
perpendicular to the string won't make any <BR>> real =
difference.<BR>>
