<DIV><FONT size=4>Bill and List,</FONT></DIV>
<DIV><FONT size=4>Many years ago, I rebuilt a Kimball, 6'?" Grand. It =
had tuning
pin bushings, which were larger than standard and they were made out of
laminated maple! I duplicated this when I redid the piano. It was a =
dream to
tune. I might add, I used pin driving fluid, so that the threads of the =
t. pins
would not "ream" the bushings. At the same time, another top quality =
rebuilder,
friend of mine, did another Kimball with the same configuration. He =
opted to put
standard plate bushings in. That piano was, and still is, a bear to =
tune! My
conclusion, then and now, is that if the proper material is used for =
plate
bushings, (NOT endgrain, non-descript wood), they will enhance the =
t.pin
stability in it's axis and tuneability will be ensured.</FONT></DIV>
<DIV><FONT size=4>One thing that should be noted, is that tuning pin =
bushings
change the lines of force within the frame/plate/pinblock structure. If =
one is
to draw a side view of a piano structure, (ie plate w/pin block, tuning =
pin and
string, etc., then draw the lines of force and the pivots therein, one =
will find
that, with a plate bushing the direct line of force is directly into the =
plate
and not in the pin block. Without the plate bushing the direct line of =
force is
directly into the pin block! It must be assumed that in this example, =
the tuning
pin MUST be tight in the plate and around the tuning pin. Of course, the =
standard plate bushing does not meet this criteria. </FONT></DIV>
<DIV><FONT size=4>Just some more food for thought. And yes, Del, I =
know you
don't agree. Methinks too much brainwashing from your days at Baldwin. =
[grin]
:-)</FONT></DIV>
