Yes, Holmes, it was I!!!  Oh, I knew the day would come when I would be =
found out.  But you see, I have only been masquerading as a mild =
mannered piano technician.  In reality,  my true identity =
is.........(scream).......(scuffle).........(thud)..........(door =
slams)...........

  So it's you who did that!   ;-]   The problem, imho, with the center =
pin/nail is you still have the top/bottom of the pitman moving slightly =
against the lever & tray and potential noise.  The 1/2" dowel with a 3/4 =
inch punching glued to each end and fitting into a 3/4 inch recess =
(forstner bit) eliminates that remaining friction.   The hole in the =
keybed is is about a 1 inch hole (forstner bit again).   The archives =
has lots of stuff on this...

  Hi list,

  If you ever want to find out how much changes in the field of piano =
technology, just take a nice long leave.  When you come back you will =
find that some things which were very "fashionable" have gone by the =
wayside, or worse, find out that a one time favored method or whatever =
is actually considered harmful.  (Sort of makes me think of a very funny =
scene in Woody Allen's film, Sleeper.)

  Anyway, speaking of damper systems and trapwork--when I first started =
in the business, I was told by John Ford (!), to remove the pitman, =
drill a little hole in the end to insert a center pin (a small bit of =
the sharp side protruding).  This would keep the pitman in place and =
eliminate noise.  Since I've come back to work, I've read that folks =
make the hole in the keybed larger.  So, is it a toss up, or did I =
horribly damage all those pianos where I inserted the center pin?=20


  Anxiously awaiting enlightenment!    :-)
