MessageThanks Dale. The thought of using shims had occurred to me, but =
had not tried it out yet. Your additional procedure of doing a few dips =
accurately in the piano, and then replicating them on the bench should =
indeed eliminate some uncertainty and get you pretty darn close. Thanks =
for the tip.

I think sometimes the difference between folks that do all their =
leveling in the home and those that prefer to do it in the shop, is that =
some techs have a lot of high-performance pianos to maintain and their =
leveling consists of perfecting a not-so-horrible keyboard. I like the =
shop because almost all my leveling jobs are these =
never-been-leveled-in-82-years jobs plus they need major regulation, =
minor repairs, file off a half-inch of hammer felt, etc. So, I think =
shop leveling does have its place.

  Carl & Terry,
  Bed the keyframe, adjust the glides and set samples of dip in the =
piano before you bring the keyboard into the shop. Then when you clamp =
the keyframe to your bench, use shims to duplicate the dip on your =
samples. Don't adjust the glides in the shop. When you take the keyboard =
back you should be pretty accurate in the piano and just have touchup to =
do.
  Best,
  Dale

      Sure sounds like something is moving.  If you find out just what, =
I'd like
      to know.

      I always clamp the key frame to make sure it is in contact with =
the bench.
      Sometimes even in the middle of the front rail.  I haven't =
actually leveled
      that many keys.  It's more fun to make tools than to use them.  =
I'm only
      half joking when I say maybe you should use go bars all over the =
frame.

      The problem, as someone suggested, in leveling in the piano, is =
that there
      is no room to install the weights on the backchecks, the stack =
isn't on
      (that may affect the height) and you have to sit so low that it is
      uncomfortable.

      I'm assuming you use the weights hanging off the backchecks.  They =
are
      probably heavier than the stack.  All these small variables add =
up, but I
      still feel doing at least the major leveling on the bench is more
      productive.  Especially when you are refelting the whole keybed.

      Let me know if you come up with any ideas as to why that is =
happening.

    I would like to mention something about the attachment of the =
clip-on lead weights.
    They should not be 'hung'_off_the back of the backcheck. This has a =
tendency to lift
    the front of the key higher than the weight of the action would, =
giving it a false height.

    They should be 'hung'_on_the front side of the backcheck. The action =
will fit better
    into the action cavity.
