    I always clamp the key frame to make sure it is in contact with the =

    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.
