Kawai problem

[James Grebe]

Hi All,
This afternoon I tuned a Kawai GE-1 with plastic hammer shank flanges.
Several notes in the mid treble had clicks.  I isolated the noise down the
the center bushing.  The swings of the hammer on the clicking ones and
non-clicking one were about 7-8.  Is it better to put on new plastic
flanges, thinking that the center pin is OK in the bushing or just install a
larger center pin in the original plastic flange and ream the bushing as
necessary?  Why do they make the plastic parts the same color as wood, just
to trick us?
