Keytop Mat'l, thickness

[Jon Page]

---------------------- multipart/alternative attachment
Of course the cost of ivory replacement is commensurate with the value
of the piano or at least the 'heir loom' coefficient.  A beautifully replaced
ivory keyboard is truly held in the eye of the 'beholder'.

An understanding of action geometry needs to be understood before replacing
keytops with thicker plastic replacements. Since the plastic replacements 
available
are thicker than the ivory which they replaced, planing the 'natural' 
keystick to
maintain appropriate sharp height has to be considered.

It's so easy to be complaisant, strive for perfection.
