Soundboard backposts ??

[Richard Brekne]

Hi list..

Got into a discussion today with another piano tech which prompted me to
put the following question to you experts out there.

Given an old beater with a flat soundboard, perhaps a bit of negative
crown... What would the effect be of glueing in wood pieces between the
ribs and the back frame beams to force and hold the soundboard into a
artificial crown ??

sounds off the wall, I know... but I am curious to hear your responses.
