Recrowning the soundboard

Forgive me for all capping, I think that the soundboard is important.
Unless someone has driven a truck through the old soundboard, I would not
replace an old one with a new one.  The exception is flood damage where it
sat wet long enough to get major reverse crown.  Then I would keep the old
board only if I could get it out of the piano and get all the ribs off
without major damage.

If you allow me this observation.  You would never consider restoring a 280
year old Stradivarius violin by tossing out the soundboard and replacing it,
would you?  But we would with a piano much younger?

Recrowning the soundboard is not a procedure that can be written in an
email.  I have been writing on a booklet for some time that details such
work.  I may have it available on my soon-to-be-put-up website in a few
months.  It involves putting the soundboard back under the pressure it had
on it when new.  If you think of the top and bottom surfaces of the
soundboard as two parallel lines starting and ending at the same points, you
will realize that if the top line is made longer it pulls the bottom line
into an arc.  the ends stay together and do not move.  This is the whole
principal.  Art Reblitz does the same procedure that I do.  Perhaps he will
also write a book about it.  It makes the difference between an old piano
sounding like an old piano after restringing and that same piano sounding
like a new one but with an extra roundness or darkness of tone.  It also
prevents soundboard shims opening up from cracking down one side a few years
later.
