Hello Stephane Collin
If the down bearing measurements are in accordance with manufacturers =
specs, given that the piano has had a re-capped bridge are you sure the =
soundboard crowning is still OK??
Kind regards

Hello Michael.

Yes, I meant varnish on the top of the bridges.  From previous comments, =
it appears that the cosmetic and sealing layer of varnish, even on the =
top of the bridge, should have little or no effect on the sustain of the =
notes, which I verified by scraping that varnish from the top of the =
bridge, and ascertaining that there was no better sustain.  But not all =
agree with this statement, and still, me too, have hard time =
understanding why there is no acoustic difference between with or =
without a coat of varnish.

Any other idea about how to improve sustain ? (I checked for downbearing =
at front and rear of the bridge, checked for lose joints between the =
soundboard and the rim, checked for loose pins in the bridge.  I was =
suggested to replace the soundboard, which I was about to do, and asked =
a quote at the Bechstein factory (anyway, FAR too expensive) and the guy =
there told me he wouldn't do that, pretending they can't beat the =
quality of those old soundboards (but this is another thread).)

  Hello Stephane
  Do you mean there is varnish on the top of the bridges? Where the =
strings touch?=20

  Hi all !

  Marvellous Bechstein model E (2m75) from 1928.
  Fantastic action, but one problem : the trebble notes are VERY short =
(no sustain).  I know that trebble sustain is not the best thing in a =
Bechstein, but here it is obviously dramatic.  The piano has been =
restored 10 years ago, and the bridge apparently recapped.  The =
restorers have put varnish on the whole bridge.  Does anyone know if =
that varnish could be the cause of no sustain in trebble ?  I am =
considering to recap the bridge (though apart from the varnish, it looks =
kind of perfect), and would like to know your expert advice before =
attempting this.
  thanks
