Backcheck noise

[David Love]

Been through that already.  There was some clicking that was resolved by
repining and changing some of the flanges.  This is something different.
The noise definitely disappears when you push the backcheck backward so that
it doesn't engage the hammer tail.  It's not an impact noise but a noise
which follows very closely behind.

Hmm,  well, these new Steinways are equipped with the perma-free thinking in

their hammer flanges.  Maybe you could repin a couple of these shanks to
have 
maybe 3 grams of resistance in them and see if that lowers the noise. I
would 
throw in the balancier pinning as something to check, too.
