As always, Dale and David, thanks for your insight.  =20

I understand the hammer weight thing.  Let me add that this rebuilder =
found that the 17 mm provided a bit too much leverage for most projects =
and wished New York produced a shank with a 16.5 mm distance.

By any chance (though I know there are always exceptions) would 16.5 =
tend to work better in the earlier S&S pianos?=20
  =20
Are Ronsen Wurzen hammers generally lighter than NY S&S?



Thanks,

Barbara Richmond

  I would use Renner knuckles.  The size will depend on the location.  =
The farther down the balancier, the bigger they tend to be.  Choice of =
16.5 over 17 should depend on the overall leverage as it relates to the =
hammer weight, not a personal preference. =20

  Hey Dale Erwin (and all),

  =20

  Long time ago we were talking about moving/replacing knuckles.   I'm =
ready--um.... well, I have a friend who has all the equipment, anyway.  =
;-) =20

  =20

  So, I'm ready to order knuckles.  One time you recommended the ones by =
Tokiwa.  I looked in the Pianotek catalog and saw that the Tokiwa =
knuckles only come in 10mm diameter.   I guess you wouldn't use them if =
it was a problem, but have you ever run into a case where that size just =
won't work regulation wise? =20

  =20

  I have a couple sets of shanks and flanges downstairs and I haven't =
measured their width yet, so maybe I'm jumping the gun.   Perhaps I =
should just wait until I have the pianos in hand and can test different =
shanks & knuckles.

  =20

  I also had a private e-mail from someone who said he doesn't like 17 =
mm knuckle distance, but prefers 16.5.  After using the 17 mm knuckle =
distance on the Big, dead hall D and having to set the key dip pretty =
deep (but no complaints from pianists), I am wondering if 16.5 mm =
distance and a bigger knuckle (or not) would be better than 17 mm. =20

  =20

  The pianos that will probably get these sets of shanks and flanges are =
1920s (or give or take a few years) Steinways.  One B and the other an =
L.    I'd like to just have these sets ready and waiting for convenience =
sake and also, because my friend with the equipment is available now. =20

  =20

  What would you do?

  Thanks,
