Steinway action noise

[Greg Newell]

David,

Good advice all. I'll have more time to play with it this weekend. I hope.
Anyway many thanks to you and to Ed and to everyone else for all your help.
Much appreciated.

All the best,
Greg

Front, back, I guess I wasn't too clear.  I suppose proximal and distal is a
more accurate way to describe things if I only knew what they meant :-).  

I wonder if they aren't Hamburg parts from Steinway.  The current Renner
doesn't have the buckskin wrap but it's possible that the ones that Steinway
provides do.  It's been awhile since I order them that way.  

The rails may not be in the right place (wouldn't be the first time) which
would explain why you are having trouble with parts alignment using the
Renner kit as well.  I would still try to work the spread out to 113 mm (via
the wippen flange) on one sample and see where the drop screw falls on the
balancier leather and while you're at it also whether the jack, when aligned
properly to the knuckle, aligns at 90 degrees to the shank.  

One other consideration, it seems to me that a hard blow shouldn't cause
that much difference in the jack escapement unless the front rail punching
is too soft.  Consider a firmer punching (maybe Wurzen felt from Jurgen) and
see what happens.

David,
	Ok, That makes more sense. I was thinking of the front as the front
of the action ... key area. I suspect that I might need to shim both the
hammer side of the hammer flanges and the top of the wippen flanges. That
should give enough clearance but how did it ever get this way in the first
place? Is it rotation of the rails prior to soldering or is the spread
between the rails wrong or what? Wrong parts? If so why doesn't anything
from the Renner parts kit work? Weird!

No.  You shim the flange on the hammer side which will raise the flange away
from the jack.

If I understand you correctly you mean to tilt the flange back toward the
hammer? Won't that make the jack contact even earlier? I know I'm missing
something here.

You could also remove the flanges and shim the front of the hammer flange
rail with a strip or two of heavy paper packing tape.

(ahem),  Steinway offers a variety of parts,and there have been stock parts 
sent me that certainly did not fit.  The jack/hammerflange contact is not 
unheard of.  Your problem is more likely in the rails than the parts.  If
the 
hammerflange rail is just slightly rotated, there is interference.  The pin
to pin 
distance may be correct, but the flange will be out of place.  Ususally when

this happens, the drop screws are turned all the way up.  If no new parts
are 
available, you can often stop the problem by removing the proximal half of
the 
jack, near the top.
