Steinway action noise

Did the other tech remove/replace the underfelt on the hammer-flange rail? If so, that would decrease the spread a tad.

OK folks,
I finally have some pics that might prove helpful. I may have to do multiple
emails though so it passes through the filters in a timely fashion. Here's
the first showing direct manipulation of the wippen. Note where the drop
screw contacts the leather. The jack tip is contacting the hammer flange in
between the hammer shank ears.

More to follow.

(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.
