Why do we keep talking about doing this kind of semi-heroic stuff when it is
a warranty issue?  Six figures was spent to get this thing and the company
that got the 6 figures out to make a 6 figure piano out of it.

String Height minus Hammer Bore equals Shank Center Pin Height. We use
laminated shim stock that we get from the local hobby store. Realize that
just raising the pin height MIGHT work, but consider the arc of the hammer
blow. You could end up with the hammer over centering if you simply raise
the feet under the hammer flange pins. You need to imagine the pin in space
and rotate the stack around it so that the stike point ends up at ninety
degrees to the string. It might not be that now. Usually this means shimming
the front foot slightly as well. Best of luck Andrew.

Yes, mea culpa.  Wasn't really thinking the numbers...most likely 2"+

Andrew, 

 

Not sure what you mean by this ("greater then 1" blow distance").  Did you
mean greater than 2" (since it sounds like the strings are too high)?

The school whose Steinways I service is not satisfied with the dealer's
warranty fix (greater then 1" blow distance). They are requesting that the
piano be made to play like it should which will require shimming the stack
so it is within reach of the strings (>1/4" between fully backed out
drop-screws and pinblock). 
 
Has anyone done this? What was the scope of work required? What is a
reasonable amount of time to complete the work? 
 
Thanks 
Andrew Anderson
