Fred, Rob,

I think you are both making very good points here.  An elaboration:

I recently was called to get a D ready for a performance.  It was a C&A 
piano, relatively newly delivered, on which the regular technician had 
spent a very great deal of time making modifications.

Among these was to lower the overall damper setup to where no combination 
of pedal and/or key would give much more than 2mm lift.  Needless to say, 
the pianos had little above mf that was not pretty dramatically affected by 
this "performance improving" change.  No, the trichords had not been 
trimmed, mores the pity.

The only way to "compensate" was to essentially leave alone the glassy, 
over hard hammers so that they could, so some degree or other "blow by" the 
dampers.  A most mediocre "fix", to be sure, but there was not time to 
reregulate things.  In order to buy a little bit of dynamic range for the 
poor pianist, I lightly touched up some of the more surface voicing, and 
opened up the lower end a bit - a poor trick, but all that was available.

Having now seen a number of instruments which have had their actions 
modified in various ways, I would offer two most urgent suggestions:

First, consider that any modifications that we do are essentially 
"point-in-time" types of operations.  I have never been massively enamored 
of the need for a striking hammer to be precisely at thus-and-so an 
angle.  The very first time you shape the hammers again, those 
relationships change.  Act accordingly.  Put another way, is the time and 
effort which you put into a given piece of work going to yield some 
tangible musical result in excess of the increase of dollars in your pocket?

Second, more important in some ways than the first, is that, having decided 
that a certain instrument will truly benefit from a certain 
procedure...follow the procedure through.  Do not start at some 
hypothetical step 50 of a 75 step procedure and expect things to work very 
well, if at all.  The instrument described above had lead weights inserted 
into the moldings of many of the as-yet-unshapen, quite asymetrical 
hammers...which were hung on shanks and flanges which were most oddly 
pinned...you get the idea.  Very poor.

Best.

Horace
