basic regulating question

[A440A at aol.com]

<< What I don´t understand: how do you change blow for a single key without 
altering the blow of the neighbour key? And does that not result in an unequal 
hammer line which looks not so fine? I know the trick to make an even hammer 
line by pressing the rest rail felt with a hot steel. >>

Mea culpa,  this procedure is what I use on grands.  
        On uprights, I suppose a small shim behind the rest felt would allow 
the same thing.  Yes, there is a slight erratic look to the hammerline on a 
grand that is regulated this way, but when the pianist is in the middle of a 
Chopin  screamer,  the look of the hammerline is far less important than a 
keyboard that is as consistant in feel as possible. 
Regards.
