[pianotech] regulation "sweet" spot

[B214cm at aol.com]

It could be several things but I'd look at  the key dip spec because  it 
sounds like you're not getting enough after touch on the problematic  offenders. 
Key height and dip should be set before any regulation begins.

Hello  again,

I have installed new hammers on a baldwin grand and am now  doing the 
regulation.  I have followed all recommended steps and things  are going smoothly.  
(This is my first full grand regulation).  I am  having some trouble on a few 
notes not finding that "sweet" spot of let-off to  drop ratio or point.  I am 
using a let-off rack set to baldwin spec of 1"  7/8" and have levelled the 
hammers for a proper blow distance.  The  majority of the notes are good and 
behave as expected. i.e. a slow rise of  hammer to a 1/16" below string strike with 
a 1/8" drop with that little bump  (what I call the sweet spot) in the feel 
of the key as you play.  Granted  on the good ones some of the "bumps" are 
stronger than others but on some it  is very weak or on the bad notes it is not 
present at all.   

The questions I have are:

1.  What should I do  when I can not get the two Let off and drop to 
reconcile?  (good rise vs.  too much drop or poor rise with that magic bump in the  
feel)

2.  If I get the regulation button turned so low that  there is no more turn 
left and I am not getting good results what should I do  after starting back 
at beginning of that notes regulation?

This  action is about 30 years old and to my knowledge has never had any  
regulation.  Any help or suggested reading would be appreciated.  I  have all 
Pace resources and Reblitz but recommended order of regulation is not  helping 
with the reality of regulation problems.

Thanks again to  all who help so willingly,

Steven
