<DIV> So if the grooves in the hammers of an old =
upright
are a quarter inch deep and you file and reshape (the customer can't =
afford
new hammers and steaming won't get rid of grooves that deep), then =
do you
just put the action back and leave the blow at 2 inches or more? =
Doesn't that cause bobbling hammers? Doesn't it make the touch =
too
slow because now the hammer is going farther before =
it hits
the string? (The action parts still have the same amount of =
travel if
key height and dip haven't been altered yet, but since all that felt =
is
missing, the hammer "goes farther" before it hits, plus it now lets
off almost 1/2" from the string). Why do the books (and =
most
vertical regulation classes I've attended) say to shim the rail up =
so that
blow is about 1 7/8", then regulate a few keys and see how the =
repetition
and checking turn out, then re-consider blow, etc.?</DIV>
<DIV> Same with grands -- if you don't replace =
hammers,
but rather file & reshape, then you end up having to at least
re-regulate let-off, drop, and backchecking. If you
also turn the capstans up, then you gotta re-regulate =
jack-to-knuckle
position. . . .</DIV>
<DIV> I guess what I'm asking is: If =
you don't
shim the upright hammer rail or turn grand capstans up to get a =
blow
distance of about 1 7/8", plus or minus an eighth or so, =
then
what DO you do -- leave the blow wide? refuse to regulate =
unless they
agree to new hammers? =
