<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? --David =
