<DIV><FONT size=2>I wasn't so much thinking about 14lb vs 16 lb. =
I realize
the difference hammer to hammer is minimal. I was more thinking =
about
moulding, size, etc.. I assume the hammer weight is less =
significant than
a grand because of the hammer's relative position to the lever and the =
fact that
it travels horizontally rather than vertically. In a grand the
relationship is generally 5 or 6:1. I was wondering if there is =
such a
general ratio for an upright or if it is even significant. As I =
suspected,
it seems relatively insignificant.</FONT></DIV>

that is the weight of an entire sheet of felt, out of which 6 or 8 =
