Decreasing

while UW
increases. Those numbers you have sound fine (for some pianists!). =
Although I am
currently revising my whole take on this issue. I am working with a =
faculty
pianist, a great pianist who loves her home Kawai KG-6. She has always =
said to
me that she likes a heavy piano. Until last week when I finally went to =
her
house to tune it (a good friend of mine is her regular tech) I had =
always
thought that I needed to interpret what she meant by heavy. "Because, =
hell,
nobody likes a heavy action!" Wrong. She loves her piano and it weighs =
off
generally in the 60-70 range with upweights generally in the 30-35 =
range.
So.... as I said I am revisiting the generally accepted numbers. I think =
that I
would rather have a bit higher DW and UW numbers if by doing so I could =
use less
lead in the keys to achieve less inertia in the action. Always a trade
off.</FONT></SPAN></DIV>

<DIV>I've just done complete down and up weight measurement on the new =
D. From
C1 - F2, the down weight is between 52 and 55 grams. The rest is =
between 47
and 50, with a few 45's and 46's in the 7th octave. Upweight is =
generally
between 27 and 30 grams, with some as low as 25 and a couple as high =
as 34.
</DIV>
<DIV> </DIV>
<DIV>The Piano Action Handbook says down should be 51-52 in the bass
graduating to 47 in the treble, with up weights at 20. After Christmas =
I'm
going to lube all centers and check for pinning. Hopefully I'll get =
better
upweight measurements. Is this about what you guys are going for? BTW, =
is TW
the difference between down and up, or am I missing something in the
calculation?</DIV>
