[pianotech] New piano key?

[Dean May]

Dittos from this corner as well. I tuned a fairly new Steinway upr model K,
maybe 10 years old. Customer said it was a Hamburg Steinway, but who knows.
Any rate, they love the piano, I suspect mostly because it is a Hamburg
Steinway. I hated it. Though it sounded pretty nice, it played like a Mack
truck. When depressing the key, it was starkly obvious when the damper
started lifting, the spring tension was huge. I asked if they were happy
with the touch and they said yes, so I made no suggestions to improve it.
Also on that piano, the key bushing slop was awful. Could have been the
previous tech overeasing, or the owner's son does play a lot they say, but
it seemed like a very unusual amount of wear to me. Beautiful piano, nice
tone, awful to play. I would have loved easing those damper springs just to
see what a difference it would make, but you know the saying, no good deed
will go unpunished. Back away slowly.

Dittos to Pauls comments.  We did a mass installation at a school. We
weakened all the damper springs in Kawai, Yamaha and the new Pramberger
uprights.  It makes a massive difference in touch and the dampers still work
just fine.  Its obvious that no attempt was made in any of these to regulate
spring tension.  Probably too expensive

Hi, Seles:
I'm not sure about this model, as I haven't seen it, but if I were to guess,

it's the damper springs.  It's an upright piano, right?  Yamaha pianos have
the 
spring-and-loop arrangement on the hammer butts, so it's not likely to have 
overly strong springs there.  Unless there's too much friction in the key
(not 
likely, or it would be sluggish).  So, what's left?  I've found on many
pianos 
that the damper springs are too strong.  Strong damper springs are also
likely 
to cause hammer bobbling on a light blow.  If that's a tendency, more than 
likely it's the spring tension.  You can use a Hart spring tool to bend them

backwards and weaken those springs a bit.
Good luck.
