action ratios

[David Love]

Before you start deep needling up there, you might just put on another
hammer somewhere and see if the sound is different.  Or if you have any
extra Abels from the set you just put on, put on one and have at it without
worry of diminishing the power.  I tend to use Renner on Bechsteins but I
have used Abel hammers.  When replacing hammers, I try and put on some
samples to see what I like, and what the customer likes.  A couple of
hammers won't tell the whole story, but it will give you a clue.

Thank you very much, David.

I'll try the 11:30 12:30 parallel to molding stitching.  (I never done
this )
What type of hammers would you recommand ?  Renner blue ? (but I believe
this is for us market only, isn't it ?)

| I hesitate to make voicing suggestions from afar, but I have had similar
| problems with Abel hammers.  If the piano jumps from pp to mf with little
in
| between and the piano sounds open and is not breaking up at ff levels then
| that suggests to me that the outer layers of felt in the 10-11:30 and
| 12:30 - 2:00 range need some needling to about 4-5 mm tapering down as you
| approach the crown.  Abel hammers sometimes benefit from a couple of
deeper
| stitches parallel to the molding in the 11:30 and 12:30 area also.  But I
| make these suggestions with some reluctance because I don't know if I
would
| interpret what I would be hearing the same as you.  I can say that in my
| experience, you have to work a little harder to get those hammers to open
up
| at various levels.

| Hi David.
|
| I use Abel hammers (no underfelt, referred to as Bechstein model, quite
| hard).
| I do much low shoulders deep needling to open up the tone and avoid
| distorsions at forte level.  Then I even out volumes at different
dynamics,
| and end up with very light blow colour evening (with sugar coating).
| I always get the sound good (enough for me), but I always end up with
| something musically difficult to control.  I ended up thinking this is a
| specific Bechstein desing problem, as the Steinways I restored never rose
| this problem.  I am probably wrong, am I not ?
| I try to achieve 10 mm key dip, and 47 mm blow distance.
| Following my experience, needling more than what I do would result in loss
| of power at forte playing, and reduction of colour shades (which again
seem
| to be more easily achieved in Steinway pianos).
| Any further idea ?
|
| Thanks for spending time.
|
| Stéphane Collin.

|
| | My first reaction is to say that I would look at it as a voicing
problem.
| | What kind of hammers are you using?

| | Hi Richard, David, Bill, etc.
| |
| | I've been following the thread with much interest.
| | May I ask an innocent but pragmatic question (I think related to this
| topic)
| | ?
| | More than often, I encounter this problem when rebuilding Bechstein
pianos
| :
| | I get the sound right, I get the touch feel ok, but the whole instrument
| | always happens to be difficult to control, as the dynamic output
switches
| | too quickly from PP to mF (I mean :  the dynamic shades are not
| progressive
| | enough.  Very soft playing is fantastic, very loud also, but
progressively
| | crossing from soft to loud happens to be difficult to control, as sound
| gets
| | loud too quickly, which is musically not desirable at all).
| | How would you all cure this problem ?
| |
| | Thanks to all for great expertise.
| |
| | Stéphane Collin.
