Hi Dave,
Vanda King is the only place I found a Schwanter wippen section. Schaff as far as I can tell doesn't have them. So I wonder where she's gettting them from. Jurgen has the damper felts I need, the three wedge bass bi chord. I'm still waiting to hear from them on their price list. Do you guys use Schaff for string duplicating also? thanks

Subject: [pianotech] Weickert Felt by ROnsen
Hi All
Perhaps this has been discussed here since April when I took my leave of abscence. So... Just a quick comment to say that the final development of Weickert felt has been dialed in closely By Wurzen Felt co/Jack Brand. Over the past 1 & 1/2 years Jack Brand,Ray Negron at Ronsen, myself have worked hard at beta testing for feedback and the latest batch of felt is getting good reveiws. I've heard some very positive comments from Star Taylor, & Darrel Fandrich. I think Starr has used them in a Stwy B and a Yamaha of some kind.
Any body else out there with objective or subjective feedback. I'm just working up a BB Mason but I haven't heard them yet.
Thanks

I'd be interested in what people are finding that they have to do to
prepare them for any kind of fine voicing. Are there sections that needs more
hardening/needling? If hardening, what chemicals are working best? How much? If
needling in any general sense, where and how much?

Hi Dale, Paul,
Dale, as you know, we recently installed a set of Weickerts on a 9' Henry F. Miller. Very nice hammers - the whole package. Used acrylic/acetone in the top two octaves to bring them up to the same level as the rest of the piano. Not much more than "break-in fluid," really. And, honestly, less than 30 minutes needling. Most of that time spent just checking to be sure I wasn't overlooking something. Very little actual needling. The acrylic/acetone worked very well in terms of bringing the tone up and matching the overall tonal palette of the other hammers. Very warm sounding hammers. Great fundamental, and a really penetrating sound. "Out of the box" type of tone, and very nice. More like a Shigeru Kawai than a Steinway it that means anything to anyone.
Client is very pleased.

Subject: [pianotech] regulating S&S (ex-) reproducer actions
I'm told by an esteemed rebuilder colleague that the
Steinway reproducer actions don't regulate quite the same as the
"regular" actions because the longer keys change the action
geometry. He says he usually has to compromise something in the
regulation for better playability.
I regulated one (player system removed) after installing new
hammers & shanks and can't quite get rid of bobbling hammers.
Or, not so much bobbling as hammers not wanting to check on a
soft blow.
The key height is as high as it can be without interference
from the fallboard. The blow is about as high as it can be (1
5/8") -- any higher and the bass hammers won't fit under the
pinblock. The dip was quite deep (almost 1/2") and I lessened
it to make it closer to 7/16".
The aftertouch is minimal. It's there, but just barely. I
know some say aftertouch should be 0.4 mm, which to my mind is
no aftertouch.
What prevents hammers from checking on a soft blow? Seems
no matter how much I fool with backcheck angle and distance from
the tail, some of them just will not check. No, I don't think
the rep springs are too strong.
Also the touch is too light -- about 45 grams DW. Vertigris
infested the entire action, which was the main reason for
replacing shanks. Customer's budget couldn't afford new wippens
or repinning all the rep levers, jacks, and wippen flanges, so I
"zapped" them all to free them up, tefloned the knuckles,
rebushed keys, & sprayed McLube on the keypins, since the action
was extremely sluggish before. But maybe all that was too much.
I don't know how to make the touch heavier now except to repin
all the wippen parts or install new ones, or re-balance the keys
(move the key leads).

Yes, I just encountered them online a few weeks ago. It's Vanda
King. As far as I can tell, she just re-sells stuff from
Schaff.

Hi Everyone,
Has anyone here heard of or have any experience with a company
called Vanda Kinds Piano Showcase? I found some parts for an
action I'm working on and wanted to get some feedback on them.
Thanks

The back check leather has probably lost it's resiliency. Either recover
with Ecsaine or replace them altogether.
I had an old Bluthner which had the same checking problem. The
suede was a bit stiff and I replaced it with Ecsaine. I was very surprised
with the outcome, the action took on an almost luxurious feel. The checking
problem disappeared. A softer check-in removed the impact of the check
which is felt in the finger and it improved the tone - double surprise.
Be careful with a deep dip, jack can start to break on those old wippens.
Make sure the jack is not bound between the stop felt and let off button.

Hi, David:
I'm not a rebuilder, but I'll put in my $.02. The difficulty with a
longer key lies in the geometry. The hammers check because the arc of the
backcheck intersects the arc of the hammer tail. The extra length of the
key makes the radius longer than a regular key, and so the arcs don't come
together until the key has moved a greater distance thru that arc. Draw a
simple diagram with two different key lengths showing a side view and
you'll get it.
Also, beware the spring strength. If you have a short blow distance, the
spring doesn't "wind up" as much, so it will take a greater tension to lift
the hammer.
FWIW.
