Andre, I am personally delighted by the images of ice cream and cappucino
and French foods that have come our way from your contributions. No sarcasm
intended. And the hammers do indeed look delicious. Please do not be
offended.
Jason

So please allow me to confirm my understanding of this.
1. There are several (at least two) grades of Wurzen felt. These include
"regular", which has itself varied in quality over the past 14 years, and
the recent "AA" Wurzen felt,
That's right Jason kanter.
which is so beautiful that Andre's visual cortex is reminded of
delicious foodstuffs.
Is this a sarcastic remark or just 'plain funny'?
2. The manner of hammer manufacture -- how it is pressed and what shape
it is pressed into -- also come into play here. Ronsen and Renner use
different processes?
That depends on the pressed they use. As far as I know, Ronsen uses the
older hand press and Renner a new automated one. The shape depends on the
caul and on the applied pressure.
Do other manufacturers also use Wurzen felt?
Yamaha uses Wurzen regular for their CFIII-S
Samick also uses regular Wurzen. Maybe, in the mean time, other hammer
makers may have started to use it.
3. Therefore there may logically be at least 4 permutations of Wurzen
hammers, perhaps more, and we will need to be aware of exactly what we are
using and why.
Am I off base here?
The older Wurzen quality derives from when the former Weickert factory was
taken over and was called the Wurzen factory in the early 90's.
As far as I understand it, the Wurzen factory today sells two kinds of
Wurzen felt : regular quality and AA quality.
Renner is one of the main buyers and makes most of its hammers with Wurzen
felt, Abel apparently has a reason not to use it, Ronsen now also sells AA
quality but mainly (again, as far as I know) to Canada and the USA.
The other hammer makers are either piano factories like Yamaha and Samick
or hammer makers which are still not big enough players on the market to
have a real name.
So you might say that, probably, only Renner and Ronsen sell Wurzen
covered hammers.
It is up to piano technicians to make their choice.
In the future I will try to block my "visual cortex" so that nobody will
be bothered by any "delicious foodstuff"s.
OK?

One thing I’ve noticed, which seems somewhat contrary to how Andre
described the felt, is that the Wurzen he talked about supposedly had this
sort of yellowish, off white color. The Premium Blue doesn’t seem to have
that—at least the one set that I have in stock. Are there possibly
different grades of Wurzen? The felt that Ray at Ronsen is using has a
somewhat different color than the Premium Blue and the pressing is also a
different shape—more small-end-of-the-egg like (which I prefer) and less
round. I also find the Premium Blue a difficult hammer to file. While I
only have one set of Ronsen Wurzens which I’ve only experimented with, I
haven’t found the same filing problem.
David Love,
There is basically the so called 'regular; Wurzen, which has been
developed over the last 14 years.
In the beginning of this development, this felt was kind of coarse
looking, like the VFG felt Abel uses.
Then, about 5 years ago, it was bingo time because the Wurzen felt had
become more mature and was actually really good.
There were of course some minor points, like some sections being a
little hard or a little soft, but that is a matter of controlling the
pressure, needed to glue the hammers.
Today, those very same (Renner) hammers are far more consistent in their
overall pressure because of the (Renner) machine I was talking about.
Then, not long ago, there suddenly was the Wurzen AA quality. This felt
has been far more 'interlocked' and likewise is a little more dense.
It also looks different because one should compare it with the
difference between a real nice shawl and a real Kashmir shawl.
It not only looks different, it feels different and sounds different
too.
The regular quality looks like fine felt and slightly yellowish, the AA
quality looks more creamy, like nice looking whipped cream or like the cream
on a fantastic real Italian 'Capucci' .
I enclose again that nice pic of our first Bechstein prototype because
that felt makes you wanna eat it :
I hope sending this pic does not create a problem.
friendly greetings
from
