hammer felt

[antares]

And then I say (speaking from a long time experience) :

Try the Renner hammers with Wurzen felt.
I don't know about the 'Renner blues' made for the US market (maybe they are
made with lower tension because of your (American) way with hammer dopes)
but at least here in Europe the Renner hammers (with Wurzen) are the very
best hammers available and you find them on Bösendorfers, Bechsteins,
Steinways and  other well known piano makers.
Yamaha uses Wurzen on their CFIIIS and these days even Samick in Seoul buys
Wurzen felt.

The Renner Wurzen hammers we use have the following characteristics :

Nice, even tone from the beginning.
Middle section needs some voicing and opening up (usually around 30
strokes).
Lower bass hammers, usually the first octave, need battery voicing (driving
up the powers from the base of the hammers).
Higher treble hammers (from c''' to c'''') need battery voicing.
The highest treble hammers, usually the last 5 or 6 hammers, need some dope
to give them a little more 'ping'.

Just yesterday, I voiced an older baby Grotrian Steinweg grand with these
Renner hammers and it took me about 1 hour and 15 minutes to needle them,
file them, clean them up and apply the dope.

Result :
A nice, warm and even sounding Grotrian Steinweg baby with a 'ping' in the
high treble.

By looking closely at the fibers of the Wurzen felt, and especially on the
sides, we clearly see that this felt is not just a dense, stone hard,
lifeless piece of felt. On the contrary, it almost seems like it was woven
like a beautiful and very expensive Kashmir shawl and after hearing the
result, we can understand why, in the earlier days, the great piano makers
in Europe used this felt.
Now that the Eastern part of Germany has been added to its former halve, the
factory has opened again, continuing to make what they had to temporarily
stop a long time ago.
