When you say no tension, did you find the hammers dead sounding? =20 It's not been my experience generally. =20 The importance of the staple is somewhat controversial. There are those = who argue that it adds tension to the lower part of the hammer and those = who say it doesn't make any difference. The Renner blue is, of course, = without a staple. =20 David Love ----- Original Message -----=20 From: Isaac OLEG=20 To: Pianotech=20 Sent: September 21, 2002 3:33 PM Subject: RE: hammer felt (Renner Blues) David The one I had did not really respond to voicing in the shoulders, as = being too mushy there. May be with a few deep stitches from the start it = could gain some more active resilience.=20 As it was the tension was almost none, but very nice felt indeed. Renner use this felt since a few years, and I believe actually on all = their hammers. The problem they have is that the molding they buy (I = understand that they don't do that themselves) are more stiffer than = before, and they don't like to make hammers with that sharp wooden = molding as in some Steinway, Bechstein, etc. I suspect that the Wurzen Felt, being softer, is more prone to be = damaged if forced on a sharp molding. Beside, of course they would hate = to break the moldings in the gluing process, and that is more the case = with thin moldings of course. Nowadays, All actual hammers, for Steinways, and other makes, are = generally thicker wood, and this felt that techs are often wondering how = to treat. But of course "nothing never changed " will be told you if you ask. I had to needle a C1 hammer (on a Yamaha G2) , and indeed 30 stitches = was the maximum in the medium (for first voicing), a bit too much near = the break. In the treble I begin to voice at 9:30, but finally was = obliged to go back from the low regions, as the strength was not enough. I will see that again after a bit of playing, I guess the natural = sound of this felt is enough as it is, not really crisp, mellow and = round but forcefully enough. It will be clearer in time, but not at all as the tone of the old = Yamaha hammers, so metallic, I for sure like it better (and C1 C2 hammer = assembly for Yamahas are cheap (around $430).

The Renner blue is somewhat softer than = its European counterpart. Where Andre is needing 30 stitches in the = tenor, a Renner blue will need considerably less.

I heard a = couple of sample hammers in a piano and I confess I was impressed. But = two hammers is not really a fair assesment for me however my friend has = used a couple of sets on larger steinways and he loved the sounds. But = 800 bucks is to rich for my blood. What do these hammers cost in Europe? = If it's less than half of 800 I'll try a set. Regards Dale Erwin 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 B=F6sendorfers, = 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. friendly greetings from Antares, Amsterdam, Holland "where music is, no harm can be" visit my website at : http://www.concertpianoservice.nl/ ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
