May be with a few deep stitches from the start it could gain some more active resilience. 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 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. 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...
