Sorry to ask again but comes to my mind a question about felt used by Ronsen, if you don't mind. I truly appreciate that Wurzen Filz (I believe that Renner have some parts in the factory, it was in RDA, had new headquarters when privatized in 91 , web site http://www.filzfabrik-wurzen.de/eng.htm this was a well known place for felt for a long time)it looks like Cashmere wool and gives a warm tone with a lot of body. I understood that Ronsen buy felt in France at Laoureux http://www.laoureux.com/Page3.html , this felt is less resilient , thinner (that may be interesting) , I've find it can't be needled too much (fiber is not holding as much as the Wurzen IMO). Most probably Ronsen have tried any available felt and Wurzen also . Abel say he stopped using Wurzen (for "some problems")but I understand fairly well this kind of felt is not at all corresponding with the way Abel presses their hammers (hard and compact, too much warmness and pressure I guess) I suppose that Wurzen does not like to be violented when pressing, and nowadays it will never be hard as the Abel production are. I just wandered if you heard about this felt when talking with Ronsen, and if you have tried some of these (This is the felt used on Renner Blue for instance) I'll admit that probably this material in its actual presentation is may be not allowing so much voicing possibilities as a thinner fiber felt, but the tension is showing nicely and coming back after playing if over needling have been done, as the fiber looks as some very springy elastic coils, allowing always for a good rebound without the need for hardeners or such. The technicians that like it ,as me , are probably looking for the simplest way of "doing as less as possible ;>)" as a way of attaining the necessary Zen attitude that lend to nice results !!! As it need less preparation than some others and is a joy to needle I have find it as a material of choice when repairing actions. The felt does not seem to be carbonized, it is slightly yellow, and is not cracking under the needles as the whiter felts, I don't know what is the result in term of fiber longevity, but it may be possible that the carbonizing is drying the fiber, so the resiliency hold less in time (just wandering). If you have some ideas about this I for sure will appreciate it. There where a very nice felt on Bosendorfers hammers too, coming from another felt maker in Germany, V.G.F. , no more information at this moment but for sure I like to know a little more about this wonderful material... Sorry for the long post , I type fast so I think and type at the same time. Thanks in advance if you can clear me a bit. With best regards. Isaac OLEG Isaac OLEG Entretien et reparation de pianos.
