I saw a number of old uprights with a thin layer of felt added over the treeble hammers. That's already better than having hammer wood directly knocking on strings. Perhaps was it an improvised treatment by a former local tech? Of course generally those pianos need a complete set of new hammers. But it seems a viable temporary solution. Some customer when I explain what should be done are willing to do it, but considering the price, they prefer to do it gradually over a period of time. I always try give estimates in order of priority and it is much appreciated. My goal here is to give them a fonctionnal instrument in the mean time. I never done this myself. Have you? If so what type of felt do you use? Or do you change partial sets? I often saw the same 2 mm grey felt and even some others with buckskin leather. I never read about this in the litterature as a standard technique, but there was an article in the PTG journal about a vintage instrument with special hammers impossible to replace. A similar technique was used to preserve original hammers not only treeble. _____ J’utilise la version gratuite de SPAMfighter pour utilisateurs privés.
