Phil, you wrote : Unfortunately for us, I think that the felt properties that would make the best piano hammers are not the felt properties that most industrial customers are looking for. Wool that will make a good machine tool vibration isolation pad isn't necessarily the same wool that will make a good piano hammer. And piano hammers make up a tiny percentage of the felt market. When I was at the Steinway factory I saw stacks of felt for hammers. It looked like a lot of felt to me, but was apparently insignificant to the supplier. I was told that basically Steinway has to choose one of the suppliers standard felts because the amount of felt they buy is a miniscule percentage of that makers output, and that the maker wouldn't be bothered to make felt to their specifications for what he considers such a tiny quantity. I guess the same occur in Germany, the difference actually is that the felt provided is piano hammer felt from the start , designed and produced for that use. that diserve much respect toward the director of the felt factory. A little like if someone may say today he wants to be a piano tuner ! Best Regards. Isaac OLEG
