I'm not at all surprised. Some years back I ran some life tests on various action parts, including hammers. I observed that less resilient hammers (so-called "hard-pressed" German and Japanese hammers) grooved faster than more resilient hammers. The other hammers in the test were standard Baldwin grand hammers and Ronsen hammers w/Bacon felt sized to match the Baldwin hammers. Standard Baldwin hammers without lacquer lasted longer than an adjacent hammer from the same set but with lacquer and the Ronsen hammers without lacquer lasted longer than hammers from the same set with lacquer.

Flight of Broken Bass String Wim: I think it has to do with the type of hammer. I did some action work on a Steinway M today that is two years old. I had filed the hammers last August and the grooves are serious now. The Wurzen felt hammers I hung last summer are still looking very good. All these are in practice rooms with the same kind of playing by a variety of heavy hitters. dp -------------- next part -------------- A non-text attachment was scrubbed...
