Hi, The factory approach to hammer shaping and voicing has varied wildly over the years. One person taught one way, another taught another way, the C&A department has used several different methods - all of these work. While what Ed suggests will definitely work, my usual preference is to shape first and then lacquer. There are both physical and philosophical reasons for this. On the physical side, the hammer is (with reasonable practice) easier to shape when "raw" (or nearly so). Philosophically, one can work at the piano, and get a sense of what the eventual sound will be before lacquering. There is no question but what adding the lacquer first can make certain aspects of the shaping process easier as it makes the hammers more like a hard-press hammer (as to shaping issues). At the same time, I do think that one (potentially) loses some control over the final product. One really crucial part of any voicing process is that one cannot get out what is not built in. One can make it louder or softer, and, within limits, affect timbre - but basically, it is a question of finding the limits of what is there to begin with and learning how to work with them. More later. Best. Horace At 09:43 PM 1/9/2001 -0500, you wrote: ><< Old Steinway hammers are a dream to > >file as the layers were thin and came off as expected.
