This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment I'm rehammering an old Bechstein (c.1900). The old hammers are hung at = between 93-95 degrees to compensate for short boring due to a greater = than average distance from the hammer flange centers to the strings. = For example, in the center of the piano, the string height would = necessitate a=20 2-1/4" bore. In fact, in the treble and tenor sections alone the bore = distance varies by 1/4". Because the hammers that I would like to use = (primary tonal selection, secondary weight selection), even with extra = long moldings, will not accommodate that bore distance and still leave a = 1" tail length, I am considering not quite duplicating the obtuse angles = present in the existing action to get the hammers at 90 degrees to the = strings, but rather uniformly short boring everything so that the obtuse = angle will be consistent from section to section and the shanks' rise = above parallel to the strings will also be uniform. Is there any = compelling reason to avoid this arrangement? What is the maximum angle = or maximum rise of the shank beyond parallel that you would consider = before problems might arise? And what sort of problems might those be? David Love ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
