This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Hi David =20 Just thought I would respond to your post on voicing yamaha hamrs. = Having voiced my share at my Dads dealership I can tell you honestly = that I veiw the outcome of most efforts as not altogether inspiring .To = put another way,in our shop we never use yam. hmrs when replacing. Now = obviously ever body has there subjective bias etc. when talking hammers = but Ican not get the sound of my dreams with fact. hmrs.However as you = well know we work with what we got Right! Because of the way yam. hmrs. = are made i.e. dense felt steamed to perfection they like many wil yield = harder and yet harder felt as they are worn and filed .The densest = portion being over the tip of the moulding .As with all makes of shrink = wrapped hmrs. consistincy varys.That being said at least in the past = the pianos came in with hmr. shoulders already to weak from over = needling and theso called sacred zone untouched i.e. from striking pt. = down to molding. But because of density factors inherent in there design = that little sacred zone can be the problem and without some judicous = needling in that area and possible reenforcing of the shoulders with = hrdnrs. you probably will not be completely satisfied. Are we ever?To = emphasize my point if you obliterated all but the sacred zone with = needles the piano would probably still sound to bright Ask me how I = know. aftr filing leveling strgs ,hmrs and tuning use one needle in = that zone to locate the hard spots. Go slowly a couple strokes at a time = and listen. the brooks four corner technique is very useful as can be = couple fairly deep strokes straight down the middle . If the hmrs are at = all reasonable these few measures should help significantly.perhaps a = few more at the ends of the string marks.I find asingle needle an = enormously useful tool.Bottom line the sacred zone must be a connective = and homogeneous piece of the vocing puzzle not just a stand alone string = thumper . Hope this might be food for thought. sincerely Dale Erwin = ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
