Ric Wrote I would just have loved to compare the amount of real leakage before and after on this job. I've seen and done this exact kind of job myself on a number of occasions and find that while string noise is affected significantly, leakage across to the front length per se is nearly unchanged. Demonstrated by the fact that when you measure the output of the un damped speaking length for similar pluck strengths of the front length one is pressed to find a measurable difference. Hi Ric Yes , I love A --B comparisons..they don't lie I'm not sure we are objecting to the same thing though. My opinion is that I dislike the amount of noise coming from the front duplex, Of any piano when it distracts from the sound by the sheer extraneous- ness of it, & usually I believe it is caused from the energy leaking under the capo due to low draft angles & worn capos. To me this is demonstratable in pianos I have worked with & is not a question in my mind. I rebuilt a Older 1911 B with a low draft angle. I left it unchanged. It got a new board etc. It seems to bleed or create a good deal of extraneous duplex noise. Although I don't like the noise, it is still a wonderful sounding piano by all who play it , including me. However, I would find the sound more attractive if it didn't make all that racket. Again that's my story & I'm sticking to it. The Stwy B I just delivered did break a few strings prior to the decision to rebuild it but the hammers were hard & flat , obviously lack of hammer care was a contributor. BTW this is a teaching piano. SO much of our results are subjective but when they are reaffirmed over & over again by us then we / I begin to regard them as a fact comfortable of espousing. I think we on this list do this all the time. I think we as a sensitive group of technicians are sometimes worry too much about what other people think. If we have a good rational reason for asserting a thing & can speak of it inteligentlly, then we have done out best to state a reasonable postion & we can take confidence in our own experience. It is, after all ....All we have. That and an open mind. Regards Dale Again... its my experience that leakage across to the front length per se and string noises are not all that related. Leakage as it does relate to string noises doesn't get past the termination... that energy is all used up in the functioning of the buzzing between the string and the termination. As for the new B.... I'd very much like to know whether or not their basic front length specs were changed along with the counter bearing angle. btw... I agree one hundred percent on the comment about opinions. Well said. Cheers RicB -------------- next part -------------- An HTML attachment was scrubbed...
