How to approach loosening up the tension in hammers so as to concentrate more at the crown, creating that particular kind of resiliency is a matter subject to no end of discussion and debate. Getting back to the original postulate that Gregor started with... namely the fellow who claimed needling into the shoulders was all <<wrong>> because it tears the felt strands apart can easily be countered by asserting that tearing (some of) the strands is exactly the point and exactly what is needed to create exactly that particular result. Needling in from the side will accomplish something else. Both, and no doubt many other methods can be used to create a very nice sound mind you. Some methods have longer lasting results then others... and all differ somewhat in the resulting sound character. A Japanese study some 20 years ago went into this fairly comprehensively... tho sound assessment was subjective in nature... still it had some validity to it. The problem with many such forwardments.... always the same, is that one basically claims that one way of doing something is <<better>> in the quantitative sense then others... if not all others without any qualification as to what quantitative criteria are being laid to ground. Indeed in the case of something as subjective as piano tone this is impossible to begin with. As to the price of the tool... Welll welll welll... how much does a high quality standard needle voicing tool cost these days in comparison eh ? Still... keep your pliers. I am comfortable with the needle tool I have. Cheers RicB
