I dont get this at all... on the one hand you reject Bernards reasoning as misinformation, and then when he turns around and uses the flip side of the same logic its perfectly ok. You cant really have it both ways me thinks. Certainly lacquer application reduces the rebounding ability of a high quality (tensioned) hammer. If you read Bernards paragraph disspationatly, he is only saying that internal friction plays an important role in how much energy is lost to the strings, and that lacquer will impede that internal friction. A direct consequence of reducing a hammers resiliency with lacquer that I see no point in trying to deny. I am sure you are not suggesting that a hammer that requires needling should recieve lacquer to improve its sound now are you ? Neither that lacquer is for hammers of <<bad felt quality>> only ? Of course not. The only point one can make here is to require Bernard to more closely specifiy what he means by <<high quality felt>> as relating to hammers. Obviously he is talking tensioned hammers, and not simply out of hand condemning softer hammers as <<bad quality>>. And just as obviously this all puts us argueing sematics again. If that is your point Dale.... to require people to not use words like <<ruin>> or <<high quality / bad quality>> regardless of what qualifiers are (or are not included) because you find the use of these words somehow offensive to the discussion... then why dont you just say so ? All I see coming clearly through is a tenacious need to defend the use of lacquer, in the face of a non existant attack on that process. > *>> May I submit that the Inner friction of felt has always been a > fairly esoteric & small consideration to the discussion of hammers > even though it is a know factor & frankly to me personally not very > useful.* Well.... our personal feelings and thoughts dont really matter much to way of things. The contribution of inner friction of felt to energy transfer in piano hammers is what it is for reasons that dont have anything to do with what we want or dont. Tho I dont pretend to know how significant a factor this is.... I certainly dont have any problem including it into the discussion. It seems tho.. that you write off its significance altogether... which would mean you have some knowledge of this internal friction process that you can share with us in defence of that claim. Which I am sure we would all benifit from. > * Rgeards--Dale* > > > > > >regards, > > > >Bernhard > Cheers RicB
