Shoulder or crown, you really wanted the hardness on the inside instead of the outer layers. After the initial pass, further waves of reinforcing wouldn't flow through the felt mass as easily, and thus not as far. So you judged the initial doping based on the sound (and feel) of the hammers, and how a limited set of samples (say, 1, 20, 40, 64 and 88) would respond to a given strength of lacquer. The more passes you have to make, the more the permeability of the felt becomes a factor in where the reinforcer ends up or whether it does you any good. Kind of like solid tuning where you want to land it spot on with the least amount of wire movement. Bill Ballard RPT NH Chapter, P.T.G. Bill I didn't know him but from this post I agree. The man new his stuff. This is my protocol only I use every C sharp except c-sharp 89. grin Dale Erwins Pianos Restorations 4721 Parker Rd.
