Hi Jim,
Pretty much all the information, secrets included, are in the 
Pianotech archives. Del started the whole thing, outlining basic 
principals of soundboard impedance, and it went from there. There's 
at least five books worth, scattered through the years since the 
inception of the list. Read and process the informational stuff 
first, and save the argumentative and counterproductive stuff for 
after you understand the basics and can put it into perspective. 
Then get into the molecules if you feel the need after hearing the 
results. There's no short path. You have to burn a lot of time, a 
pile of brain cells, and more than a little cash to make sense of 
it. It's not Voodoo, but it does cost sweat and blood. The biggest 
hurdle is getting over the idea that one can throw in a "feature" at 
random and make a predictable difference. Everything works together, 
and everything affects everything else.
