I learned it back in the mid 1980's from Del Fandrich, who had learned it from another tech in the Portland area some years previously. Later I heard form a British technician who had used a similar method many years earlier at Steinway London. So it seems there is nothing new under the sun. My wife and I are just the ones who actively taught the method, starting in 1988, and soon after made the cauls commercially available.   Bill   </blockquote> Aha! The Bushmaster was being marketed on the East Coast in 1986-87 by Peter Grey - who claims to have invented it (he patented it).  It didn't get wider exposure until several years later, when Pianotek took over distribution. So that seals it - Bushmaster was first. Israel Stein  </body> </html>
