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   ----- Original Message ----- From: <a href=mailto:pwilliams4@unlnotes.unl.edu>Paul T Williams</a> To: <a href=mailto:info@spurlocktools.com>info@spurlocktools.com</a> Sent: Thursday, January 03, 2008 10:08 AM Subject: key bushing cauls Hi Bill, Did you come up with your key bushing caul system before the Bushmaster?  We have a small debate on this on pianotech.
