Glad to hear what you are doing.I am sure I am one of many technicians who owe our career to you.Your book was used as our main textbook when I began piano technology at Shenanendoah Conservatory way back in 1977.One more thing.I didn't care then how to spell whippen and I still don't.Just as long as the flange is free and the springs are tight you can spell it any way you like.
