The integrated knuckle on some piano hammer shanks, I believe, were first used by Kimball. Soooo, I have always referred to them a Kimball shanks, implying that it had an integral knuckle. In fact, I have a few N.O.S. from, I believe Tuners supply, that was only offered, by them, for a short time. I have a 194? Kimball Service Manual and it has the specs on how to regulate them, (with pictures!)<G>. I have forwarded said photos to Jeannie Grassi, in hopes that this problem system will get published in the PTJ. Unfortunately, because the manual I have is a "photo copy" type, and the photos, themselves, are regular photos of grainy quality, it's going to take someone with digital enhancement know-how to get them readable. Perhaps, Guru Jack might know the original source of these. Regards, Joe Garrett, RPT, (Oregon) Been There, Didn't Like It, So I'm Here To Stay! [G}
