Yes, there are other things that should be done first, but only if = you're serious about doing a complete regulation.=20 If the main complaint is "cheating jacks" as you describe them, then = by all means get them back under the knuckles. Of course, that's going = to be hard to do if the jacks are too high in the repetition = window,,,,,,,,,,,,,, and then, If the keybed isn't bedded correctly, it = could change that adjustment,,,,,,,,,,,,,,, But if the main complaint = is cheating jacks and they're too far forward, and that's all you've = been called upon to fix; then go ahead and adjust them. I personally = think that this is one of the more important adjustments in an action = regulation, but I personally never do it without making sure that the = jacks are below the windows (five minutes) applying teflon powder (three = minutes) and adjusting the spring tension (fifteen minutes), but after = you change the relationship of the jacks to the knuckles, it will change = the let-off,,,,,,,,,,,sheesh! Pretty soon, you've got a basic regulation = going there buddy! ----- Original Message -----=20 From: William R. Monroe=20 To: Pianotech=20 Sent: Friday, March 01, 2002 6:58 PM Subject: Regulating Grand Jacks List, Also on this 1973 Kimball Grand, I have the problem of jacks being out = of alignment with the hammer knuckles (I think). When played hard, the = hammers loose so much power that they do not even reach the strings. = When played softly, they seem fine and the repetition is fine as well. = Assuming that the jacks are not aligned with the knuckles once I pull = out the action and look, is there any reason not to regulate the back = edge of the jacks to the back edge of the wood core of the knuckles = without first doing any other part of the regulation sequence?
