Hi all, When it came time to regulate that Kimball grand in my shop, I tried out a couple of things to see what I could get away with. I had been careful choosing action parts, and I think I improved the geometry a little, without going to great lengths of re-engineering to do so, and the touch weights showed up just where I'd expect. Regulating, I started with a 9.5mm, 0.370" dip, and determined the blow distance and let off from that to arrive at a let off in the neighborhood of 3/32" bass, to 1/16" treble range. I arrived at what I thought was minimal dependable aftertouch (by feel), drop (by feel), making minor dip or let off adjustments to even everything out. Everyone who has played it has commented on how quick, responsive, and controllable it is, even at ppppppppppppppppppppppppppppppppppp, which it will just about do with these hammers. <G> Normally, I'd probably have had a little more dip, and a little more aftertouch, and have produced an action that was quite usable, but not particularly extraordinary. I know action geometry, weights and friction will have considerable bearing on what can be done with regulation, but, like I said, I was exploring. Now I have to figure out where I got lucky, why, and how to do it again next time. Looks like it's time to broaden my frontiers again. Ron N
