Gee, never heard of anything like that ever happening. Yeah, me either, that's why I asked. >I admit to being a bit puzzled by this one. > The problem is that the jack tip on a forte blow contacts the underside of > the hammer flange producing the click. Is that possible? Any chance of some photos from a foot or two back showing parts positions at rest, and with the key depressed? Gonna try for pics in the morning when I can see straight again. I hope. >The action > spread for the "L" is 111mm and the "A" is 110mm. That's in the ballpark. Yeah but are the rails? I don't suppose it's worth measureing because if they were off the spread would be too. >Neither action is anywhere > near in compliance with the magic line theory.

Sure hope I'm wrong here since > neither of the actions is even close. Congratulations, you're wrong here. <G> There are only a few action types this works on, and Steinway isn't one.

No problem. They weren't filed to the key width anyway, and if they have fronts, the originals are still there underneath, or if they don't have fronts, the overhang is random. Ron, you're gonna have to let me know when you're dropping in unexpectedly to look over my shoulder. :-) Actually no, While a sloppy job the new tops are one piece top and fronts with nothing underneath them but the un- milled keystick with sloppy trimming. >I have some budget with which to work > this out but I can't go too nuts.

Some photos of the setup might help. Ron N
