Hi Terry, Next time you find one of those wild critters, try quickly seating at the termination point of that string. If that does not change the results favorably, use your pliers to squeeze the shoulder of the hammer. If that makes a change it is a voicing problem related either to the hammer, the bridge or wire guage. IMHO You know you are on the level when your bubble is in the middle<G> Leveling strings on an upright is important only in that the hammer impacts all strings of the unison at the same time. Unless of course you have one of those raries that transpose by shifting the action. And if you should be so unfortunate to have an action where all the hammers travel slightly due to improper action to plate design, then all is not well, POS! Lots of things to look for.

I'd be interested in knowing. FWIW, on a vertical, in small print, I write the FAC numbers on the hammer moldings or on the sides of the hammers if its a nice new piano, and on grands, I record the numbers to the right of the tuning pins on the plate with a fine point marker pen. The music desk covers these small numerals when in place, and it eliminates measuring the numbers next time I come to tune. They change ever so slightly, or not at all on the same piano. Will look for you all in Chicago.......Mike Kurta ----- Original Message ----- > From: Dave Doremus > To: pianotech@ptg.org > Sent: Wednesday, May 29, 2002 12:11 AM > Subject: SAT and K&C > > > I tunes a brand new Kohler and Campbell KIG-47 today. Aside from all the damper problems I was struck by one thing. When doing the FAC on my SAT III (too many initials I know), the F reading came out -2.2 cents. I was expecting maybe +18. First time I've seen a negative reading. I did the pitch raise (25 c) with that calculated tuning and then did a pickier pass by ear and it came out fine. But I was curious if anyone else gets negative inharmonicity readings on cheap pianos and what it might mean..... >
