Greetings all, Well, I have just finished tuning this RX-6 for the fourth time in four weeks. It is stable, mostly. There was never any large fluctuations in the overall pitch, just a decreasing number of unisons that gradually became more stable. My take on this thing is that there were rendering problems, probably due to the string plate contact points under the capo and/or the upper string bearing points directly in front of the tuning pins. Each week there were less and less problems in stability, culminating today in finding about four unisons that had 2 or so cents in them. I have to hope that the piano will now be able to survive a month at a time without calling attention to itself. I lubed one of the worst offenders at both of the bearing points, and it didn't seem to make much difference. I tapped the strings down at the hitch, and gently settled them at the bridge without noticing any effect. I did use the string lifter,(a Straight-mate sort of thing), and it did send a few of the unisons crazy, but beyond all that, I think I just learned how much back and forth was required at the pin to find the neutral point in top string tension when the speaking length was at the correct pitch. The customer told me today that the piano sounds better than it ever did, and was more stable than they had ever noticed. I even got a regulation out of the deal, so it was a profitable day. I believe we, as a group, have the ability to damn near bring up all the variables possible in a situation like this. Thanks to all suggestions, regards, Ed Foote RPT
