Hi Richard, Maybe a picture of that area would generate more objective feedback? What do both ends look like? The last 6 or so pianos that I've restrung have been "modified" to include the ½ round brass, etc. a la Nossaman, Love, Page and others. This has been VERY good to the stability of each and every one. But I figure you know more than me about that stuff. <G> But that's my two bits.

Everything went fine, but there's one area that will not stabilize--F#6 to b flat 6, all size 14 wire. I've tuned the piano several times, but I keep having to go back to the aforementioned area to clean up the unisons that have gone flat, some by a considerable amount. The pins are tight. The coils are tight. The beckets are good. I believe the bridge pins are solid (I used fresh Dryburgh superglue). Plate bolts are solid. I tuned the piano again today and it seemed that things might hold this time, but I'm looking for suggestions in case those notes go crazy again. The notes above and below are stabilizing about as I would expect with a restringing. I'll be going back in 2 weeks to check. If the problem involved only one note/string, I'd just replace the string and see if that was the cure. But there are several strings on several notes. I've restrung many pianos over the years and never had a problem like this. What's going on? Richard West -------------- next part -------------- An HTML attachment was scrubbed...
