Hi Richard, I've dealt with these a couple of times. Knabes are notorious for having bridge cap/pin problems. I know you said you used CA on the pins, but is it possible that they are still moving? jeannie -----Original Message----- From: caut-bounces at ptg.org [mailto:caut-bounces at ptg.org] On Behalf Of rwest1 at unl.edu Sent: Monday, November 08, 2010 10:57 AM To: College and University Technicians Subject: [CAUT] restringing problems Several weeks ago I was hired to restring a Knabe grand (around 5' 6" or so) that was around 100 years old. 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 No virus found in this incoming message.
