This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment FYI: I CA-treated the pinblock of an old upright six months ago. Dozens of = pins were so loose that they immediately spun back on their own after = raising the pitch. I tipped the piano back and applied two bottles of = thin CA (after spending 20 minutes trying to talk the lady into dumping = the piano). It was quite apparent that the pins had been doped some = years ago - plate was all stained at the tuning pins and the feel of the = few pins that had any torque was very spongy. The CA treatment seems to = work well a couple days later when I pitch-raised and tuned the piano. I went back there last night to tune. Three pins had let go. I gave them = a tap or two and they then had a very solid feel. All the other tuning = pins had good to great torque and very good feel. This piano had a full plate with no tuning pin bushings. Bottom line: CA worked great on this previously doped block. Your = results may vary. Terry Farrell ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
