I know I am sticking me neck out for a flaming, but I have been extremely successful in handling tight Asian centers using WD-40. Yes, I know, but it _works_! I have a piano, Korean yet, still under warrenty where the damper flanges and top flanges froze up and I was facing repinning the entire damper action. I called the dealer who sent a technician who used WD-40. I said, "That won't work!" He said, "Ja, it vill." Two years later they are still free, so were the tuning pins, so in it went for a repinning job, by the dealer. Oh, well we all must have trials in our jobs. The next time you have a Yamaha, Kawai, or Korean piano with frozen pins try on or two and see. I do not know why the freeze up or why WD-40 works. They do and it does, so there. I haope all of you are well. Newton
