The CA treatment seems to = work well a couple days later when I pitch-raised and tuned the piano. =20 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. =20 This piano had a full plate with no tuning pin bushings. =20 Bottom line: CA worked great on this previously doped block.
