Ted: I have used Superglue to tighten tuning pins with good results. I have a customer whose ancient Steinway grand is dying note by note from the bottom of the piano. The last time I went to tune the piano I decided to try soaking the loose pinholes with thin Superglue, figuring that I had nothing to lose. I let the treated pins set up while I tuned the treble. Lo and behold, by the time I go down to the loose pins, the glue had set up and the pins which previously had zero tightness now were holding better than anything else in the piano, and I was able to tune those notes and have them hold for the first time. How long this treatment will last I don't know - time alone will tell. Patrick Poulson, RPT
