I would suspect some kind of contamination on the pin with a lubricant is the problem. A drop of thin CA glue in the becket hole would probably fix it, but this may irrevocably offend one's craftman sensibilities. It seems the issue is lack of friction, so anything to increase it should be effective. I had a string loop on a harpsichord that was slipping, and the tiniest drip of CA fixed it, and months later it is still holding fine. It beat replacing the string!

I realized that the becket was moving so took off the string, cut off the old becket and reinserted the string with a longer becket.  This one slipped as well.  Since the string spanned two notes and was high up in the piano I decided to leave it until I could decide to either replace the tuning pin or figure out exactly why this was happening.  I've avoided nickel tuning pins for various reasons (mostly looks and tuning lever feel) when possible but haven't encountered something like this.  There is clearly something about the pin which is causing this to happen but I'm not sure exactly what that is.  Thoughts?
