Jim Geiger, my teacher advocates CA glue without removing the pin. I tried that on a Brambach grand which had been restrung some ten years ago, but which at my first tuning, had about five pins in a row which wouldn't hold pitch. As a first step I used the thin CA glue, and it has held for a couple of years now. les Leslie Bartlett M.
