CA glue

[Leslie W Bartlett]

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.
