well here it is.............
I loosened the D string, and could hear it unwinding (in my mind I'm like yes!! )
I took the string off from under the string tree and pulled it out from the ball end, about 3 inches so it could further unwind it self
(So far so good)
As I restung it, (Big Twang) it broke, about 3 inches from the top end,were the silk is, and was too short to reach the tunning peghole by maybe an eigth of an inch!!
lucky/smart me I've been rotating two sets, from the denatured alcohol soaking......
So you were right, Figjam
The string that broke, seems to have broken from the twisting not the soaking
