It's been a while, but..... If I recall correctly heat the center of your dots, remove the bead from the flame, shove the stringer into the middle of the dots twist and break it off (OK so sometimes blowing on that puppy helps). Them melt it all in SLOWLY.
Caution: It's been donkey years since I've done this. But if your torch is on and no one else answers quickly, it's worth a try!
Still crazy after all these years...
