I was used in the past to cut bicycle gear cable to make my release mecanism. Ususaly I was heating the part that I was willing to cut, putting some tin-lead wire that was penetrating in the cable and then cutting it. It was preventing all the small wires to come appart, then I was just needing to grind a bit to make the edge round and it was ready to use.
Just tried doing that today, just impossible with 60W iron and Tin - lead wire. the tin-lead melt stay in beads and run away.
Do I am missing something?
Any other way or material to do that?
