I've had a good pair of cable cutters for years, usually could cut a cable and if any wires strayed, could twist them back into line. For soldering, I used an acid flux. Don't remember what exactly, was something in Dad's box of welding stuff. Any chance the cable has some sort of anti-friction (Teflon?) coating? Assume you're soldering the end barrel? Far end should have a of chamfer or counterbore. You want to fray the cable a bit right at the end before soldering.

Don't remember what exactly, was something in Dad's box of welding stuff. Any chance the cable has some sort of anti-friction (Teflon?) coating? Cheap cables, galv wire rope, likely not coated. I'll try an acid flux. Do they list neutralizers for each type on the can/bottle? Assume you're soldering the end barrel? Far end should have a of chamfer or counterbore. You want to fray the cable a bit right at the end before soldering. Definitely NOT the end barrel. The cut end. And I don't want to fray the end because it would not fit the cable jacket or ferrule ends if it were knowingly enlarged. -- Energy and persistence alter all things. --Benjamin Franklin |

Most bike cables that are used on medium priced, or higher, and probably on some of the cheaper ones, now have plastic lined housings and even some also have with plastic coated cables. No lube required. Just for information, the housings for brake and shifting cables are different in construction and should not be exchanged. The cuts from the factory are melted, probably a cutting torch cut. -- cheers, John B. |

Or do you just throw away a perfectly good cable and buy new each time you lube your bike? That's not very eco-friendly. The cuts from the factory are melted, probably a cutting torch cut. I cut them with a cutoff wheel on a Dremel. Gently grind off any burrs. Until I figured that out, I always threw them away. Then you very carefully feed them through the jacket, making sure that you keep the jacket as straight as possible and that it doesn't hang up. If it does, you'll probably have to throw it away and start with a new one. I lube the cable before threading it. I clean the end off, after fishing it through the jacket, with white gas or naptha. There used to be an end fitting that you could clamp on with a chisel or a special clamping tool, which has a cone-shaped end into which you could flare the cable. Then you applied a drop of solder to the flared end. I haven't looked for one of those for fifty years, which was the end of my bicycle racing, so there may be a better solution now. The last time I did this, for my wife's bicycle, was maybe 25 years ago. I didn't try to put a strong fitting on the end. I just applied a drop of epoxy to keep the cable from unraveling and clamped it in the derailleur. -- Ed Huntress |

Locate for the cut, whip just past it with a strand of copper wire, then flux and silver-solder with a propane torch. Cut and use a grinder to shape the end. That's for stainless steel cable, of course. Presumably, the zinc-ed steel would be soft-solderable, but haven't seen that stuff in recent years. |
