I am in a pinch and need something to crimp onto the end of my brake cable to stop it fraying. There aren't any hardware shop's nearby and its a long way to the nearest bike shop.

Any household object that'll do the job? Any good stop-gap until I can get a proper part?

If you just want to prevent the end from fraying, you can use any sort of glue, or wrap with any sort of tape. –  Daniel R Hicks Jul 9 at 12:42

can you get hold of any heat shrink? –  PeteH Jul 9 at 13:17
    
Not immediately, it works well though? –  user12879 Jul 9 at 14:21
    
As @DanielRHicks suggested the best bodge for this is a big old blob of super glue. Worth even doing a couple of coats. –  DWGKNZ Jul 9 at 20:46
    
Along the glue lines I have had great success with a thick blob of ADOS F2. –  mattnz Jul 10 at 2:14

You can cut an aluminum soda can into a small strip and wrap that around and fold it like a tiny burrito into the end. Crimp with pliers.

I usually use an old spoke nipple. Slide it over the end and crimp with an electrical (stake-on/solderless connector) crimper.

That's what I do, and it works perfectly. But for this question, I not sure the guy have spare nipples... –  Alexander Jul 9 at 20:18
    
Actually a crimpable connector would look pretty cool. –  Jahaziel Jul 9 at 20:35
    
I agree and more likely he has one at home. Make it an answer so we can vote it up. –  mikes Jul 10 at 0:45

I have actually used these options:

Epoxy glue: let it dry a little before applying. It is too liquid just after mixed, so let it dry and use it like if it were modeling putty.

Thin cooper wire from a telephone cord. Wounded it around the end of the cable. It would look like a bass guitar string.

Solder wire applied cold, wound a couple of turns and crimp it with pliers.

Thin metal office supplies used for holding pieces of paper together (fasteners and similar) cut into small pieces and crimped with pliers.

Failed attempts were made with masking tape, electrical tape and duct tape. Soldering it was also a fail for me, the molten solder would not adhere to the steel cable, that's why I ended just crimping it.

Yeah, soldering will only work on a galvanized cable. It will not work on stainless steel. –  Daniel R Hicks Jul 10 at 3:19

Wrap it tightly with electrical/gaffa tape?

I've tried this. It's much like a finger tip bandage, impossible to keep on. –  RoboKaren Jul 10 at 14:58

The empty ink-tube of a ballpoint pen makes good cable ends. The metal ones may be squeezed into place. If you have a plastic one cut off 1 cm, put over the cable end and heat with a flame.

If you have a soldering iron and some solder, that may stop it from fraying further, but won't make it any less sharp.

You could consider a bit of alu foil, but I doubt this would stay on. Perhaps with some glue suitable for metal?

Perhaps a small cable tie done up super-tight with pliers?

Interesting, I think the cable tie might work well and would be removable when I have access to a proper cable end. –  user12879 Jul 9 at 12:34

Solder works fine, and after soldering, you cut or file a bit off the end to make it smooth and less sharp. –  Gary.Ray Jul 9 at 12:46
    
You need to clean the cable very thoroughly though. Many cables are greased at the factory and should be lubricated before being used anyway, so you need to get that off before soldering will work. –  Mσᶎ Jul 9 at 22:35

Have you tried soldering brake/shifter cable? It's stainless steel and next to impossible. You need a very powerful iron with a heat sink because otherwise the heat will wick right down the wire. Even after fluxing the cable up the wazoo, solder still won't want to stick to it. –  RoboKaren Jul 10 at 0:46

Some cables are galvanized and will solder relatively easily. Stainless steel cables are just about impossible to solder. –  Daniel R Hicks Jul 10 at 3:20
