What can I use for a DIY cable end? 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?

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.
