I was near a Performance bike shop today, stopped in, bought the Park cable cutter ($38), ferrules ($0.25 each) and end caps ($0.10 each). I was tempted to get the Felco online instead, for $60--only a $12 difference, but the Park was immediately available and, as it turned out, the tool includes the correct spacing crimping dimples for both end caps and ferrules, so that was convenient.
I will hopefully remember:
- Use good cable cutters
- Degrease the cables before attempting to super glue the ends
- Crimp the end caps good and hard, so they won't fall off
- If it comes time to pull out a cable and re-use, just give a good, hard yank on the end cap with some pliers.
Thanks to everyone who posted. It was a great help!
