I did this for the 3 speed freewheel that came with my Lewis. especially fun since the freewheel was just a bag of parts. Most hobby shops carry "music wire" in various sizes, and it forms fairly easily.
Or you can save yourself a trip and unravel a piece of brake cable... a single strand will work in a pinch.
