The last replacement cable set I got came with some very nice tiny tubing for that purpose (looked like heat-shrink tubing but thicker-walled). Wish I could remember the brand...

Before that I used insulation that I stripped off of a piece of copper wire. Copper house wiring (14ga) is a bit big but it'll work (be sure to use solid, not stranded... stranded wire insulation has grooves inside impressed from the strands). Never liked using brake or even derailleur housing as they seemed a bit thick for the purpose (many BB's have those little channels that are just a tiny bit bigger than a bare cable, and housing always seemed like a clunky fit).

Maybe extracting the teflon center tube from some derailleur housing would work... Hang on a sec, I'll try it... Yep, it's easy; cut the plastic cover away with a knife, then peel off the wires. That milky color isn't the best looking, but at least you know it's a nice friction-free tubing that's the right size! Just make sure you use derailleur housing that has the single layer of longitudinal wires; spiral-wrapped housing would probably be a whole lot tougher to dismantle.
