Have a drill, just need the diamond disks, didn't think it was possible to do a controlled enough cut with a drill, you have no problems with that?
Though having various power tools makes it easier and less time-intensive, you don't need fancy specialized equipment to make these things. Even though I have bench grinders, presses, metal/wood/stone saws, and & other stuff lying around, I just use a Dremel & a diamond disk (and water) to make my wicks, and I've made quite a few. Some folks don't even use a Dremel, just a regular drill or oscillating cutter. The biggest requirement is a little time & patience..... and it's actually fun (after you get past the "I broke ANOTHER F*ing one!" phase).
Remember - the Wheel was invented with a stone-hammer & a bone wrench, and the Ancient Egyptians built the Pyramids with nothing more than stone & soft copper tools..... just jump in & play around a bit, you will be well rewarded.
Have fun...
