I found a pen refill that just fit into the wick hole, and wound the coil on that. Rolled the SS mesh tightly enough that it had plenty of clearance. Slipped right in. I did have to fiddle a bit with the coils, to make sure they were not too far away from wick (that gave me the hot spots), and not scraping against the wick (which would give shorts).
Also, I had read about 'cotton' for wicks, so I reached into my stash and pulled out a ball of crochet cotton. Also had a 'yarn needle', and found it was nearly a perfect fit into the wick hole of my mini-did-clone. That's what I used for winding my next coil, and it worked perfectly for me. Wound another one to put in my Phoenix clone, and used the piece of the SS that I trimmed away on the mini-did-clone, and now have a vertical SS wick in that too!
Yarn needle and crochet cotton are available in the 'yarn' section of Walmart, Hobby Lobby, AC Moore, Michaels etc. Yarn needle is also good for fixing pulls in sweaters.
Edit: Glass beads may also be available there too, called "seed beads", about the size of a sesame seed
