I have tried several different configurations, currently I am using a 28ga kanthal wrapped around a 5/32 drill bit. I think I did 10 wraps and it checks in at 1.8 ohms. Here's a picture of what it looks like, this one could be tighter on the side that's facing the center post, but it works: imgur: the simple image sharer
Check out https://www.youtube.com/watch?v=K1f7vPpEeN8 for a good tutrial on nano coils and how to set up an RSST for auto dripping. I think he may have some micro coil ss mesh tutorials too!
because to me that coil doesn't look like it matches the opening size for the wick which would imply your wick doesn't "fill up" the wick hole? It looks much smaller, from what I have read the hole is around 3.2mm in diameter so you would want to use a drill bit that is as close to 3mm as possible?
