Ah makes sense. I did wrap as tight as I could and used a 1/16th drill bit. I will try to be more consistent with the wrapping that way I can stay at 2.0ohms.
What is a hot leg and is this bad? Should I not use this head and rebuild it?

I know you probably don't have one yet (a 1/16" miniature screwdriver or similar). And it's great that you started. That's what I'd hoped, that you'd jump in and try and get one of those guys installed. And hey, the faster that we observe the problems that happen with hand-over-hand winding using the wick as a guide
and realize it the better. There's people right here on this forum still hand wrapping after years, suffering the consequences to their lungs and psyche from their equipment not working
the way it was designed to work. Why, I asked myself? Well we're communal, a group animal…and we tend to do things that way that most folks around us do. The most natural thing in the world. But it's not always the best for us, for you. I'd like to see you have that opportunity, to see what works best and get it.
So look, I think within a couple'a three days if you start winding around a drill bit, better still an instrument screwdriver with tension, you'll be seeing coils that are straight as rails. That'll stay together well enough to even try pokin' silica through 'em. Odd's are they have what you need at a dollar store or pharm near you. And that's really all it takes. If you got wire on a cardboard put it on a bobbin or anything round you can spool it on to keep as much kink or bend out of the wire. And have at it. You'll be thankin' me, I know it, once you vape the thing and see the difference. And you will because…
Electrons follow the path of least resistance, like water, current reaches out for the easiest place to go. A hot leg, is often a loose turn in the coil, usually on the end. It's separate from the rest and it becomes a narrow obstacle. When it was joined with the other turns it was like a big broad plain and current could flow easily across it. But when it's got to go through this separate little wire it bogs like a traffic jam and gets hot as hell, far hotter than the rest of the coil. The rest of the coil may be soggy and even leak, yet the hot leg burns and scorches.
Nobody, I mean nobody, can wind with the precision to avoid them consistently. I don't believe it. Can't happen. The material we're winding on very often isn't itself. Even when we make microcoils. The imperfections aren't usually evident to the naked eye. But we can overcome that second source of hot legs and shorts — with tension. When coil turns are made to adhere with tension they develop metal memory like the torsioned spring on a screen door. That contact is more easily maintained, even with handling like wicking in place after installation.
That's the coil I'd like to see you make and try. Because I have good reason to believe it will be far more satisfying and less error prone than what we usually start out with in a hand wind. I've done a few of these myself, just like you. And your's was good, very good for a first try. So I have little doubt you can do what I'm talkin' about.
Then let us know what you think, will you stiz?
Good luck.
