Check your top coil!

[PhreakySTS9]

So when I first got my DID clone, I was wrapping much better coils than my last few tries for some reason. No matter what I did it seemed like I could not get rid of the dreaded top coil hot spot. After really taking a long look at what was wrong, I realized that my top coils weren't touching the mesh properly. So what I did was bend the top of the coil into kind of a shallow "U" shape so that the coil would be perfectly laying on the mesh. Now I have no hot spots and probably one of the best coils I've wrapped so far. I can't really get a picture on my iPhone that shows what i'm talking about, but if you look down directly from the top instead of a straight O---O line from the wick to the screw, it should look more like O^O.

I've noticed when I use the nichrome that came with the DUD I have to use this trick more than when I use kanthal, as it tends not to stay close to the wick as well as kanthal does. I hope this makes sense and may help some people. Sorry if this trick is old hat for you guys, but just simply bending the top to make the coil "hug the wick" better has made a WORLD of difference in my setups. So give it a shot if you are getting top coil hot spots and you notice the top coil isn't snug (not tight obviously, just laying on it) against the wick!

O/O is the way I do it and make sure I wrap the kanthal the clockwise so the nut doesn't loosen my coil

Just my 2¢

I've never had any problems in that regard but maybe i'll try it that way next time to see if there's any difference.

And I suppose it would more accurately be O__O for the way mine looks. Now it is O^O (kind of)

And do you mean O\O? Because O/O would be counterclockwise. Not trying to be a stickler, just trying to be sure.

Coil deformation at the top is always an issue. I've had better luck with 30ga NiCr since its stiffer. I also roll my coils around a 6d nail or 3/32 bit to get uniform loops. I also adjust the coil spacing further apart near the top while I still have it around the nail.

Here is my coil wrap on my BliSS:

you can see that the way the coil wire is mounted, it works to sorta tighten with the screws instead of against. This makes it way easier to keep the coils right next to the wick.

I've been wrapping clockwise, looking down from the top, and putting the little kink in the wire, after connecting the + terminal. I do it with my thumbnail. O^O. It's worked well. But just in the interest of experimenting, next time I wrap a coil, I'm going to wrap counterclockwise, and try the O/O.

Yeah it's been 10x better putting the little kink in it. I've been getting kind of frustrated with it lately but doing this has made it work amazingly again. I'm hoping this will keep working the way it is for a while but when it eventually does crap out I will experiment with wrapping it counter-clockwise like the pic of sprainz's BliSS. Now that i'm finally getting it down again(which is weird because I was making them great at first and then starting running into problems) I want to try to get a nicer one. Or at least one of those cool looking Chinese genesis' in the "Coming Soon to a GotVapes Near You" thread. I especially like the Cobra-lookalike one.

I have 5 of the DID clones, and now that I'm comfortable with them, I want to get a couple nicer ones too. I've been stalking the GV thread too, as well as Provapes Z Atty Pro restock.

That wrap of mine is a hand wrap.....no drill bits or non of that mess. the idear tho is to kinda use the crews to help tighten in the direction you want. as I'm tightening my positive screw I will give the wick and coils a slight twist in the same direction and it brings all the coils snug against the wick in one quick shot:

I like the drill bit method, myself. But I leave a little excess wire at the top and bottom, so that I can snug up the top and bottom wraps after I install the wick.
