Coil suggestions using 24 AWG

[awj03130]

Hey all,

Looking for coil suggestions using 24 gauge kanthal for my dripper. Got some the other day, but I've got no idea how to tightly wrap a coil when I'm wrapping with a steel I-beam. Plus, the coils I've built so far just burn the p*ss out of the cotton...

Would like to stay below .5 ohms and above .18. I have cotton, SS mesh (400 and 325) and 2 and 3mm ekowool.


Any experience hot-wrapping with 24 AWG?

Never used that low of a gauge. I'd say use the mesh or eko since it's getting way too hot for the cotton. Maybe try wrapping looser, the coils really close together are gonna concentrate the heat. Maybe a little bigger diameter also.

Damn 24g? Above .18 and below .5? Not saying dont use it but have you tried using 28g? And if its burning up the cotton I would def use the ekowool.

7-8 wraps around a 1/8" drill bit. Otherwise, good luck wrapping that stuff directly onto any wick without badly distorting it. Check the resistance before you fire it, and I sure hope you have some good batteries and understand what you are getting into with sub-0.5 ohm vaping.

Perhaps you could re-wire some baseboard heaters with it

Cloudz - haha I know, right? The stuff is seriously the diameter and rigidity or some paperclips I've used.


As far as battery safety goes, I'm fairly familiar with the subject, have production/cycle matched and dated VTC4s or MNKE 26650s (charged to 4.125v), check every build on a box, and have enough sense to know that if it gets hot, RUN hahahaha.

Honestly, though, I sub-ohm all day and hang out in the .25-.5 ohm range. I don't mind being down there and try to take steps to mitigate my risk. Is there something else I should be paying attention to so I can increase my battery safety at these low ohm levels?

Sorry for the long post, but lastly, 28AWG is my go-to for round wire, for those wondering.

.18 - .5 with 24?? can you even make a loop with it??

I've used 26ga ribbon wire, ekowool will with stand the heat ,but it takes longer to heat

Umm, try using a wire coat hanger instead, probably a bit easier to wrap. lol. Sorry, couldn't help myself.

Although I do use dual twisted 28 with a dual coil atomizer, coming in at .3 ohms and it does perform quite well.

1/8" bit 5 wraps gives around .475-.5 and is plenty. 6 wraps gives .55-.6. Use the 3mm ekowool and twist inside it. Make sure to connect the wire, pulse the coil red, pinch it, and repeat until you have a solid orange glow before putting your aweful wool inside. If it tastes depleted, then lower the height of your coil so it is closer to the juice. If it just boils juice with not enough vapor make it a little higher. This is basically the only way I do my drippers but I use XC-116(3MM) and 6 wraps.

I kinda disagree with cotton not being able to keep up with sub .5 ohms, i use it all the time and have no issues. I think it might be the type of cotton you're using on maybe it's to tight or loose, i've built as low as 0.19 with cotton and i can tell instantly when i need to drip more before it burns. That's just my experience though, i could just be really luck or can't taste it.

It sounds like you know to be careful with this stuff, which is great. The big problem is newbies jumping into these low resistances not having a clue.

Just calculate your current draw with an equation in my sig, making sure you have some kind of a buffer between that and your batteries' ratings. I like to make sure it is at least 20%, but that is just me.

Are you really using a 26650 mod? Or did you mean to put 18650?

I don't normally think the cotton has an issue. However, with the heavier wire gauge, and the heat being distributed over a drastically smaller surface area, I believe it burns any cotton that touches it unless you've got a significantly high ohm that will produce less heat.

Like I said, I hang out in the .2ohm range all the time... But I've never fried cotton like this before!

Yeah i think i get what you're saying, my cotton burns if i do contact coils at those ohms, I find that if i keep the coil separated the cotton won't burn. Good luck though, i hope you fix your cotton issue.

Definitely gonna try this out. And also gonna do the 1/8th inch drill bit.

Worst comes to worst, I guess there's ekowool :-/ stuff has NO FLAVOR.

It is too hot to use as a micro coil. Like I said, 1/8" bit 5 wraps is what your shooting for. Cloudz said 7-8 and that will be more like the .7-.9 range which will heat slowly on that fat of wire. I just went through 30ft of this stuff so I know what I'm talking about. make sure to use really fluffy cotton, its still not the best for this situation though. If you have the means try XC-116, but at least look at the vapor production you get with 3mm ekowool. 3mm wick in a 1/8" bit is the perfect ratio. Having a fat plug of cotton all soaked in juice will reduce your wire temp to less than ideal.

haven't used the 24g but use 26g all the time and it wraps fine, but 24g is probably a lot thicker and maybe a lot harder to wrap. as you know it is best to anneal the wire first before coiling and if it still doesn't want to coil you can try electrically annealing the wire. if you do this the wire will really soften. just connect one end to the pos post of a device and the other to the neg. heat the wire for 10 seconds then let cool for 5 sec. repeat 10x's or so then immediately wrap your coil. this wire will soften a lot making it a lot easier to coil.

I use 25 mostly... I torch it, wrap it around a 2.5ish mm drill bit and fill with cotton. At 2.5mm I give it about 7 wraps for a single coil, 8-9 each for a dual coil.

 

[cantstopwontstop]

I've used 24g on a few attys mainly for single coil microcoils on a dripper with a large deck (fatty v3) I did a 14 wrap around a 7/64" drill bit (yea a 14 wrap) and it came out to just over .9 ohms. But it functions great and I'm impressed by the flavor I get from it. It is extremely hard to work with though and wont work on most RDA/RBA becuase of the thickness. Shoot for a 6-7 wrap microcoil that should give you about .5. just make sure you check before you fire.

Will be trying all suggestions on this page tonight! Big build night planned!

I agree with your disagreement. Cotton won't burn, no matter what the ohms are, as long as you have your densities down and it is supplying adequate juice. works great, hemp fiber works better, but cotton works great.

Yeah, tried the XC-116, didn't like it, wouldn't wick enough, to many dry hits, was a waste of money. Might be fine in a dripper, cause once saturated I vapes fine, but in a tank rba system, it sucked, couldn't keep up with hemp or cotton. Being stubborn I keep trying every now and then, but no. Is kewl that you can flame clean it, liked that. lol

I use hemp fiber in all my builds. Only use the cotton when testing out a new build, and if it works to my expectations, then I replace it with cotton when it needs to be re-wicked.
