Well done. It vapes, and didn't explode. What's not to like? FWIW, I actually prefer contact coils to spaced, but if it's working for you, keep doing what you're doing 
If it performs, it's gorgeous! Well done!Hey all,
I've been posting for just a short time, and doing a LOT of research on how all of you do your builds. I'm coming from an eVod, and just getting into my new Kanger subox. So far, I love it, and now that my kanthal and KGD came in the mail, I decided to give my RBA rebuild a try.
26 awg kanthal, and 5/32 ID coil, and the two I built have exactly 0.74 ohms. Its not pretty, but I'd like to thank you all for your advice, and past posts that helped me out.
Like I said, its not pretty, but hits like a champ at 20w!
Thanks. I've actually build quite a few more since that time...too much on youtube, lol. I have a dual coils running 0.4 with good vapor now.
Yeah, its definitely not a great looking coil, but it hits great, and made me realize that its not super hard to build coils, as long as you follow the safety rules.
Its going strong! Not pretty, but some of the newer ones are better spaced. Thanks for the vote of confidence!Good lookin build thailand. Sounds like its vaping good for you aswell.
Thanks, I tried a dual coil with no spacing and it hits pretty good too...basically 2 coils wrapped side by side. Not too bad, lolWell done. It vapes, and didn't explode. What's not to like? FWIW, I actually prefer contact coils to spaced, but if it's working for you, keep doing what you're doing
Thanks, the subtank is pretty easy to work with in my opinion.
Thanks, it works and it keeps me from analogs, so it keeps me happy. Max VG on 0.3 nic...not a bad vape! haha
---Thanks everyone, you have no idea how much I've learned and I don't think I would even have the ideas I have without you guys and gals!
Great job! Build looks good to me! I got all my info on building from this place as well! I havent tried spaced coils yet, gonna try them next build just for something a little different, thinking i might use some twisted kanthal too! Hope it looks good and wicks better!
I think you'll like twisted. I did twisted 24ga on my kayfun v4 last time I built it, ohmed out at .31 (yikes!). 24 is too big for that deck, it would've fit better in my Lemo; and it's not resistive enough for dualies unless you're going waaaaaaaaaaaaaaaaay subohm. I think twisted 28s would be better, and maybe twisted 30s for duals. A triple twist 32 sounds interesting as well. Tried Claptons yet? I like them better than any twist I've vaped yet. It's a major PITA to wind the wire, but good vapor and a lot of flavor.
Havent tried Claptons yet, i want to figure out twisted coils first then try Claptons. The sure do look sick though!
My first try at claptons. 28 wrapped with 32. 6 wraps at 1/4" each. Ohms out at .23 and takes 100W to fire em, but WOW!!! I can clear an entire eye dropper full of juice and smog out my living room in one puff. Lol! And the flavor is awesome!
Lifted from the thread post 426 ReadyXWick - Round 2 | Page 22 | E-Cigarette Forum, some thoughts on winding basics.
If they're spreading at all rudy, you're still shy of the tight fit we're lookin' for. What I refer to as closest proximity. Stands to reason that the more firm the pressure on the iron, the better the press. Same principle. As close as nature allows is exactly that.
Then…when you pulse you get very quick oxidation. Very even insulation. That's the goal. That's what turns a shorting contact coil into a proper complete circuit much less likely to produce hot turns or leads…in operation. TRUE…good symmetry will give you a working result. But that stability changes the minute we apply a working power level (resistance goes up in operation). More than the 3.5-3.7V that we use to pulse the coil.
The higher the power we intend to use the better the insulation must be. Strain in the wire keeps the wind tight. Gives every pulse we apply the best chance of layin' down alumina in a consistent way. There's where the payoff is. And what is that benefit? We've reduced the amount of wasted energy that would otherwise bypass the circuit.
All winds work. But that's not what we're talkin' about here. It's how good an insulation we put down for the power we want to apply.
I pitch tension winding because it's been used forever. From the first time we wound wire into hoops for chain. For us this ancient tech has an electrical benefit. And it's extremely easy to do. But a blunt needle may not be firm enough to let you strain the wire if it's a thicker gauge.
Don't forget it's about leverage and using the edge of the spool as a rest for the bit. This is key. It's what let's you multiply the force by letting you pull against the wire using the light strength of both forearms. Rather than just wrists or fingers. These we want more relaxed to sense the pressure we're applying to the spool, the bit and the wire. Shake out your hands if you get tight.
In your case for 3mm, a used 3/32" drill bit will do ya just fine. Start with a few loose wraps until you see them tighten. Then practice adding just a little more pull. The result you will eventually see in your vape with a significant cool down of the vapor. In fact, more of it as due to the even distribution of heat across the coil (rather than lost to air). As I note often, the tell for too much strain is when the heat goes up for the same wind.
If you've used just enough and just a tad more than needed to get 'em to stick together as in my above you're going to be golden.
You can also use strain to make open winds that are rigid and stable on a screw using the same pin vise. While it won't produce the concentrated power of a tensioned micro if well oxidized will resist warping much better.
Good luck rudy.
Predictable, repeatable power delivery and resistance. Takes 10$ and 30 seconds. G'luck all.

heres my first built, and yes that's a subtank mini. 26g obviously twisted together reading .5ohms
GOOOOD. But it takes a while to heat up. I only have an istick 30w.Looking good, coilburner.
Its only a micro coil, I mean that is on the rba deck of a subtank mini.
You could use a highter guage less ramp-up time. I enjoy twisted 26 though its my take about vape.
I tried my friends kanger subtank rba build. He used 6 coils with 28 gauge kanthal wire, it was quite bad as i got alotta juice in my mouth, anybody can help?
