How To Build a 1Ω (0.7Ω) dual "nano" coil

[Deak]

Thanks , can't wait to get experimenting!

Deak, adding coil wraps generally increases the resistance, but adding more coils i.e making this a tri or quad (or even octo) coil setup would lower it quite heavily! Thanks to Chegs for replying though

nice and neat coil, easy to follow instruction. good job mate

Thanks VeeDubZ, first time i've done something like this but i wanted to take some photos and i thought that i might aswell use them for something half decent and worthwhile

Thanks , can't wait to get experimenting!

Just have a go dude, you can't really go wrong with this setup from what i've found. It's a pretty simple build once you've got the coiling skill down.

I thought the exact same thing when i saw Rip Trippers making this on YouTube... then he just lay it underneath and i was like "oh yea! that makes way more sense!". I'm not the biggest coiler, but this build is super super easy to do once you've got your coils nice and neat. I'd definitely recommend giving it a go dude.

Threading a nano-coil with cotton is not a trivial matter, but it can be done.



Here is a 1.2mm nano-coil, 15 wraps I think, about 1.4ohm, along with the bodkin around which it was wrapped, and the widget (a sewing needle with a loop of sewing thread permanently knotted into it) used to thread it. I thought when I made this back in September that I'd have to re-make this threading loop every few weeks, but this is still the one I made originally. I keep it tucked into my cotton wool stash, and try not to stab myself with it too regularly.

@remnant, loving this little setup... i think we should get together and make a dual nano coil package complete with a Paper Clippy type thing and the threading Widget will definitely be trying this when i get home. Thank you very much!

Just added a link to your reply in the main tutorial, thanks again!

Would love some more info on this.. I have been trying to sus making a threading needle out of twisted kanthal, but failed, the twisted needle part is easy enough its the collapsable diamond on the end I have been struggling with..

I want to be able to thread 2mm silica through a 2mm micro coil easier, so I can perfect rebuilding dual coil Protank3 heads..

But also fancy doing a diamond coil in a evod/protank head and being able to tread would make life easier..

Silica is going to be less forgiving than cotton, as far as threading is concerned. Whether you're using a collapsible diamond wire (I have a needle threader of that type) or something like I've made here, you're still going to have to squeeze through at least a short section of silica folded over, and therefore double the thickness. This is very likely to deform the microcoil.

If I was threading 2mm silica through a 2mm coil, I'd trim the end of the silica as neatly as possible, then torch the end to stiffen it, and moisten it with the tiniest possible drop of juice (to discourage fraying) then carefully push the tip through the coil, turning *with* the direction of the twist of the silica to keep it tight. Actually I've just put this to the test, and found that a moistened, neatly trimmed tip of 2mm silica will thread quite happily through a coil wrapped around a 1.5mm allen key, and maybe smaller still. I've just got a piece of 1mm silica through a 1.2mm coil as in the previous photo; the 2mm silica didn't want to go, but I'd guess 1.5mm silica (if I had some) might... these examples were done with 8-10 wraps of 0.2mm kanthal, torched in clamp tweezers after wrapping, before threading.

Having said that, I'd still probably re-wick a protank head with cotton...

Cheers for that, I will have a play.. I do single coil protank/evod heads with cotton, but I find cotton is really good with fruit flavours but tends to mute Vanilla flavours, as the dual coil head is stacked silica coils, I have tried threading cotton after positioning and everything moves..

Maybe the trick is the thread the cotton before the build, stack them with cotton insulator between, get it all together then trim the cotton..

Or just build with stacked wrapped silica, I just wanted to do the micro coils lol.. will post pics if I can get anything half decent

Brilliant, Thank you!

Great tut. Thanks for the knowledge!!

Well done
