MTL coils - best resistance?

[domesticextremist]

Ooh, ooh, a MTL forum just for me

OK, so, I'm a confirmed MTL "tootle vaper".
Tried DTL and sub-ohm and wasn't bothered - whilst there is a certain pleasure in chucking clouds, it isn't outweighed by the annoyance of having to mix lower nic juice, reduced battery life, faffing with different coils and getting the airflow down low enough for a decent MTL draw. But that's just me.

Anyhoo, I've gravitated to simple round wire coils 30AWG around 1.8 Ohms usually running at around 7-7.5 Watts.
I have played around a bit with lower resistance and higher power but don't really see any benefits.
I have ventured into flat wire, which is useful because the coils are a bit more physically robust but they don't fit nicely into a lot of atties and certainly not into rebuilt stock coil heads.
I'd like to see a high resistance clapton (I'm sure it can be done) just to see if the claimed extra surface area really delivers.

So - what do others use for their MTL sweet spot?

Is somebody there? Oh hello domesticextremist sorry I must of dozed off in the corner for a few hours.

I have had my Kayfun Lite for 5 years now and in the beginning I was making simply round wire micro coils 28AWG (0.3mm) 5 or 6 wraps with a 2mm inside diameter and very happy with the vape at about 10w.

I had loads of really thin 32awg (0.21mm) left over from the days of wrapping this onto silica wick for coils and thought what if I twisted 3 strands of this together tightly, it might make a wire I could use on the Kayfun with cotton.

I made a 8 wrap over 2mm which came out to 1.2ohms and I set the wattage to 12w and the flavour that was now being produced was exceptional. This was before you could buy twisted wire or Clapton wire or anything other than single strand wire and although I have tried other builds and wire types, nothing compares to the homemade twisted 3 strands of Kanthal A1 32AWG.

I am tempted to try the Vandy Vapes superfine (mtl) Clapton SS and N80 wire..

It might be different in the material you are looking at but the vandyvape wire I bought was crap. It was ss fused clapton and was really shoddy.I find coilology and Geekvape the best wires I've used to date. I've used lots of different Geekvape and only had one real I didn't like. Crazy wire I would definitely give a wide birth as well

I’ve just ordered some coilology Clapton’s to try in my kayfun and siren. Been using ss wire a lot and I find the flavour spot on.

My current ideal coil in my main atty is 8 wraps of 26 kanthal @ 3 mm, runs out at about 1.1 ohm. Pushed to a monstrous 16 watts ( *grin*) works good for me.

General comment about twisted wire: I found a "cup hook" chucked up in my cordless hand drill was ideal to hook a loop of wire for twisting. Keep the loop taut and spin 'er up till one end breaks. Done.

SS Flat in a small gauge and slightly spaced to deliver the best flavour is a common answer, i've never really noticed any difference with claptons / aliens / tiger etc... At the end of the day the coil is heating the juice and nothing else.

If you are doing the 3X32awg(0.21) and loving it, IMO, you would not see an improvement with the VV superfine (N80).
I picked up a roll of the 30awgX2 with 38awg wrap. It vapes just like my own parallel/twisted 30awg or 32awg. (K-1)
If you want to try some,PM your address and I'll pop 40cm or so into the post for you. It's on the way.

Back when i was mtl with rta's i was adoring a 1.5ohm build. I think it was 6 wraps of 0.3mm kanthal. Was great for custards

Thanks izan very kind and thoughtful offer.

Resistance only really matters on non-variable mods, more think is physically size of the coil and wick, air flow and (this is more fine detail) the surface area of the coil. I mean x turns of y gauge with z diameter means something real, EG 7 wraps of 0.3 mm wire with 2 mm diameter, the resistance doesn't. Much easier to understand you can add or subtract a wrap/turn or go up or down on wire gauge or diameter (wraps + diameter are the same as the length of wire, and resistance if you only use one type of wire). Coil looks chunky, medium or skinny...

Not quite - there is still battery life to consider, speed of response (7W on a sub-ohm coil will take ages to get going).
Personally I tend to think resistance first then worry about what diameter/wraps gauge to use to fit it on the atty in question.

[pyr0]

I use low ohm coils with low power regulated mods.
Currently running a 0.7ohm vandy vape superfine ss316 coil in the vapeshell at 15watts and enjoying the vape

Nothing to do with battery life, except where the mods low battery voltage cut-off stops or curtails drawing power, when of the far too many lack wit YouTube reviews are all too happy to keep making vaping intimidating, over complex and repeat out dated and out of context truisms.

Couldn't disagree with you more about putting res first, ohms must havecontext (volts, number of coils etc) to mean anything that applies to vapers and or math, tall wagging the dog imo.  Ejuice and coils know sh1t about ohms law or the Joule heating equations (power you supply to your coils) that many of those YouTube vape gurus mistakenly think is ohms law and confidentially spread that fake news until everyone is poorer.  Temperature, heat, contact area, wicking and last but be no means least airflow that are actually meaningful andd important.

That sounds far more argumentative etc than I mean, but i am dyslexic and struggle to get things to make sense so please don't think i am trying to be an arse, it comes naturally.

Ohms affecting battery life = fake news (ish, a little at the extremes but not what gets bandied about)

i have used fused claptons for mtl ok it was 2x 0.2 waped with 0.1 kanthal (i went bogeyed for a week after building that lol)
i have to agree with vb on its not the resistance thats king if your not using a mech but the size of the airflow over the coil
top tip for billet box owners that want mtl but dont use the subtank rba that most come with ,find something to make the hole smaller under the coil
i used the rubber gasket out of an isub coil cut to fit and it made as i call it a kayfun like vape
in the sub box it worked rather well at 1 ohm 15 watts and had 10 ml tank that lasted a week with high nic juice lol
on a mech i tend to like it about 0.7 to 1 ohm i
on a regulated mod you can justabout use anything but i'd suggest sticking between 0.6 to 1.5 ohm coils from a shop but mtl coils norm have smaller holes in the bottom

[Roscopecotrain]

For me you can't beat the Kayfun 5 with a 1.8 old school micro coil in it at 16 watts.
Been using that setup for so long now.
