Can't get my head around what wire to use

[snow]

I am today having a really brain fried morning - I've been through dozens of threads, played about with online coil making software and I'm STILL befuddled. 

Having switched over to a Subtank and thoroughly enjoyed getting 2 weeks out of a 0.5 occ horizontal stock coil I have decided I would like to recoil the head at 0.5 (got the 1.2 in at the moment) at home I'll use the rba deck but out and about it'll be easier to have a couple of ready mades in my bag. So anyway perfectly happy with being able to do it however I've never gone for a subohm coil before and I have a few packs of kanthal wire here and thats where my mind has gone eh whut???? 

So my choices are:

30 AWG 0.25mm 

28/29 AWG 0.30mm 

a spool with the helpful sticker that just says 30 on it 

and 27 AWG 0.35mm (freebie from Stealth Vape) 


Which (if any) of these wires would be better for a single horizontal coil at around 0.5 ohms (dont want to go below .5 or above 1.0) ?  Probably be wrapping it around a little blue screw driver although I have lots of different rods with my coil jig so may well just go for a 3mm rod wrap.

Have you had a look at www.steam-engine.org/coil.asp . Have a play with that  ............................... if you haven`t already

I wouldn't personally use any of those gauge wires for as low as 0.5ohm too few a number of wraps to produce a good volume of vapour.
If you don't want to be buying a thicker gauge wire then 5 wraps of the 27awg on a 2.5mm bit should be good for about 0.7-0.8ohms.

I have and can't work it lol probably because as Get Off My Cloud says my wires too thin I'm happy to buy more wire though so whats the recommended gauge for what I want?

5 wraps of 24awg 0.5mm wire on a 2.5mm rod.

Hello Miss Snow,
See droog's post above...

If you take 30cm of the "30 AWG 0.25mm ", fold it in half and twist it together your result will be approx the same as 24 AWG .5mm.
No need to wait for new wire to play about...

Have fun

I'm pretty damn sure I'm using 26 gauge wire on the rebuildable bit on my kanger suntank mini .



Anything thicker and it will be difficult to get into screw slots.

I get 24 in mine no problem.

snow - I have .4mm Kanthal and 8 wraps of that will give me about .6ohm wound on a 3mm former, perfect for me. The thicker the wire, the less resistance, and the more wraps for the coil. More wraps equals more contact area for the juice, and a 3mm former gives plenty of room to get a good wick into the hole.
Hope this helps, and apologies if you have already sussed this bit

I'm using 26awg, 7 wraps on a 3mm bit comes out at 0.7.

Thank you all for the info and advice - I shall order myself some wire straight away

May already know this snow. but I've recently discovered that AWG is the USA measure and mm the UK one. There's a conversion chart here. link

No I didn't realise that beedee thank you for that link.

Just wanted to add my pennyworth,

I use a 28 gauge twisted (2 strands) on a 3mm drill bit.
5 wraps comes out at about 0.7, also the twist seems to improve the flavour. More surface area I guess, I don't really know the science of it.

I bought the wire pre twisted from www.wireandstuff.co.uk/products/Twisted-Kanthal-A1-Type-Wire---0.32mm--28-AWG--x-2-Wraps---0.5mm-x-0.1mm-Ribbon-Wire---10-Metre---Spool--183.html#SID=77

At my advanced age I don't remember anything but AWG when I started my apprenticeship umpteen years ago. Nuts bolts etc all in BSF, AF, Whitworth and so on. I never used metric.
