Guys would like some views on coils, what type of coils to use for what applications, eg: tanks, drippers, coil design, ammount of wraps etc etc appologies if there is a Coils thread already.
Coils....

Hi @Cobus Walters
Maybe share a little more info on what it is you are needing help with, or what you are wanting to achieve.
cloud blowing?
flavor?
a little of both?
Building a coil is mainly user dependant- some people will put a clapton coil in a russian rta, whereas others will use the same coil only in a dripper.

Well im
Well Im into flavour where would I start
hi and welcome
i do hope that you have some knowledge with regards to ohms law and voltage etc before you continue your build ?
@Cobus Walters i would suggest taking a scroll through these threads for some pictures and reviews of coils:
General coils and wicking

view the stickies in this thread:

basically, you build which ever coil you want and put it in your device:
i have to say here, please note the boundaries of the mod (if electronic) and the battery boundaries in a mech.

I know how to get high ohms and low ohms with gauge wire but I dont even own a ohm meter I use my mods ohm reader I found suitable safe ten wraps on 2 mil drill bit with 28
Well nothing in particular I will tag along and soack it up one question how do temperature sensing work do you need a special atomizer or just the wire
Have a look at this thread for the temp control devices
Hi @Cobus Walters
Great question and I am sure many others have the same sort of question.
I have been building coils for over a year and am still learning a lot. So I don't think I could give you all the info you need to know in just one post.
But I will give you some tips from my experiences and it might help you. Bear in mind that your findings may differ. Just trying to help.
I would say you need to start with 28 gauge Kanthal wire.
Then try a 1.5mm ID
And do 7 wraps, where the wraps are touching each other (i.e. this is a compressed coil)
This should get you around 1 ohms of resistance.
Then use organic cotton wick and put it in so that its not too tight or loose.
Despite all my experiments over the past year, this simple micro-coil above still gives me a damn good vape. At around 15 Watts of Power. Not too strong or too weak. Good flavour and reasonable vapour. I am not a vapour chaser.
Once you have done that, you can then vary a few things
- Coil diameter - you can go to 2mm, 2.5mm or even 3mm. The bigger you go, the thicker the wick is and the more juice you can carry. I have always thought that for higher power applications, you need to have a bigger ID.
- Gauge of wire - you can try with thinner wire (i.e. 30 gauge) or thicker wire (i.e. 26 gauge or below). I find that the thinner wire leads to a crisper vape and the coil heats up and cools down faster. More of an instant vape. The thicker wire takes a bit longer to heat up and can also take longer to cool down. In my view, if you go bigger on the diameter of the coil and use more power, then you can use thicker wire. But you can experiment with it.
- Number of wraps - I find that if I stick to 6 to 8 wraps its best. If its less than 6, you may get not enough coil in contact with the wick and if its too many wraps it could result in the coil being too big for your device or your resistance goes too high.
- Compressed versus spaced - if you space the wraps a bit, it leads to a different kind of vape. Some say it leads to more vaporisation because the wick goes inbetween the wraps and not just inside. You need to experiment with it. My preference is compressed.
- Wicking material - there are several wicking materials. Organic cotton is the cheapest. You also get Rayon, Native wicks and Ekowool. There are a few others. Each tastes a bit different. You need to try a few and see what you like best. Some wicks work better with some flavours. For example, I like Rayon with the menthol vapes and I like cotton with the tobaccoes.
I have only touched on a few things. Hope it helps. Each device also seems to have a happy place in terms of coiling and wicking. So you need to experiment.
All the best and let us know how it goes.

That sounds like a bad idea, not to mention the headache to get them to heat up evenly.
Thing is @moonunit , the coils need to be as identical as possible, otherwise they wont heat up at the same time. If they are uneven, they wont heat up the same, so one will be hotter than the other and it probably wont work as well
I have never tried it though. I try make them idntical and get them to glow at the same time.
I hear you and I like your way of thinking!
Only way to check is to test it
Now youve wiped out about an hour of my weekend
Unless you're offering to test for us
You'll probably end up with fast ramp up on the one side and slow on the other. Which will lead to a dry hit.
I'm quite a newbie myself, and have not played with dual coils yet, I'm just speculating here, but I think my logic can't be too far off.
Ha ha
Lol, i was hoping you would do the test
I have so much in my vape queue, its quite overwhelming at the moment
But if I try i will let you know
Maybe @Yiannaki will know the answer to this.... Paging you sir...
Reporting for duty!
Hmmm. I am not so sure this would work very well to be honest.
It's definitely worth a test. I have a bit of an ocd when it comes to coiling. Not sure I could survive seeing teo different coils on a deck.
I would need to borrow some pills from @Rob Fisher to get through it
IMO: larger = more vapor, smaller = more flavour.
Wicking smaller is also a lot more hit and miss. Most folk would stick to 2-2.5mm or close to it. Kind of "middle ground" territory.
You wont notice very much difference between 2mm and 3mm, for example. But you will definitely notice the difference between 1mm and 3mm...
Im at two mil so how small can you go with japanese cotton
