1.8 ohm microcoils using .3mm Kanthal?

[niamh297]

I was using .25mm Kanthal to make microcoils at around 2 ohms for variable wattage devices but I am finding that the coils are warping when being manoeuvred inside the protank head and have to be binned. When using the thicker .3mm wire this does not happen so much.
12 wraps of .3mm kanthal is about 1.8 ohms (I think), is there any reason why I can't just use the thicker wire for  thesehigher resistance coils? Would there be an issue with them not heating up so well? Or is there some other reason why I should not use it? The thicker wire is just much easier to work with.

niamh297 suggest you look at these brilliant guides by Super Shiney.

Even if you are making microcoils (see the link above to Super-Shiny's great guides), you may have problems fitting a coil that big into a Protank head. I'm now using .32 Kanthal which gives me a 1.4 ohm coil with about 5.5 wraps, and that is much more easily accommodated.
You don't say what you are using for wicking. If it's silica, try going up a size (i.e. from 2mm to 3mm), and also if microcoiling and wicking with cotton wool, use a larger diameter tool to wind on. The longer the piece of wire you use, the higher the resistance, meaning you could get the required ohm rating from a smaller number of coils around a larger former.
Hope that makes sense, I'm sure someone will be along shortly (no pun intended!) to correct me if I'm wrong.

Thanks for links to guides very useful indeed.
Am using cotton, handy to know that the larger the diameter the higher the resistance. Thanks.
