Coil diameter

[dannyhastings]

Worth nailing single coils first, before moving onto duals. I spent a few months perfecting singles until I moved to duals. Can be difficult to get them glowing evenly/wicked the same.

I just find them fiddly!! They were vastly better than the single ive built however!! Just drank juice that's all!! Don't know how I done it but they were great!!

What AWG you using? I fail greatly at wrapping thin wire. What batteries are you using as well?

I don't disagree with any of the above, but a couple of things worth mentioning:

• Make sure the coils aren't going to short when you put the top cap on, some attys are pretty bulky under the cap and it can be easy to short the coil if you go above about 2.75mm inner diameter.
• Bigger inner diameter means more juice flow in my experience. For sane builds I tend to go with 2.25mm inner diameter, wicks perfectly well. When I'm building super high power setups (think 0.06 ohm, >200 watts) I go for a 2.75mm inner diameter, that extra half a mm means you have a fair bit more juice sitting inside your coil so it's less likely to immediatly dry out with a really high power hit.

I don't really get nano coils, done a fair bit of messing about with dragon wicked nano coils last summer but never found a setup with better flavour or vapour production than a normally wicked coil with an inner diameter between 2 and 3 mm. Also, fuck stovetop coils, they look fancy but function poorly.

I don't use anything thinner than 0.32 mm / 28 awg (except for clapton outers obvs), but if you're not twisting stuff I'd get yourself some nice chunky 0.5mm kanthal, super easy to work with.

Yeah, you are right. Good additions to the thread.

Thanks pal, well I'm using 28 awg kanthan, and wrapping at 2 mm, might try 2.5 mm see how I go with that?? Also I'm using the subtank so pretty much a Kayfun deck when all said and done so pretty easy to build on!!

The thing that gets me is trapping the wires under the posts!! Damn without wrecking the coils that's the hardest but!!

Out of interest, what are you using for wick if not cotton? Surely not that glass fibre wick stuff?

Keep the coil wrapped around whatever you coiled it on while you're installing it, then pull it out when everything is screwed down tight? That's what I do on my kayfun, dunno if it's possible on the subtank.

Okay I'll give that a go in future, I just happen to have England's shakiest hands!! Oh and I'm extremely clumsy!!

Do you think the 2.5mm will work better than the 2mm??

I'm liking 3.5-3.8mm, there's more cotton in the coil ensuring it never dries out (at least for me anyway).

I'm currently experimenting with different sizes and gauges. What I am finding is that in an attempt to have a bigger coil I'm increasing the gauge, consequently it takes a couple of seconds to heat up after firing and it's a cooler vape. Still looking for the sweet spot....
