Tutorial - Twisted Coils
Twisted Wire.

What's it all about?

Normally I use a single length of .2 Kanthal Wire with 4 or 5 turns around my coil, this will usually give me a resistance of 1.6 - 1.8.

By twisting the wire, I not only reduce the resistance of the coil but still maintain the high coverage on the wick, BONUS!

Normally to get a really low resistance coil I would have to reduce the turns to 3 which reduces the amount of wick that is getting vaporised, not so good and this is the great thing about twisted coils.

If you are going to use twisted wires, PLEASE ensure you measure the resistance before putting it on your device, normally you will not have an issue with mechanical mods but VV/VW devices and things like egos have an amp limit on their switches which stops them firing on low resisatnce setups, usually anything lower than 1.2 - 1.5 ohms.

Once again, DO NOT use this method if you do not understand amp limits and the dangers of running very low resistance coils.

Cheers

Todd

RE: Tutorial - Twisted Coils
You can obtain the same results by simply using a lower resistance wire. .2 + .2 = .4 . Twisting wire to obtain the resistance of a thicker wire, just adds to the fiddling and does not give better results.

RE: Tutorial - Twisted Coils
*Sigh*

Just to highlight for those like Mr Happy above seemed to have missed from the video and the text.

You are getting more coverage on the coil

Also just to clarify, I didn't come up with this, it's been around for months and a lot of the more experienced atty users use this set-up and for good reason Big Grin

I just did the video as a few folk had asked me to do one.

Cheers

Todd

Oh yes it does! The thinner the coil, the bigger the surface area to volume ratio.
I've been twisted for a while and won't be going back! Quad twisted 0.1 is superb!

BTW, I don't twist for lower resistance, it's all about the surface area for me!

RE: Tutorial - Twisted Coils
So the theory is...

You are doubling the thickness of the wire to increase coverage on the wick, but as a side effect you are halfing the resistance presented to the mod?

RE: Tutorial - Twisted Coils
Must have some sense if Svoemesto sells this kind of t.w.c.

They have good engenyering attys, best silica....

This one comes with Kayfun VIII and works really good.

RE: Tutorial - Twisted Coils
Tried this on my VH today..

twisted coill with almost 7 turns (Got 1.8 resistance) the vapour and flavour was amazing

Was a lil pain to get 7 rounds on a vh though

RE: Tutorial - Twisted Coils
Good video Todd, if I had a dremmel or a drill or something I would make twisted coils but I don't so I use .25 or .30 kanthal. I think twisted would be better because there is more surface area and little groves for the juice to trap in.

Thanks for taking the time to make the video.

RE: Tutorial - Twisted Coils
Nice vid as usual Todd. Big Grin
Just out of interest what type Kanthal you using, A1, A, AF AE, D etc?


Vapalot you can just twist them by hand as well m8, the dremmel just makes it neater and quicker Smiling

I enjoy vaping nicotine in the same way I enjoy a coffee. Nicotine doesnt keep me up all night though as wired as caffeine does.
