Twisting resistance wire?

[Commie]

I had an idea, but can't quite test it right now as I'm at work. Has anyone tried twisting together two resistance wires (which should half the resistance) and then making a twice longer coil? Would this be about the same result with much less effort as a dual coil? As in, more heated surface?

Thinking of trying it on my phoenix clone

would it not be easier & cheaper to use thicker wire if you want a longer coil?

twisting together 2 resistance wire simply puts them in series and is no different than cutting a resistance wire of the same length, unless you're planning to do a dual coil its redundant to do that. Also just to add if you're looking to coil low resistances I would suggest you try the 30awg kanthal A instead of the 32awg that most pple use, which is 0.25mm in diameter. I got mine a week back and I'm really satisfied with it, it's stable, the resistances rarely change due to gunk on it and i'm able to put 4 coils on my wick to get 1.2ohms, using about 3.8cm of resistance wire. Hope this helps.

It would, but I only have one wire, and lots of it Easier and faster to experiment with what I have rather than buying another spool just to try

Sorry to say this, but this is wrong. I think you might have misunderstood what I was trying to do.

I tested tonight:

chunk of nichrome (about 2 inches) -- 6 ohm
two chunks of nichrome (also 2 inches), braided together -- 3 ohm

Before I'd make a coil with 4 loops (couldn't fit more into a Vivi Nova) -- 3.5 ohm. Now, the same coil with the same number of loops is 1.9 ohm. Yay!

If you have plenty & it works for you then thats the way to go

Thats the way I build most of my coils. I use either dual or triple braided kanthal to get down to around 0.7 ohms. If you are trying to push the ohms down, it works well. It also seems to make coils that last a good deal longer. I've had quite a few make it over the 2 months mark with the triple braid, and thats pushing them at 5v heavy.

It seems to work very well, if you braid them consistently. I had a few coils burn out, and after inspecting them, I realized that there were spaces of about 1/4" where the two wires were parallel rather than twisted together.

If you twist two wires in parallel, you get a beautiful legend of a big surface etc. And when you try this, it can make a difference. But it's for short time: after a while the spiral gets dirty and effect disappears Anyway everyone can try

can't take all that vapor. lol

Caution!

While this works pretty well in a phoenix, it does bad things to Vivi Nova. Such as burn the little rubber insulator stoppers, giving them this wonderful taste of deep fried tires. It also ruins the juice in the Nova. If you pour the juice from the Nova back in the bottle, it ruins the whole bottle.

As a matter of fact, is any moderator sees it, could you please add this caution to my original post, since I can't edit it any more.

What atomizer is that?

Since I believe most people already double back and twist the legs on nova coils to prevent burning the rubber, wouldn't it make sense that one could double twist the coil and then triple twist the legs?

Looks to me like a Orion (hybrid).

I used .16 nichrome twisted on my odysseus and penelope a lot and sometimes .20.

Using .35mm for a while and .......m im not looking back ! Beware these wire is thick as hell lol and i can see it being a problem to wrap/coil some attys.

This set up will always give you LR 1.3 to 1.5..ohms i use 34awg .20 nichrome or kanthal twisted together 5 coil wrap over a small piece of cig paper.. awesome vape at around 4.5 with no hot spots or over heating cap on the did atty....enjoy your vapor!!

Tried this myself with 32guage/0.2mm since I wanted more coil area at around 2 Ohms (for use on my passthrough modded Ego - won't run anything less than 2 Ohms) - I haven't yet had much luck winding coils directly onto SS mesh without shorts anyway, but my concern would be that the 'high spots' of the wire would make this even harder, offering a focal point for forces to break through the oxidised layer of the mesh causing shorts, but I see several of you in this thread have used the twist without this issue anyway. Myself I had a tube of fibreglass over the mesh wick so no bother in that regard LOL!

Also, if you're after a very particular resistance note that folding a lenght of given resistance wire into 2 the twisting it, doesn't tend to give you a piece of 1/2 the res. of the whole length - it tends to be somewhat less, and the tighter it's twisted, the less it will be due to the extra contact points along the length of the spirals - a 4 Ohm piece (taking into acct. the length needed for the terminals as well of course) well twisted gave me 1.8 Ohms and my Ego wouldn't run it so I had to make another. After dropping that one on the workshop *floor I was at coil 3 before I had a working atty LOL.

*(my workshop floor is a partial black hole treasure trove of various dropped bits, and as a maker of silver jewellery also, a lot of it a bit precious - it takes so much in but rarely if ever gives any up - one day I expect to find a way to mine it though... )

You may have misunderstood him - I think he meant two of the same length side by side and twisting them together in parallel; effectively cutting the resistance in half.
