Help with coils from FT

[markus]

Just in the process of placing an order with FT & ive got stuck on the coils Im wanting to order.....to give an example :

Wire. 2.2ohm, 0.16mm*0.95m. 100 pack (NR-R-NR)
Wire. 2.2ohm, 0.16mm*0.9m. 100 pack (NR-R-NR)
Wire. 2.2ohm, 0.18mm*1.04m. 100 pack (NR-R-NR)

I guess the 0.16mm & 0.18mm is the thickness of the wire.......but what is the 0.95m - 0.9m - 1.04m ???

Also whats the difference between using the 0.16mm or the 0.18mm gauge wires ?

If it matters im looking for wires/coils to rebuild a nautilus dual coil & wondered if they could be used for others (like a kangertech protank 3)

It's the total length of each wire in mm, i.e. your first example is .16mm diameter by 95mm long

[hijack]

they have made a mistake describing the length of wire, its actually mm not m.
As you are looking to coil the wire yourself why not just buy a reel of A1 kanthal 10m for £1.90 using some .28 wire you will be able to make a micro coil as the wire is thick enough to squeeze together to form a tight coil. The wire on the FT wires is too thin to do this.


The coil on the left is the nr-r-nr wire which I use in a Penelope atty as it has to be nr-r-nr wire.
The coil on the right is .28 kanthal and makes a much better coil for threading the cotton through, and makes a nice even heating element.

I remember you saying you were going to get a hana clone, so you can use the resistance reader that's built into it to check the resistance of the coil you make.

Also to get a rough idea of how many wraps you need to have to get the resistance you want use this Coil calc. All you do is input the wire diameter, the Inner diameter of the coil your going to make and the target resistance, and it will work out how many wraps you need.

Another coil calc can be downloaded here luc. bigjohn Its a piece of software that sits on your desktop (my favourite) when downloaded it is in French but you can change to English by clicking the union jack flag.

Thanks guys, I did kinda think thats what it could be, but being a bit new I didnt want to chance it, plus I was asking myself "but why would they have 0.95 & 0.9 ? surely theres not much difference"
Now Im thinkin do the slightly longer wires have slightly bigger resistance sections ? Or is it just a longer non resistance leg ?

hijack...do I not need the nr-r-nr wire for the aspire nautilus coils ? I watched a video on youtube with someone re-coiling the nautilus & they reccomended using the nr-r-nr wire's with a 2mm silica wick ? (not sure how I managed to sit down & listen for 42mins, but some how I did)
Would be nice if I could use them, It would make it easier for me being a newbie & all that, & perhaps coz im a lazy shite.
I havent ordered the Hana clone yet as I wanted to order some coil wires & silica wick, plus Im still not sure what colour to go for ...thankfully Ive narrowed it down to just black, green, orange, blue or red .:-)
Im also tempted to get one of those IPV2's....I get right to the ordering page with CC out & then think about the video reviews ive watched, other peoples comments theyve made, think who would be the best vendor to buy from & wonder who has ones from the first batch that came over still working & then chicken out...lol

The resistance of a wire is determined by it's thickness and it's length. If two wires are the same thickness, but one is longer than the other, the longer wire will have a higher resistance.
If two wires are the same length, but one is thinner than the other, the thinner wire will have a higher resistance.

Thanks OneDay.....learn something new everyday :-)
Dunno if this is a daft question.... how does that apply to this Aspire nautilus coil where one is sat on top of the other ? I presume they use the same thickness wires but one coil is positioned slightly higher meaning its slightly longer ?.....Or is that where this NR-R-NR comes into play & what youve explained only applies to resistance wire like the A1 kanthal hijack mentioned ?

Looking at the descriptions of the two of these I reckon its the same product but from a different supplier
Both are listed as 2.2 ohm using 0.16 wire, so the length of the resistance wire must be the same in both cases.

Only difference is the total length so the non resistance legs on one set must be slightly longer.

Well, that's my guess anyway.

No you don't need nr-r-nr wire to recoil the aspire. I would try making a single coil for them first as duel coils can be a bit tricky. Take a look at this rip's recoil Try and stick with it, he might be annoying but his videos are good at showing you how. If you don't have a blow tourch then you can use the gas hob in the kitchen to do the heating bit or get one of these from FT windproof lighter.

At least your doing your research before buying a VW mod.

I cant really offer advice on which to get as I don't have either of those and it would be wrong for me to give an opinion on something I don't have or haven't seen or used.

Im sure if you start a thread asking for opinions on which to buy, people that have them will give you the pro's and con's and will tell you whether or not the FT ones are good.

Going back to the coiling.

Don't test your coils on your mech mod

Test them on something that has short protection, even an ego or evod as they wont fire a coil that has a short.

you really need a mod that will give a resistance reading as 1) you can tell if its reading what it should be, and 2) you can test it without having to assemble the whole atty and fire up the coil.

Again thanks for all the advice guys, Im glad I joined this forum......god knows what might have happened if I'd started going into this coil building blind!



hijack....Ive seen reviews from RiP Trippers before & im sure he's smoking more than VG !!...lol
I am used to doing fiddly stuff, infact I quite enjoy the challenge really...(famous last words!...lol) I will try to do a dual coil, but I think ill follow your advice & do a single coil first just to get the hang of it, Ive got a little soldering butane torch Im hoping will do the job of heating the coils, just need to find something to wrap the wire round now.
Ive taken the plunge today & ordered an IPV2 from Matt @m-Vapes, done it with a Dr Pepper attitude (Its got a 1 year guarantee...whats the worst that can happen.....lol)
Bloody good service from them BTW, ordered it at 12.30pm & they'd dispatched it by 3pm !! As you say it should help with giving me the ohm readings i need if im going to start building coils, Dont panic m8...I wouldnt have tried it on the mech mod, dont want my battery going nuclear!
What would you say was the best stuff to use for wicking? Silica wick or the cotton stuff ? I need to start ordering soon as im starting to get a stock pile of aspire coils that need re-coiling!...thanks for that link to The Vape Mesh, damn good prices, think i'll order from there.
I was going to ask about different gauge wires but i found this handy bit of info, does it look accurate to you ?

Ga...... Ohms/ft./in. @ 68F
24...... 2.04 - 0.17
26...... 3.31 - 0.28
27...... 4.15 - 0.35
28...... 5.27 - 0.44
29...... 6.55 - 0.55
30...... 8.36 - 0.70
32...... 13.1 - 1.09

Im going to hold off for a bit on the Hana mod for a bit, I think I'll see how this IPV2 goes, although I'll prob still get one when I do an order with FT, just so many nice toys on there at bargain prices!...god i could spend loadsa money on there, esp when ive seen some nice Kayfun & Russian 91% clones that would give me some experince in re-building (thats the excuse im using to justify spending the money anyway)
Ive got loadsa questions to ask, but I'll space them out, ive only been here 5mins & I dont want people to consider me a royal pain in the arse ;-)

M-vapes is a good vendor, he has some of the nicest gear at the best price in the UK. You should be sorted today then when the postie arrives.

Read Matts last post on the m-vapes thread link he has posted some info on the IPV2 that isn't in the user manual.

The aspire might be a bit easier to duel coil than the kanger, due to them having those slots that hold the coil and wick in position while you fiddle with the grommet and pin.
I spent an afternoon trying to duel coil a kanger head and ended up doing a rage quit.

I use cotton for wicks, I think it gives a cleaner taste than silica. You don't need expensive cotton from vendors Boots do good cotton balls from their baby care range, one bag will probably last years.

I think that chart might be in imperial, so 28AWG is not .28mm, you probably know that anyway. The chart looks correct the thicker 24AWG has less Ohms than the thinner 32AWG. I would stick to using metric to avoid confusion.
You don't really need to know the resistance per meter as you will find it hard to work out how much you are going to use for a coil in terms of length of wire.

.25mm will give you coils of 2.2 Ohm
.28mm will give around 1.8
.30mm brings it down to 1.6
.32mm will be around 1.4
Those are all 7 wraps on a 2.5mm former

Remember duel coils will half the resistance so for those the .25mm or lower will be needed for using duel coils in the aspire and an extra wrap or two.

I would recommend you download this software Download
This is what you will get. (Excuse the diablo wallpaper)





As you can see you just put in the wire size and the inside diameter which is the thing you use to coil on and it tells you at the bottom what the end result of the coil will be.
I use it all the time to work out what wire to use for what im trying to get.
I also use these to wrap around



£2 from wilco and has 1.4mm 2mm 2.4mm and 3mm.
