COIL-BUILD| Nichrome (N80, 26g) | single coil for Pharaoh RTA

[Tom Penny]

UPDATE: 20180512@2300 You're better off just not using Nichrome wire and use the Kanthal 22g instead if you choose not to fancy your coils into claptons-fused/parallel. So with Kanthal22gauge7wraps@3mm-singlecoil is 41w@4.3v but so much better if you do 5wraps dual coil that'll give you a good 0.15ohms build that'll have you popping juice so sweet. Reasons not to use Nichrome is because it's a thinner wire and harder to get lower resistance especially if one decides to use it strictly for a single coil exclusively (it's really unheard of).

UPDATE: 20180511@1700 fixed several details regarding coil definition and added more info like what batteries i'm using as well as including my coil calculation images since steam-engine is unable to post a link of concurrent calculations for proof of knowledge.

AFTER READING: Pls. comment on how helpful this was to you, because vape documentation is rare! Let alone someone talking about something nobody has done before that can very well help others. So I hope you enjoyed my share. If the vaping community seems to know a lot about their gadgets I believe they should be encouraged to answer questions as often as they're entitled to do to prevent the misguided from wrong doing. Popular topic shouldn't be left to reading the almighty vape bible. It should be re-worded as much as possible! Keep up the good work folks.....people's time and patience are at risk - Information should be closer to the reader as crucial as preventing wrong doing. Continue to ask questions here and i'll get back to you ASAP.

Is it possible to use a single coil Nichrome N80 26g wire exclusively as a single coil without the need to fancy it up to be a clapton (read below to see what a clapton is)? But, when I checked what build types i'm able to safely do I get a reading of only 2wraps which doesn't sound right to me. So I need suggestion on what to build on a pharaoh RTA and if I need to make it into a clapton pls. guide me as I have other wires including Kanthal A1 rounds with me. Your suggestion will make me go out and get other materials if needed.

Still don't understand? Pls. read below on my setup specifically with the section Coil Build where I explain my problem. For reasons on Steam Engine's site for coil calculating i'm unable to post an exact link of what i've mentioned early regarding the 2wraps so I need enlightenment on what i'm able to simply achieve on my Pharaoh RTA.

1. HARDWARE
   1. Wire - Anarchist n80 26g
   2. Tank - Pharaoh RTA (silver)
   3. Mod - Voopoo Drag 157w (dual-battery or can use single battery on-the-fly)
   4. Batteries - Hohm Life 3.7v (using two, 3.7x2=7.4v, but it's amperage you should watch out for, I have no info for this ATM)
2. COIL BUILD
   1. According to Steam Engine | free vaping calculators, I inputted for 0.18ohms and my wire would then require only 2wraps for 5.4w@1.0v as a single coil build
      1. Problem is, is that isn't that absurdly too low of a wattage? Because I would love some clouds to enjoy with taste
      2. 
3. LIQUID / JUICE
   1. Clear - Fruity
      1. Skwezed - Green Apple (3mg nic)

• NOTE
  • What's a Clapton Build?
    • A build that's wrapped w/ another wire (combination coil with the main core being thicker than the wire being wrapped around it) which makes it more beefier to burn more of the cotton's surface area. Typical standard wire made for vaping is Kanthal. What I have with me is Nichrome and several others include Nickel & Stainless Steel. With the 4-wire types i've mentioned respectively two of them are meant for power wattage mode and the remaining two are meant for Temperature Control mode that your mod is capable of doing
  • What's Nichrome N80 wire at 26g?
    • A vape wire that's materialized using both 80% Ni + 20%Cr which is made for wattage mode and heats up faster than regular Kanthal wire (which is the wire I so happen to have with me at the time of posting this) and 26g is thinner than 24g so it's easier to wrap by hand and so forth
  • What's Dual-battery?
    • Mods vary with how many batteries they can use. Some mods can take up more than a single battery simultaneously. My Voopoo Drag uses 2-batteries and some ranges up to using 3-batteries even
      • What this means is that multiple batteries used simultaneously is a stronger mod capable of bumping up to higher wattages without immediately affecting the voltage. A typical single vape battery is rated at 3.7a max. Going any further is dangerous in result of a hot mod just waiting to plow an explosion
  • Wattage vs. Amperage
    • Be more concerned about amperage, but from my experience a single battery at 0.50ohms SMOK malfunction (typically they're .30 to .40ohms) on a Laisimo mod caused my battery to be really hot really quick and stopped using it immediately.

That doesn’t sound right to me either. I don’t use nichrome, but I doubt there’s THAT much of a difference in resistance. Assuming for the moment that there is, Clapton’s don’t really decrease resistance, they add surface area and dead metal weight.

One thought that is a lot simpler is a twist coil. They’re vastly easier to make, can be done without tools, and DO decrease resistance.

Why are you calculating for 1v for a dual battery regulated mod?

There isn't a way to calculate based on no. of batteries, but I prioritized ohms and inputting 0.18ohms gives me 2wraps with the N80 26g.

Oh and BTW Clapton’s don’t really decrease resistance, they add surface area and dead metal weight.

I'm interested in this. So how would I go on about doing this with the wires I have already (as below)?

- Nichrome 26g
- Kanthal 24g
- Kanthal 22g

Your mod will be able to adequately fire any simple build you make using any one of those wires. The calculation you are using is primarily for mech mods, and you aren't even inputting the correct values.

I am inputting correct info (here's an image this time):

I even went ahead and built a spaced N80 26g 6wraps single coil just to see and it rated at 0.55ohms and it's not enjoyable at all at 17w 3.0v or 25w at 3.7v

 

[Ionori]

I don't think you're going to have a good experience using such a small diameter roundwire coil on the Pharaoh single coil deck. Here's a build that should work fine for you on a dual coil deck. If you want to stick with the single coil deck, bump up the resistance.

 

[Tom Penny]

If you want to stick with the single coil deck, bump up the resistance.

I know dual coil mode would make this situation easier but how can I make my resistance go higher on a single coil on my N80 26g? Also, how do I fit two coils in the Pharaoh (like so)?

- Dual coil in the sense that for each coil it's 2-legs face the same direction and place in the same post-clamp?
- Dual coil in the sense that for each coil it's 2-legs face opposite direction and slide in one direction of each post Left A / Right B?

 

[Ionori]

The resistance is determined by the material, gauge and length of the coil, as you already have a material and gauge picked out you need to increase length by increasing diameter and/or number of wraps. The calculator has an input field for desired resistance. 8 wraps at 3.5mm inner diameter should give you a nice ~1 ohm coil.

All the Pharaoh decks except for the single coil one require half-wrap coils (legs coming out on the same side). There are 3 Pharaoh dual coil decks: postless, single post hole and dual post hole, the postless and dual hole post decks have you trapping each coil leg in a separate hole, the single post hole deck has you trapping 2 coil legs (of separate coils) in the same hole.

wait... a .18 coil with 26ga?! well theres your problem.

 

[Tom Penny]

So basically 8wraps at 3.5mm inner diameter should give you a nice ~1.0 ohm coil.

That's high ohms. So even at 30w my voltage is pretty high at 5.5v. I only will forever use what's available everywhere and that's the Hohm Life batteries rated at 3.7v. Since my mod is able to use 2-batteries i'm able to go higher than 3.7v because it's all batteries's voltage combined (3.7x2=7.4v)?

 

[Eskie]

Voltage is not a worry when using a VW mod. Amperage is. For an average 20A rated battery up to roughly 60W can be safely used. Two batteries, 120W, and so on. The resistance of the coil doesn't come into it either so long as it is within the specs for the rating of your mod. Most regulated mods are good down to 0.1 ohm.

The Pharaoh with the original clamp style deck is made for a single coil. You could mount a parallel build in it. That's made by taking a length of wire, bending it in half and carefully wrapping it around your mandrel keeping the wire parallel without crossing over the two lengths of wire. You cannot build a dual coil on that deck.

I think you need to stop calculating and assuming safety setups using settings of concern for mechs. Regulated mods do not have the same limitations. Use Steam Engine with a reasonable resistance like 0.5 ohm or higher and an inner diameter of 3-3.5 mm for that deck and you'll be fine. You can plug that into SE and get the number of wraps to use.

 

[Tom Penny]

I think you need to stop calculating and assuming safety setups using settings of concern for "mechs". Regulated mods do not have the same limitations.

I was prioritizing resistance when using coil-calculator and in the end I wanted to achieve 0.18ohms. But since regulated mods don't have the same limitations or is able to have lower resistance over a mech mod then for that I now understand. I was a little confused because I don't have a mech mod as i've stated that in my 1st-post with me having a Voopoo Drag.

I have come across several things when trying to find out what I can do with my Pharaoh, but it seems to me as if it's a tank that needs pre-built coils and I don't want to get that technical. Find a setting and slay every build with it for ease of installation. Now i'm going to be on the hunt for a no-gimmicks, featureless, color bland, easy-to-build post/postless deck - TANK (perhaps one that could give me the option to use all sorts of coils diameters just to keep it going).

Ok. I think I get it now. I’m not saying it makes sense, but I think I get it. Your math was an attempt to max out your two battery mod (for unknown reasons) and you worked backwards to get the .18ohm coil requirement.

Here’s the thing: Low ohm coils need lots of metal. I would suggest trying a 5 wrap coil of that 22 ga and see what you’re getting. It still probably won’t be .18 but it will be at least closer. Another thought is 6 or 8 pieces of that 26ga in a twist. You’ll get a ridiculously fat coil but it is a lot easier to make than an exotic like fused stapled claptons and has the advantage of being all heat wire.

The why of this whole thing continues to elude me but one thing I have noticed is that people under the impression that vaping the highest wattage possible are very difficult to dissuade. From what I have seen the concept of being able to say “yeah my vape runs at {insert ridiculous number here} Watts” is more important that actually having a functional vaping device. So go ahead. Get it out of your system.

Why is your target .18 ohms? You're using a regulated mod. You're building for a mech on a regulated mod. Very counter productive. Not to mention, shooting for .18 with a single 26ga coil? That's odd....

I think what he is trying to do is use as many watts as possible while preserving some modicum of battery life. Sort of like the vaping equivelant of “rolling coal” where the object of the exercise is not to make a functional or fast vehicle, but instead to create as much pollution as possible.

 

[mackman]

Using the wattage in his SE example his heat flux rating is cold

 

[vapdivrr]

OP, what wattage are you looking to vape at? I seen you mentioned 17 watts?

Outside of trying to get my Pharaoh RTA to work with a single coil Nichrome wire (it's not possible), i'm currently on my daily driver GEEKVAPE Peerless RDTA at a 0.12ohms Kanthal24g4w-parallel-dualcoil and at 90w it's a setting that i'mma stick with until vaping technologies progress in a direction that doesn't keep tailoring aesthetics. I'm a comfortable camper with my Peerless RDTA.

As far as wattage goes I personally enjoy 80w or more. I love that snap,crackle,pop feel with a wide drip tip. I'm actually trying to look for another tank that's postless now because I really do want to use the....Drip tip to squeeze some juice in as opposed to taking out the tank to directly have the juice be dripped into the cotton itself to then put the tank back on to vape, that's just too much work. Dripping onto a post style deck is ineffective as you're hitting the wall barrier which is the screws holding the coils away from the middle of the drip tip. A tip for postless style build deck would be to not cut your coil legs too short because you only get one try and messing up means restarting and not cutting too much.

How long does it take me to build parallel coils? A long time where I have to clear out a whole afternoon schedule just setting it up to hopefully last me about 2-3months. I'm not on my second build and 1-month in and change cotton every week or so. I highly recommend Native Wicks as they just break off so easily and evenly that there's no added work to get it to soak up juice so consistently!

Obviously at that wattage 26g is definitely to thin. As you know, if you really wanted to use that 26g, the only option would be using a couple or few together as twisted or parallel. By itself as a single gauge coil, 26g is probably good up to 30 ish watts unless you built an extremely long coil and very high volts
