How To Extreme N00b Single Coil Build (First Attempt) Basic Guide

[statutoryvape]

Hello,

2 months into vaping I decided to take the leap to rebuildables; here's my first build.

==============
Hardware/Ingredients
==============
Mod: Innokin VTR V2
RBA: IGO-W

Battery: Purple EFEST 3100mAh IMR 18650 3.7V LI-MN (20A)

Wire: .28 Kanthal A1

Wicking Matterial: Authentic MUJI Japanese Organic Untreated Cotton Pads

Extra Hardware: CoilMaster and Ceramic Tweezers

==========
Making The Coil
==========
I must admit..... I feel like I have cheated a bit; I used the CoilMaster, using 1 of the 5 different size bases that give different diameters for the inside of your coil.

I used the 2.5MM version. (It is shows as "25" at the end of the base on newer version of the CoilMaster)

Even, with the CoilMaster it took me several attempts to get a decent coil. I kept crossing the wires over each other. The trick was to apply minimal pressure when spinning the wire around the pole.

I wrapped the coil 7 times around aiming for a ohm reading of 1.6-1.8. I used steam-engine.org to work out what would give me this resistance.

==========
Wiring The Coil
==========
This was a rather fiddly part....I soon learned that you need to leave one of the legs of the coil longer than the other so you can thread through the holes of the poles without having to bend and misshape the coil.

I actually used the Coil Master pole I used for making the coil to hold the coil in place while I got it in the right place and screwed it in (But i guess you could you a screwdriver or something else)

I used only one of the end posts and the center post for either legs of my coil. I unscrewed and screwed the posts multiple times and used the tweezers to pull the legs through while maintaining the coil's position using the coilmaster pole.

I eventually got the coil in place.

====================
Manipulating The Coil With Heat
====================
I screwed it onto the VTR and reading I got was 2.0 Ohms (fair enough)

I then began to pulse the power until it start to glow, I used the ceramic tweezers in order to gently squeeze the coil together. I did this until I was happy with the coil glowing from the inside out.

=====
Wicking
=====
I separated one cotton pad into two. It easily peeled apart.

I cut a third off from the cotton pad so that a half centimeter lengths could be cut off. (Making sure that the grain ran long the length)

I rolled one of the lengths up into a sausage style arrangement, dabbed my fingers in some water, and rolled one of the ends to a point so that it could be threaded through the coil.

It took a few attempts to get the right thickness for my coil.

Once threaded through coil equally, I cut the ends off so that they were hanging over the edge of the deck (IGO-W) and then began to blow on the cotton, fold and manipulate it so that it was evenly spread through one side of the deck. I used the tweezers and a screwdriver to manipulate this.

I made sure that there was no cotton underneath the coil. (for airflow)

I dripped juice using the pipette that came with my juice until there were no white cotton spots.

I placed the cap on with the air hole directly in front of the coil

=========
CONCLUSION
=========
I have to say for a first attempt, I'm impressed - Running at 6.0V, and the coil is now reading 1.7 Ohms, Flavour is good and the vapour equals that of my Nautilus Mini tank. (maybe thicker)

Its quite warm, the air hole(s) could do with being a big bigger, bit of a tight draw.

I drip onto the wick every 3-4 draws.

And that's it....my first build, not as daunting as I thought it would be. For anyone on the fence about doing this, DO IT.

I welcome any questions or suggestions - Please tell me if I'm doing something wrong.



Peace!

That was a nice detailed weite up on your first coil building experiences. Hopefully will help others who were tninking about giving it a go to pick up some kanthal and get wrapping. I am slowly forgettin what it was like to make the first coils and the excitment and for me quite frequently the let downs but still completely facinated. Please keep us posted on your future builds ☺

Well done on your first coil build mate looks ok to me and a great write up two should help other people that are starting to build there own coils on what they need to have to start out and a nice easy to follow guide on how to get that first coil build out of the way without to much fuss hopefully.

Nice write up man! Should certainly help first timers out!

I was using a 16g syringe needle, i believe is 1.65mm in diameter, and 32g kanthal. This was on the ProTank 2, my first owned tank. Was fun as a gained knowledge on which looks like an easy task.

Then onto RDA's and I'm using just a plain old 2.5mm coil winding rod, which i find is much easier then using a CoilMaster, IMO i feel you have more control. Whack the coil between ceramic tweezers, give it a quick torch, and pow, my first coil for my new RDA

Over time you pick up certain ways of doing things, wrapping all sorts of outrageous coils

P.S.. What do you think of the Muji? I've got an order coming containing that, so looking forward to trying it!

Appreciate your comments.

I'll be honest it took me an hour to get a coil I wanted, on my second coil build it took 15 minutes! But i will definitely try your method without the CoilMaster.

I heard reports of MUJI having an aftertaste but I don't sense one, but then again...I've got nothing to compare it against...certainly my juice tastes how i think it should lol. Its certainly easy (especially for a beginner) to work with, and cheap - So i rate it quite highly as an absolute noob!

Wanted to ask people a question in regards to coiling.

Currently on 5 wraps using the wire i mentioned, it's reading 1.6 Ohms.

I want to get it nearer to 1.1-1.3.

Are there any downsides to having too FEW wraps in a build. What effects does this have on heating the cotton etc.?

You'll get there man, all a learning curve

Oh so you've not tried Organic Cotton Balls yet then? I've not heard about the aftertaste, certainly seen that it wicks a lot better then a cotton ball. Will give it a go anyway, just wanted to see your thoughts with it

If you're using 28AWG, then 5 wraps on a 2.5mm diameter should measure out to be a 1ohm coil build, so I'm not quite sure how you have it to such a high resistance, with such few wraps.

Are you certain this is 28AWG? Because 30AWG with 5 wraps on a 2.5mm rod works out to be 1.6ohm bud!

Turns out it was 30AWG! Cheers bud. I've found i've got it floating around 1.4-1.6 - Awesome flavour!

And no I havn't tried cotton balls yet. I imagine it's a bit trickier to wick with those.

Nah, they unroll to a flat bit of cotton wool which is easily worked

No problem man As Jugg1es stated, cotton balls are just rolled up that's all. I find pushing my thumb through the middle tends to unroll it faster. If you have Muji though there's no need to worry about cotton
