Looking for tips to start building my own (RTA) 1.8ohm coils

[Skyrex]

Hello,

I am using an nautilus mini with 1.8 Ohm BVC coils since june 2015 (i first started with evod battery and evod 2, then switched to nautilus mini in combination with kanger IPOW 2, and later bought me an extra nautilus mini and Innokin Itaste mvp 3.0). I like the more cool vape, i vape my nautilus bvc 1.8 ohm coils on +- 9 watt.

But now i want to start build my own coils on a deck, but still with a tank on it. I was thinking about a kangertech subtank mini V2. My question is: is it easy to use? and is it a good thing to go if you want 1.8 ohm coils like me? (cause sub ohm is realy nothing for me, i am a mouth to lung vaper, who likes +- 9watt; cooler vape)

If you can recommend me other RTA's? Or more helpfull tips are always welcome!

The RTA is a fine RTA as RTAs go. I have one and it works well.

Getting a 1.8-sized ohm coil (large or long) could be easier elsewhere, but you can do it.

The Subtank Mini is a great tank to learn to build on and vape with.

The Subtank Mini V2 is great to build on or use the factory coils. Simple and reliable. You can do low wattage MTL or blow some moderate clouds. They are now my main tank. You will probably find that you go to 10-12 watts and you will likely want a narrow bore drip tip instead of the one that comes with it.
I build 1.2 ohm 28 ga coils in my RBA and vape at 14 watts. A very slightly warm vape. Nice.

Okay thanks, and do you know some RTA's that are more easy for 1.8 Ohm coils then?

Thank you, the site 'steam engine' you mentioned is defently gonna help me i think!

Yes, i think i wanna go for this kanger subtank (or the mini, or the mini v2) because there are lots of movies and sites that helps with how to do it with this particuraly tank.

But i did not found any video that talks about 1.8 ohm coils for this one, so i am not sure or it will be easy to do this. thanks for your reply!!

For 1.8 ohm coil use 30 ga Kanthal 6-7 turns with a 2.4 mm diameter.
Will be a bit flimsy but work fine.
28 ga will be easier and stiffer but will take 10-11 turns.

I tried the new 1.2 ohm coils for triton mini that fits on my nautilus mini, but i already found it to hot and to intense, so i think this will be the same with this tank. So really goin to try to find a tank for 1.8 ohm coils RTA.

I think this may be a good one for that?
Other suggestions are still welcome, and some tips for new builders are welcome aswell

Oh thank you Robert, this looks like really helpful information. I translated flimsy to dutch, and it means like thinner, more fine, is that harder to work with? and if i will do it with the 28 ga, 10-11 turns, will it not be a problem to fit in it?

I do 28 ga 2.4 mm diameter coils in my Subtank Mini V2 at 1.2 ohms and love them. I wick with cotton.
I think you will want to use a narrow bore drip tip in the STM. Works much better for low wattage vaping and cools the vape down. I do NOT like a hot vape.
With a narrow bore drip tip and my 1.2 coils in the RBA deck the vape is not hot at all at 14 watts.
The 1.2 ohm stock coils also vape nice at 14 watts with the narrow bore drip tip. You can also get 1.5 ohm coils for the STM, I have not tried those. I love my STM. I have a Lemo2 as well and like the STM much more than it.
Nicer vape and MUCH easier to build on the RBA deck.

 

[Frenchfry1942]

No, 28 gauge will be fine. The inner diameter of the coil should stay at 2.4mm. You will just have to coil it a few more times. (10-11).

To have something to coil around, their are specific tools, but some people use a medium-sized nail or a thin screwdriver.

The subtank mini is a good tank and rba I think you will be real happy with it...I would try about 8 wraps of 28g. Kanthal wraped around a 2.5 mm bit...(should be around 1.5-1.8 ohms) hope this helps! I use the subtank mini as my "at work" vape.

good information, because indeed a lemo 2 was also an option, but now i know from you (you own both) that subtank mini is more easy! thank you!

 

[Frenchfry1942]

Not really easier, just slightly different.

 

[Caridwen]

Very good thread- lots of great info!
I'd say flimsy = fragile, not sturdy

 

[steam heat]

I think the blue screwdriver. The tank comes with is 2 mm....it will work to twist coils but you will have to make more wraps to get the ohms where ya want them.....

 

[Frenchfry1942]

Yes, if you use that little blue screwdriver you will have to wrap the wire around it 11 or 12 times. That will get you to about 1.8 ohms.

 

[Skyrex]

Okay, i will go for this ST Mini then i think. Yes, i need to buy some more materials i guess, like a Ohm meter, a heating source for pre-burn the metal coilmaterial, a keramic pliers, some special cotton, a tool that looks like a nail (for the right diameter). People, i am thanking all of you for your advice and tips! (more tips are still welcome, but i got to get some dinner, i'll read it later).

 

[Robert Cromwell]

Drill bits work well to wrap coils around and since you are in the land of metrics it should work well for you.
here in the USA metric drill bits are not common.

 

[Grimwald]

I have a 2.0 ohm coil on mine with 2mm diameter and 30 gauge wire. I also agree that you may want to swap out the mouthpiece. It's not my favorite rta, but it works.
