Wanting to try duel coil Kayfun build

[Desecrate]

Hey guys, I want to try a duel coil build in my kayfun, I need to be above 1.3-4 ohmz I have 29gague flat kanthal on me. By anychace would you know how many wraps per coil it'd take to make it at those omhz? I'm a single coil guys always have been but, why not try something new! I use a "2x40" screw driver to wrap my coils. now I'm thinking that means 2mm by 40mm width to length? Any info on duel coils and ohmz and using that screw driver would be apperciated. I haven't messed with going duel, just want to see if anyone could throw me a bone on it! Thanks in advanced as usual!

Here's a image of what I'm looking at... I always take pics of everything so its moreclear what we are talking about.

Also make sure you have an ohm reader when building coils!

Also has anyone done Kayfun Dripper mode?? I want to try this.

Don't worry I got everything, Ohmz meter, Kanthal, Organic cotton all you need to get the job done.

According to my coil calculator, you're going to do a lot of wrapping. I'm getting 18/19 wrap on a 2mm screwdriver. Each coil would be about 2.6ohm, 2 coils, 1.3 ohms. Of course you will check the first one to see if you are on the right track.

Ok so when you add a coil from single to duel the Omhz drop?

I turned Kayfun into a RDA for a day.. Wasnt a big fan of this at all. I completely thought it was not for me. I am def interested in these 18/19 wrap coils can you please post pictures. i cant see how to get this to fit in my Kafun.

Yes, they work in parallel - so for example - Dual coils at 3 Ohms each would have final resistance of 1.5 Ohms, dual 2 Ohm coils would be resistance 1 Ohm, so on and so forth.

For your understanding, the paralel resistance math goes like this = R1*R2 / R1+R2

so for example if u add 2 x 1.0omh in paralel = 1 * 1 / 1+1 = 1/2 = you end up with a 0.5 paralel resistance

if 2 x 1.2 then = 1.2 * 1.2 / 1.2+1.2 = 1.44 /2.4 = 0.6

I guess thatz the tricky part of duals. Hope that helps.

Dual parallel coils with a final resistance of 1.3 - 1.4 will be a bit much to fit inside the chimney without creating a short. You're talking two coils on a 2mm rod wrapped +/- 20 times! HUGE!

Try a serial coil setup. Two coils in a series instead of two separate coils. I use a 28g round kanthal on a 2mm rod @ 4 wraps per coil = 1.5 ohm.

This was built on an Aqua but you could do the same build on a Kayfun.

Daaaaaaamn that's alot of wraps man. Ok so what I'm going to do is just leave this thread and it'll get old, but I'll try it later on if not I'll wait for a dripper but I'm going to build a nano coil to get more heat for now, when I do the duel coil build later on I'll post pics. thanks for the site and info.

LOL... see my post about serial coils. Yes, two coils @ 20 wraps each is way to big BUT... two coils in a series @ 4 wraps each will easily fit in a kayfun.

Don't give up on dual coils for your Kayfun. Dual parallel coils will be difficult but dual serial coils is easy. In the picture I posted above the "bridge" between the two coils is longer for the Aqua than it would be for the Kayfun. I had to make it that way to position the coils over the air holes but on the kayfun that "bridge" would be much shorter, keeping the coils close to the center.. closer to the air hole.

That's a dripper, I don't see the chimney hole for the juice to flow up too in the middle. You'd have to do this RIPs Way

But for now I did the calculator and it's pretty off, This was suppose to be 1.4 ohmz 14 wraps 29g 1mm I know moving it and all of that changes the ohmz and gets senesative but here's a pic I just built nano single coil.
Here's the results pic...

14 wraps 1.74ohmz calc said it'd come to 1.4 or 1.38 on a 1mm circumference

No, that's not built on a dripper. That build is on an Aqua RTA. I just don't have the chimney on ....

You could do the same (similar) build with a shorter "bridge" between the coils.

So is that just once coil over the hole, and the other one separated? Have to have a coil on the feeding hole no matter what, but from the pic I see a coil over one hole, and then a seperate one not on it. I'm guessing its just used to create more heat in the chimney chamber for more vapor?

 

[Equilibrium]

On the aqua there are two air holes... one under each coil. If you were to try this on the Kayfun you would have to make that leg between the two coils shorter and position the coils opposite (side by side between the posts) of how they are on the aqua.
