Too much wire?

[Kevin Geroni]

So I've built my first coil. I'm using a kayfun lite clone on a innokin 134 mini. I want to stay around 1.8 ohms. I used 28ga kanthal a1 with 12 wraps around a 1/16 drill bit. It vapes, it's the right resistance. It does seem to take a bit to heat up. My question is, should I have used a different Guage wire to have less wraps. What is the max number of times I should be wrapping? I wish I would have snapped a picture before I filled the tank....

what wattage/voltage are you running?
I mainly run coils 1.4 to 1.8 and usually vape at 15 to 18 watts depending on what juice I'm vaping on.

To small mandrel, try 3/32, to many wraps, try 8-9 on a 3/32 drill bit. 8 wraps will give you around 1.4 ohms. 9 warps 1.6. The sweet spot for Kayfun's is around 1.3-1.8. But with smaller mandrels, drill bits, there isn't enough room for cotton.

What voltage and or wattage are you using.

 

[Kevin Geroni]

I'm using around 12 watts. Which is around 4.65 volts. The 134 mini is vw only. My thought was that most of my clearos are 1.8 ohm and I like the way they vape. Is that wrong? Do I absolutely need a vv device?

Not entirely true, I run nano coils in my kayfuns, yes the inside diameter is small, and takes a little more work to get them wicked, but much more heating surface area, and less dry hits.
less cotton= better wicking
more heating surface area = better vapor production
but on the flip side too much power to the coil = burnt taste
The trick is finding a happy medium between flavor, and vapor production for the juice you are vaping, there is no magic coil resistance, voltage, wattage, or wicking material, truth is you are the one vaping and only you can find your happy spot, you'll find each juice requires different combinations at different times.
To the OP'er crank up the power to that coil and and watch how it comes alive.

Your clearos use teeny tiny wire, which heats up almost instantly.

I also am running a KFL+ on a 134 using 28ga 1.5ohm @12.5w. It takes too long to heat upfor me, too. I've noticed the really thin (higher gauge) wire that came with the clone heats up really quick, but there isn't much wire to work with to get the resistance to 1.3-1.6, which is what I wanted.

I'm going to try a slightly higher gauge next time.

29 or 30 AWG will heat up a little bit faster.

 

[Kevin Geroni]

Yes the wire that came with was 32ga. It only took a few wraps but was a pain to try and make even wraps. That's y I went to 28ga. All part of the learning curve I guess. I'm just happy the first coil I ever built actually lit up.

I'm right there with ya, man. The shop gave me like 10" of 28ga, because that's all they had. If I was working off a 10" chunk of 30ga, I think it'd be just about right. I used the little phillips head screwdriver that came with the clone to make my wraps. Just about right, IMHO. Allowed me to thread a cotton wick through it rather easily.

That's a pic of my second build. I used the 3/32 as advised above. With 9 wraps. Heats up a little quicker.

Kudos to those who recognize that a smaller wire heats up quicker!

It all depends on the final results you wich to achieve, how many wraps, what gauge wire, etc. But, all things aside, a smaller wire will heat up faster than a large wire. Make the wire 10 times larger: it will have more surface area, it will take more watts of power, due to the large surface area you can vaporize more juice, on and on, but in the long run, the larger the wire, the longer it will take to heat up.

Most of my builds are done with 30 gauge. 28 gauge and larger is only useful in sub-ohm builds where they can be run with huge amounts of wattage, making plenty of heat for my cloud-chasing efforts. Massive amounts of current are usually required for sub-ohm builds. For normal vaping, 30 gauge is my preferred. 32 gauge is getting pretty small, and I use it most often for a custom build such as a parallel-wind coil or for rebuilding small heads.

Did you anneal the 32ga? Thinner wire can be pretty springy. If you anneal it before you try wrapping your coil it's much easier to work with.

I always anneal anything above 30ga. Below 30ga there's really no need if you apply tension when wrapping your coil.

 

[Kevin Geroni]

No I didnt. There was a few precut lengths that came with the clone. I was aiming for 1.8 ohms which if I remember correct was 3 wraps on a 1/16 drill bit. At the time I didn't have anything smaller to wrap around and that was already getting pretty small for my first attempt.

Hi Kev
I found good success on my kayfun/R91 with 6 wraps of 26g on a 3mm bit.
On the provari it reads 1.2 ohms and heats up instantly, and at around 3.8-4.0v
is my sweet spot with good vapor and superb flavor using a cotton wick..hope this helps! Good luck with your builds

Turn your phone the other way. (sorry couldn't resist)

As others have said stick with 30ga and you'll be better off.

My KFL build is not something most people do. I use a 3/32 bit with 6 wraps that is 1.3 ohms set at 45 degrees with cellucotton wick. And I do this with .6mm x 1mm ribbon wire.

I was getting hot spots trying the 30g and it wouldn't vape near as well for me using the heavier 26g 6 wrap micro coil, especially on the R91..

In my tank builds I run 26-27g wire on the provari that is limited to only 3.5 amps max that heats up instantly with a cotton wick in the Kayfun..good vapor and great flavor...but on my mech mods I run 24-26g parallel coils at .15-.17ohns that also heat up instantly and blow clouds that have to be seen to be believed. The heavier wire also is easier to wrap micro coils for my organic cotton wicks plus vapes more juice getting hotter than the thinner wire..its preferences here and everybody has their own.. My preference is to get the best vape possible for my buck, and for me anyway, the heavier wires do just that as I've tried them all.

good job for just starting, and listen dont get frustrated with perfect coils and all that. If it vapes good that great, it will get better with time.
