My local vape shop (VapinPeace) did a spaced coil in my kanger mini. I asked him why and his reason was because the spacing heats up more of the cotton and gives a more "lung filling" vape. I wanted to get some opinions on what people prefer. The coil was an .24g kanthal .5 ohm build btw.

I like "Spaced" coils. If by spaced you mean that the Coil Loops are not touching each other.

I think they allow the Wick to Wick better. And yield more Flavor that when the Coils are Touching.


BTW - I don't build anything Lower than about .8 Ohms. And I am what Many/Most call a Low Wattage Vaper. So coil Meltdown isn't so much of a Factor to me as someone running at the Bleeding Edge of what their Battery can Handle. Or what their Meter can Measure.

3.5mm Non-Touching Coils made from 28g Nichrome 80 built to 1.10 Ohms @ 12 ~ 15W is a Standard Set-Up for me.

ETA - I use High VG DIY e-Liquids.

    IMHO it don't make much of a difference unless your using high (90) VG. As stated above wicking properly seems to make the BIG difference in my Lemo builds. When I wasn't using enough wick or it was to tight Id get leaks and/or dry hits. Now that I finally found the proper amount of wick to use my builds are all decent!
    I use a 2mm (I think) screwdriver to wrap 28 k, then push the coil down to compress evenly. I also torch the coil, use needle nose pliers to compact but not into a really tight touching wrap.
    The only time I have got shorts is when I'd accidently push the coil onto the deck while trying to make sure my juice channels were open.

    As for different size legs, as long as the distance to the center of the coil is approximately the same on both sides hot legging shouldnt really be an issue, as even a straight piece of wire "should" in theory glow from the center out

    Funny... my verticals have one leg much longer, yet I don't get a hot leg (at least, I've never noticed a problem)

    But when you fire a new one for the very first time does it always glow fron the exact center coil out evenly, or does it take a couple pulses first?

    Nowhere did i say people are getting this problem., i never stated its a common occurrence. Never tried to make it sound like an everyday occurrence. I said its a possibility in a sloppy coil, are yours sloppy? Probably not.

    If the last wrap going out to the leg is slack, more often then not that leg will glow


    I cant believe ive obviously been around so long now im the only one who remembers this being common

    Do an ECF search for hot legs dozens of posts come up

    All over the place
    I now do both (I used to only do touching-coils in RDAs), but now I typically will use spaced coils when the deck/airflow/coil gauge makes it work optimally. I just re-built my Magma with the same resistance/coil gauge, ID, # wraps that was in it previously (and both were placed at the same height/distance from the posts), but these are spaced. Flavor is better. Of course, the resistance will be the same even if the coils are compressed or not given a specific gauge length, but spaced coils will be longer and sometimes that won't be as suitable when you can opt for the same resistance and a shorter overall length of the coils. The coils I am running right now are 26 gauge dual coil and at .6Ω, I think I am pushing the limits considering much more of the coil(s) is not over the airflow.

    In my experience, assuming straight-up regular coils that are spaced or compressed, I think the nod goes to spaced for flavor. Compressed coils obviously have their place (hell, more often than not) and it really just depends on the what you are working with.

    I read a post where ECF member peraspera broke down how to make spaced coils really easily using a Coil Master. Just wrap as you normally would but send two wires of the same gauge inside to be wrapped. After wrapping, just unwind one wire and you'll be left with a perfectly spaced coil. That method makes it fun to do and easy as all get out! I think his post was in reference to Ni, but obviously Kanthal will work great in that scenario (assuming 28 gauge and under).

    I have no idea where I'm at
    Ditto, everything is a personal preference. I don't think about it one way or the other, I just wrap and if it is spaced or not, same thing really. I just try and hit my ohm goal. Different atty's like different styles, just find what works best for you and keep doing that. You don't need to use anything to wrap the coils with before hand, just wrap them directly around the coils, although I will say I started by using a piece of wire between the wick and the coil to help with wrapping, but I don't even do that any more, once you get enough practice, it just becomes instinctual.
