Built My First Setup Yesterday

[Trypno]

So I did my first coil build ever yesterday. It was on my asMODus 26650 rda. So far I'm liking it, but the ramp up time leaves something to be desired.


It's a quad micro coil setup. The coils are running in parallel, not series. Each coil is made up of 28ga kanthal @15 wraps a piece with a 2mm inner diameter. This brings each coil to 2.0ohms, which when put together brings the total build down to 0.5 ohms.
I'm vaping max vg unflavored liquid @3mg from Mt. Baker Vapor. I like this build, it's not too hot, and not too cool for me. The only problem I'm having is ramp up time. It seems to take forever to heat this build up. Anyone have any tips? I screwed the posts down more, that seems to have helped a little.

.5 ohms is way to high for 28g quads, maybe 31-32g. Also that's a TON of wire to heat/cool!
Try maybe .25-.3ohms.
Personally i prefer to use 30,32 gauge for quads. My coils are always 1.98mm ID. Leaning more towards 32g lately, and also thinking of getting 34g to do 6, 8, or 12 coil builds lol(yeah right that would take me a week to build, and 2 weeks to wick it). I've said it before and I'll say it again thinner gauge wire,multiple parallel coils.
way better than thick gauge wires with less wraps and/or coils.
but all that is just my opinion
multiple parallel coiled outperforming vapor and flavor, but that's just true because I read it on the internet so it has to be

I will definitely keep that info in mind. As it is, all I've got to work with is 28ga.
So I did my third setup yesterday, dual coils, twisted kanthal, 9 wraps around a 1mm post. Each coil reads about 1.0 ohms, so the build itself reads about .5ohms.

Does that heat up any faster? You're pretty much using the same amount of wire, do the twisted duals work better than the quad coils?

 

[DaveSignal]

When you add more wire or thicker wire, the resistance needs to drop because you need more power to heat up all of that wire quickly. I would do the above twisted build with half as many wraps.

 

[Trypno]

This build actually heats up much quicker than the quad build I had, and isn't as hot as a .5ohm untwisted build.
According to Rip Trippers twisted 28ga build video, which is where I learned this build, twisting the wire increases the gauge of the wire, causing a decrease in the resistance. But that's just from him, personally that's exactly what I think it did.
The diameter is also decreased down to 1mm with this build as well, rather than the 2mm I had in the quad build.

well yes, a lower gauge wire has a lower resistance, but needs to be at a lower resistance... you can't just add wraps to make it the same resistance as your thinner wire and then expect it to work the same.

for example, if I am building a dual coil build at .3 ohm and then want to add 2 more coils, if I put twice as many wraps on all of the coils, I can still end up at .3 ohm, but this isn't going to vape anywhere near as well as my dual coil .3 ohm.... it needs more power than that, because there are now 2 more coils. So I would add the two extra coils with the same amount of wraps as if I were doing duals, only now I would be at .15 ohm... but this is the kind of resistance that is needed on a mech to power all four of those coils and get them to heat up in the same time.

Instead of building to a target resistance, it is better to build for a targeted vape experience, as different gauges and number of coils will require different resistances. I would bet that you get a much better vape if you make those 9-wrap twisted coils 5-wraps.

Just build a 0.5ohm single coil is my tip. I have a twisted 28ga build right now its only 4 wraps and ramps quick. Most ppl don't believe its just a single coil lol

 

[DaveSignal]

A single coil at 0.5 would work. But a lot of people get 26650 mods and attys to do more than that. And any high-drain 26650 battery is rated for more than enough amps to make lower resistance builds safe.

 

[Trypno]

I vape in this range because anything lower is just too hot for me. Also, this build is only nine wraps per coil for a .5ohm dual setup, not 15 wraps. Each coil in this build is only one ohm, as opposed to the 2ohms per coil in my first build. Vapor range and ohmage are the same, but the vape between these two builds are totally different beasts. As I mentioned, the build heats up much, much quicker this time around, than my quad did. No, it's not instantly hot like some setups, but I don't need it to be that hot that quick, I'm not cloud chasing, I just wanted a hobby and more vapor.
Anyway, I gotta get an ohmmeter before I can really start experimenting with builds, but thanks again for the tips guys.

Even with a 26650 I still prefer the 0.5 ohm range single coil and I like to tip my mod towards the coil to gravity feed it, I've built lower and plenty of mulit's. Even on 18650's lol I don't believe the 50amp claims of 26650's. YMMV obviously.
