A couple questions before I embark on buiding coils

[twolostminds]

I've got the itch to start building coils. Rebuilding them for my Nautilus and going to take the plunge and get a Kayfun 3.1 clone. (shhh, don't tell my wife <.< ) lol

1. If I understand it correctly it takes more power to heat up a 1.2 ohm coil than it does a 2.0 ohm coil?
2. If 1 is true, then lower ohm coils eat up battery faster because you require more V/W's to heat them, correct?
3. Lower ohm coils give a better vape or taste?
4. Round or ribbon kanthal? I think round because ribbon has edges that will heat up faster than the rounded coil,correct?
5. Steam-Engine has a great looking calculator for coils. Is this the go to coil calc for newbs like me?
6. I primarily want to build 1.2 - 1.6 ohm coils with as much coils surface area as I can stuff into a Nautilus coil and KF 3.1, is 38 gauge Kanthal A1 round the right wire for me?
7. Ekowool silica or Silica? Which is better? Also, 2mm seems to be what I've been seeing in video tutorials.

Sorry for all the questions, just eager and don't want to make more mistakes than I have to.

1. Yes.
2. Yes.
3. Mostly... but taste and flavor can be subjective. Lots of folks, experienced with lower resistances, still prefer a cooler vape.
4. Subjectivity again. Round for me... it's just easier, although I did experiment with ribbon back when I was into gennys. Your "edge heat theory" isn't really applicable or relevant. Perhaps on a larger scale than the iddy biddy wire we use. ;-)
5. See my sig line... 1st or 2nd one, doesn't matter, either will get you there. Currently, IMO, SE is the best coil build/Ohm's Law/battery drain calculation site on the net. I must recommend it at least 4-5 times a day.
6. 38!?!? If that's not a typo, then no brother... more like 28, 29 or 30.
7. Subjective, but of your two choices, I preferred German silica. I stopped using either of your choices last year. 98% cotton user now...still playing with ceramics and hemp fiber on occasion.

Yeah 28 LOL That's what I get for posting while working the BBQ

I'll take a breast, some slaw, two ears of corn and a half dozen ribs... thanks.

I've also got some Memphis style smoked brisket that was smoking for 6 hours and a bucket of ice cold beers if your interested.

Alright, you have quite a few questions there. I'll try to knock out a chunk of them but I don't know the answer to all. Ill start with number 3, lower ohm coils do not necessarily give off a better flavor. For example, the best flavor I have gotten is out of my kayfun which I build between 1.0-1.5 ohms regularly. As far as vapor production goes, It doesnt even come close to my dual coil set up with flat ribbon wire wrapped around round kanthal 30g at .5 ohms. That thing is a beast vaping at 30 watts but obviously if you are going to go with sub ohm, PLEASE read up on battery safety. There are plenty of threads on here that will teach you everything you need to know.

As for number 4, I do not have too much experience with ribbon kanthal, I have had a good experience with standard kanthal so you really cant go wrong with sticking to that.

for number 5, If youre looking to rebuild your coils your best bet would be to just buy an ohm meter, thats the safest way to go

and for number 7, I personally do not use either of them. I strictly build all of my coils with cotton, in my experience I get the best flavor and never have issues with dry hits

Hope that helps

Folks got most questions answered, just a few things. Power (Watts) is what determines the heat the coil generates. So for any given resistance coil you can change the voltage to get the same power. How far you can adjust the voltage is limited by the current available which is a function of the battery and the circuit for vv/vw devices. You can generate 10 Watts of heat in both a 1.0 and 3.0 ohm coil but the amount of current needed is different as is the voltage. It'll be easier on the battery / circuit with the 3.0 coil. Easier means better battery life.

If you want lots of surface vs amount of metal you can quite simply use twisted wire, ie. use 2 strands of 30 gauge instead of a single 28 gauge strand. About the same resistance but much more surface. And it's easier to use than ribbon (flat) wire.

1. Yes.
2. Yes. It also burns through juice faster.
3. It depends on many factors. It's all very subjective. Some juices I like a little warmer than others.
4. I've only ever used round and it works great.
5. Use that calculator (Steam Engine) EVERY TIME YOU BUILD A COIL. Even if you know your setup, it's always a good idea to make sure. Then test your coil on an Ω meter.
6. 28g is perfect for that range in a Kayfun (I've never recoiled a standard tank head). You'll be in the neighborhood of 5 or 6 to 8 or so wraps on a 3/32" drill bit (2.4mm) to be in the 1.2Ω-1.6Ω range.
7. I only use organic cotton. It's cheap, and the flavor is maximized. The down side is having to change it out every few days (some change it out every day - which I think is overkill - others change it every time they fill the tank, and still others do it only when it starts to taste off which will depend on how hot your burning the coils and your juice).

Hey everyone, thanks for all the comments and input. A few of you have recommended organic cotton and I've seen some rebuilds on YouTube using it as well. Is everyone using cotton balls/batting and making their own wicks or is there somewhere I can order some braided organic cotton wicks for ease of use?

You don't need to braid the cotton. just tear a piece that when rolled can slide in the coil with just a bit of resistance. I wold recommend boiling the cotton before using it. I use sterile cotton from CVS ($4,00) a box that will last a long time.
