I want to build a dual-coil to use on my VV/VW, so I need to keep the ohms up. Which gauge would likely be best?

Yes: are those numbers for the individual coils or the double build?Need to clarify if the op wants the individual coils in that range or the entire build. If it's the entire build, won't the individual coils need to be 2.4 to 3 ohms?

On a 5/64" drill bit a 3 ohm coil requires:
30 awg - 7 wraps
32 awg - 12 wraps
Two of either together will give you 1.5 ohms
This is *very* interesting; in the next few months I expect I'll get brave enough to try and learn to rebuild mine. What if I want to do a single coil, and have the ohms come out to about 2.2-2.4? I don't like it too low, it gets too hot, but not too high either, so I don't have to max out my vv3. The coils in question would be either those for the T3S/MT3S, or the mini protank II, which I believe are the same coils as the Protank and EVOD. What gauge wire, and how many wraps?
Thx!!!

Around 11-12 wraps of 30AWG, or 8 wraps of 32AWG around a 5/64 bit should get you to where you want to be.
Thank you so much!!! I've copied that to a text file so I don't have to go hunting for it, when I get ready to do this. Which of those would be the absolute easiest, for a total newbie to all things electrical?
Thx again!!

No problem I find the thicker the wire, the easier to wrap so would recommend the 30AWG. Good luck!
Excellent, and I would have to agree; I find a lot of these lil teeny things to be nearly impossible to grab/hold onto. So now I know what kind of wire to go hunting for.
I realize that my iTaste vv3 can function as an ohmeter to test it after it's built; are there any other specific tools that would be necessary/helpful for this task? I've got a screwdriver that I've always called a "geek tool" -- flat at one end, phillips at the other, and very very tiny -- originally it was a tool I used for computer stuff, hence "geek tool". My husband has got wire cutters of all kinds. Anything else? (already got the P&C yarn)
Thx!

All I use for coils is the wire of choice, wire cutters, drill bit or similar to wrap around (I made a simple jig for this), butane torch and tweezers. Nothing beats stocking up on your own hand built coils made for all of about
Hmm, don't have a torch... what's that for?

Sorry, I'm in microcoil mode, I've wound about 30 today! For rebuilding heads you can get away without using one, but for microcoils using this thickness especially it's a good tool to have. It makes winding a coil much easier. Once you have cut your length of Kanthal, slowly run the flame along the wire and it should glow bright red as you move it along. This will anneal the wire so it's much easier to shape.
Best thing to do is have a go at rebuilding a couple. If you have trouble forming the wire because of the natural springiness, a torch will solve that problem for you.
Ok, well good to know I probably won't need it. My husband has been privy to all this, since he's a "real man," he loves those man toys. He says he wants to get a propane torch, not a butane; would that be usable, if/when I ever do the microcoil thing? Those are mainly for the dual-coil type atomizers, right?
Thx

You shouldn't need one for the build you're going for. As much of a man toy a propane torch is, it would most likely just ruin a wire as fine as that. Tell him even these little butane torches are pretty ferocious little things, mine pictured below sounds like a jet turbine at full throttle
Yes microcoils can be used in dual coil set ups, but I normally prefer just a single coil. With the gauges of wire I currently have, I can get as low as 0.7 ohms with a full 10 wraps or as high as 2.5. They're pretty versatile! Also great for the likes of Kayfuns. For any wire smaller than around 25AWG I find it essential to torch it first. The coils simply won't wrap neatly together while that springiness is still there.
