Coil wires touching and not touching

[silkakc]

I've watched tons of coil making videos. I was wondering why some coils can have the wires touching and some other coils you are supposed to make sure the coil wires are separated?

What kind of builds are you referring too? Single coil, dual coil, two or three post attys?

I don't particularly care for the tightly-compressed coils; they seem to concentrate heat extremely, leading to burnt wicks and dry hits. I just try to wrap them close enough together that compression isn't needed just to make them "fit" wherever they're supposed to fit. But then I don't get this high-wattage vaping either, from 11w up to like 30w, or the sub-ohm thing; I can't figure out how they don't set their face on fire with such an extreme amount of heat, and it's a complete mystery to me how any wick can stand up to that.

I just bought the 50 watt IPV2 and thought the same thing until I finally got coils built that could withstand the wattage. Definitely thought it was pointless. I was getting big clouds but the vape was very hot, and would burn after more than a few seconds, just not pleasant at all. I started experimenting with help from here, and lower gauge wires with bigger diameter makes a world of difference. I had a 32 gauge nano coil built already when I got the device, I tried it at 25 watts and it burned the wick and my throat instantly. Much better luck with 26. Through trial and error I was able to build micro coils that produce vape that is no warmer than it was with my MVP2, but much more flavorful and dense, and can hit for as long as necessary without burning.

As for being able to withstand extreme heat, if I had to guess I would say that my 26 gauge 1.3 micro coils or dual coil .7 at 35-40 watts burn with less heat than my 32 gauge nano coil did on my 15 watt mod, I feel like the gauge and resistance has more to do with heat than the wattage. Thats just my experience though, and I'm probably wrong haha.

For the OP, its all just a matter of preference. A lot of people prefer coils that don't touch, a lot of people don't. Both builds have pros and cons.

Given the same resistance the smaller gauge wire will heat quicker. That's why you can get away with lower ohms on the heavier gauge, the coil temperature doesn't get too hot while you vape.

Hmm... I guess this would explain why I find myself reaching for the 29ga all the time anymore, rather than the 30ga; I like a warm vape, but not hot. I also like that 29ga is just marginally sturdier than 30ga, but doesn't take as many wraps to get to my preferred 1.7 or 1.8 ohms as 28ga takes, and heat up somewhat faster than 28ga at that resistance. The 29ga coils I've been making seem quite sturdy, won't deform no matter how much rayon I try to shove thru them.

This is also what I have found, with the correct airflow, a thicker gauge, lower ohm ed build seems no warmer to me then a higher resistance thinner gauge build. In fact, I feel if I vape a 30g build, it's way more harsh then my 26g builds.

I suppose it has something to do with water never going higher than 213F at sea level at 1 Atm of pressure
