You mentioned wrapping on something with a 1.5 diameter that's smaller than wrapping on a 1/16 drill bit. I only use 22, 24 and sometimes twisted 26 gauge. If you wrap that small your cotton burns since it doesn't wick fast enough and only a small amount of cotton feeds through that size coil. Even if the outside doesn't look burnt the inside of the cotton under the coil will turn black.

Are you trying to build around .3 or are trying to go a lot lower?

First off, for those who where looking for a conversion from fraction to millimeter etc. FRACTION TO DECIMAL AND MM TABLE

Bigger diameter of what you wrap around plays a part in heating too. I like my coils wrapped small at a 1.2mm diameter and 9 wraps with 24ga. Sometimes one will heat slower than the other, play with them making sure they are evenly spaced all around. If you're using an atty with one center post, make sure you have a good hold on both wires with the screw too.

Some pics of my favorite setup atm. 24ga 9 wraps around 1.2 comes out to .25 and is medium heat.

Yes, I build on a 1.5mm post, and I specified that it's between 1/32" and 2/32" (1/16") in one of my last posts, and there is no burnt cotton. Not even when I remove the wick to rewick. It's been my go to build for the past two months. What matters is coil to cotton surface area, as long as there is enough juice being supplied to the coil, there will be no burning. There are a lot smaller wrapping posts than 1.5mm used for smaller microcoils and nanocoils. These builds wouldn't be popular if all they did is burn cotton.

I agree, in the pics of my setup above your post I used a 1.2mm dowel and wicking is no problem but can be tricky. You need to make sure its not tight, but not loose. Also because it's such a small amount, they have to be almost identical wicks ( diameter wise ). Or one will quickly dry hit before the other.

Exactly. It just takes a build or two to get used to how it needs to be wicked but it's my favorite build so far.

How low do you build and do you take lung hits? It makes a difference when you're going low,, the OP asked about 5 wraps of 24 gauge that usually is about .2-.24 and taking long lung hits will get you burnt cotton. Maybe you're style with higher ohms and shorter hits isn't a problem, but usually when people go for lower ohms they're taking longer hits since they're most likely trying to get better cloud production.

I run similar to his, I run 24ga around 1.2m @ .25 ohms and take long hits. Not do-able if your wicking isn't right though. I drip 12 drops every 6 hits or so. ( I chain vape btw )

So I built my first and second coil and followed rip trippers instructions for the sleeper coil came out looking beautiful, pinched together and even the ohm reader was reading .3 but it just doesn't heat up fast enough???

You do know your build was fine, right? You just had a low voltage battery. LOL

Probably you guys use a lot more cotton. Like a lot of the cloud chasers I know we use minimal cotton and get 2 good lung hits about 6-10 second pulls. No where near 12 drops or .25.

Well this is off the OP's topic so let's just agree that your way can work for some vapers but not all.

I have no problem agreeing to that :D I do use minimal, letting about 1/8 inch hit the deck out of each of the coil sides. I figured out a while ago that cotton only holds the juice, the heat is what sucks it up. That's when I started making sure both sides where even on the wick.

Sorry for the long reply just wanted to give Cullen the major thank you to a great coil buildView attachment 363132 seems to be working rather well at .29 went a tad bigger with a 1/16 drill bit

Good! I'm glad it worked. My pleasure, enjoy buddy. :) Just make sure you change that battery more often okay?

I don't know how you get so many hits of that kind of build. I'm lucky to get two 7-10 second pulls without a partial dry hit, but then again all my builds aren't something an average vapor or normal sub ohmer does.

What do you build at? Coil specs? I usually get 5 delicious pulls then a 6th dry-ish one with my build.

Well the way I look at it is like this: The juice is free to fill the decks " bowl " up. I used to use a lot more cotton, but started noticing the cotton around the coil was wet, and my coil was still getting dry. So I started cutting back cotton until I found a comfort zone. The juice is still there, it's just not stuck in the cotton until it's needed I guess.

Usually 22 gauge A1 kanthal or Royal wires 4-5 wraps on a sleeper build. Twisted 24 gauge A1 kanthal or Royal wires 4-5 wraps on a sleeper build. Dual parallel coils on a sleeper build using either 24 gauge or twisted 26 gauge kanthal or when I'm really bores I'll do twisted something gauge on a parallel build using a sleeper build with nano dragon coils or micro coils set up like nano dragons.

I can't use the drip well like a lot of cloud chasers I know, since there's spit back and at low ohms and hot liquid doesn't mix.

Kinda forgot about drip wells.

I had that problem especially with the drip tip I use ( wide bore one from cherry vapes ). I ended up raising the coils as high as I can get them without touching anything. Leaving some room from the pool of juice in the well.

I always have my coils centered to my air holes and another reason why I can't use the drip well is because of my drip tips and all my air holes are drilled out to 1/8 or 9/64.
