New to coil building.

[CloudsOnClouds]

Alright so I used to use an itaste 134. I just bought a sig 150 and am using a crown tank. Love this tank.

I just bought a velocity RDA and it should be coming in the mail in about a week. I have my Japanese organic cotton. But I'm not sure what gauge wire to buy. I'm pretty sure I want kanthol. I know nichrome will ramp up faster but I am allergic to nickel and I'm afraid to use any kind of nickel wire.

I want to try my hand at a Clapton coil but I'm not sure what two gauges would be best. My goal is to run dual coil and hit .1 ohms. From my research, that's the lowest I should safely go on my sig 150 mod.


Any advice on what size wires? I'm pretty sure a 22 would be fine for the inner wire but I'm not quite sure what to wrap around it.

Thanks guys!

I think 22 is a bit much. Ramp up is a concern. Not saying it's not doable, but it wouldn't be my first thought. Claptons incorporate a bunch of metal that doesn't carry much, if any current. Most of the power is going to the lower-resistance core wire (remember, current favors the path of least resistance,) meaning that the core wire also has to heat up the outer wirelargely on its own. So if you clapton around the already slow 22g, it's going to take that much longer and that much more power to heat up. And when it does, it will be very hot because there's a lot of metal there to hold onto the heat..

Claptons tend to work best when combining wires that heat-up quickly and cool down quickly. It is important that the higher amount of metal gets to the right temperature quick enough for a full vape, but doesn't hold onto heat long enough to reach excessive temperatures.

I've been liking 24 or 26 for my clapton cores lately. I find that very fine wire works best for the outer wire. It's all about those tiny nooks and crannies. That's where all of your surface area is at. I think of it like this... ...a thicker wire with fewer gaps holds less juice than a thinner one with a multitude more. 32g works decently, but isn't quite thin enough, heats up too slowly, and retains heat for too long, imo. 34g or 36g is where its at.

With these guages, 0.1 ohms is too small of a coil to get good performance. Shoot for something in the range of 0.2-0.4. A little tip for calculating the wraps: claptons ohm out about the same (if not slightly higher,) wrap for wrap, as the core wire alone would.

.1 is the lowest you CAN go with a Sigelei 150, and you are correct in assuming that it is safe for 30-amp batteries, but that doesn't mean you should build that low. It's pointless and counterproductive to build to resistance on a high-powered regulated box. It's not as big a factor as the size and heating properties of the coil are.

Think of the coils you build for it in terms of how much surface area you want for a given power level and go from there. The idea is to balance out the amount of surface area with how long it will take to heat up within the wattage range it's usable at. It takes a little trial and error. I think you'll be surprised at what some of the coils you wind up liking more with the 150 actually ohm out to.

Wow! Way more specific than I expected. Thanks


So I'll try a 26/36 Clapton and see how that works. Wire is so fucking cheap I can just buy a whole range.


I'm currently at .25 ohms. So I should try to build .4-.2 for optimal clouds? I still have my tank for flavor so idc how it tastes as long as it's not burnt.

Haha, np. Just tossin some general build theory at ya. I'm sure others will have some more specific recommendations for you.

26/36 is a great place to start! Happy clapp'ning.

You can conceivably go lower than .2 and get decent vapor production. It's just that the lower you go, the less surface area you have vaporizing juice. It'll heat-up faster but won't be able to heat as much juice. After a certain point, you'll be trading vapor production for heat.

Something in the range of .2-.4 is probably going to give you better vapor production at an all around more bearable temperature. Low-end of that for 24, high-end for 26. I think you'll probably find a sweet spot somewhere in there. You may even be able to go a bit higher than .4 with the 26 and still get pretty solid vapor production. Can't say I've ever tried myself. This just the range that I feel I get the best results from.

By all means, do experiment with it for yourself. A lot about the vapor production is going to depend on your vaping style and how much heat you can handle.

Also, buy lots of the thinner wire. You'd be surprised at how quickly a 100ft roll is spent, even if you're being efficient with it.

My vaping style is good for sure. I could throw more clouds at 12.5watts than my friend at 40 watts.


And I guess ridiculously low ohm builds are pointless for regulated mods.

Well, not entirely. It's just not the focal point. It's all about the size and heating properties of the coil. You could run standard dual 22's at something like .18. Dual-parallel 24's at .16. Or maybe even some dual 20's at .14. All of these are pretty low, but it's more about the fact that they are BIG and can rapidly disperse a lot of heat at high power levels.

Well I just went on a shopping spree. Ordered a Delrin acrylic tip. My lungs can handle 150 watts but my lips can't handle it with a metal tip. Then I bought some 26 and 34 gauge.


All that and the velocity RDA Should be here next Thursday! Super psyched.
