Going to build my first coil this week - suggestions welcome!

What do people use to clean coils after getting their fingers all over them. Isopropyl? Soap and water?

Either, whichever is easier to grab at any given moment. Clean with soap or Isopropyl, rinse, dry. I love those little disinfecting single-use Isopropyl pads--the easiest way to clean my vaping hardware (battery contacts, wire, chargers, etc.).

Well? You still with us? :D
ROFL!

YES!

It works. My first wick tasted a little burned because I was firing it too much on the coil master. So I made a second set of wicks. I think I might have used too much cotton, but I suppose I will know soon.

Here's a pic of me testing the coils.

Not perfect, but not awful.

That's a monster coil. Nice glow. Congratulations. :thumb:
Thank you!

Blows awesome clouds!

I had to turn up the wattage to about 90 to keep it from popping. There was a little of a burnt taste even after I rewicked it, but I think it was from the coil itself just kind of breaking in or something.

Right now it's super flavorful I'm noticing my juice has a different flavor profile. Creamier, I think.

I can see why people do their own coils and also why safety is so important too.

Here's a pic of a cloud with me behind it.

And a pic of my mess.

Ahem... not the ones I used. They were all wired in parallel. Still are--GS Air dual coils are configured in parallel: 1.5Ω coils consisting of two 3Ω coils.

Carry on. :D
Not gs air. The old cartos. The ones with the silicon tube innards. They haven’t made em in years

I have used and beta tested many cartomizers back in the day. I dissected several to check the build. I assure you that they were all wired in parallel.

What Is Atomizer OHM Resistance?
A single coil atomizer has one heating element while dual coil cartomizers have two. The two coils are of the same resistance and are wired in parallel so the total resistance is half the resistance of either coil. A dual coil cartomizer built with two 3-ohm coils has a total resistance 1.5 ohms and not 6.0 ohms. Dual coil devices can produce double the vapor and but require more battery power.

Here on ECF:

What creates cartomizer resistance?

They are still making and selling them. Plenty of people use cartos and carto tanks and like them.

Smok tech Dual Coil Cartomizers for 510

Still in doubt? Google dual coil cartomizers. :)

Not the ones I dissected. I’ll look at your link though.

Update: looked at the link. Smoktech apparently still makes dual coil cartos that are actual dual coils. I don’t think the ones I was buying back in the day were smoktech though. The ones I was using became unavailable years ago. I distinctly remember there being a single wire with two coils on it though. I couldn’t get em and was trying to rebuild one. Iirc I moved on to this ce2 clearos

22 gauge triple fused clapton twisted sleeper coil... jk
LOL,

My first step in that direction. A twisted kanthal using 2 strands of 24AWG. I had to wrap it at something like 2.5mm ID to get it to fit in the SMOK RTA.

[emoji3]

Vapes nice at only 32 watts. I actually had a juice that I didn't like, but for some reason it tastes pretty good on this. I kept wasting a lot of my "fav" juices by messing around and making different coils and having to dump part of the tank. So I started using my backup juice and it tastes almost good now!

OK

I don't normally stay up all night doing pretty much anything.

But when I do, it's usually related to me learning new things.

Here is what I learned:

If your build deck gets too hot on the coilmaster, AND you have some spilt e-juice on the 510 threads in there, it will gunk up said threads and throw off your ohm readings. I was getting pretty much random ohms readings at one point until I figured this out.

Small build decks won't take big coils. That last pic of the twisted coil is a case in point. It was working fine until it started not working fine. It was touching the little cap that goes over the build deck and my mod was telling me I had a short.

That and my gunked up 510 threads sucked up several hours this morning. I thought my RTA was defective, and it was really just two separate issues conflating in my head.

I made some more coils and learned if I reuse them, that I really need to tighten down the allen screws that hold them to the post (otherwise they read higher ohms than they should).

Also - coils with more surface area seem to make more flavor.

I may have learned some other stuff as well, but I probably already forgot it! This is fun!

I use a LOT of "Z" coils - single coils between the posts, but always on RDAs rather than RTAs. The problem for me is wicking a dual-coil RTA with a single coil. It's tough to fill four wicking channels with two wick tails coming from a single coil. And when you build between the posts, the wick tails are usually going in the wrong direction to route them to the channels.

If you want to build a single-coil RTA, I'd suggest getting one designed for a single coil - like the Ammit.

Unless I am missing something?

Ok, the SMOK Baby Beast "drop in" RTA bites. I was getting all those strange ohm readings and shorts because a post was not grounding properly.

The badder news is that the whole little device is press-fit together. There is no way to tighten either post if they start to work loose.

Suggestions gladly accepted for decent rebuildable tank atomizers, preferably 25 mm or so.

The good news is I have learned how to wind decent looking coils!

I myself like single coil so I’ll suggest the pharo25 or the ammit 24. The avacado is supposed to be good as well
