First attempt at my own coil, would like some tips

[Markill]

Today, I managed to make my first workable coil. 26g kanthal wire, 10/9 wraps around 2.77mm, 1.3 ohms, firing at 11 watts. It takes a really long time to heat up to actually produce much vapor, and even then it's not giving off as much as the one a shop made for me. I can't go below 1.2 ohms cause I'm using an MVP 2. Any tips to make it better?

Use thinner wire. Try some 28 ga. Thicker wire is lower resistance and takes longer to heat up given everything else is constant.

since I see an MVP in the picture.... consider going with either 30 or 28 ga....

Mark, you might get something out of this video I made for another thread about Kayfuns.

I see you are using a W type dripper. For a dual build @ ~1.5Ω you would need to use 7~8 wraps of 32 ga Kanthal on a ca, 2mm form. Try a toothpick or the little blue screwdriver that probably came with your atty —the toothpick is easier; cut it in two and use half for each coil until you have them secured and tested.

Hang on and I'll be back with some pics in a few minutes.

That looks like juiced cotton to me...

I would have probably set it up with 28 ga. Kanthal on a 5/64" drill bit for either 8 or 9 wraps pulsed/torched and squeezed together.

It looks the same to me. Coil is sitting on top of his cotton.

yup I had some pinkish juice in there. And I was just in a hurry to get some wire, and my local vape shop only had 26g. If they had 28 I would've gotten that. I'll check there in a few days and see if they've got anything else. The atty came with something ridiculous like 34, that coil wasn't even worth the hassle it took to build it

 

[ForeverDiving]

In my haste I grabbed the Kanthal 30 so my build came out at 0.94Ω. Use 7 wraps of 32 ga x2 and you will hit the 1.5Ω spot.











Leave your leads a bit long so you can wrap around the post screws easily, until you get some practice; then clip. Wire is cheaper than time.

Is dual coil worth the little bit of extra effort? I was told not to go dual coil on my MVP but it seems as long as i keep the ohms high enough it shouldnt be an issue

 

[ForeverDiving]

Don't choke the atty with cotton.

Tuck the tails under the coils

Juice all over but chek it doesn't drip out.

Test and that's all.

Dual coils on that atty (3 post configuration) will give you a more even performance and more vapor. However, if you prefer, and for that resistance value ( >1.2Ω ) it probably doesn't matter. I did that because I wanted to show you how fast you can coil a dual with a little practice. Don't dispair.

@Markill, you'll want at least three gauges for different builds, 32, 30 & 28.

Make sure you verify your dual coil setup isn't pulling too many amps as well, don't recall the limit for the mvp off the top of my head, but you may need to build dual coil up to 2ohms to get good performance. At 2 ohms, use 32ga wire... 28 coil at 4ohms (dual coils cut your resistance in half) would be giant, and my not fit in the atty.

A good solution is to increase internal diameter (ID). No way to do that high Ω with 28 ga but 30 will give you a 2Ω dual (4Ω ea.) with 11 wraps on 3mm. Huge but manageable on a 22mm atty. It will suck juice like a 6mo calf tho.

32ga is the recommended for 1.2 to 2Ω. a 2mm coil pair should work pretty well. OTOH, a mech atty (one of those $20-odd Nemies are great) will fit a three post atty like a glove. I love the Origen v2 and the Helios but if I were buying now I'd get an Infinite CLT.

PS, calculator here.

I actually had a tough time fitting my first (failed) attempt at a coil in this atty as well. At this point I'm just gonna need to get more wire it seems.

another solution is to get a higher wattage regulated mod
If you can get by with a single coil on your atty with the MVP I'd go that route personally. Just not enough power for dual coil setups IMO.
