OK here is the twisted 32 gauge I promised.
To wind the coil I used about 12 inches of 32g kanthal, doubled it over a small brass pot with handle, wrapped the open ends a few times by hand, held the hand wound wraps with pliers, suspended and spun the pot until the wraps looked tight.
Wraps: 7
Ohms: 1.7
Wick: Cotton
Flavor is best I have had on Mini ProTank 2, power handling is beastly, vapor production varies on power.
The low end of this coil is 7 watts, high end is 15 watts.
Quality of the images isn't great but you get the idea. Keep in mind this is my first twisted build and compressing this is difficult.
The first image is before I pulled a wind off to tighten the wrap. I used an EVOD base while building since I have several not in use.

Nice lookin coil you got there. I need to practice making coils... I have a Protank 2 Mini which I really like but I feel like the flavor/vapor could be more. I am really terrible at making micro coils though. The ones I have tried to make are always lopsided and the resistance keeps changing or it doesn't fit well inside the base. I bought a wiring gizmo, hopefully this will help me make better coils.
Thanks, it's not too bad for a first go at a twisted coil but I hope subsequent builds will get better. The twisted kanthal is very firm and springy.
The first image you can see I cut a piece of bamboo that was laying around then drove a small copper coated finishing nail in the end, finally snipping the head off the nail. I used another nail of the same type for positioning the coil in the head.
I really need to make an actual jig instead of a 'wrapping supplement', I have large fingers that just don't do well with these tiny coils.
Purdy. Great tight twist on 32. Threw one in one time on a KPT. Couldn't get it to terminate properly. So congrats. With twisted calculating the res. becomes even more important. Love to know the Ø for the nail on that tool bit f1ve. LMK if you can mic it. Watch that left side in operation. If they're not all touching; well, they need to be by themselves. Or it'll go hot on ya. Talk about dry. Well you know. Easy to do with these twistties. Yikes, you can tension these little mini beasts into contact coils. Difficult to induce the effect, they're unpredictable, but doable, even with ribbon twists. Your tight twist will give you more consistent wraps and union on the turn segments. Playing with tension as you do it gets you better finishing alignment. At times the only way to neaten it up. It's really the kind of wind I'd rather do on a fixed platform than a hand held mandrel, to get it just right. Workin on that. I'm just using a stiffer screwdriver at the moment for these.
Get up a couple of batt/tanks with that and a 28 wind side-by-side. See which produces best for you. They suck a lot of power and juice. Gotta say. The split pairs I'm workin with now in drips drain the juice budget but lot's of vapor, certainly. One unreal at almost 2Ω. Keeps me busy tryin' to figure out how to bring the nic levels down on everything. Got more bottles now for everything than I can count. Let us know how that PT blows.
Have fun!

I adjusted the coil after I put it on the PT base so it's spaced the same.
The coil is a juice drinking machine, my tank bubbles like crazy while vaping due to the heavy wicking.
I don't have a micrometer but the nail used is a 3/4 inch #17 weatherstripping:

Have completed a few runs of two-strand braided 32g kanthal now and while I am very happy with it's performance I will say it's a real mother****** to work with. It has a resistance profile very similar to 28g which is handy because I'm out of 28g, but it is springier which makes it a bit more of a pain to get nice and tight and maintain shape without heat (and I applied a generous amount of tension when wrapping it). Having said that, it definitely gives off a different flavor profile which I have attributed (completely unscientifically) to the larger surface area presented by the textured surface of the braided strands. All told, I'm very happy with it so far.
Yes it's quite stiff and springy. Flavor is nice, you can also throw all kinds of power to these.
Note these twisted coils aren't great for low power dainty eliquid.
Tobacco is great with this, Hawk Sauce is not so good as it doesn't do well with high power/heat.

True that. Different! So much so that I'm considering it as an alt for ribbon on the Immo's. Running different permutations — verticals, horizontals, splits — to see how that works with different juice varieties. So far I'm liking the verticals. Been looking at Lance Wallen's vertical dripper for some time (steam monkey). Maybe sending back some of those 32's into the Protank. Try and save 'em. You never know when they might come in handy.
Good luck.
Pictures!
First, the coil prior to installation:
Then, installed:
The specs:
2-strand braided 32g kanthal w/ 14g diameter, horizontal contact coil (at least as much as possible with this media) wicked with boiled cotton.
I think I'm in love all over again.
Edit: Oops, forgot to mention... resistance came out to 1.5 ohms

You guys and your twisties, lol I really gotta get some 32 or 34g and try some!! Mac, thanks once again for the tables and great research.. These tables are so great, so many people will look at these to figure out their target resistance for their build. I do my best to contribute, but only have my eVic to validate things. ^^Was going to ask you beck's question as well.
Right now I'm rocking my usual 1.9ohm micro, 10 wraps of 30g on a 1/16"/1.58mm bit. Starting my second tank full (PT1), without changing the wick even though it's pretty wrecked from my darker/rich juice.
.... But I gotta say, I've been craving another lower-ohm, 28g build like I did about a week ago (like becks!), hah

I am somewhat new to rebuilding my coils...I have yet to master the iclear (I don't think it can be done without the non resistance legs, at least not consistently). I just wanted to thank...so many of you...it would be unfair to say a specific post as I have read soooo...many, for your work on the kanger style bottom coil atomizer. I just wanted to post a big step...for me...
I just did a VERTICAL! I used 28 g kanthal and cotton on one (10 wraps+-) and the exact same w/1.5mm silica on the other.
the assembly was surprisingly easy considering how I have struggled with some other coils! Once you get the long (neutral or -) bend down its a lot easier to wick. I learned the hard way you don't need a center "flavor" piece. Just a bit around the outside to "slow the flow" so to speak. Been vaping both all night in an evod and a mini pro 2. Just refilled both...
Really nice vape consistant for at least 4 rapid puffs (nothing I have ever used does much better, for some reason it gets hot or dry or burnt or sputtery...it's best to use 2 or 3 in rotation when chain vaping).
Thanks again...more to come as you all teach me.

Hope that pic looks better on a big screen jeeesshh! Also, on the twisted coils, how do such long strands of such thin wire give such a low resistance? Don't laugh I did say I was still a bit new at this.

Higher gauge wire has greater resistance per inch than lower but when tightly twisted the resistance is halved.
I'm not sure of actual numbers but let's say 32g is 1ohm per inch, twisted 32g would be .5 per inch.
So, in effect, creating a dual coil? Or a different gauge? Kinda the same I guess...o.k.
On another note I was mistaken...the vertical I built using silica has taken chain vaping till I put it down...more than once! I...like it...

First business, heads up! The theoretical wire length for your build (getting back to that 1-Ω diff) is 2.877 inches. Per TEMCO's rated res. of 8.36Ω/ft. your target was 2.00431Ω. My published validated (multi-build, multi-metered) spec some time back for a conventional, no strain, contact coil
30AWG, 10/9 1.58mm i.d., m.c. = 2.04Ω √
Watch for the incidentals. Just sayin'. Hope it's vapin' gooood (and it's your meter!).
Speaking of scary resistance I built this contact ribbon wind for the Immo, tensioned/torched/quenched/clamped variously over 24-hours, then after tightening it into the set and pulse burn in and I'm almost afraid to drop it in.
I don't want to fry the insulator on a black one!
What do you think???
Good luck.
