Tried even smaller coils @ 1.5 but it was dual coils 32 Awg. Turned out good. Onto bigger coils next. I guess this thread died eh?

Stricktly using 28g wire on 1/16th drill bit for a while. Solid vapor and flavor, just the right throat hit. It's been a long road with a lot of coils and testing but I think this is my go to coil until I get motivated to try this again

I would LOVE to know the results of this experiment. Have considered doing it myself, but I only have a 1/16th, a 5/64th drill bit and a 20 gauge needle that I use for coil builds. Not really a large enough sample size to get solid results.
I have wrapped many different diameter coils. The largest being around 1/8" with 4 wraps and the smallest being around an 18 ga needle with 15 or so wraps.
I have found the best setup to increase VTF to be a proper micro coil - 10-13 tight / touching wraps around a 1.4mm to 1.6mm mold / jig / mandrel with a rolled cotton wick. My jig size of choice these days is .055". I suggest 1/16" - it's very close.
Any larger than 1/16" and the traits of the micro diminish, any smaller and it's a pain to wick. I wick thru the center of the coil because it suits my vape style.
I suggest using the size wire to hit your target resistance in 10-13 wraps. For 1.5 ohms I use 28 ga. For 2 ohms I use 30 ga.
A proper micro coil has the surface area and concentrated heat to make quick work of vaporizing eliquid
Here's a pic of my typical 28 ga build:

Thanks for the heads up, even a 1/16th coil is a little tough to wick for me. I'm using sugar and cream cotton yarn boiled. I wick through then coil on my rdas, bout externally on my kayfun. Still sticking with the 1/16th in my rda but can probably go smaller in my kayfun, but I don't want to use 30g to get my desired ohms, I prefer the durability of the 28. It makes a big difference for me.
I'll be going nowhere but down in diameter from here, though. as I feel 1/16th is the smallest I want to go for coils with wicks going through them. Still need time to experiment. next coil in kayfun will be smaller

Sticking with 1/16th still. Only reason I can think of to go bigger is thicker juices... Maybe.

So if your running 10+ wraps around a 1/16" drill bit. I take you guys are using 28g? If I tried that with 32g kanthal wire, I'd end up with a 4ohm joke. ;-/ Is that correct?
I found this here... That coil spreadsheet looks to be very helpful. Should be a sticky!

28 Awg kanthal is standard for micro coils imo

Yep It is for my target resistance of 1.5 ohms.
But on my VV I shoot for 2 ohms. 29 is my favorite for that.

My problem was this...
very small diameter with more wraps or larger diameter with fewer wraps, both yielding nearly the same resistance. The smaller diameter coil having a thinner piece of cotton within it would not reabsorb quickly. The first toot would be great, the second not so great and the third is dry.
The larger diameter coil would allow more cotton and thus more juice. I didn't dry out but the the trade off was vapor production and flavor. Was it unacceptable? well it was for me... that's personal.
What I did... Realizing that I need the larger diameter coil but I also needed the same overall length of coil that the smaller diameter coil yielded, I needed lower resistance wire. than the 28 ga I had. Rather than order a thicker wire I twisted two 28 gauge wires together. The has the same effect on resistance that going from one coil to two coils does in a Dual coil atomizer. The difference is that you still have one coil. The gave me the ability to make a coil that was both wider in diameter to accommodate more wick and thus more juice, but also allow me to have a coil that is just as long as my very small diameter coils.
Pros, larger coil, with the same resistance as your smaller single wire coils.
Cons, tricky to make for first timers, Takes longer for the coil to glow when firing naked, takes longer for the coil to cool when current is withdrawn.
Remember, Creating big clouds isn't just about low resistance. You have to be able to supply juice to the coil and move vapor away from the coil so new vapor can be created. Heat, juice and air!

The diamond build like in Rip Trippers vid solves the slow wicking through 1/16" coil for me; has it's pros and cons.
My coil of choice is 3/32" ID twisted 30GA; easy, fast wicking, durable, big clouds and quality vapor.

My 1.4 ohm diamond on a mech is too dang high. 0.7 ohm (20 watts) should perform like Rip's.
IMO stick to the keep it simple function over form. 8 wraps 28g on 1/16th @ 1 ohm is working amazing

I use simple 8 wrap 1.2 ohm 3/32" ID twisted 30GA single coil most of the time.
Fancy coils just for kicks.
