Dual coil build around 1.2 ohms, gauge ect.

[Zombiewoof]

OK, I've been building single micro coils on an Igo L for awhile now. I would like to dual coil dripper and have narrowed it down to a few choices ( usual suspects, Tobh, ect. ect. ). I'm not interested in doing sub-ohm builds right now. I drilled out the air hole on my Igo to 1/6" and have been using 32ga Kanthal with cotton wicking. It performs pretty well and I've been happy with it. I'm not sure whether I should go with 28ga (more wraps) or 30ga. I usually run around 9 watts ( mech with a kick) and would start out with simple dual micro coil builds on a 5/64" drill bit. I guess I could go with a bigger inside diameter and do less wraps but without any real experience I guess I'm not sure. I know I could try a dual coil on the Igo l to experiment with, but I really don't want to drill another hole in it. If I figured it out correctly, 28ga duals would be something in the area of 16 wraps per coil. Is that going to be a problem size wise in a 22mm size atty? I guess they would be horizontal coils, unless vertical were more practical. If this is all too vague, I apologize in advance.

Too vague? Ya' think?

If I understand you correctly, you want "above an ohm" - dual parallel, 28 gauge coils, built on a 5/64" (1.98mm) mandrel. That would be a pair of 8/7 wrap coils... for a net resistance of 1.2Ω. This is calculated on Steam Engine, using a 5mm leg length. YMMV.

I'd dispense with the Kick, and just run unregulated... 1.2Ω at 4.2v will have a current draw of only 3.5 amps.

i use coil toy all the time to help determine the ohm build i am aiming for. It is awesome
I wish they would add a pull down option for special coils like twisted and clapton though.

I was thinking about two coils instead of one when I thought 16 wraps. So my mistake. Thanks for the help. I'm just use to 32ga being so thin that having nothing to compare it to I wasn't reallly sure on clearences ect. Since Kanthal is so cheap Maybe I should just by some 30 and 28 and see which one suits me best. Yes you are correct, I'm not looking to sub-ohm, at least not right now. Thanks for the link to Steam Engine, I've seen it before but never bookmarked it. Also thanks for the link to coiltoy Dutzy.

Yeah I do too. I don't mess with claptons but for twisted it's been trial and error for me. I just keep a little notebook when I build the ones I like.

Sooooo, I picked up an Igo-w today for 13.99 US and what I found was this, A dual parallel ( NOT dual parallel coils ) but two coils in parallel ( 28 gauge kanthal using a 3/32's mandrel ) came in at 14 wraps per coil for a net of 1.2 ohms. That being said, I decided that 14 wraps was a little big and was really too much resistance for the Igo-w and built my first dual coil sub-ohm build at 10 wraps per coil which came out to .9 ohms. which performs quit well and produces a lot of vapor and flavor. I'm not comfortable with going down past .8 ohms, and even .9 is a little iffy for me. 8/7 wraps per coil would have been around .6 ohm net...not really the answer I was looking for.

doesn't matter...Happy dance involved

I'm running 2x 28ga 10wrap now in a tugboat @ 50W in my box mod. About 1.1ohm. It works very well for regulated boxes but on a mech it leaves something to be desired. Glad you found something that makes you happy dance!
