Thanks mate! I'll take the advice to wrap coils as in the pic. I reckon I'll probably need couple of tries to figure the ideal wicking. Will use a juice I don't like initially for trial and error
Just a question - I'm not too fussed about the Ohm I'll get in my build as long as I get a good flavour and battery life. My understanding is that at higher Ohms (e.g. 1.8 or 1.6) one needs lower wattage for vaping? I use 13-14 watts power in my devices and battery lasts me a long time. I use Tarot nano and Eleaf's iStick power nano as my travel mods with Vika tank on it. It's an ideal setup for me as it fits perfectly in my pouch (12cm by 5cm) and in my trouser or jacket pocket just like how I used to keep Ciggies boxes and the battery lasts me all day comfortably. At home I use iStick Pico 21700 with Kabuki and the battery lasts me 2-3 days on a single charge (I charge once battery reaches 30%). I mostly use Aspire BVC 1.8 ohm coils. I had couple of Trition mini coils and I prefer BVC 1.8 (not sure why though

)
If the SS316L 28GA 7/8 wraps comes out at 0.5 or 0.6 ohms then I'll need more Wattage. Right? I'll use Kanthal 28GA in that case as I like MTL (cig-like experience) and don't want to compromise on battery life. You reckon I could go up to SS316L 30GA to get to 1.1 or 1.2 ohm resistance? I haven't tried TC yet and want to give it a shot, that's why I ordered some SS coils.
Correct -
Higher Ohms = less wattage
Lower Ohms = more wattage
So if youre running 1.8Ohms and using 13-14watts, dont be surprised if you'll likely want to try starting out around near double that for a subohm (sub 1.0 ohm) build...start around 24watts say and adjust up (most likely) or down as needed till you hit your preferred vapour/heat level. I can onyl barely remember my wattage days as ive been TC'ing most of my vape life, but not unusual to hit 30w on a 0.6ish build when i did use watts mode, of course plenty of people vape much higher wattages (and now temps) than i do, i likes me a coolish vape.
Plenty of folks prefer 1.8Ohm coils
28GA anything can be a bit fiddly to work with (SS can make it a little bit tricker to work again as it can be springier), and going to 30 is even thinner but doable, both gauges heat quite quickly, so theres that upside, less ramp up time....
It would take 11/12 wraps of 28GA 316L to get in the 1.2Ohm ballpark, and i honestly cant tell you if thats possible in the Kayfun deck, because Ive only ever built spaced coils on the Kayfun 5 deck, or any deck in fact.
If you trap the coil legs the traditional way (from the outside of one post screw to the other (see inside red arrows in following pic) there is a limit, but using the method untars pic shows (and borrowed and repeated below) you can get more wraps on using that method as its outside the screws, you prolly dont want to go (much) past where the outside red arrows are as the wick holes are pretty much directly underneath and generally you'll want to keep the wicks vertical at worst
7/8 wraps of 30GA 316L will get you in the ball park of 1.2Ohm and should definitely fit the deck even using the tradtional method of coil leg trapping (inside red arrows) -

And while im here the
very basic difference between wattage mode and tc mode, because its the easiest way to think of the difference between the two
wattage mode - the mod puts out your set wattage for as long as you hold the button, the temp however continues to increase
tc mode - the mod puts out enough wattage (from the preset wattage you set - yes in tc mode theres a wattage setting - more on that if you want to be bored) to hit your set temp, and then drops the wattage to a level needed to maintain this set temp.
Or in practical terms, if i were to vape my setup in wattage mode on 0.6 Ohms, id prolly set the wattage to around 30W for my preference. As long as i hold the button, the mod puts out 30Watts and my vapour gets ever hotter the longer i hold the button and toot it. In tc mode i set my watts to say 50W (leaving a bit of headroom in case i want to change my temp at some point - then i dont need to go back to the wattage menu and i set mine a year ago and havent been back there since) and my temp to say 195c and hit the button, it may initially put out 34watts to get up to my set temp of 195c, but then it will drop to around half that to maintain the 195c...
Like i said thats the basic wattage vs tc mode difference. Theres tiem enough another day to go down that rabbit hole, but for me, i was always struggling with a consistent vape in wattage mode, when tc came along a few years back, i tried it and never looked back, i get the same identical vape every time i hit the button...made a huge difference to me, others hate it, though i still dont understand how/why for the life of me, prolly as they dont understand how i love it so much
I tend to evangelise tc mode, so just letting you know up front....
To be fair im also a pretty decent unflavoured juice evangelist too...for testing thats my next best tip for you, unflavoured juice, just nic, pg and vg in your preferred ratio, Its all ive vaped for nearly 3 years, almost no taste - never gets too much or boring, its the most low cost and low drama (no flavour chasing and spending millions on unicorn flavours) way to vape. But especially good for testing so you dont waste your expensive unicorn juice while youre doing initial testing, you can always rotate in a flavoured juice on top of it once you know you have your coil and wick right.
