Got some nickel wire and a coil jig today. Made a 7 wrap, 2.5mm diam coil with 28 gauge nickel wire and put it in my Kanger Subtank head with KGD cotton wick.
It started at 0.15 ohms and a couple of draws later it dropped to 0.13 ohms, where it's stayed for the next 40 (approximately) draws so far. It's vaping well, MUCH better than the prebuilt 0.15 ohm OCC nickel heads. I'm using 370 degrees and 15 watts on my Heatvape Invader Mini. Only after looking at the picture do I see that two coils are touching, but it's working well and I won't mess with it until it's not working right.

Looking good for your 1st nickel build. That stuff is soft and squishy. I wouldn't be concerned of it dropping Ωs a bit as long as it stays stable. As to the touching coils - I use a sewing needle inserted gently between the touching coils. 1st from one side, then the other if need be. You can control how much you open/separate the coil wrap depending how far you insert the needle. That works well for me w/ nickel and kanthal coils spaced wraps that are too close.
Good evening porchfam, it's me again once again, I have some new info on my dad and we've had some epiphanies and breakthroughs/realizations.
He's a lung-hitter. He's part of that tiny population that drags off a cigarette straight to the lungs. What's more, he's a "holder-inner" lol... he doesn't do a strong exhale. He sort of holds in the smoke. I realize he's in maybe the 1% of smokers, this shocked me too, but after working with him and a lot of trial and error we've now at least figured this much out.
This makes the evod type setups he's using pretty crappy, the airflow is almost non-existant. I need to get him a good lung hit type setup with airflow and vapor, but he's slow to learn with new things like this(trust me I try very patiently.) He needs a device with no external battery and simple controls, good vapor and not a hot vape. Maybe a Cool Fire IV plus a decent tank? Sorry I'm rambling but I just wanted to share that we figured out why his vaping was less than satisfactory. I greatly look forward to my porchfolk chiming in, thank you guys, have a great evening!
Another suggestion for the Kanger Sub-Tank mini - it can work well for lung hits as it's has adjustable air control.
Spent an hour or more hand coiling one of these clapton coils , which got me four inches.
Then I cut it in half and one half flew away and spent the next 45 mins or so trying to find it.
Wow - you've got some patience to do one of those coils. But honestly - after the work - does it really significantly improve your vape?
