I can build a coil using 4 wraps of 28ga ss316L with a 3mm id and get 0.5ohms. By contrast I can also build a 3mm id coil using kanthal a1 and reach 0.5ohms using 12 wraps of 20ga wire. That 12 wraps of 20ga is going to take a shit-ton more power to get heating. In reverse for a mech mod where the power is fixed output, the 12 wraps of 20ga are going take a good while to heat up and provide a much cooler vape while the 4 wraps of 28ga ss316L are going to quickly blast red/white hot.
This goes a long way toward helping me get a better grasp too on how to build a coil around .20, that I can use on a mech without getting a blast furnace. It really is a matter of figuring out the different materials and how they each do, or do in combination.
I got surprised pleasantly when
@MrMeowgi was explaining about staged heating coils. I could build something that just might get me to .20 without being too hot. The trouble being though on a single cell battery it required a ton of power outlay to produce vapor, due to mass of the coil.
I wound up trying a .35 staged heating coil, that still required a bit of power but at that ohm rate it kind of equalized itself out. So, for about .35 I'd found a way to cool down a coil build but knew I'd need to keep abreast of how it was "drawing off" of the battery a bit more.
Starting to genuinely learn and earn an appreciation for detail orientation. My Pap would be sitting there looking over at me with his stiff lipped grin. Can almost hear him chuckling now as he reminds me how he was showing a difference between two different flies used for trout fishing.
There was more of a difference than I could tell to them, he knew that too. Reckon some of the lessons we learn as young boys come back as harder lessons to understand without those we love. It's alright though, I know he's still around.
And no, I don't mind "being schooled" here as long as it can be done respectfully & using constructive criticism. I'd rather stay an eternal student, or beginner than ever dare say I was a master and truly only be a fool grasping at straws in the dark.
