I got into rebuilding late last year when I bought a Squape R. I've built numerous coils in the 1.2 to 1.8 ohm range with Kanthal. I've always run the Squape on my regulated mods in the 15-18 watt range, using 24 and 18 mg/ml liquid.
So I recently got a new mech mod and wanted to build the Squape to run in the 12-20 watt range, over the life of my battery, so I got a simlar vape to my regulated devices. Now I know mechs are supposed to have some voltage drop under load, so I figured a 0.8 ohm build would probably work. My builds always seem to come out higher than steam engine says, so I went with a five wrap of 28g Kanthal A1 on a 2mm jig. I heated and squeezed it and it was reading 1.07 ohms. So I pulled it out, increased my lead length from 5 to 10, cause 5 seemed a bit short, on steam engine, then it showed I'd get a 0.77 ohm with 4 wraps. So I did a four wrap and it metered around 0.95 ohms. It was a nice spaced coil so I didn't squeeze it. I figured it was low enough for now, so I pulled some cotton through it, wet it, and put it on my VS to test it. On the VS it was now reading 0.73 ohms, but it worked fine.
So finally put it on my mech mod and vaped it a few times, talk about a nicotine rush. Anyway, the taste isn't bad but the nicotine seems like a killer with 18 mg/ml juice.
So where did I go wrong? Why did the coil resistance change so much when I wicked and wet the coil? What ohm build do I need for that 14-18 watt vape? I think I way over estimated voltage drop.
Rebuilding is still pretty new to me, so still a lot to learn I guess. Thanks in advance for any help.
