Last night ECF was wonky for us so I took some time to knock one off my vaping bucket list.
Started w/ 10 wraps of 28g kanthal around a 1.5mm rod. And made two of them. I put the formed coil in helping hands jig, torch it glowing, then squeeze together and repeat a couple times.
1st one in place. The leads are wrapped totally around the screws to hold it in place. Left it on the rod while positioning and looping the leads around the screws.
Just enough (I mean just enough) to fit 2 coils w/o them touching each other or the terminal screws. Took a bit of fiddling, using the the rod inside the coil to coax them into position.
Tested it w/ a DVM and it came out to .6Ωs - opps! I was shooting for .8-.9Ω. Oh well, make that 2 check-offs for the vaping bucket list (dual coils & true low sub-Ω). Looked it over real good for short and then lit it up.
Filled it w/ some cotton roll, juiced it up and gave it a test run.
conclusion: this is a build I won't be doing again. It's much more fiddling than a single coil that for sure. But my goodness, for my taste, it's so warm bordering on hot. It certainly packs a kick but much too warm for me.

Finally got my airflow things for my Protank and I can now use my P-whatzit! Oh I am a happy camper
I have good luck with my single mini coil on my KFL's so think I'm going to stick with that.
