I built dual coil at .4ohm..

I just looked down at my vape and now it's reading .2ohm

Yes I'm the same idiot that just accidentally lit my cotton on fire.

Okay so, Just took the top cap off... While hitting the switch I'm only getting vapor off 1 coil, Did I pop the other one? Is it still safe to vape with a popped coil?

If one of the coils was popped, you would have got a reading up from 0.4 ohm to 0.8 ohms.

Since your ohms dropped most likely one of the coils was touching and shorting out on the deck.

That's odd. A dual build at .4 means each individual coil is at .8, so if you popped one of them then the ohm-reading should be doubled, not halved.

Except for hex screws... They never back out.

How do you figure? I'm racking my brain to figure out how the shape of the slot in the screw head could affect how the post behaves after it's been tightened...

have had my build in my derringer for weeks now and never have had to tighten down the screws. In my Haze clone I had to every other day.

Your derringer uses hex headless screws.
Your haze uses phillip headed screws.

Your symptom is due to headless versus head, but you assumed your symptom is due to hex versus phillip.

The headless screws can continue to screw down; the headed screw has to stop when the head hits the top of the post.

Oh that's odd, So the coil that wasn't firing I most likely shorted out... What exactly causes that? Coil touching the post? There was no way it was touching the other coil unless it was touching in the center post lol..

my guess is it was touching the deck below it. The deck is negative. The center post is positive.
