This shit is fucking frustrating. I spent all night hand twisting wires because I have no drill. I've hand twisted 2 strand wires a few times, so I decided to step up the game. I made 2 coils of 5 wrapped hand twisted 4 strand 24 gauge kanthol, and the are gorgeous in my opinion (pics below). I mounted them in the velocity deck of my iJoy RDTA Box mod (the post screws are kind of janked up from working them so hard, I really need new ones), everything is tight and secured, but when I go to test fore it, it either says "Shorted" even though there's no wire touching metal anywhere outside the postholes, or one coil heats up red within 3 seconds and the other stays fully dead. Please help, I really want to try these coils I made~

I did some quick calculations and found your issue. I guessed at your inner diameter for these coils(3mm) and the resistance for your build comes to roughly .063. that's wayyyyy too low for a kanthal build, most mods only go down to .1 in kanthal mode. That's why your mod doesn't seem to like your coils. You would need to use 28g for that build to be functional.

Inner diameter is 4.5 mm, it ohm's at .1, and RDTA Box can ohm as low as .05, plus I have LG HB6 High Drain Pinkies in it.

.05 minimum is for temp control only. it's a .1 minimum for power mode. the mod could be reading it at .09 hence not firing.
any reason you want to go so low? i mean a .2 build will work just as good. and you really don't need the HB6 unless your vaping over 150 watts

Ooooh ok~ The pinkies just in case my calculations are incorrect in some area, but woth a build so low with so much wire, the ramp up time is super slow, so running it at about 175 watts would be ideal anyway. But that doesn't explain why there are periods when only one coil will fire?

Try putting just one of them in and see if it will fire it. If it fires one but not both, then it's definitely the ohms. Both Coils might not be close enough in resistance also, and it could be why one of them is firing faster than the other.

When both of them are in it only fires one. It isn't that one heats up faster than the other, it's that only one of them fires at all :/

Sounds like you are running too close to the edge to me too. I agree with Mista Malice here. There are only a few likely candidates here and you have to start somewhere. Might AS well take the advise of someone that has been here a few times and start troubleshooting. One coil at a time.

If one coil is heating up completely, your shorting at the dead coil, see if your ohms jump when strumming the dead coil without firing, you may have a screw not completing the circuit causing a "short"error, if you wiggle test the dead coil and theres alot of play in that dead coil, thats where your short is, in regards to that build, it is really low and "technically" unsafe to vape that low with any kind of 18650 battery, build with higher gauge wire, 28g with 4 wire strands

20170430_115424-1.jpg More wraps. Im running a 26awg twisted twisted with another 26awg twisted. And Duals reach a .2 ohm oh and there's a 36 gauge n80 wrapped around them (far spacing just too) but more wraps higher resistance and more wire to evap juice (IDK those might be 28awg)

A pic of the coils installed would be helpful, but I would remake the build with an extra wrap and see what happens

I just said fuck it and dropped $35 on a Laisimo 200w to up the watts lmao
