This has recently become popular and will save you a lot of grief. Takes all the work out of it, it's really cheating. We've all had to do it ourselves, now a days it's all calculated for you..


Coil calculator.
Coil wrapping | Steam Engine | free vaping calculators

Very cool thank you for that, I knew I had seen it before in someones sig here but couldnt remember the members name or the calculator app name. I keep hearing about this "vaper's toolbox" but everytime I look on iphone app search I dont see it.

My question is if you don't know how to do it what makes you assume you need it?

Got a hex ohm which calls for minimum of 0.6 ohm atty for chip longevity. Not used to wrapping sub ohm coils that high.

9 wraps each around a 5/64 bit with 26g.

5/64 is a bit thin for my liking but if that hits it on the dot I might adapt. Thanks!!!



I've been playing around with this steam thingy here just punching in my reg builds I vape and it's actually been pretty accurate. The only one thats been a little crazy is the recommendation above, it said 12 wraps on 5/64. Anyways thanks everyone

Coils can fluctuate up to +/- .2 ohms. So shoot for .7- .8 so it fires all the time.

I did a 1/8th bit 8 wrap 26guage kanthal. Put it on the meter...0.6 ohm on the dot. It's a center post build on a 3 post atty so the legs are a bit longer than a normal offset build would have. I'll take it though, thanks for all your help and suggestions, and I'm loving playing around with this steam software, lot of cool features to make life a bit more convenient.

heres how to find it all with math:

((((dia. of wire + dia. of winding shaft)*3.1415)*# of coils)+.5) * ohms per inch of wire

so if you have 28ga
wire dia = .0126
resistance = .439 ohms per inch
winding shaft = 1/8" or .125
X # of coils needed will be 1.4 wraps for a single coil
or 5 wraps each for dual coil but you will need to keep the legs very short

What is the +0.5 for? the legs of your coil? And isn't the cut length going to equal 1/2 the diameter of the wire in that equation?

i ask because i like to know why and how and i prefer to check anything i use an 'app' for myself.

T

yup the .5 = 2 legs at .25" each (just an average from experience)
you use 1 whole wire dia + shaft diameter, if you take the center of the wire as the origin of wire you have 2 half widths on each side thus making it 1 whole width...
