Hello everyone, ive been vaping for like 4 years but just got into coil building. I just got a subtank mini a couple months ago and have been messing around with the rba deck. Heres the problem I have horrible ADD and am horrible at math..but ive got the basic building parts down..for right now all I have to work with is 30g kanthal, and a coil jig. Now, i know how to wrap, and i know how to wick, but i just cant figure out or seem to get right how many wraps or the right diameter to make this damn coil.. its driving me crazy.. i keep getting it to read at around 1.4 - 1.7 and i really want around .5 can anyone please help???? (without yelling at me about math)
