It's very hit and miss for me right now. I think one time I got a decent vape out of it and thought i'd cracked it but now its more or less every time i'm having a problem.
Using 0.25 wire, tried 4 wraps, then 5 and six. I'm not getting much taste or vapour, its actually quite a weak taste of the actual juice i'm getting and it somehow seems tainted, no matter what flavour I try its the same tainted taste and i'm convinced (and probably wrong) that its the cotton wool i'm using, which is 100% natural. I've boiled and dried the cotton wool. (basically threw a few balls of cotton wool into a pan of boiling water for a few minutes, drained and dried slowly in the oven.
I'm just pressing the coils together and not heating them etc and the screw i'm using is 2mm in diameter.
Anyone have any ideas?
