    I just wrap what ever looks good I think I'm wrapping micro coils (im probably not) I use a 2 mm rivet somewhere between 8 and 12 wraps all touching or as close as possible usually I come out between 1.5 and 2 ohms using 30 g kanthal but there's absolutely not method to my madness I'm all about trial and error and a multi meter

    Hmmm, well that worked. I just did a coil using 32g Kanthal, 4 wraps around a 2mm drill bit and it came out at 1.7....about where I was aiming. I thought I was using 2mm drill in my previous attempts but discovered it was 2.5mm.....I assume that makes a difference. Anyway I'm happy with 1.7.....using it on an eGo Spinner so I don't want to get much lower than that from what I have read.

    Thicker drill bit = more wire required for one turn or wrap = higher resistance.

    2mm drill bit = 3.14mm of wire needed per wrap
    2.5mm drill bit = 4.90mm of wire needed per wrap

    as a plumber I always compare anything to with wires/power to water pipes.
    If you make your pipe longer it builds up more resistance to the water flowing. Get a really long garden hose and a really short garden hose and attach it to the same tap, your allways get more water out of the shorter hose. Same if you make the pipe smaller.

    Thats how my physics teacher described basic electrical theory. Made it easier for teenagers with no real world experience to understand.
