    Hi guys,

    Just got into making my own coil and was wondering if you guys could comment.

    I was planning wrap my coils around the tip of the juice dripper. My coil is a kanthal a1 wire 32AWG.

    I want to achieve 1.5-2ohm. To reach 1.5ohm how many wraps do I need? I am using a Vamo V5 and Protank 2/2 mini.

    Any advice will help thanks :)

    With a 1 mm inner diameter and a target ohm of 1.8 that would require 7/6 wraps according to my "vaper's toolbox" app.

    So that's me assuming the needle is 1 mm in diameter.

    What are you planning to use for wick? Are you planning to thread wick through or surround the coil with a "cloud" like a dragon coil build?

    I don't know about 32g but 9/10 wraps of 28g will get you right at 1.2ohms.

    I use a needle tip also, but with 30 gauge. 12 wraps gets me to 1.95 ohms. I either use rolled cotton, or - more recently - 2 strands of Peaches and Cream threaded through the coil, which gives a very nice vape!

    Using cotton as wick :) Am not sure how the "cloud" looks like, any pics? May try it out :D

    Basically 28g is thinner than 32g am I right? So I read somewhere that using a cocktail tooth pick will give me about 2ohms if I wrap 5-6 so if I wrap less around 3-4 I may just get between 1.5-1.8ohms. Possibly?

    No matter how many wraps or what gauge wire you use make sure you test the resistance BEFORE you fire it on your battery:)

    As the numbers go down the wire is larger.

    Lower gauge increases the size, like wire or needles, zero gauge is about the size of a pencil, 24 gauge is the "normal" standard for ear rings, a nail is 8 gauge I think, make a little sense?

    It's best to just get an atomizer ohm meter and know for sure, guessing can be dangerous. Once you get micro's down, it becomes second nature to know how many wraps it takes to get the desired ohm's build. They are just that consistent of a build.

    "Second nature" can get you in trouble :)
    As Dice rec, get an ohm's meter or a multimeter to be safe :)

    Will definitely try to get an ohm meter.

    The coil will have to be set into the protank before I can measure the ohm am I right?

    6 or 7 wraps of 32g around that tip should put you in the range you're looking for. Get a multimeter and/or an ohms checker thing. I use sterile cotton for all my wicks.

    Just screw the coil in the base and attach the base to the reader. The good thing about rebuilding your own coils is that kanthal is cheap and if you aren't happy with the build, or are shorting out, you can rebuild it again

    No, you NEED an ohms checker. Don't build without one, unless you want to short your batteries and ruin your stuff. Don't just "try" to get one.

    And if you do like the build....you can remove the wick after a while, dry burn the gunk off the coil, and rewick it again

    Yes, that is correct. I am not that familiar with protank but I do know it needs to be in place with rubber thing that holds the legs of the wire.

    Sweet cheers guys. Will definitely give this a go. And will definitely get the ohm meter cramptholomew :D

    Btw so far using 100% cotton gives me good results with having another cotton on top of the wick (as a flavour wick) and flipping the grommet around also stops gurgling etc.

    Get an Ohm meter and measure what length of the wire gives you 2 ohm; that is the LENGTH to use; it is not the number of wraps that matter, it is the LENGTH.

    Remember to check the meter for zero offset

    I know nothing about building E-Cig coils, but I do know about resistance wire.

    It'll have a very linear resistance per foot measurement.. You can check it with a multimeter (Or if it's spec'ed, just look at that) and divide from there to get the length you need.

    If you're wrapping a coil, a small, coarse thread screw might help.. Maybe wrap it around that?

    No, you are wrong. 28 guage is thicker. the thicker the wire the less resistance the lower the ohm, depending on the wrap. 32 guage is a nice guage to learn to wick coils. Since you got that you should be in good shape. harbor freight ohm meter get one they are only 5 bucks
