    Default Ohm - stuck at 1.5

    Just a quick one here. I've been recently playing with mech mods and am trying to get into practive wrapping low res coils. I'm using 400 SS mesh for wick and 28ga Kanthal A-1 for my coil wrapping 2/3 and all my coils come out at 1.5 ohm. I'm trying to get to the 0.8 or 1.0 ohm level with no success. Anyone know what I might be doing wrong? Am I not wrapping my coils tight enough and therefore using too much wire? Help....

    How are you measuring your resistance? The resistance is due to the amount of wire you use. With 28g and that few wraps, you should be hitting the sub 1ohm with no problem. Is your wick really really fat? If you're using a multimeter, remember that you have to touch the 2 leads together first to get a base reading, then subtract that reading from the reading you get when you touch the leads to the atty. My multimeter has a base of .3 so if I get a reading of say.. 1.5, I know to subtract .3 and it's really 1.2

    That doesn't sound like 28g at all. If I wrap a 1/8" ceramic wick with 30g, a 4/5 wrap comes out at around 1.5 ohms every time. There is no give in ceramic. Maybe you have a mislabeled batch of wire. A 2/3 wrap of 28g should definitely be a sub 1 ohm coil.

    im not saying that this is the problem but one time I ordered some 28g wire from OKC vapes, when I opened the package I knew right away that they had miss labeled it. the wire was actually 32g instead of 28g. I believe this was an isolated incident, and have ordered from them since, they have great prices on wire & mesh. im sure you also would of noticed the difference in wire gauge so most likely it is something else, but it is a possibility.

    Ok this is off topic but pls entertain me. Does more coils mean less resistance?

    more coils is more resistance but it is the length of wire & the gauge that determines it. 28g is thicker thus it has a lower resistance of 32g. think of it as a hose, the larger the hose the more easily water is traveling thru it, so there is less resistance on the water. now a thinner wire is higher resistance, there again a hose, water traveling in such a small area has more resistance on it, like it is being forced thru it. now the hose is the wire and the water is the electrons. besides this it is also determined by the length of the wire, the longer the section, the higher the resistance.

    Thanks, would you have a clue as to how I can achieve a approximate 1 ohm coil on 32g kanthal? And if it is safe to run 1ohm on a 3.7v aw imr 18350 battery?

    this is why I always preferred low resistances, I feel like the extra volts needed to force the electrons thru such a small wire has an affect on the taste of the vapor. a thick wire is like a race car, where things are cruzing thru uninhibited, fast ,and more freely, where as a thin wire is like a traffic jam. once you use more then 4.5 volts, I believe that this becomes much more harsh, and more metallic in flavor. I much prefer lower volts, which is lower resistance.

    it is really dependant of the diameter of your wick, on average maybe a 3/4 wrap? I haven't used 32g wire in like a year, the closest I have is 30g with a 3/32 wick, this set up is a 4/5 wrap coming in at 1.1Ω. so if you have a smaller diameter wick then I would guess around 3 wraps, but TBH it has been a while. you can try 32g for low resistance but it is not the way to go. the smaller wire imparts more heat to the wick because it is heating a smaller area, a thicker wire spreads out this heat more, so you will get a much smoother vape and a lot more flavor from a thicker wire. for low res set-up use 28g or 30g. 32g is really made for higher res. and yes to your last question. aw imr bats are the best

    Ok thank you sir. I'm using a aga (1.4ohm) on a vamo now it's ok I guess but I wanna try a 1ohm. Currently waiting for Hoosier to stock up on the k-100 (empire clone) for my 1st mech mod.
