I've described this before...
OK. When I got my RM2 and some 29ga kanthal, I found a random screw on my desk that's half threaded, half smooth and was probably the shaft for a little pulley or other mechanical
device at some point. I have no idea what the diameter is but it probably isn't so much different than a #10 or something. - I nipped a few inches of wire off the kanthal spool and eyeballed how much to torch with my lighter guessing from a chart I saw one time describing ohms per inch. I wrapped that around the smooth portion of the screw a few times and then twist the screw to remove it- makes a nice looking coil. This 510 ohm-checker-thing-a-ma-bob I bought for a few bucks that probably doesn't know what it's talking about with any degree of accuracy says those
coils all come out about 1.25 ohms after having their legs stuck in the holes of the RM2 posts and nipped off behind the screws. Then, I cut a little japanese cotton off a pad with my pocket knife and stuff that through the coil... and then I cut the ragged ends of that off with my pocket knife as close to the edges of the deck as I can so installing the cap won't drag my wick around too much.
It comes out looking like this and it cranks out all sorts of flavorful vapor.
OK... So, I really am that uninvolved in "building". I really do use just some random screw I found - I really do use my pocket knife on my wicks - I really don't trust the ohm-checker-thng-a-ma-bob and honestly only use it to quickly check I don't have a short.... but I will admit I do own a decent multimeter... which is why I know I can't trust the ohm checker thing a ma bob. I just don't much care if my coils are exactly this or that so long as they give me good, flavorful, thick vapor when I push the button and take a drag. The set up in the photo produces exactly what I want - good, thick, flavorful vapor... and I can reproduce that exactly every single time. -- I made a few mistakes at first, but now I know exactly where to place my coil and I know what too much or too little cotton feels like in my fingers.
