Can't wait to get mine!

Good stuff Marc congrats it hits really well. Building the coils high up near the screws takes a little getting used to. What works for me is setting your bit or toothpick (whatever you use to wrap the coil) on top of the screws while you wrap the legs around the posts then tighten.
I have two twisted 28 ga coils @ .6 wrapped and waiting for this bad boy to hit the mailbox.
I envy those who can easily build a micro coil. I tried twice but failed as the coil was still springy even after heating it with a lighter.
So I decided to do one more and failed miserably again but I discovered the difference between wrapping the wire around silica wick straight and wrapping around a screwdriver first. The latter is giving me a much more consistent and satisfying vapour.

What gauge wire are you using? I'm sure we can get you sorted out!

30ga wire. I just read that you need to torch the wire before wrapping to release the 'springy-ness'. Dang, even the tip on my tweezer is covered with soot already :/
Oh. Interesting. 30ga shouldn't be too bad. Did you make sure that you torch/heat the wire till it glows red? I don't heat mine before coiling though.
Personally for me, when I'm wrapping around a tooth pick or a drill bit, I start by making sure that the wraps are as close as possible from the start. An important thing to note when coiling is to make sure you're exerting enough pull/tension as you are wrapping it.
A super easy way is to use an extra long piece of kanthal. Heat the length of it, making sure it glows red as you move down the wire.
Then wrap one end around your index finger to form a loop, and use your thumb to pinch the wire securely against your middle finger. This should give you a good "grip" on the wire so that you can wrap real tightly.
Your other hand should be pinching the other end of the wire against the drill bill. As you wrap, make sure you're pulling fairly tightly. Do it slowly and make sure you're wrapping as closely as possible.
In any case once your done, even if the coils don't touch nicely it's fine. Just pull out the drill bit, pinch the coil with a tweeze and heat. Since you're using a lighter, remember to try to use the blue part of the flame where it's the hottest and doesn't cause soot to deposit on the coil.
Hopefully some other people can chime in with other tips. For me, I think exerting extra tension makes it easy to wrap em close.

Yup, I got a good grip of the wire and pulled it as tightly as I can during the wrap. The wrap looks pretty close, but just not perfect.
I think my fault fall on the heating part with the lighter. I made the fire stay as long as possible at the coil but it just doesn't glow red, pretty frustrating too. End up with soot during the first try.
Perhaps I'll just let the lighter's fire at full flame and give it a try again. Thanks a lot for the input Mr Kiwi!
Oh! So 2 things
1) for the heating part to have any effects in terms of making it more rigid, you need the wire to glow red. Also getting soot on it probably isn't the best idea. I would recommend just getting on eBay and spending 15 bucks on a small little creme brûlée blow torch. Works like a charm
2) after wrapping, it doesn't really matter if it doesn't look pretty and tight. Just remove the drill bit, pinch and torch until the coil glows red. When you unpinch it, it'll stay nice and compact.
Seems like you're fine, and all you really need is a torch.
FYI, if your plier or tweezer is damn thick, it'll conduct heat away from your wire or coil, making it even harder to start glowing red. I personally use a skinnyazz tweezer.

Woohoo! Yeah, I just threw the coil away when the soot build up. Guess I'll get the torch soon and be back on the micros. My tweezies are ok I think, used the daiso screwdrivers set that came with a tweezer. Appreciate the help a lot for typing all that out man.
Cheers to you!
Microcoil without annealing.
1) cut a piece of rubber such that it fits in the groove of the spool. Tight fit to prevent wire from unspooling. This step is optional
2) unspool about 6 inches. Do not cut wire.
3) wrap end of wire around handle of screwdriver. 2 wraps should be sufficient. Tape it down with masking tape. Scotch tape does NOT work as well.
4) keeping a constant tension on wire, (by pulling screwdriver towards you), turn the screwdriver. The coils will be nice and tight as you turn the screwdriver. Don't worry about the first few and last few turns. They are usually unwrapped as they are just the starter coils. That means your coil will have a couple more wraps than what you're aiming for.
5) cut off wire when finished and unwrap by pulling on legs.
Hope this makes sense to you.
But be aware that on regulated mods, the coil MAY fire at first and then read low ohms. That's because the carbon hasn't built up yet.
I personally only used this method for a few times only. Prefer to do it the usual way.
Clarification of step 4:
You're supposed to pull the screwdriver towards yourself to maintain tension, but to get the coils coiling, you have to turn/roll the screwdriver AWAY from yourself.

Thanks to my vast imaginative powers, it makes sense to me. Pretty interesting but clever way of wrapping the wire I'd say.
I usually fire the coil several times after the first reading and at the same time burning off the funky silica smell. Then I take a few more readings to confirm it's all good.
And of course, thank you for the alternative wrapping method
Yes 28 Awg makes a easy coil for most types and produces quite a fair amount of vapor

Bro... sometime lighter may not be strong enough. Like i alway teach my frens, use your kitchen stove la (bcos when u do build, you will be at home right?).. lol.. i cfm plus chop the wire will glow red in less than 30 sec while BBQ on the stove
Make sure you have good tension while doing the wraps. And dun worry that the wires opens up aft coiling. No 100% one. Just screw it onto your tank like you would. Heat it till it glow and use your tweezer to press it tight. (warning dun press the wire when it is glowing, you will break the coil). A bit open nvm one la.. Important thing is its work.. Boleh liao..
I counted around 14 - 15 loops might be using 28 or 26 awg
