You need a multimeter to check the heads connected fine and that you aren't hitting the ohms limit (around 1.4 on the itaste?)

Mr. Chrome · 27-08-2013 12:41am

What size wire and wick are you using?

DublinCJM · 27-08-2013 12:45am

2mm wick and I think the wire is 0.20 kanthal 032 or something like that

Did I get the wrong stuff

Mr. Chrome · 27-08-2013 12:51am

4 or 5 wraps of .20 should be, I dunno... 1.6 to 2 ohms I guess? Could the wraps be touching each other?

DublinCJM · 27-08-2013 12:55am

Don't seem to be but if they were (maybe underneath the wick) would it still fire fine on the ego?

And is it ok to use or will I feck my battery up?

Thanks for the help/advice by the way.

I'll try another few tomorrow!

Mr. Chrome · 27-08-2013 12:59am

I use 1.2 ohms on egos all the time but its not recommended :-) I've used coils as low as .8ohms on egos just for the craic and it worked! If the ego gets very warm, stop using it.

DublinCJM · 27-08-2013 1:02am

Ok thanks!

1.4?!:eek: crap...

Finally got a genesis type atomiser to work, about 6 months after I first tried:o

My RSST is now properly working with 500 mesh and 0.25 kanthal wire. Tried already with SS rope and ribbon kanthal with no success. Feels good to finally get it working! Have to say the flavour and vapour are good, looking forward to having a non silica device that I don't have to rebuild on a regular basis, it will get a lot of use I hope.

Just followed what Todd did in his review and after a bit of adjusting the coil glowed evenly. I'd gotten this far previously with the AGA but when I put juice in the hot spots returned. Finally:D

Igo-w build...

3.4 ohms, built a 1.1 dual coil just before but SVD wouldn't fire

so went for more wraps on a single

Igo-L cotton set up

This was my first attempt at a cotton wick and turned out good, couldn't believe the juice retention of the cotton

What type of cotton Ghogie? Looks right at home in there!

EGriff · 05-11-2013 9:28pm

Cotton really does hold a lot of drops, I'm even using a dripper while driving now since the cotton wick I have in there can hold about an on and off hours worth of juice.

Green Hornet · 05-11-2013 9:44pm

There's a bit of a trick to cotton though. Too much and it'll slow the heating of the coil down/flood it a bit even on a dripper.

Looks tasty. Did you wrap the coil around the cotton or feed the cotton through.

dball · 06-11-2013 11:38am

Can someone point me to a recent post explaining the length of wire = xxOhms - I cant find it and i'm going to have a bash at this today

was.deevey · 06-11-2013 12:09pm

Use a multimeter if you want to be accurate.

Hold the probes along the length of the wire at various distances before your wrap and you'll see the Ohms reading changing, just clip the wire where the probes hit the desired length or mark it with a sharpie of something if you prefer having a long cable to wrap with and clip it afterwards to the right point. Job done.

*you may need to leave a few mm extra depending how your terminals connect.

grindle · 06-11-2013 12:12pm

If you have an android phone get Vaper's Toolbox. Has all the wire info ready to calculate.
Otherwise, tell us what wire you have.

1 meter wick (2mm)
2 meter heating wire (Kanthal 0.2)

No multimeter - just a starter pack and a little bit of hope:eek::eek::eek:

Yeah very juicy haha still trying to make myself remember 'not silica, not silica' haha

I just got organic cotton balls and boiled them in purified water and let dry, they kind of dry back into a cotton ball then

Yep I wrapped the coil and stuck it on the posts, checked everything was firing ok then got some cotton, rolled it tighter at one end and fed it through, there was enough 'fluffy' cotton to go around the little well and the excess of the tighter rolled side, I tucked under the coil

0.43ohm/cm if it's Kanthal D.

So 4cm length = ~1.6ohms, 5cm = ~2ohms, 6cm = 2.4ohms, etc etc.

Cut with an extra 5mm either side for legs to put into or wrap around the posts (probably need an extra cm or 2 if you're rebuilding clearos).

Always find out your resistance per cm and get the right length and you'll be grand. People talking about wraps is misleading because every wrap is subjective to the wick, tightness of the wrap, closeness of the coils, softness of the hands, sensitivity to touch, fingers running around the girth of your red-hot, spitting...coil.
A certain length of a certain wire cut a hundred times is the same resistance every time.

I see your point but if you're using a micro/nano cool?

I've changed resistances substantially just using a tweezers and a blowtorch...

I haven't seen any change, resistance has stayed the same whether nano, micro or normal. How long are you torching for?

I'm pretty sure I've gotten the resistance to increase by heating and getting all the coils to touch, this also stops the legs of the coil heating up. Not torching for very long, maybe 10-20 seconds, just long enough so that when I squeeze the coil after heating it stays together. Resistance increased from 1.3-1.4 to 1.6-1.7. You'd imagine the resistance would decrease when everything's touching... I dunno.

Also saw someone mention it in a video, can't remember who.

Mr. Chrome · 08-11-2013 8:03pm

I presumed(probably incorrectly) that with a micro/nano coil the length of wire didnt really have much to do with the resistance.
I thought because the coils were touching it made it like one big wrap, kinda like one huge wrap of ribbon kanthal?

Could it be possible that heating the coils, and causing them to oxidise would mean that the diameter of the wire is reduced thereby increasing the resistance. Seems a lot though.....but still a theory!

grindle · 10-11-2013 12:46am

I had a much longer post on a separate device, but basically - if a microcoil became one large mass of metal just through touching then microcoils would measure 0.3ohms or below (based on the shortest path of resistance theory) vs the 1.5-2ohm they usually occupy.
Electricity follows the path of easiest resistance like a river, not the first point it comes across like some people think (like a certain hifalutin redditor I read recently).
If microcoils started at almost-zero ohms VV devices wouldn't fire them. We know that's not true, so we know the people who think that are full of shìt. End of that redditor's discussion.

Depending on the material further annealing causes an increase in resistance.

That shortened my previous post by about ten lines, thank fûck.

Mr. Chrome · 10-11-2013 1:22am

Yeah, I get what you're saying about the path of least resistance, its just that when I started rebuilding, the mantra was 'dont touch coils together, they will short out'. Now its 'touch away, tis grand'.
Reminds me of how people used to oxidise mesh, burn-quench, burn-quench, etc. etc.
