Ribbon wire coil building

[Chnoubis]

What are you wrapping your coils on? A drill bit?

no I use one of the small screwdrivers. You could say its probably more around 1/8 inch in diameter than 1/4 I tried using the ones to measure with the cotton in it hard to tell so I just made a new wrap on the screwdriver to see.

Trying to find the specs of my mod online no luck so far.

It's a dual 18650 mech box, wired in parallel.

Alrighty, I'm under the impression your multimeter is off, or it's not being read correctly.
I'm assuming it has leads. If so, are you touching the leads together to find out the meter's natural resistance and subtracting that from your atty's readings?

This has me slightly worried.
I have a dual coil 22g build in one of my drippers right now, and it's .3 ohm, 10 wrap around a 3mm bit.

1/4 inch is a hair above 6mm, to get 1 ohm with 22g you need 19 or 20 wraps.

I think you're vaping much lower than you think you are.

I'm going to check it again.

I build everything with ribbon. I bet the legs are too long. I use silica for wicking. Never liked cotton.

If it's 1/8 inch I.D., with 9 wraps of 22g in dual coils, you'd be hovering just under .3 ohms.

Sold, my next project will be ribbon wire.

Ok so I have 4 posts my multimeter reads when checking it by itself is reading .2 so of course subtract that. Ok so the dumbass that just helped me read it was wrong I just did it myself and I'm getting .4 per side which would mean .8 subtract the .2 so i guess its a .6 ohms

Ribbon wire is awesome in a dripper 3x the surface area of round wire touching the wick surface = more vapor. Easier then a round wire micro as well just wrap close together and done no pinching, heating poking etc.

Look at it this way the microcoils work so well becuase you have many wraps making a long coil. Creating a lot of surface area (and this really is all they are doing)
With ribbon 1/2 the same amount of wraps will give you a coil just as wide

I use ribbon in my dripper and even at .8 ohms it looks like a fire extinguisher the plume is so thick lol

Bit harder to work with at first but worth it, all the benefit of some micro without having to go to .000006 ohms lol

nice definately going to try ribbon next.

Ok I'm a little confused now 4 posts is ....ing with me I should be reading from the first post to the last post to read both sides together correct because if I do that your reading is correct it jumps between .3 and .2 ohms

Aha!
So we can blame someone else. My favorite.

Now, when you say 'per side', how are you measuring?
Are you sticking one lead on a negative post, and one on a positive and firing? It should be able to read both coils' resistance at once, so I'm thinking you may be closer to .2 ohm.

You are correct my friend I read from one negative post to the other negative post to read all together and it is jumping from .2 to .3 which your right on the money! Yeah and we can blame somebody in the navy who works with a multimeter everyday which I do not I load bombs for a living he fixes wiring and electronics.

Thank god he's not working with bombs...

My buddy has .9 x .1mm ribbon wire to small or good size?

If this is your mod, your batteries are wired in parallel. Cigreen Tank Crossing Box Mod Review

Forgot to mention, make sure you "marry" your batteries. Here's a thread on this subject: Dual 18650 series/parallel battery marriage question

lmfao tell me about it. Ok so now knowing my actual ohms I'm running thanks to you is these trustfires safe to go any lower if I remake a coil build or should I wait for the other batteries to arrive?

awesome read on the marrying part glad I'm already pretty much doing that just didnt label them.... they charge together and stay at the same power all the time.

I'm not quite sure about the Trustfires. I really have no experience with them. Can you tell us a bit more about them? Any writing on the wrap? It'd be nice to know what the mah and amp rating is.

Personally, I wouldn't go any lower then where you're at now, even with the MXJO's. You might want to experiment with twisted or parallel builds. Both of them give (subjectively) more flavor and vapor due to the increased surface area. I prefer twisted over parallel, but plenty of folks swear by parallel coils.

Trustfire: IMR 18650 1500mAh 3.7V (right off the wrapping)
I'm going to need bigger gauge wire like move to a 26 if I'm going to twist because I really dont have alot of surface area in this addy or buy a bigger addy.

After googling those, I don't really think I'd recommend them for much long-term use.
Just about everything I read was about how inferior they were to other batteries. Ie: Samsung 25r, LG HE2, Sony VCT3/4/5.
More than once I saw "I wouldn't trust something with Fire in the name."
I would hold out until you get your new batteries to do any new coils.

Aah, when you say bigger gauge, I automatically think thicker, not bigger number.
26 isn't bad. I have twisted 24g in one of Mutations currently. It fits pretty well, but you have to center the coils between the center posts.
You can always use thinner wire, and twist more than two strands together, too. Lots of customizability to be had.
