Microcoils and other things

Microcoils
Has anyone tried making Microcoils inside their Penelope, Oddy, or Ithaka? There is a big thread on Microcoils and it caught my eye as I went through some 12 pages out of like 200+. It supposedly gives you the power of a sub ohm coil but it isn't sub ohm as it is usually around 1.5 ohms.

I have been enjoying making and using dual coils in my Penelope but I would like to do more experiments, and so I ordered some 30g A-1 Kanthal wire (which is recommended) to try this out and to see how it is. Some more information on it if you're interested, http://www.e-cigarette-forum.com/fo...271-micro-coils-increase-vapor-flavor-th.html

Is it possible to use no Non-Resistance wire and just use the resistance wire in the Penelope or Oddy?

I did some searching but there isn't a lot of information on it out there from what I can see. It would be nice to use just the resistance wire in order to remove the hassle of welding or twisting on the NR wire to the Resistance wire. Food for thought.

Reusing the same coil

Lastly, has anyone reused their build by just taking out the gunked up wick and sliding in a new wick? I've heard of some users doing this and says that it works. I'll try it out when my current build weakens.

Post #30 on this thread shows a micro (or close to it) in and Ody http://www.e-cigarette-forum.com/forum/gg/447365-vape-mail-3.html

You will need at least one N/R wire for these devices to work since the positive post is so far from the coil. Unless you can fabricate some other method of relocating a more permanent solution up to the ceramic channel.

I think re-using the coil would be more likely with cotton or hemp wick. Silica and ekowool collapse to some degree when winding so removing and re-inserting could be problematic. This might be easier to do with a micro coil, and I am not sure anything other than cotton or hemp will be able to wick fast enough. (Although IcyX is using Ekowool in his post)

I am running ekowool Mr Krinkle in my Ithaka, using ribbon wire for about a week now. Ekowool and ribbon down channels in my Penny for 4 days. And Ekowool and ribbon down channels in my Ody. As soon as these give out I plan on trying a micro in either the Penny or Ody using silica. I'm not sure the Ekowool will be able to wick fast enough to keep up with micros.

I might try using cotton for the microcoil builds I will be doing on my Penelope.

Decided to do some more searching today and came across an interesting post. This guy uses an Evod as an example, he basically twists the coil legs like a twine to increase the resistance of the legs so that it doesn't get hot, and the only thing that gets hot are the top coils. I will try this out on my next rebuild by folding a long piece of resistance wire in half, twist both ends and leave a inch or so of wire in the middle straight (not twisted). This would give me two legs, a dual coil in the middle, and no non-resistance wire used.

Doubling/Twisting reduces resistance so his "theory" is out the window..... ,)

This was first done on a Vivi Nova. The purpose is to minimize the burning of the rubber insulator. But I don't think in the case of GG atomizers since the distance between the coil and the positive post is long, you would need a lot more than 2 wires twisted to make the resistance minimal.

EDIT: If we twist them and trap them under the top upper nut inside the ceramic, wrapping it one time around post, maybe we give this a try?

Those of you who use cotton, do you guys just use rolled cotton or something like yarn?

I just use the bag of cotton I find in my local grocery store, I guess it's the same as you call rolled cotton. Yarn wouldn't work with a microcoil.


Try it ASAP.

Yup, I'm on it. I've actually got a huge roll of cotton at home that I used for wicks a while back experimenting.. never tried it with my Ithaka (or Ody/Penny) so I'm excited.. about to order some ribbon kanthal, too.. and now that I have a second Ithaka in the mail I will have all the time in the world to experiment! Woo, exciting!

im using cotton hemp, by the name of that lady, hmmm forgot her name lol, .... watch bishop's video cotton hemp

Perfect, thanks guys. I might get the ribbon kanthal on eBay, only so it ships faster... I found 100ft A1 0.4mm x 0.1mm ribbon for $27... definitely more expensive than vape-atomizer-mesh.com (depending on how much their shipping is)
I see cheaper ribbon kanthal on eBay, too, but it doesn't say A1, just says "Kanthal ribbon D wire" - unless there are any good US sources for ribbon?

Martha Stewart - so you say that works good with microcoils?
What ohm, are you using duals? How thick of a juice?

I ordered some ribbon kanthal as well... I typically aim for 0.6-7ohm dual coils, juice is about 80vg/20pg
Gonna try to find that cotton hemp yarn... do you just use one strand per coil or anything more?

Martha Stewart yeah, well i didn't say they work good with microcoils, actually Blix said they don't. And i dont know if they do. But the only problem with cotton hemp is that when you twist it is delicate, try using a pin, because it's like twisting around hair lol. I am using single currently but at 13 watts . regarding strands, it depends, i put them over each other until desired thickness, I don't count strands.

Cool - I think in Bishops video he uses one strad of yarn.. I'll have to watch that again, and as always.. EXPERIMENT!
I'm excited because I should be getting my second Ithaka in the mail today, so I have no problem trying new things, I don't have to be afraid that I will have to rebuild it right away if I don't like it!

Use an all R wire micro to figure out the length needed...take R wire at that length, attach your NR wire, and Krinkle it.

Done and done.

AND, use sterile cotton. Easy to feed through and replaceable in less than 10 seconds.

Been using this on one of my Ithakas.

This is what I'm going to do soon. Testing out a microcoil on other devices and so far it is going great but I'm not getting the warm vape that I get with the Penelope, probably because I'm testing the microcoils on BCCs. Vapor production and throat hit is immense using microcoils, most likely due to all the coils touching each other and they heat up very fast.

do microcoils have to be coiled outside the wick, and then the wick inserted?

I think that's how most people do it.. I've been reading that microcoil thread in the rebuildable forum.

Most people use 28g kanthal and wrap it around a 1/16" drill bit, wrap very tightly.. then when it's wrapped they torch it and then squeeze the ends together with pliers, this is supposed to help with the initial shorts that naturally happen with the touching coils.
Most people also have the best luck with cotton wick on microcoils, less so with silica I believe.

Another little trick some people do is put a "gap" in the center of the microcoil, so the center doesn't heat up quite as fast... gives better wicking (so I read). So it would look like this: |||| \ ||||

I ordered some 28g kanthal and when I get it I'm gonna try dual microcoils.

Subver how is your silica eko insert going?
