Questions/plz advise
when caring for a coil (mostly rba pre fab coils) and wanting to give it a nice long life what are some things you don't want to do to them? What destroys these coils? I have very little experience when it comes to the rba or coil maintenance and I am wanting to keep the few I have going until my order comes. plus it would be nice to know this stuff for the future so I can get the most out of each one. and in the meantime I am trying to learn how to make my own coils, I'm just not great at it... I suck at it actually...

[IMO] There's no such thing as a long life to coils. Things to factor are how often you're using it & the type of juice you're using (some gunk up the coils faster than others). If you're using a RBA you can switch out coils as often as you like. If you're using coil heads you can always wash them out really really good & allow them to dry. I give mine a 190-proof Everclear bath.

A microcoil is not just the appearance, whether they're symmetrical or even touch…it's about what it does, the function. Super_X_drifter conceived the contact micro coil as close and intermittent contact winds short, i.e. go hot. Merely forming a wire into symmetrical shape does not give you the oxidation and performance advantage that a microcoil is intended to deliver.

Two ways to make one. The first is to torch it and compress it as seen in so many videos. But what completes the coil and insulates it from going hot is ultimately pulsing it electrically. This finishes the surface oxidation. Unfortunately torching it carbonizes the surface inhibiting alumina oxidation. It's uniform oxidation electrically that makes microcoils wail. I adapted a method long used in industry to make vaporizing coils using tension by hand winding in under 30 seconds. No need for torching and it's as uniform as nature can make it. It'll get ya where you need to go vj (and cheaper in the long run).

Good luck.

THANK YOU SOOOO MUCH! I plan to give it a good go this weekend. I ordered cotton and rayon yesterday to see what I come up with.
Do you have tips as what NOT to do to these pre made coils that came with the rba cotton for the egrip? Like not firing them while they are wet? Or anything that might ruin the wire itself? I was going good with those coils until I went to clean em up and rewick them. Now, it seems no matter what I do I get burnt hits. It tastes burnt when its totally saturated too... I'm at a loss. So I wonder if I'm not maintaininf the coil itself correctly?
And, where do I get a tool to help me wind with tension?

Sounds like you're under wicked. Try using slightly more cotton and lightly rolling it between your fingers to help get it through the coil.

As great as y'all say booze works, I'm a recovering alcoholic (4 years clean and sober in March and having that in my house is just asking for trouble... soooo, what's the nezt best thing? Right now I'm concerned about rba coils, the pre made ones from joyetech for the egrip. I feel like as soon as I dry burn them, rinse them, fire it again before wicking it they are no longer good because no matter how much or how little I wick it, it is burning. The coils were only used a week tops. With clear juice. Either 50/50 ratio or half 50/50 and half vg, since I'm having to dilute my 18mg juice to avoid getting nauseous... Either I ruin the coil while trying to clean it up or I'm not cleaning it well enough. I'm so frustrated. Today my egrips stayed home I.miss using it, so much... Soon I'll have new coils, new wick material (kdg cotton and rayon) and distilled water... I want to go into this with all the info my brain can handle. This is one rba I refuse to loose with... my egrip will not go into my vaping graveyard... and stock coils just suck... and burn... I APPRECIATE ALL THE HELP

Under wicking will burn the juice?

 

[Riff89]

More like burns the wick because its thin and juice vaporizes quickly and then coil burns the cotton and gives you burned taste.

I've had my egrips over two months, and two of them still have the original RBA coils. I change the wick as necessary, just dry burning the coils in between, and they're still going strong. Your problem must be from incorrect wicking - not enough wick to make contact, and you'll get burning. Too much wick and the juice can't wick properly! You shouldn't have to change the coils themselves that often.

4 yrs C & S..........CONGRATS to you.
I don't drink so this bottle will last quite a while since it's only purpose for me is cleaning coils.


As mentioned, you're probably not using enough cotton.

I NEVER woulda figured that I was under wicking... Oooo, I hope this is it!!! Thank you!!!

Well... that makes sense... I am excited now... can't wait to see if this helps!!!

Thank you
This under wicking info seems most likely... I live this forum... thank you ALL... I will report back, hopefully tonight.

Why size kenthal wire would people suggest for the rba? Also are there any jigs which wind with tension? I currently have a kuro koiler.

 

[vjdossey]

Cigatron: I would like a tension winding jig... if there is such a thing. I think you've mentiones it somewhere... I think my fiance could be able to make one, if I knew what to tell him I need. However buying one might be a better choice! Any suggestions? Please

Two threads where super_X_drifter, cigatron, many others and myself add copy on the simple methods for using strain to perfect tensioned winds and the mechanics of installation in anything…

Tensioned Micro Coils. The next step.

Protank MicroCoil Discussion!!

What you'll need are a pin vise (search thread) and some drill blanks or bits. Usually less than a 10$ investment that will let you duplicate your wind result pretty much every time. The alternative a Gizmo, an inexpensive mechanical jig. SupX has made a bunch of videos on both the jig and a couple on hand winding. If you get stuck, hail me, and we'll make sure to get you through. I've taught hundreds of people in S FL and across the country on this method and it's easy. Kids make hoop rings with tension every day.

But the advantage to the vape is uniform performance of the wire and the enhanced pressure and temperature result in rapid vaporization.

Good luck all and enjoy the vape!

Do you think the kuro coiler could build a tension coil in anyway?

I use 28 & 30gs kanthal for no other reason than it's what I bought & a spool of it last a lifetime. I dont have a need to buy every gauge out there.
As far as tension- with practice you can accomplish the same with a toothpick & one of those pen torch lighters.
I've got 4 different jigs which I think are fabulous for beginners & gimmicky for advanced vapers.

 

[vibez]

What is the pen torch lighter for?

Oh man. Prepare to get a pseudo science lecture from Bruce Willis and Cigatron about how wrong you are............
Don't you know you HAVE to do it their way, or you WON'T be satisfied?? You must be an amateur, not a brilliant veteran like them. I'll be waiting for the same key word lecture...... Alumina.....tension.....blah blah blah. Can't we all just say we do it exactly like them so they will stop stalking any and all conversation about coiling, and just let us ruin OUR vaping experience. That Bruce Willis (mactech) coil looks pretty uneven and has hot legs, btw. But it is VERY tense!! [emoji16]

good luck.

Hahahaaa!!!! Unless I'm paying them for their opinion, I could care less what someone thinks about how I wrap a coil.

I couldn't agree more.
Making the same coil over and over? No thanks.

Finally succeeded at making a vertical coil on the RBA.

Oh. My. GAWDS! SO much better!

I'm finding this to be true

What size kanthal wire would people suggest for the rba?

I picked up 28 gauge kanthal and been having very good results the last couple weeks with admittedly amateur hand turned vertical coils based on Rutch's pics a few pages back.

Takes a few tries to get it right, but 7 turns with 28 gauge around what I think is a 3/32" drill bit has been right at 1.5 ohms. The bit is unmarked but what I had on hand that fits the RBA intake with no play - 3/32" is 2.38 mm. I then use a tiny flat head screwdriver to space the coils - it seems wrapping a tight coil was getting more of a burnt taste, but the wick wasn't exactly burnt itself.

Getting the wicking right for the vertical coil is sorta difficult but key. You can't just stuff it down in there. Taking it in steps, and wrapping the deck and coil with very thin layers of cotton pad in strips is working best for me, with extra wraps around the coil itself. It's getting the RBA tube / chimney over that wrapping without it coming undone is the difficult part - remembering to wrap the cotton in the direction of the tube being threaded down (clockwise) helps.

The first couple coils I got right (as I have 2 eGrips), I haven't had to redo, but that was using the wire that came with the RBA kit. When I picked up the kanthal last weekend, I did a couple attempts and one was tightly wound, and that was the one with the funky taste. I've since replaced the first vertical attempts with the RBA kit wire (which were at 8 turns instead of 7) with the kanthal.

I do see the sense in the tension coiling, and will be reading up on it this afternoon - but wondering if my success with the spaced coils isn't an anomaly due to my higher VG content? The juice has the ability to flow through the coil?

(And actually, I've learned that the VG Dekang USA Mix that I mix 50/50 with VG Basic Tobeeco is really 80 VG / 20 PG. So with the Tobeeco being 98 VG / 2 PG, that works out to what, 90 VG / 10 PG?)

Lastly, I did get a tiny bit of leaking out the bottom yesterday on eGrip #2, but I think it was due to me chain vaping at low wattage - I had forgotten to turn it up to my usual 12.5 or 14 watts when I do so. I switched to #1 and cleaned it up and let it sit all day yesterday into today, and it hasn't leaked since. Been waiting for the battery to die in #1 until I try #2 again. I think this might be the drawback to a spaced vertical coil, as it's not heating up the juice enough to vaporize it at low wattage - it's just liquifying it / making it thinner.

Do you think the kuro coiler could build a tension coil in anyway?

Cannot. Rotation coilers bend the wire around the bit. It's external force and that's called forming in the mechanics of physics. Strain is stretch, the second way to shape things in nature is tension, a way to apply it. The advantage of using strain is that you pass the energy actually into the wire. That stored energy results in its wanting to keep it's shape. It will always want to be a coil.

Another advantage is that strain allows you to get the wire as close together as it can to adjacent turns. Compression (squeezing won't do that) as the wire wants to go back to the shape it was originally formed. Strain removes that imprint in the metal and tensioned turns want to go in the direction they were headed…that is, towards the inside of the turn next to it. In other words, the turns always pull in towards each other after they reach adhesion (can't get any closer). Not the place where they were formed. It's a huge advantage when you pulse and oxidize them as you can't get tighter contact in nature. I'm afraid the coilers commonly available can't do that. But the coils they make can be pretty. They just don't function like a true uniformly oxidized microcoil.

The coiler would be a great solution if strain didn't exist and all we could do was compress. The problem there is that to complete a microcoil you must finish oxidizing it. We do this by firing the wire electrically. If the wire has imperfections like a previously carbonized surface the alumina oxidation will not form on its exterior. Alumina is conductive and radiates heat. Carbonation is also conductive…of electricity…and this will make the wind unstable without uniform oxidation (insulation), your wind will go hot (higher resistance).

So the definition of a microcoil is not merely it's shape but it's function, the most important part to us as vapers.

Use strain and you will see a big improvement in your coils and the resulting vape. What's more it's easy and repeatable. Something also on the down side for coilers particularly with thin wire which we're using more these days for variable builds and duals.

Good luck V.
