Micro Coil for the RBA on your REO

[sbmqcy]

What size did you get?

Sorry--didn't see the reply till now. I got .5 x .1 nichrome ribbon. Haven't played with it yet. Was getting out my cordless drill to drill out my rm2 and discovered that my second Li-ion battery croaked. I'm down to a beast of a corded drill that I'm not about to try to hold up for that long. Not to mention I discovered my chuck key is missing.

How'd that size work in your testing?

Wait - what kind of batteries are you using on a 0.3Ω coil????

I happen to be using the Samsung INR 18650 20-R

The AW IMR 18650 1600mAH would work well for this application as well. (and the MNKEs, and the SONY US18650VTC3)

. . . . but the samsungs are 2000mAh

pdib, the picture isn't showing so can't see coil but sounds killer . I've come to realize that I love the all the vape characteristics of a standard .055" micro coil and the simplicity of wrapping / wicking / maintaining them, so I don't experiment with different build types any more. I do sometimes change wire gauge and modify wrap count but that's about it

All y'all pushing the envelope with these sick builds - keep on rockin

Well I didn't want to jink myself last night but the second build was only .2ohms off target. 1.7ohms. Close enough. Swapped all the cotton last night, day off and I do believe I'm going to spend it with the triplets. Got some Genny style I need to recoil and wick (still having issues with the AGT wicking).
Darn. This reminded me I'm wanting to rebuild the KFL with a micro coil and cotton. Been using ecowool. Just unsure about changing the cotton in the KFL, since it has to be drained first.
And I can now see why you all prefer cotton over gauze. Oh well at least I got a good supply of gauze for the next time I have a boo boo.

.5 X .1 worked good, but .6 X .07 worked better.
Tried 1 X .05 and IIRC .8 X .1 and not so much.
.6 X .07 was stumbled upon while searching for .6 X .1 and it was so cheap I ordered some of it.
I never found any .7 X .05 but I have a hunch it would be ideal if it folded correctly.
Would also like to try Nicrome ribbon but couldn't find anything close enough in area / resistance to warrant a try.
Still going to give a go at making Rene 41 into ribbon one of these days, but I have a totally different direction atty wise I need to explore first.
Time is not on my side right now due to work load.
Speaking of which, got to end lunch and get back at what pays the bills now.

Hmmmm... I am fascinated.

So I ordered a couple Sony SE US18650VTC3's for sub ohming - they are rated at 30A, but are only 1600mAh. (LOL only) Do you recommend the Samsungs instead? Just thought the Sonys would be safer.

Lowest I have built is .42. Truth is, I can't vape anything but zero nic at this range. My 6 mg is too much. So it's not an every day vape for me. Also I've discovered I don't have the lung capacity to suck in the kind of vapor needed to blow out the crazy clouds they do in the Youtube vids.

\What I really want is a build that will produce crazy vapor with just a small, girly, mouth-to-lung hit. LOL suggestions?

 

[pdib]

Safer-wise, I haven't looked into the chemistry of the Sony's (maybe somebody else will chime in). All the aforementioned batteries are plenty safe as far as Amp ratings and track record (although the AWs and then the MNKEs have been around the longest . . . .. have the longest track record). The storage capacity of these batteries (mAh rating) is really just about run time. I'd only consider getting something other than the Sony's (in your case) if they happen to be awkward in my daily schedule. Lastly, the higher Maximum Continuous Discharge Rating (Amp rating) is indicative of lower internal resistance (so, better performance from the battery . . .. like with voltage drop) . . .. but all these batteries I mentioned have such great performance that it doesn't really matter.


If I wasn't into modding firing pins, and/or Rob wasn't about to come out with some fancier pins, I'd stick with button top batteries (the AW 1600s). That's what the REO's firing mechanism was designed for.

 

[pdib]

Well, I lied a little. You can compare the Samsung INR 18650 20-R to the AW IMR 18650 1600 here. And you'll see that at any given moment (15 min. in, 20 min. into battery use), the Samsung is hitting harder (because it's drawing from a bigger reserve).

BTW: you can select and deselect different amperages with this chart. (try 5A and 7A)

 

[Vwls]

Run times don't concern me much because I only mess around with this stuff when I'm home and have access to fresh batteries, recharger, multiple mods, etc. Not like I'm going to run out of vapeables. Safety and quality of performance are my top concerns. But I was curious about your battery choice on a 3 ohm coil. I'm still nervous about sub ohming, even though my curiosity and need to tinker always win out.

I want to build this in my Trident:

Or... something similar...

Would this produce massive clouds of vapor without having to take crazy deep lung hits? Are there any videos of someone vaping with this build? Mundy, I've been watching your tutorials with great interest, but haven't seen any where you take a vape for the camera

 

[pdib]

If you're concerned about safety; be sure to know how to calculate it. If you plug in the resistance you want to check and 4.2 volts on this doo-dad, you'll see what amperage you're drawing. Make sure you know the max continuous discharge rating of your batts. (the 30 Amp Sony is a no brainer).

I'll leave our dear Mr. Mundy to answer for his lack of cloud vids.

Wish I could get my hands to work right. Would love to try a coil setup like that.
I have a hard enough time trying to make a simple 1/16 wrap and get it in the holes.

 

[Xobeloot]

it's actually pretty easy. just wrap your normal 1/16" micro, then mount it, tighten down the legs but place the coil as close to the rim as possible. if the right post has the wire on top and left on bottom, rotate the coil CCW to desired position and adjust legs if necessary. If right is on bottom and left on top, rotate CW. With the legs already cinched down, the rotation will pull the coil a tad inwards so there is no worry of shorting it on the cap. Leave the jig inside the coil so when you rotate it, the legs will just continue the natural wrap of the coil with no slop and very little (if any) final adjustments needed.

Easy if you can see what your doing. I've got arthritis in both hands so it makes it a bit of a challenge sometimes.
And I only see out of one eye. No depth perception.

The meat grinder in that picture comes in around 0.4 ohms (0.8 ohms per coil).

If you are cloud chasing there are setups with conventional wire that will out cloud twisted magic.
I am not a cloud chaser so someone else will need to point you in that direction, but I would say most if not all are sub ohm.
Cloud machines have a reputation for low taste as I understand it.
The vapor from magic seems to be less dense than from comparable conventional coils.
I think it might produce smaller vapor droplets which would explain both the "whispier" vapor and enhanced taste.
If you are looking for taste, that is where magic shines.
I normally vape a single micro coil of magic in the 0.8 to 0.9 ohm range with 6 wraps.
The bee and monkey like it lower in resistance with less wraps.
Others have reported a higher resistance coil with a VV set to higher voltage works well.
At least 1 thought it had too much taste but reducing the voltage was where it shined.
To each his own as the old saying goes.
As soon as I can I will follow through with your sample piece and you can see what works for you.

Lunch is over so got to go now.

too much taste? Is that like too much sex?

What is the metallic composition of ribbon. Is it the same as kanthal? I have an aversion to nickel, so I have to be careful of what I use for my coils.

Thanks for this explanation! I had seen this coil and it looked like to much effort.

My coils are already really close to the cap anyway, so I just took out the wick, turned and voilà:

I think I'm in love! Thanks again!

we should team up. i have old man eyes, and one hand that actually works.

i've used the phrase "bit of a challenge" publicly myself. privately, it's all expletives...

What I use is Kanthal A, it is just in ribbon shape instead of round.

I can cure old man eyes. Magnifier light. The depth perception is still a _____________________fill in the blank.
Don't believe me then take a ride on the beemer sometime.
