Micro Coil for the RBA on your REO

[Commie]

You need to coil them like that. If you coil them loose, you won't be able to squeeze them together to make them stay like that.

Oh oh, challenge for Drifter! two resistance wires, in parallel, to make one big coil I'll have to try that tonight

I just can't get my coils to stick together the way you do.

I didn't have as good of luck either until I used that needle tip bottle cap. You can get a great grip on it and the stationary wire tail. Because the shaft is so short, tight wraps are a breeze. It was actually much easier and more precise than anything I tried to use as a mold before.

I use 4" lengths of Kanthal because they allow nice, long tails which I find not only make wrapping easier, but also mounting the coil to the rba. Kanthal is cheap, long tails are money .

That is a fact my man. I tried in previous builds, but the mold was the weak link. I was surprised at how easy it was using that mold. It's a keeper.

Let me know how that dual wire gig performs please. Sounds interesting. My ribbon should be here in a couple of days. I am looking forward to trying it out.

I believe that is the round wire. To my knowledge, temcoindustrial does not sell Ribbon?

True. I hadn't noticed that what you posted was ribbon.

 

[super_X_drifter]

True, but isn't that the same as what you posted?

I hope not the "A" in Kanthal A, as I understand it, describes the composition of the wire, not the shape.

Yay! I got my RM2, put a first coil on (sparse micro coil, 1.7 ohm, cotton ball), it's awesome so far! Vapor, flavor, ease of setup are great. With the white ceramic floor, I can see into it great just by taking the drip tip out.

The hole lined up kinda crappy -- 90 degrees before where I'd like it to be, opposite to the button. So the hole lined up with the squonk hole. If I loosen it up enough to be in the right spot, it doesn't make a connection. Oh well, it'll work.

I haven't managed to fit an o-ring between the base and the cap -- it stops from the cap closing all the way, but no leaking from that seam so far. Incidentally, it helps the leaking in RM1 -- just a little silicone o-ring from an old drip tip, stretched over the atomizer.

Russ, ribbon wire is da bomb. Using a 1/8" screwdriver to wrap coils around so it isn't as small as yours but 7-8 wraps using .6mm kanthal D ribbon wire w/ resistance measuring 1.2-1.3 is giving me tremendous vapor and flavor. Really interested if your microtechnique gonna turn this bomb, atomic. Other than waiting on my ss mesh, I wanna give the .7mm ribbon a try....maybe a lower resistance with my larger diameter coils will damn blow my head off. The reasoning here is the larger diameter will allow more wicking material while still maintaining the coil length (longer coils with more surface contact should produce more vapor). Got my wick legs going around the outside of each post and meeting around the back edge of the bowl opposite the coil. LOL, the back side of the posts are filled with cotton!! This setup is giving me more vapes per squonk. The RM2 is amazing because I can't flood it, so after XL squonks I know the XL wick is fully saturated and its giving me 6+ BIG hits. Good luck on your quest to find vaping nirvana bro

Señor Nutz, after reading this, I can't wait even more for my Ribbon to get here. Thanks for the info bro.

Had to add that I found vaping nirvana with my REO and first RBA. Now I'm just exploiting this new hobby and really diggin tweaking the nirvana to whole new levels!

Need a pic of that coil too Nutziepoo. Is it difficult to get the ribbon in the terminals?

Planning to rewick a RM2 later today so will get pics then. In the middle of cooking right now, wish it was as simple as building a coil .

The .6mm ribbon will pass easily through the post holes. There was another who I believe got .8mm ribbon through the holes also but a tight squeeze....superpoo

Hope you're better at cooking 'cause your attachments don't work.

^ he's right. Damn. Nutz, I admire your dedication to the cause anyway son.

 

[boilednuts]

OK lemme go check cause its werking fer me

 

[boilednuts]

OK lets see if this werks

 

[PapawBrett]

Nutz, are you leaving 'tails' on your wicks and curling them to the backside of the posts? Looks that way to my old eyes...

Thats right Brett, I find that I can get more vapes between squonks on the RM2. Read back a few posts where I better explain this.

Pretty trick setup boilernutzer. Thanks for taking the time to snap those shots .

 

[super_X_drifter]

Thanks Joe! The build in the chalice is on the VVG and it is perfect - I turned the power on it down a hair to make it so. The build in the RM2 on the grand is a little on the agro side, in that it sounds like a small rocket taking off (I also use a very short DT).

It seems that when you twist a coil that small, it may be necessary to build to about 2+ ohms to keep the vape quality in the "mature" range? I'm guessing that its because it is so small that it heats up so hot and rapidly that it makes for a very warm, animated vape? I would probably have dug it if I were about 20, cause its so loud, spitting and boisterous - damn rugged, if you will. But now, because if my vvg, I have come to prefer a more mellow vape. Nothing a few extra wraps couldn't correct I believe. I'm gonna rebuild it tomorrow with about 15 wraps. That should put it right around 2.

The vapor and TH are remarkable in both builds, just a little more "in your face" at grand voltage.

I think that a safe conclusion to draw is, the smaller and tighter you wrap your coil, the higher the ohms you want to target. With fat, non scrunched coils, i liked 1 ohm. With this tiny "wall of wire" I need 2+ on a grand. I'm vaping this as I type and the flavor is ridiculous! Might just keep using it!

My guess is also that the flat wire will perform similarly.

Update: still running these setups, because the taste is better than any previously run (and it was great before). Both vape much more "mature" now. The intense sizzle sound they make when firing them has calmed to a gentle"shhhh" The vape is sublime. Ridiculously sublime. Better than any cig I ever smoked by a mile and a half.

I deduce that once the wick had fully saturated and expanded, it increased the contact with the coil, effectively eliminating the sizzle (like cooking bacon in a skillet sound) and sputter.

Wicks and coils are spotless, no juice in the bowl. Clean. I also observe that with the coil this small, the coil itself, gets immersed in juice with each squonk. The wick appears only to act as a moist baffle of sorts. Defukinliciously pure vape.

Yes, I have to squonk every two hits, but well worth the "trouble".

 

[Commie]

I wonder. Since the coils are so small and tight, they hold juice by surface tension. Do we need a wick? If we squonk every hit or every other hit, can we get rid of wicks completely?
