A tale of 2 RBAs

[super_X_drifter]

I see a lot of potential in the aero, def want to pick one up eventually. one question superX, the aero is designed to take air in from the bottom hole, that's why the coil orients itself right in the center of the posts, but since you now basically converted it to a side air flow are you still setting up the coil in the center between the posts? have you tried setting up the coil off to one side, like in an rm2 so the airflow hits the coil as it enters the chamber? I don't think having the coil in the center between the posts is so good when you are now taking air in from the side but can't tell from your pics exactly how you are doing it...

then again I see your chalice also is set up with the coil in the center... whats up with that?

My first build put the coil on the side, right behind the airhole. Talk about an easy build . Except the vape sucked. But the post holes are set up for a side build, in other words they are right on the side of the posts perfectly symmetrical.

On a chalice, the holes are eccentric, if looking straight down on base with a post at 3 and one at 9, the holes in each post are at about 2 and 7. It's made for Z coil between the posts. It would be hard to build one on the side. I think these center hole RBAs are made for Z coils

On the Aero, I drilled my airhole so it hits right between the posts. On the chalice, the airhole is situated so it's almost over behind a post. It's also very low- just above the threads. It's partially in the threads Now as a result of my enlarging the hole to 1/16".

Now that I've acclimated and tweaked the build, and the drip tip doesn't wobble I'd say it vapes pretty much the same as the chalice. That's pretty damn good.

My biggest beefs with the Aero are its height (about 1/4" taller than chalice) and weak grip on the drip tip. Materials and build quality appear good - similar to hornet level.

Just from what I've read I'll stick with my RM2's. Just need one more reo to put the fourth one on.
Super X. Don't worry about copper, it's in multivitamins. The lead, well we got enough of that when we we're young.
I'm confused as to how the RDA's you mention are comparing to the RM2. I can't find anything that is built specifically for a bottom feeder.
And I'm tired of modding RDA's. I just want to wrap a coil, insert cotton and vape.

I like the RM2 best of all the RBAs I've had. It's the easiest to build, ceramic deck, bottom drain, screw on cap and vape equal to chalice. It's low profile and robust.

But... Because my wife has been alerting me about brass / lead content, I'm seeking SS RBAs. I wish Rob made a SS RM2. They're all id use

I like the chalice cause of its exquisite craftsmanship and material quality

With all due respect to the MASTER of the Micro coil. With all the things I've inhaled over half my life in factories, from Iron oxide to Nitrogen envirements, abestios, and silica and a lot of other things, I still thinik vaping is a whole lot better for me. Face it. If it's not pure oxgen then it is harmful to us. But I'll stick with vaping.
Does the Chalice work well with the bottom feeder of the Reo, without a lot of mods done to it.?

which is a maximum of 4% Brass Product Guide - AlcobraMetals.com

I'd be more worried if the Mrs cooks in aluminium cooking pans, but then we all vape them!

Called Reos.

At the risk of being pedantic, pure oxygen is carcinogenic, and will most definitely kill you at high enough concentration

But I'll stick with vaping...

Amen to that.

 

[supertrunker]

a chalice needs no mods to work on a Reo. it's a bottom fed atty. Chalice II

[super_X_drifter]

^ yup no mods on chalice. Except enlarge air hole in my case

The chalice is the prodigal bottom fed RBA

 

[Ian444]

I really wish I'd taken up an offer for a free as-new Myford lathe nearly 30 years ago. I'd be spinning out RDA's left right and center.

Is there some places in China where you can send in a CAD design and get something like an SS atty made? I do it for pcb's, maybe the equivalent machining places exist?

Regarding brass content, besides being a good excuse to venture into other SS atties -aren't all water taps made of brass?

 

[generic mutant]

There's lots of brass in plumbing (probably varies according to where you live), but water isn't anywhere near as corrosive as e-liquid can be, so it isn't likely to be a problem.

I read somewhere it's the acidity of e-liquid that'll do it, but I'm not a chemist...

 

[Matthee]

I'm with Super on a SS RM2. Like the easy build, which why I do not like the Chalice - even if I could afford or get one.

 

[super_X_drifter]

I got this Aero BF nailed now

Turns out that even with the slightly higher coil, less cotton is more. I trimmed it so a very short amount of wick protrudes on each side like my chalice and damn. It actually vapes perfect now.

The drainage was solved by playing with the oring in my bottle. It drains better now.

Took the oring off my drip tip and installed one wrap of Teflon tape in the groove. Reinstalled the oring, pushed in the drip tip and it's tight.

The last 3 days of tweaking resulted in a vape that ranged from the lamest to the best.

Trick is, build it just like chalice with a slightly higher ( by .5mm) coil. Squonk longer and vape like a Rockstar.

This thing is kickin AYuss now

But it's still tall. It's my in house vape

 

[MasterofNone]

Hey Russ so now that I'm doing a google image search on the chalice ( and went to the mark bugs website- d'oh!) it appears the chalice is a side hole airflow bf atty, yes? So unless I'm seeing these picks wrong the aero may be an inspired by type deal, but not a clone or replica... And now I actually want the aero more. So I have two questions for you< for now >
What is Teflon tape, and where do u get it?

And

What is the height of the aero as opposed to chalice. I know they're both pictured but at different height ( because of the vv grand, and I'm slow ha) and I guess also in relation to the rm2, since you consider that a pocketable rda.

Sorry for the annoying questions but the little miss is gonna need the right hat for out on the town!

Tim

 

[super_X_drifter]

No prob Tim. I'm out right now but I'll measure the aero later and let you know as well as answer the other questions

Teflon tape is usually used for threaded plumbing connections. You can get it in a hardware store / Home Depot / lowes.

 

[super_X_drifter]

Tim, here's a 3 way size comparo:

It's 5 or 6 mm longer than the chalice and the chalice is about 4 mm longer than the RM2. The chalice doesn't seem tall though. It feels fairly compact actually. Most of the extra height in the Aero is in the base. I wonder what's in there that makes it so tall? There is one benefit to it though: you can easily grip the base to install / remove the Aero and not grab the cap by default

The Aero is about 1 mm narrower than the chalice too.

If this RBA were 5 mm shorter and it had a Kung Fu grip on the drip tip the way the chalice and RM2 do I would order 2 more and be done chasing RBA's . The vape on it is IDENTICAL to the chalice / RM2. It's DAMN excellent.

 

[MasterofNone]

You are the man Russ! You know what we need? Someone to put these three together... Lol
The look of the chalice, the height and ceramic cup of the rm2, and the bottom air and diameter of the aero... But mainly I'd settle for knowing why the base on the aero is so tall as well. Definitely something to make you go hmmm.

Thank you so much that pic is going in my favorites! Leaning more and more towards the aero in general... And 35 mm isn't really so bad... That's standard carto size I can live with that
Also... I only use one drip tip... Super glue here I come lol

Edit: I can definitely see why you'd say the rm2 is very pocketable. That is one squat device... 25mm is a LOT shorter than I thought it was... Not to try to improve on robs design... But I wonder if the center connector could be drilled for airflow and the side hole closed up...

 

[supertrunker]

i have a better idea - the cost of an RM2, the drainage of a Chalice and err - the drip tip from the Aero.

I suggest what it proves is that SXD can tinker and make any 3rd rate huge atty vape well.

[MasterofNone]

+1 for his err...super abilities

 

[supertrunker]

The RM2 is a modified Triangle atomizer to begin with from Empire mods. The fact that Rob has turned a modified Chinese atty into one of the gold standards of vaping says a great deal about his ability.

Once upon a time it was "killers and chalices" until the RM2. I like them so much i have 14 of them.

I know... Still wish it was bottom air lol. A guy can dream, can't he? P
