Earlier in this thread I posted on 5mm OD glass tube on an AGA. I had a similar thought on wick setup. My longer ss wick was ~3mm to fit the AGA hole, then I added mesh to build out the part inside the glass tube, ID was about ~<4mm. If definitely provided an increased juice reservoir, but added to the startup time b/c of the heat sink effect of the extra mesh. Maybe thinner wall FQ with a similar OD would work better?

Finally got time to make a Hemp ScubaQu. I used 2 strands of 1mm cord and raised the tube ~1mm off the bottom surface. Vape production very good right out of the gate. Best power level was at ~10 watts. At 12 watts it started to cook the juice. With the dud (vs the AGA), best vape production for me was at a 90 degree angle to the wick.
So with Hemp wick, vape is lighter, but smoother and get very hot (Much hotter than the AGA). Taste is as good/better. Overall definitely vapable. Takes a few seconds to get going, but once you are up to temp, its chain vapable. I just cant get power hits like a coil-on-mesh setup. Cant say I'm gonna switch..yet.
I'm thinking that if we had two of these tubes firing at the same time, it could get to coil-on-mesh vapor production. Hmm...where's my drill...
3mm thin tube pyrex with a 28g coil at 1.6ohms:
I am hoping the quartz reduces the lag time. 9.5 to 10 watts is my sweat spot with the hemp.
Also the 30g reduced the lag a little.
Good idea on the 30g. I also have the flat wire which has resistance ~the same as 30g. I am not sure of the comparative mass but maybe I can squeeze in enough coils to test, the wire is .5mm wide! Maybe more metal directly on glass will help too.
BTW did you ever receive your order?
No I haven't, seller says if I don't get it this week he will reship.

That looks awesome! So... does it hit like a beast or what?!
Been doing a lot of check flights and have not had time, will do this weekend.
I would love to say yes. But the honest truth is that it does not. The chid with hemp vaped better.
Its not a vapor production issue with this set-up. (which is great). The issue here is with the top cap on, no matter what orientation to the wick, it just is not working out to a great vape (good but not great). The top chamber here is much bigger than the chid...So I'm doing some top cap tests with airhole positioning to see if I can optimize this thing. so no cigar....yet
Damn and that looked so promising
well thanks for posting and I hope you find the ideal airflow
I'm not trying to play a rocket scientist or anything, but theoretically, wouldn't a lower air hole in the top cap, like just barely above the top base, cause a much greater upward swirl to the exit then anything else? Maybe even creating a vortex? Ok, I've had a couple of beers... Tomorrow is my 'play day' with this stuff again. We'll see. I have a couple of ChIDs to test with.

That is enough vapor to put out a small brushfire!!! Hard to believe you aren't getting enough vapor to turn your gills green..
I could use a rocket scientist. I tested the air hole at the base, at tube tip and 5mm and 10mm higher than the tube tip. Also with wick alignment at 0, 90, 180 degrees. There is something else at play here with airflow dynamics. I'm thinking it may have to do with the difference in vapor pressure with ScubaQu vs coil-on-mesh. Also, the vapor being generated is different. I am pulling together a comparison video. Maybe we can send to NASA for evaluation?
Lol...I thought that too. This produces as much or more vapor than a standard genny with the cap off. With cap on, the vape changes significantly. Still needs tuning...

I'm getting slightly better results without any mesh sticking out of the top of the quartz tube, but only slightly. At best, the air enters at about the height of the tube, is offset by 90 degrees and the tube is above the atty base. Not quite how I want it to be set up. Also tried alignment just missing the tube and using a longer fill plug tube and redirecting air around that. Probably next will be a shorter tube, 8mm or so. Currently it is 11mm.
The nice performers I'm noticing have a nice conical plume coming out the end of the tube, even as in raidy's secret sauce atty.

Fine to publish any results here, just didn't want it filled with theories and ideas to do in the future. Results, good or bad should be published here.

ScubaQu Setup As good as (perhaps better than) Standard Genesis
This is a very easy set-up. Its still in an early prototype form, but it working very well. Using the set up below, I was able to repeat similar performance in three different attys. It is only a slight variation from the original ScubaQu. I have not seen this version posted yet, so hopefully I didnt miss it, if it was posted. The change is to use a hollow wick with a couple of tweaks. (sorta was an obvious alternative .)
This makes sense now after plowing through a half dozen different SquabaQu approaches and seeing what they do well and what they do not do well. I believe the issue is vapor pressure and a condensation effect. Essentially, the solid wick ScubaQU produces its vapor at a much higher pressure and that based up the capability of the venturi (Bernoulli) effect of the genny atty it is too great to overcome. Swirling and mixing with different airhole positions, inlets, deflectors, etc. helped but did not fix the issue (at least for me).
Basically, when flow is pull through the drip tip, pressure drops and condensation forms. The increased pressure drop further accelerates condensation. So, it makes sense that people are seeing good vapor production with the cap off and then, minimal to okay vape, when they put the cap on and vape. With the hollow wick, vapor can be produced at lower pressure, much more inline with coil-on-mesh. I can get monster vapes now.
Enough science, this setup rocks. Grab your glass tube, roll a wick, coil some wire. This is so straight forward, its ridiculous. Just a few key techniques make the difference.
Here is how I set mine up:
Materials:
Glass Tube- 3MM OD (2.2 ID) X 9.5MM length
SS Mesh #500 15mm X 40mm long
32g Kanthal A-1 5/6 wrap for 2.6ohms
Wick Prep:
1) Roll mesh tight around a large straightened paperclip and form an even tube
2) Insert a toothpick in one open end of wick
3) Slowly increase the inner diameter of wick to approx. the inner diameter of the glass. Increase diameter of the wick only for the length of glass (You should have a very thin end and large opened end)
4) Thread smaller thinner end of wick into tube
5) Test for snug fit of larger end of wick in the glass tube. Pull out and increase the mesh hole size with toothpick if needed. (The mesh needs a positive outward springy pressure on the glass tube)
6) Align the end of the wick even with the top end of the glass tube
Coil Prep:
1) Use 3mm drill bit
2) Form a coil with Petar K method drill-bit
3) Insert the wick and tube assembly
4) Position coils evenly and as high as possible on tube
5) Gently tighten coil in place
6) Pulse gently and tweak to even out coil glow
Then: Fill, prime wick with juice Vape.
This should work in any standard genny atty. (Worked for me in Cobra/Chid/AGA-T)
Align the air hole with wick and at wick tip height
When you test vapor production, if the tube is blowing smoke rings, you are there.

You may have a slow startup, you need to get the glass up to temp. At first you will be saying that gdeal is full of ****. Work through it, its worth the wait. If it starts to taste burnt, power down and start the warm up at lower watts. You may need an initial tilt to prime the wick as well.
Start at around 7 watts. The Chid gets really hot and did not need to go that much higher. The AGA and Cobra worked best between 9.5 and 11 watts. YMMV.
If you are not getting good vapor production, check the wick to make sure it did not tighten back up in the tube. If it did, stick the toothpick in to remove and then repeat number 5 in wick prep above to re-expand.
I did notice that as this setup got in its zone, meaning the atty was hot, the juice was flowing and it was hitting peak vapor, I took it down a watt or two and it stayed shining in chain vape heaven. It may also save you from a tank meltdown.

Need to run in a couple minutes, back on line tomorrow. Let me know how it works for you.

The wick setup after removing it from the AGA-T:
Nice write up gdeal. I've been messing for a few hours and then saw your post. The 15mm wide mesh thing was my key too. I was using a pretty solid wick. It's working a treat now with 8mm 3 x 2 FQ tube, 6/5 wrap of 32g, and running it on my ZMax at 10w. The only diff I have from yours is that I'm using 400 mesh. All I have right now. Working surprisingly well, but have to do the 'genesis tilt' when using it. Can't wait to try it with 500 or 635. Pretty tasty vape right now. Nice job man.
EDIT: Forgot to say this is on an AGA-T.
EDIT 2: The taste of the juice is phenomenal. I would also say it's better then coil/mesh. We'll see how it does in the long run.
EDIT 3: It's kind of a noisy, poppy, SOB, but I don't mind. LOL
