I thought we got past that, running the tube down into the cap does not work, all it does is make a spurting volcano. Hey guys please just put your results on this thread, good or bad, no theories please; working models with pics and videos preferred so we can compare results.
gdeal; I like your set up but the smoke rings bother me, it shows me a lack of efficiency, like and on off switch on the wicking. An efficient wick would give you a steady constant vaper. The small wick can not provide the juice necesary and with a hole in the center it is compensating with juice being pulled up from the risng thermal action under the coil. It vapes and goes dry, gets hotter and new juice rises and again vapes and goes dry gets hotter new juice rises, over and over again. Using what you started I have some ideas I will try tomorrow but with more wick and 635 mesh.

Have you tried this setup yet, BJ? It works remarkably well for me, and I'm using 400. Almost through a full AGA tank already. Very low heat up time and I'm getting plumes. I may try a video in the morning. We'll see.
Agree with that. Much smoother and tastier...
Just a first prototype. BJ. Its definitely need tuning. At first I didn't think a 15mm width of SS mesh would work at all. I provided a link to the test fire video because when you initially start up it does the inefficient smoke ring thing. But then it kicks into gear and the smoke rings stop. The video is actually a lot longer (it got shakey and blurry, so I cut it short), but toward the end of it you can see vapor production evens out. Once it warmed up it had continuous vapor production.
635 should help, I wish I had some
....I was thinking that about placing a solid wick in the tube to just under the coils would help. It also would be interesting to see the trade off between layers of mesh in the glass tube and performance. One thing I noticed is that there is no volcano effect and the tube stays open..so far.
Ok. I'm on around 2.5 tanks using gdeal's wick method, and the performance is starting to diminish. It's taking a lot longer to produce the stream of vapor now and am hitting the cutoff on my ZMax too soon. I sense that the mesh is starting to get gunked up. I'm sure it didn't help matters to use a naturally extracted tobacco liquid for my testing 
I tried making a video this morning, but I just don't have the correct lighting and it totally sucked. After 3 takes I gave up for now. I will try again later.
I'll pull the wick to inspect it when I get a chance. Have to do some chores right now, but will be back later this afternoon.

...any opportunity for dry burn?
I have now tried 8 setups with many variables, on a DUD, a Chobra, and a AGA T, and honestly I give up. They are all good but not great and the extreme heat generated in the cap prevents me from using any as a sole unit chain vaping. Testing on PT's because of timeouts on Vamo, Vmax and Lavatube. The best so far is the quartz with two threads of hemp, second the quartz with 4 Lydia's bamboo threads, and third the SS 500 and 635. The SS gets clogged internally with gunk pretty fast. The three I did with the tube counter sunk into the cap were crap. I have used 32g, 30g, 28g, and 30g flat wire. I have tried wraps from 3 to 10. The best I was able to do was about 60% of what I consider my acceptable value. Unless someone comes up with something revolutionary with these, I am moving on. I do like the flavor but the low vaper volume and high cap heat are killers for me. The physics of heating the juice to vape temp and getting it to all come out the top of the tube is more complicated than what I want to get into now.

I tend to agree. This is way more hassle than oxidizing a wick. At one point I was surprised and thought I was vaping the wrong mod, it was as good as a standard geni. Turned out juice was getting on the outside of the tube and vaping with the coil. After about five minutes the coil was stuck to the quartz and the gunk had to be scraped off with a knife. 
Also tried a coil inside version with about a one inch length of tube, but after all day working on it and trying out all sorts of decent ideas, only wisps of vapor no matter how long it ran.
Bottom line for me: TOO MUCH HEAT INSULATION.

Waiting on "manu", he is the ceramic expert and has been working on it for a long time.
Ok y'all. Here is the video I was trying to make between honey-do's. Kinda sucks, and it's big, but oh well.

It seems like you're getting lots of vapor and you said you're lining up the air hole with the wick I was about to give up experimenting this set up, I might try it, I've got 2 AGA-T like yours coming from a Coop they look realy good on your Zmax!! Thanks for the video!!
Before I did the video I pulled the wick and scorched it with my butane torch. I opened up the coil end of the wick again with a toothpick and then reinserted it into the tube. I'm pretty convinced that it was my original choice of juice that messed with the performance of my original setup.

TBinAZ - Great video. I think that may be a first for a head cam perspective review. How did you do that? Is that a "Go Pro"? Very cool.
Your vape looks very similar to what I am getting out of my setups. I have no problem on double/triple consecutive pulls. Mine starts out with some vape rings, then goes full throttle too. It does not have the fireworks of coil-on-mesh, but the vape with cap on is great. I need a bit more cold start-up time with pyrex though, more so intentional to minimize any potential for thermal shock to the pyrex.
I am vapping a VG peppermint/menthol juice that runs very clean, so I have had no clogging problem yet. I have experienced the vape drop off after every tank or so. But I just pull the wick and re-expand with the toothpick and I am back in action. No cleaning needed yet and I am three tanks in. But it only takes under a minute to readjust and expand. Not sure why the mesh tube doesn't keep that outward pressure on the glass. BTW I am using the same setup except for the mesh which is #500., and around a 10watt power level.
Thanks. My setup is basically your setup, or should we say scubabatdan's setup sort of modified.
Ya, I was snapping some tubing in my gear room today between errands and saw the helmet and camera. Figured why not. I guess it came out alright. Not good for closeups though. It's awesome for outdoor action. It's made by Contour.
I switched to a clearer liquid after trying the tobacco stuff, but man does it taste rank mixed. I didn't want to disrupt what I had going and pull it apart to clean just yet. Kinda cool to be able to just pull the wick out and do whatever.

3mm pyrex wrapped with flat kanthal then semi-enclosed with 5mm pyrex. 15mm #500 mesh tube with an expanded center hole and then a 40mm solid #500 mesh wick inserted into the center hole. I get good consistent vapor production with the cap off. The hollow wick provides a much better quality vape than a solid wick with the cap on.
It does not solve the overall airflow issue, but the outside tube provides a bit of insulation to airflow cooling the coils. Slight improvement, not revolutionary, but very vapable. Much less efficient than standard genny and gets hot! Still experimental... needs work.
Just thought I would share the concept. BJ hope you don't mind if we continue on your thread.
