I wrote a quick email to Thompson Enamel to ask if there was lead in their products because I read that some enamels used on metals contained lead as part of the mixture, and they responded with a big "No" none of their products contain lead

Shoot me your info, LucidAce. You need to let me know what exactly you're looking for size-wise. I'll see what I can come up with.
Awesome, TBinAZ! I'll take some measurements and then get in touch. Thanks
nope not talking about that one...just one of the pics he posted at one time...the vapor just follows the same pattern...sort of shoots out from the tube...
and Perlionsmitnick.....is your hutt avi changed...it looks different somehow....
and was it the coil...or the wick he said it could do without...hmmm I need to go look...must be getting old...arrgh...eyes and now memory...somebody shoot me

A small update. I was vaping pretty well with the 2.5 thin wall and since I had to keep fooling with it I blew a coil and then ran out of time to do such things for the day. The small wick I used was working and you could see the juice boiling up between the wick and the glass. I was getting good results on my Zmax set at 6.5 watts stacked batteries. Note that my Zmax is a v1 so that may make a difference in settings if others try replication.
I noted from a dead cold start that it takes a bit to get going. I'm guessing 2-3 seconds. I think I may have better results with a bigger wick and I did have time to build that wick and get it in but then blew the coil. Since I could already hear my wife tapping her foot I decided I'd have a go with more trials tomorrow though she did indicate I'd be rather busy.
My take is there is certainly a good potential once the various parameters are worked out. I like this thread for all the crowd-sourcing R&D going on. I thank Dan for his getting our juices vaping.
I'm very interested in several of the ideas and think we will get a better mouse trap. The other thing to consider heavily, and there are some posting ideas, is a rethink of the tank atty. With the ideas rolling along we should consider that there may be ways to design a tank atty to take advantage of some of these ideas as well.

Just to throw and idea out in case someone might find it interesting enough and have the time to try it. I had toyed with a juice delivery system that uses a misting system instead of wicking. The problem of course is pressure for the juice. It would be fairly straight forward to find carburetor jets to start the atomization and then put that through a heat stack based on the glass/coil.
The thought then came that we have the required pump our hands. Think of a Gripper with a squeeze pump to pressurize the juice. If done well it wouldn't really require that much pressure and you'd give a squeeze and fire giving you a hit on your vaper.
Maybe I'm just over thinking/engineering it. It wouldn't be the first time.

Yeah I has this thought too. I don't have the engineering skills though. It seems to me that there would be challenges to work out though with miniaturization and controlling the flow. Additionally you would need to figure put the right heating/vaporizing surface.

funny thing...there are injectors that small...see 02,03,etc etc. Chevy Tahoes...man those things are a pain to change...cant change just one...has to be all eight
...couple of observations while vaping my latest ScubaQu set-up. I was playing around with different settings to optimize the vape.
I made a few changes to the set-up here: http://www.e-cigarette-forum.com/forum/modding-forum/351986-pyrex-ss-hybrid-wick-28.html#post7878614
The primary change I made was to reduced resistance from a 1.7 ohm coil to a 1.5 ohm coil to speed up heat-up time. I did this by shortening the bottom leg run to the negative by creating wire contact closer to the wick hole base and by using two m3 stainless steel washers for the positive post. I also pulled the wire a bit tighter.
With a 1.5 ohm coil, heat up time is a bit shorter for the 28g. It still needs a second or two from a cold start to produce, but once the SS wick was hot, it was almost instant-on with vaping. This was very noticeable when chain vaping.
The big thing I noticed was that vapor production and QUALITY improved significantly. I was sorta scratching my head on this one, but upon a closer look two thing became apparent; The washers are ~ at the height of the tip tube/air inlet hole and when I looked down through the drip tip opening in the cap you cant see coil anymore, only the top of the washer. So it looks like the washers are adding some type of positive vortex effect.
The next one gets into a grey zone for me , but with the 1.7ohm coil, if I went above 11.5 watts, the juice felt a bit cooked. Its a bit different taste then the burn taste on a traditionally genny coil on wick. With coil on wick, I saw someone used the term grilled (Dsy5?). This was more like over boiled.
In any case, the point I wanted to make was that with the 1.5 ohm coil, I could get to back ~14 watts before quality went south. Either eliminating a few mm's of non-coiled wire and/or adding the washers really bump up performance.
So this is working really well right now. I actually dont feel compelled to switch back to a traditionally genny. It not yet better overall, there still is a bit of a minor trade-off in vapor quality and time to start-up, but with flavor and set up time its almost better. With some more optimization, this will replace coil-on wick.
Dan, if you can squeeze a washer on top of your positive post, let me know if I am on the right track here with the air flow effect or if its just sleep deprivation playing tricks on me.
Long live ScubaQu
I believe that the Zen atties use a similar concept, so you're probably not far off thinking that
Found a local supplier that will send me a sample of Quartz tubing 3 mm 0.7 mm wall thickness....
will try to stack 3 small pieces on top of each other to see if the space in between those piece will have vapor coming out from the sides instead of only from the top....
More of a challenge will be to drill tiny holes in the Quartz, but doubt if that will work as it is so thin and fragile....

Monty, you got me motivated to try harder, I found a company that has 4mm OD 2.3mm ID, which I am afraid is just too big and thick, but at least it is something. 1m= ~$6, not sure on the shipping though.
If there are holes or slits, then juice is back on the coil, and the gunk returns, bleh. Going on Dan's results, I am confident that we can get enough vapor out of the top of a tube, and it is a matter of airflow for that. My mouthpiece is 21mm long, with an airhole 7mm from the bottom, so I plan to just turn this tube upside down and be 14mm from the bottom and hitting the top of the Quartz.
I am curious about how this is working so far with respect to splatter and or condensate., as that could mess up the coil too.

asdag, yes true but if it works with current RBA's I would not mind a bit of gunk, as there will be no hot spots anymore and putting a fresh coil around it once in a while will already make it a major improvement . But I agree the quest continues to make it perfect. there are so many great minds pondering, experimenting that it has to happen!!!!!
The three chamber design sounds decent, but I'm pulling for doing it with two.
I also don't think we are in raidy's newest design here, he has published glass tube stuff before, many of his clouds are spout like, and the whole with or without kanthal part is just mysterious.
Dan, how it the condensate doing?

+1 on two chambers asdaq.
But if we need to go to a three chamber redesign, here is an atomizer design concept already in production. It a bit too big at 250mm. I have no idea of the cost...its titanium.
EDIT: Just to clear up the my thought here... This type of component would be used as the top connector for an isolated coil chamber and a top expansion chamber. The tip of the glass tube would be place in the center cone.

When I pull the top off the condensation is the same as a straight SS wick/coil setup. I leave the fill holes open on mine for air exchange with the tank, not sure how much is pooling and flowing back into the tank if any.

250mm might be good for tabletops or at parties...
With 'chamber', I see it as space that can hold liquid or air, which may not be ideal here. With three 'sections', we already have three counting the intermediate piece between the two chambers. Trouble is it needs to take heat and be non-conductive.

Still behind, so forgive me. LOL
I haven't tried it, and have no clue where to get such a thing.
I did have an apex alpha, and was never impressed with the "juice well" aspect of it. Maybe I'm just "special" and never got it to work right. LOL
Since it wouldn't work well as a wick.... but I think I also read where it wouldn't work well as a barrier due to low heat transfer.
