I am considering making a pipe mod, and am thinking through a few general ideas. First, please bear with my ignorance, as I have never smoked a pipe before, and have little understanding of the design considerations that have gone into the various kinds of pipes. I have done a little reading, and see that there are really a great many things that are part of a tobacco burning pipe, that don't apply to an E-pipe.

The main consideration is that I would like the pipe to be something you feel comfortable holding in your mouth for an extended period. Here are some design points that I think may help this issue.

1) Light weight.
a) This means that I probably won't want to use a steel atomizer like a Vivi Nova, thought I like that atomizer. Probably something plastic, like one of older style clearomizers. (the traditional cartomizer doesn't hold enough juice for me).
b) Light weight battery. I am satisfied with the life-span of a 600mah battery, but think the weight is a bit too much. So, am now looking at a 350mah battery. Perhaps if there is a charging base that doesn't require me to plug anything into the pipe, then it will be sufficient.​

2) Engineering wise, the location of the center of mass, as measure horizontally from the mouth, should be as short as possible.
a) The pipe mouth piece needs to be fairly curved, to allow the bulk of the mass to be below the mouth, and therefore not as much out horizontally.
b) The main weight source (i.e. the battery), should be located nearest the mouthpiece. This means the atomizer itself would be located in the bowl, which is of course, backwards from your typical e-cig. But, see the drawing at the end to see if it makes sense.​

3) The stem needs to be firmly fastened to the body, without risk of falling out.
Traditional pipes seem pretty sturdy. But, the standard e-pipe mod seems to avoid using a traditional pipe stem, and just put a normal atomizer at the end. Those typically have a flat rubber mouthpiece that can be held between the teeth nicely, but easily slide out of the atomizer. Alternatively, many have a round metal one that is threaded. But of course, you don't want to hold a round metal piece in your teeth. Furthermore, the shape is not right for what I want.
If the atomizer is not in the bowl, then I might make a special cradle that holds the atomizer, and structurally supports the mouthpiece, but it would have to be designed for only one style of atomizer. Perhaps in my backwards version, the pipe stem can be permanently attached.​

Here is my pipe concept drawing. Please comment if any of the points above seem unnecessary, or just wrong

As I look at traditional pipe designs, none seem designed to be optimized geometrically. My overall shape is present in some classical designs, but that style is typically much larger than what I have in mind. They were obviously only hand held. But, traditionally, pipe smoking has been something you do while relaxing, rather than sitting at a keyboard with both your hands occupied. If you needed to think and write, you only wrote with one hand, and could hold the pipe with the other. There were also super light weight options, like corn cob pipes, if you wanted to hold it while you worked with both hand.

I understand what you want to do in theory, but the ideal situation would be the battery in the mouthpiece (or in your mouth) and everything else stuck on to that to get rid of the leverage/weight problem. Going by the diagram, I'm really not sure if there would be a noticeable difference if you put the battery in the bowl and just kept the vertical approach with lightweight components.

Let's just take the diagram at face value and look at one issue. If you pull air through the atty backwards, condensation and gravity are going to work against you and quite soon the plumbing will be full.

I've never tried an auto batt ecig of the 'natural' look and feel, but there is no doubt that the 'small' package is heavier than some dried leaf wrapped in paper with a filter on the end. Not just King size but 100's or Wides too.

most of the vapor will condensate on that tube you have and will not give a good vape, it's too long and too thin... test this by attaching a long thin tube to an existing mod to see, plus gravity will work against you and drawing from the bottom of the atty will fill the tube up with juice too, so overall I don't think this will work at all and is just a bad design... on top of all that you still have all the weight in the end anyway, not going to make much difference weather the battery is closer since it's still hanging way out there, sorry man, just calling it as I see it

Thanks for the commentary.

I had not thought about condensation in the tube. Though, if the tube is large enough, the condensation can drain down to a collection chamber at the bottom. But what to do with that condensation? Perhaps if the collection area has a coil that occasionally heats up, and it can re-vaporize the condensation... but things are now getting more complicated than I planned.

For the material of the tube, I was thinking about a brass tube. The pipe stem could be from an actual pipe, if I just seal the brass tube at the lower part of the stem.

Turbocad6, first, I want to make sure you understand why I referred to the horizontal distance of the center of gravity. Though, with TurboCAD as your handle, you probably already do. But, for others, who don't have engineering training, perhaps an illustration is a good idea. First note that my atomizer is a "eGo style" clearomizer type, with its rubber mouthpiece removed. So, it is all plastic. I don't have a scale, but guess that it weighs less than 1/4 of what the battery weighs. The location of the center of gravity is more influenced by heavier things than lighter things. Note that the body of the pipe also contributes to this. My drawing of the CofG is just a guess, rather than a calculated position.

After making the drawing, I am less convinced of the value of my original design from a weight perspective. But, there were other design motivations as well. By using a strongly hooked stem, the weight can simply hang down, vs. having to be gripped between the teeth. I know there are the "Sax" atomizers, but the mouth piece is not screwed on, nor is the shape bent enough to hang from your mouth.

I purchased a pipe-stem adapter that allows me to use a standard pipe stem and plug it into a standard "drip tip" type atomizer hole. But, in my mind, this does not firmly secure the stem enough to carry the weight. I may be able to resolve this by pinning the drip tip in somehow. Or, alternatively, maybe the stem is made to hold the atomizer like in the illustration below,

I don't like the look of that cut-out. But, perhaps some other variation can be made, like hinging the stem, and putting a clasp on the side opposite of the hinge. You know, this starting to look like the standard commercial e-pipe, except that I am trying to use an existing cartomizer rather than their special cartridges.

I have been through several types of atomizers, and so I wanted to allow for me to continue to have the flexibility to use any atomizer. A benefit of having the atomizer in the bowl is that I can put any atomizer inside. For the clearomizer, because it is filled with the absorbent material, there is no concern of leaks, so there doesn't need to be a top on it. This makes re-filling a breeze.

But, after using E-cigs for a while, I have pretty much settled down on what I want to use. So, perhaps I can just settle on one particular atomizer style, and make the necessary modifications to it. The atomizer inside the pipe stem is looking more attractive to me.

I do understand your thoughts of keeping the battery inboard as much as possible, but the amount of bad in that design would just outweigh the small benefit of that alone, and honestly I don't see that small of a difference in placement making a significant difference in balance, enhancing the curvature and shape of the bowl and the stem would better serve towards compensating for the balancing issue rather than going with the first design I think

I like the atty in the stem, that's a very good design I'd say, what if you do your last picture, but threaded at that joint instead of hinged? I think that would be perfect and might be usable with more than one atty type too, you could use an adjustment ring to clock the stem straight when tightened if you do threaded. another possibility may be a keyed slip fit, but you'd still need a creative way to lock it in place. it might make sense to consider fit of other atty's at the design stages of course, small tweaks of the design may open up other atty possibilities as your building it, depends I guess on what atty's you have in mind and how much differences there are between them, sometimes it may just be best to design around one best atty though, guess it depends how similar the candidates are and how many compromises may need to be made to go with a wider range of atty's. looks like a very cool project man, hope you build it and enjoy it

I've used an upside down atty on a version of my GUV epipe... Juice feeds down from the hole on the battery connector. I've put up more detailed pics on my This is not a pipe thread.

I had glossed over that thread in the past, and just now went over it in more detail. I am having a hard time keeping track of which pipe is which. You refer to the MK2 GUV pipe, http://www.e-cigarette-forum.com/forum/modding-forum/366280-not-pipe-7.html#post9509459.

I somehow missed the fact that your atomizer is in the bowl. Is that correct? I think your battery is in the bowl as well.

What was your motivation to arrange things with the atomizer in the bowl? Are there any issues with condensation along the vapor's path to the mouthpiece?

The atty is in the stem, just that the air inlet comes from the bowl rather than the stem so that when puffing away at it some vapor can exit the bowl for added realism. The general direction of the airflow in this tube however keeps it self cleaning.

edit: sorry, I'm referring to the MK2 GUV here.
