Here's the design I used effectively. Pretty simple but nothing new. The parts could use a bit of clarification and refinement. Similar designs exist using plastic and tinfoil, though with glass and metal, it seems to have potential in my eyes. Maybe some steel wool instead of a plate at the bottom?

This method is nothing new. I've tried it as have many others here. Unfortunately this is really not a very good way to go about it. All the comments in the thread HERE apply.

Yeah I know it's not new. Someone else had a thread up about the piece they were making and it inspired me to share my design. I know the video referred to in the thread you linked. Although aluminum foil isn't necessarily ideal, I don't think the Alzheimers link is substantiated. Plastic is definitely bad, especially something as cheap as a 2-liter bottle. That design uses the cut bottle, tinfoil and tape. I agree that's not the best method.

But I like the concept and don't see why it cant be a good smoking method. The glass tube (preferably pyrex) is both nice looking and safe, but it needs something better than tinfoil. A metal fixture that holds the spice while also allowing air intake would work well so long as you're heating method doesn't make it burn.

How do you best heat DMT, though? Heat the surface it's on? This seems similar to the method of heating ash or other herbs and letting it spread to the spice. I suppose it'd be most efficient to heat the air around it like in a mini oven. What's the vaporization temperature for DMT anyway?

To be honest, this looks like an elaborate version of smoking DMT on foil but with more space for the vapours to cool a little. Would the holes in the foil/plate/whatever not cause your crystal to leak out?

The idea you're looking for is basically like vaporizing DMT on a swing-skillet typically used for vaporizing butane hash oil. Here's a picture

You heat a titanium skillet with a torch until it's red-hot, then swing the arm until the skillet is under the vapor inlet of your smoking device, and the material is vaporized by the hot metal while the negative pressure generated by your inhalation sucks the vapor into the smoking device, through the water, and into your mouth.

Wow jungleDNBplz, that's pretty cool. That is essentially the concept I like, though I think a straight tube it best for the condensation issue.

Here's a refined drawing. The last one had holes underneath the spice when they should have been on the outside of the plate. I scrapped the plate though for steel wool. The name isn't serious, but I realized it's essentially a "Machine" in this diagram. It's "Clean" because I think it's nice looking and effectively minimalistic. Other "machines" I've seen are old bottles or things.

When all's said and done I'm just sharing an idea. Not presenting this as an innovation - It's just the style I like.

Is this design more effective?

i would consider using a ceramic filter as it will aid in vaporization, but steel wool would definitely work better than a plate with holes..

also why is a tube preferable to a bottle?

This design is pretty much a more simplistic version of The Machine rotated 90 degrees and it's less efficient too. You run the risk of your crystal leaking out of the steel wool when it becomes a liquid.

I don't think condensation is much of a problem in any smoking method. I have smoked DMT out of a bong as either sandwiches from herbs and dmt or dmt enhanced leaf and while afterwards my bong does have this faint tryptamine smell. So yes, some DMT will condense in your smoking device and you're not going to avoid that. Even the GVG ends up with a layer of DMT after a while. This is how I smoke my DMT usually and that means the DMT sits in the bottom half of my bong for 10 to 20 seconds and perhaps even 30 seconds. Issues with condensation become a problem when the vapor has to travel a long distance through for instance small tubing.

If you intend to design your own smoking device you should aim for the following things:
- Should not injure the person operating the device when they blast off and drop it
- Is capable of holding DMT in liquid state without leaking
- Use from a comfortable sitting position (leaning forward to smoke your current design is uncomfortable for me)
- Simple to load with DMT to vaporize
- Easy to apply heat. Heat source should not be able to injure user when dropped or remain in on position
- Easy to clean

But if you wish to design your own smoking device you shouldn't start from scratch. Look at already existing designs. Look at their pros and cons, try to figure out how they can be improved and then work that into an improved design. The power of behind the DMT Nexus is that learn from each other so not everybody has to reinvent the wheel themselves. You didn't need to experiment with various DMT extraction TEKs, different kind of solvents, different methods of recrystallization. Other people already did that for us so that we don't have to go through the same troubles they had.

They shared that information with us so that we can learn from it and improve upon their findings. And many improvements have been made to the TEKs over time by various contributors. You should absolutely check The Inspirator MkII, The Machine and The Key V2. I'm sure that are a few others too.

Learn! And then come up with a new design.

I've considered swapping my tire gauge for a glass tube. The thing can get pretty hot after the second or third hit.

Otherwise I'm fairly happy with my smoking piece considering the time/money investment (it's detailed at the end of that thread Crazyhorse linked).

(It's basically the same concept as the machine just in a tire gauge tube).

Heating the surface it's on (conduction) has been pretty well established to be the worst possible way to heat DMT, aside from hitting it directly with a flame. This is how meth pipes work, and while a few people prefer them most have realized a significant amount of spice gets burned and wasted. Convection (heated air in the proper temp range passing over the crystals) is the way to go. This is how the GVG works.

Oil rigs like JungleDNB described (titanium skillet or nail devices) have been discussed here as well, they have their own problems (namely titanium gets way too hot, and this style device takes more coordination to use than you're likely to possess after a couple of DMT hits).

I make pipes for a living, so I know a thing or two about it. This is why you'll frequently see me engaging in these design discussions. I'm not looking to discourage you or anyone from making or using whatever type of device they might prefer, but try to point out any obvious flaws in comparison to the methods and devices that have proven to be the most effective, in hopes of saving precious spice from being wasted by using inefficient methods.

Something else I think you should take into account with your design, is that while you're trying to reduce your potential condensation area, you are also reducing your chamber size. You can always recover whatever might stick to the walls just by rinsing with solvent then re evaporating (as long as you're not using plastic that is). IMO a larger chamber can provide the full dose in just one large hit, rather than needing 3 or more smaller ones, and is a much more dependable way of breaking through than taking many smaller hits like you are forced to do with something like Edge's tire gauge.

Cyb has come up with a very nice homemade design that avoid the problems inherent with this one, plus doesn't have much chamber surface area. If you don't care for the standard machine design maybe you should look into his?

Assuming the diameter of the device is 2", you would have a total volume of air of about 16 in^3. The draw on a normal pipe takes about 20 to 25 (guessing here) seconds.

Now, imagine the volumetric rate at which you hit a normal pipe. ie, the volume of air you intake per second.

The holes in the bottom need to be small enough that you don't intake the whole volume of smoke too quickly. I've done this. It sucks. I was tripping incredibly hard and on top of that coughing uncontrollably, to the point where I regurgitated in my mouth. It was definitely the worst trip I've ever had but made me laugh really hard when I came down. How dumb can I be? pretty dumb sometimes.

On the flip side, they need to be big enough to allow a nice "draw" of the vapor from the chamber up into your mouth.

I would suggest adding a funnel concept to the mouthpiece to help control the volume of air coming in.



I hope this helps!

Would it be possible to make a simple GVG style pipe?

I was thinking multiple layers of concave screens to hold the DMT.
Then above that a disc that the GVG uses.
The disc would have a wire wrapped around it for removal purposes.


Here's a very crude sketch of what I'm talking about:

i know the feeling

Sure, I don't see why not. It might need a little steel wool pad between the disk and the spice, I believe most folks here use them that way and I'm sure it's for a reason (probably allows better airflow over the spice). But the GVG is really a very simple contraption as far as I can tell, not much to it at all. Their prices are completely insane IMO, the one and only reason they cost $100 is greed.

Thanks to a helpful member I've now got a source for the ceramic disks and will be starting to experiment with using them in various pipe styles as soon as time and funding permits (as well as pending getting re supplied on DMT to test them with!)

First thing I'll probably do is pop one into the bowl of the pipe shown HERE.
