Since I shelved my flowerpot after my third burn (I'm clumsy!) I vote for a LOG! Typically I load .2-.3 per bowl. So fun watching the progress @invertedisdead !
The straight glass adapter for the Alpha fits perfectly into a stempod.
Does not sit deeper, closer to the heater.
The only difference is one is tapered and one is straight.
There is a significant improvement in performance with the straight wall piece.
I have seen this across a few vapes now so maybe lose any taper at all if possible?

In an ideal scenario, not taking into account current design limitations, what kind of grind would you like to use, and what kind of flow would you like in the herb chamber? Obviously the flow through the beads will be turbulent, but are you seeking to have the flow even out and be laminar by the time it hits the herb chamber? Or were you hoping to have turbulent flow in the herb chamber, which could have a "mixing" effect, tossing the bud around in an un-tamped bowl?
Many pages back you mentioned disliking grinding, and wanting to potentially be able to use whole buds or coarsely broken buds? I also remember you mentioning a preference for a wider bowl, versus a taller, narrower bowl, is that still the case?
And of these factors (along with the desire for a glass herb screen and glass bead retention) do you have a priority of which are most important to you? I ask because I think there will be some give and take in prioritizing certain of these desires.
If I understand correctly, your primary goals are for excellent flavor, and minimalist design, but I wasn't sure how you prioritize these other factors.
Are you still using the arm as an air intake, or are the 4 holes on top the intake now? Or both are intakes?Hmmmmmmmmm

Stay up homie.
The air outlet slits are interesting. I'm probably not understanding them correctly, but it looks like once the vape sits inside of the joint, the horizontal slits will be blocked off by the joint itself. I'm struggling to understand how air exits the slits and helps create a vortex once the piece is in the joint.Cheers my dude!
In wanting to go back to some sort of glass screen, or glass retainment system, a challenge has been how to add the terp pearls. In this rendering I was thinking why not just make the inlet holes on top large enough to load them in the body that way? The air outlet slits would be sized to retain them. The only time this vape gets turned upside down is to check if the bottom screen has moved; if that issue was eliminated with a fixed screen, I don't think it would really get flipped over. Also, the horizontal air outlets should vortex the air for a more even convection roast, word to some of the OG heavy hitters which came before me!
I would ask them to make it with the fixed screen at the bottom and a removable screen/lid on the top with catches that lock it to the main body somehow. And a hook on the handle so you can hook the coil handle on there.
Are you finding round holes an issue in the lower screen?
I get balls nestling in the holes and blocking them up when I've used glass screens with round holes in my builds.

You mentioned it before in a post, but what's super cool is that you have found someone who can/will do some cnc on glass. That's huge, and I'm looking forward to seeing what you come up with with that kind of ability to keep tight tolerances.
Curiosity got me and it seems machining quartz takes the same tools and knowledge as machining steel.
Just takes diamond bits and a water drip.
You can literally use a drill press and milk jug with a gravity fed cooling system.
You can just get the basic shape as blanks then just make them shits the right way yourself.
Gonna have to bring all that in house homie....... the only way to assure QC.
I think the side air outlets is a really excellent idea. Especially if the user is able to change the angle at which the heater sits in herb housing while hitting it, further contributing to the turbulence where the hot air hits the herb.
One of the reasons I think turbulent flow may be beneficial here is to reduce hot spotting in the middle of the load. With laminar flow the air in the center of the pipe has the highest velocity, and there is a continuous gradient from the boundary layer at the pipe wall (where the velocity is zero) to the center. If you draw a velocity profile of the laminar flow, the shape is parabolic (as shown in the attached figure). With turbulent flow on the other hand, the various velocities average out, making the velocity profile more of a U or bracket shape. The velocity at the wall is still zero because of the no slip boundary condition, but in the middle and approaching the boundary layer, the velocities average out, resulting in a more even velocity throughout most of the pipe.
Now the effect of how the weed is packed complicates this significantly. With a fine tamped grind there is some resistance imparted by the herb, and the air is forced through finer channels in the herb. But if you want to keep the herb coarsely ground, while also avoiding hot spotting, I have a feeling (and I could be totally wrong here) that the trick may be to encourage turbulent flow between the heater and the herb.
The side air outlets also will help prevent any bud fragments that happen to get blown around from getting into the heater.
Now you're just being silly..............Dr. Evil is retired.What kind of fastening mechanism were you thinking to secure the top? Peg and hole?
I've been using the 710coils clips to wrap around the arm and hold the coil; but I recently found that alternatively, you can stick the coil arm through the hole in the O-ring, and the clips will secure the coil. Though I don't notice much of a difference between those two.
My concern with removable parts is I fear it could get very cost prohibitive unless it was a relatively simple solution. I'd have to get some quotes even on the design above as it could be cost prohibitive as well.
Though I wonder, perhaps I've spent too much time trying to deduce this design down to something more affordable, trying to build McLarens at Mustang prices.
Right now I'm retaining the pearls using the lid from a Mighty dosing capsule (cringe!) with a 100 micron SS screen below that which is just large enough to wrap around the sidewalls of the capsule lid. The extra ridgity of the capsule lid puts tension on the screen and does a relatively good job of holding both in place against the quartz. And I haven't noticed pearls blocking these holes, I think they are ~1mm holes on these lids. What type of glass screens have you used, were they a honeycomb style?
I figured somebody might point that out, so what I was thinking is if you increase the angle of the taper a bit more than the standard 1:10 on a typical glass joint, it should give you the space necessary for outward flow. I notice when using tapered components in these joints as long as the taper is wide enough to block the airflow at some point in the taper, it seems to works relatively fine. The entire taper doesn't seem to need to match eachother since we aren't refluxing chemicals or something, so the seal is less critical. Currently the top down airflow seems to not really expand wider than the diameter of the air outlet itself. By switching to a side outlet, I'm thinking that would force the airflow to span the full bowl better, and that "spotlighting" effect should be gone since the air would not be coming straight down like the current path of least resistance.
As far as the vortexing, my understanding of fluid dynamics is fairly basic and something I need to dedicate more time to, but other well regarded vaporizers which came before me use similar side outlets claiming it spins the air. Interestingly, I notice these heater designs which also sit inside the bowl like mine, are the same ones that tend to use some sort of this vortexing component. In theory I can see it making sense that a more gentle top down flow could reduce chances of hotspotting.
You can skip the diamond bits with a laser!
What I notice on my current prototype is the flow just doesn't really expand once hot air exits the outlet. Previously I had thought the hot air traveling the full length of the joint simply needed more "time" to expand, but with my latest version which just sits on top of the joint has has basically the full length to expand, it seemingly doesn't. If the temp is set high enough to hot spot, or "spotlight," I notice the hot spot is basically identical in size to the diameter of the air oulet. For some real basic fluid dynamics lessons, I went to the sink, turned on the faucet, and watched the water run through it. Same observations, the flow never expanded further than the diameter of the nozzle.
I agree that it seems like, (at least in my head) that the side outlets would help create a convective flow (crashing against the sidewalls of the bowl and spinning the air?) which should be a less "directed" flow than the current laminar exit. In my head that's what it would do, but I need to study more CFD.
I like your point about side outlets preventing crumbs blowing inside the exit, I hadn't considered that! What I like about the side outlets is it seems (at least on paper) to do the job of retaining the pearls, without being so complicated to machine as some of my other considerations.
What do you think about loading pearls in through the top inlet holes? It's so simple, I can't quite tell if that's brilliant or awful. On one hand I'm thinking, if they are packed in good enough, will they even align with the holes to fall out, or really move around, even if it was turned upside down? Some of these things come out quite different in real life, versus on paper
Potentially could be designed so they could only even be loaded through one hole with the appropriate diameter.
Appreciate EVERYONE chiming in and joining in the discussion!!
I am selfishly hoping for a device that does not compromise performance for anything. Including safety (within reason)
That’s the all glass smoothness! Wish I had a few coils on hand as I have a couple glass bodies.Shit man..........Mrs.arb is using a e43 and loving it so far.
She is very shy and not usually into anything "dangerous" but only had mild reservations about it........perhaps due to the diminutive size.
I was quite surprised to say the least.
I don't know, I'd love something like this, and I can get pretty spastic! Seriously I'd find a way to eject a hot bead into my lap, or something. Part of my condition. It's one of the reasons these kinds of coil designs have scared me a bit: seem like a good way to hurt myself. Which is unfortunate, because I think it is exactly the kind of vape I'd most like to use. I love my DiTanium, but I'd love something heavy hitting with an all-glass/jewel/ceramic airpath.his thread is going to fling hot balls across the room, but there are people who would find a way to do it.
Do you have any pics of the Flame powered vaporizer ? Is it something like a vapocane or gn0me ?Been playing with a Tafee Bowle a kind member has let me test out, needed a change of pace and pulled out my SCVW Mini last night, about 30s of torching to reach nirvana! So good I had to do another small bowl immediately after just to make sure. Anddddddddd out like a light before 8PM. In my opinion it's one of the stoniest signatures of any vaporizer I have tried.
Also, the SCVW has "diplomatic immunity" when it comes to "vape mail"
Just in case.
I don't have any updates right now on the desktop. The $xxxx laying around here in what I consider "unsellable" parts has, in some regards; killed my buzz. The quest for da best desk (top) vaporizer will go on, assuredly, but presently, my finances are pretty tied up with my main biz. In hindsight, I probably should have started selling the first InVerzion vaporizer that I posted on page one of this thread, to open the road up both ways. That would have made it easier to fund further R&D, with the preface that I've always been just a guy in an apartment on a passion project. That said, my estimations were fine until I switched over from boro to quartz, of which the cost to prototype and manufacture has been drastically higher, which I didn't really anticipate. Sure, I expected higher costs, but I'm talking many times over.
I think if I was really smart, I would have just sold ruby pearls to people to put in their current vapes lol.
Anyways, I'm not sure what even spawned this rant outside of excessive vapor intake lol. Not broke, just bent. The great desktop race shall go on, but it will take some "recalibration."
In the meantime, I might have to start designing artisan coffee cup attachments, or something.
