Dynavap VapCap

[DirtyD]

Just bought a Blackwood nonavong, should be here in a few days. What's a good cheap bubbler link? What will fit my nona's seal. I know its 14 mm to seal a joint. Pretend I'm 5 . Dont know about all this 14. 19 mm shit.and please, post a link of that bubbler that fits new nonavong real, real good. Thanks! - Dirty D : glass noob

Google FC-188 dhgate

If we link, it gets removed

Edit to add: Not the FC-187 which is the 18mm version.

Check the "Cheap high quality bubblers" thread in the "Glass" subforum, and read/gloss over the last 10-15 pages (maybe even the last 30?). Should be easy reading as you already know you want a cheap and 14mm joint. I mostly look at the links and pictures to help determine what I want. Lots of good discussion in there...

Hi @mccringleberry , did you covered the carb hole when hitting with the bong? its important to cover the carb hole to get dense cloud. You may use little rolling paper to cover that if you found its impossible to cover it with your finger when the VonG go in the bong stem too deep. Enjoy~

Absolutely, and yes I do keep the carb covered when drawing with my bong, exactly as I do when pulling direct and it makes no difference. Its still impossible for me to get thick vapor w/ a WP because im not mouthpulling, which is what kickstarts the thick vapor production IME. And I feel like I would have to get a bigger torch and up my chamber size and consume more bud than I want to just for the sake of getting big clouds thru a waterpiece. Honestly, I get so much satisfaction from using the woody direct that I amost never use my bong anyway.

Thanks alot. Perfect! Cheers Sir, D.

My thoughts regarding the OMNI moving condenser.

Covering the carb hole on an OMNI model is actually cancelling out everything
the OMNI model has to offer.
And that is a really smooth and mellow vapor.

Actually ,to take things to the extreme side ( my fav side ) me,myself and I ,
we all consider that all the VapCaps work amazingly-awesomly -astonishingly great WITHOUT a carb hole.
At least for stoners with not so sensitive respiratory system.



Except the OMNI.
The latter is designed to operate WITH a carb hole .

And actually there's a "golden spot" regarding the depth
adjustment of the condenser inside the inner tube of the tip.

Too far out of the tip ,the pressure difference won't generate much force to pull vapor from the chamber ;and then you cover the carb hole ,to take a decent toke.So,you have paid double the price ,just to get the same operation with a standard condenser or am I missing something else here ?

( No covering of the carb hole AT ALL with the OMNI models.
They are designed to operate based on the Bernulli effect.
Thus they need -no matter what- an air inlet
far larger than the gap between the cap and the tip. )

On the other side ,too far into the tip and the velocity difference is minimised.
Thus cancelling somewhat the Bernulli effect.
Then one quick solution would have been a larger air inlet ,thus a bigger diameter carb hole .

So,no too far out ,not too far in ,with the carb hole -at all times- wide open.
I bet ya ,that somewhere there's a "golden spot" that will allow -with the carb fully open -
for a golden equilibrium between mellow/gentle and dense/thick vapor.

With an ordinary VapCap (standard condenser ) things are more straightforward.

1) Carb closed /carbless : THICK /DENSE vapor but HARSH /HOT .
2) CArb fully open : MELLOW/GENTLE vapor but THIN/DILUTE .

and

3) Feathering the carb : Dunno actually if it works ,
but after some practice maybe you can try and play the flute or something similar .
Maybe you'll be sounding like a real virtuoso.


That's why double the price on the OMNI.
Cause it can do what the rest can't really .

Cheers.

Oh Lord! Could I please choose at least 3 Vapcaps when everything else has to go and shit hits the fan? Would already be hard enough to decide!

No contest. For me, if I could only have one Vapcap, it's an Omni all the way, with maybe my Copper Stoned stem.

Another element of the Omni compared to all others is the effect of the threaded condenser/mp on durability. The condenser in all other Vapcaps floats inside the body or stem secured by x-rings. The Omni condenser is much more solid and dense than the regular condensers, fitting tight inside the midsection and adds a robustness to its durability. The Omni condenser adds support to the body. This may be why the Omni can withstand being run over repeatedly by an SUV.

 

[Dynavaper]

It will, of course, be an Omni. No contest, too. But with which stem/body? I would not be able to choose only one... Damn, even the thought scares me!

If we're talking an everything goes to shit, doomsday scenario, I would choose a metal body or stem. Likely titanium because, who knows, weight may be a factor, an Honest lighter, a case of good quality butane and a nice solar heater.

Oh, yeah. And a pound or two in your stash. You can't never be too prepared.

You've just gave me an idea ...

Loving the thermal properties of titanium ...
Especially the low thermal conductance...
And the extra thermal isolation the anodic TiO2 layer has to offer ...
CONDENSERLESS stems !

A 10 mm Dia Ti rod is needed .
and then a real metal-working lathe .



Have to try that !


Cheers.

 

[Dynavaper]

But you won't have adjustable airflow then? The idea itself is nice, anyway.

I'm on the carbless boat ,dear brother ,remember?
No adjustable airflow for me .Only for high resistance on the incoming air,I'm after .

And less parts involved at my VapCaps .
(Minus one condenser and two x-rings ? Sounds nice ! )

One stem ,one tip with it's four o-rings and the cap .
Effective Simplicity.

Talkin' about maximal minimalism ...

 

[Dynavaper]

Me and remembering things... Lord of the Fail.

It's not that your signature could have been a hint for my faulty brain... No, no. That would have been too easy.

Velocity vs pressure.Large diameter (stem) vs small diameter (condenser) .
Once you draw ,the air enters through the carbhole into the stem .
Then it takes a sudden 180° turn and enters the condenser.
Since the incoming air moves from a large diameter into a smaller diameter tube ,it's velocity increases.That creates a pressure difference ,exactly where the condenser tube end is located
inside or near the tip.That pressure difference "pulls" vapor from inside the tip into the condenser.The turbulance created by the 180° turn ,
makes the air velocity difference stem versus condenser ) even greater,
thus increasing the pressure difference ,thus forces more vapor to be mixed with the incoming air.

hm, i bitched about that a while ago , Bernoulli sounds fancy but it's just an equation that can be applied on many things...
Btw the old fluid mechanics joke is: never talk about Bernoulli without mentioning his girlfriend Continuity or u can start recalculating
The standard bernoulli equation only applies for fluids without thermodynamic influence eg a unheated vapcap. So it's needed to add the thermal equation for ideal gas into the mix, but that equation changes with different types of state changes...
If u got all that down for enough points in the system, then it's still only a static equation - the real fun begins with making it dynamic...
Well to really know what's going on it takes CFD simulations, and measurements to verify the simulation. I would love to see a vapcap CFD, but i somehow doubt that there is one....

Yes,you are right !

Still,you do know about another joke regarding a horse breeder and his dying horses.
Nobody could give even an answer to what's wrong with the horses,let alone to find a cure.
Nor the vet,nor the doctor ,nor the magician,nor the priest....
And then the astrophysicist found the solution !
But it was only about ideal quantum horses in absolute vacuum and at -273°C ,
in zero gravity conditions.

Yes indeed,there are far more complex phenomena taking place ,but the whole general concept
is based uppon the Bernulli principle.
The exact actual phenomena that take place ,are not easy to speculate ,let alone to calculate.
Yes ,I've thought about a CFD myself also...
But then a high resolution thermal camera,is much easier for me to find.
I'll give it a shot ,taking a vid ,as soon as I'll have the chance to borrow that camera .

Cheers.

i doubt that there is much to see with metal bodys they shield radiation pretty good, the glass version will be better for that - but u could add a little plastic straw at the mouthpiece end to see at least the exit temperature while pulling

Actually glass makes things invisible to a thermal camera ....

From the other hand ,with metals -due to their relatively high emissivity- one can never be certain
about the results.
They tend to to give false readings of their actual temperature and thus tend to skew the thermal image.

Hi there,
I read about this device but never came to realise its potential.
I own a Mighty, Hopper and Solo1.

Want to try microdosing ans want a small reliable unit.
dynavap M should get a try

One thing though.
Is it okay for CBD strain use?
I really want the CBD goodies.

Mighty and solo can handle that.
can the dynavap aswell ?

thanks folks

 

[Dynavaper]

can the dynavap aswell ?

I see absolutely no reason why it should not. Or is it about the exact temperature control?

You're going to love the Vapcap!

I vape Cannatonic, Harlequin, Remedy and other high CBD strains regularly in the Vapcap. The Vapcap can handle any strain in any form, such as dry buds, hash or concentrates like shatter, rosin and wax.

For buds, I just pop an unground nug in the herb chamber, place the temperature indicating cap on top and heat to the click. Toke until you hear the cooling click then heat again. No need to grind. No need to stir. Super efficient. Easy peasy.

For hash, I place a thin slice to the chamber for hard hash. Soft hash can be pinched off and flattened into a small thin pancake, then placed into the herb chamber. Hash takes a bit more heat so I go a second or so past the click. Toke and repeat.

For concentrates, I add a modified concentrate pad to the chamber and place the concentrate on top. Here is some info on how I fashion a concentrate pad for my Vapcap.

[Mr.Sifter]

amazing.
i don not care about exact temps.
must get hot enough for full 'noids extraction though

the M ist the right joice? for a vapcap newbie who is not too rich.

 

[Dynavaper]

It absolutely is. Especially if you're on a budget. The M keeps the temperature a bit longer because the stainless steel takes more time to cool down than the titanium. You cannot go wrong with this device at that price! You can still use the SS tip on the other stems and bodies if you ever decide that you love the other materials more that pure SS all over the place.

The Vapcaps are really good when it comes to full efficient extraction. A small amount of material will take you quite far!

 

[Mr.Sifter]

would be great to load it with a decent hash and take it along as "your special cigarette".
How many draws could one get out of a pinch of hash ?
ok this is hard to answer.

eeeehm, a herb load lasts 3-5 hits in the VC M.
how about softish hash ?
