Discontinued The Okin by D.M. Pipes

°k

The sound of vapor
The Okin is a piece of art as much as it is a functional device. If Dan feels that screws are a necessary part of his work, it's not for us to tell him to do otherwise. In my opinion, those who have fears of lead in the brass screws would probably recoil in horror at the idea of inhaling vapour produced by a charcoal ember. I have no concerns whatsoever and like the screws.
I for my part like the band for its look and the screws for their practicality but it's irrelevant now anyway.
On a different note, I don't remember the discussion about the outcome of bamboo coal burning being over (stop me if I'm wrong), @Dan Morrison do you plan on having a lab test that for toxicity?

I like the look of the screws and have no fear of them.

Hahaha, I don't know why, but I imagine you standing in a crowd of people who had just witnessed the landing of an alien spacecraft... and everyone gasps in horror as the new species, giant brass screws, start shuffling out... and then you yell, as a warm welcome to our new friends, "I LIKE THE LOOK OF THE SCREWS AND HAVE NO FEAR OF THEM!"

No plans for lab tests. From my research I don't find it necessary.

Bamboo charcoal has a long history of use as an ingredient in baking. It's also used as a filter media for water and air.

The reaction that happens when charcoal burns is well known. The byproducts of the reaction are mostly CO2 if the ember is fed enough oxygen to support that reaction. If the ember is smothered, or exposed to a low oxygen environment, such as what you might find in a BBQ or hookah, it may not have enough oxygen to support the formation of CO2 and instead creates CO, carbon monoxide.

Since the ember is at all times being fed a constant supply of air during use, the vigorous rate of burn and colour of the ember indicate that the reaction is nearly complete, forming mostly CO2.

Since we're not vaporizing in a lab setting, in a chamber filled with pure oxygen, we can assume that some carbon monoxide is formed during the burning of the charcoal. Though, it should be assumed that this amount is very minimal, especially considering both the size of the ember and the duration of use.

The question of whether or not you're okay with this is up to you, but personally I am not worried.

functionally it would be like using a hookah, and we've been doing that as a species for a long time. I don't know anything about charcoal, but I would assume the bamboo charcoal would be better than the smelly stuff I buy for my hookah.

Here's the newest prototype. I made some changes to the internals. This is just a rough model that I will be keeping, as it's missing the second set of brass screws that I will be adding to the final design.

I didn't bother putting a patina on the metal tip, but now that I see it finished, I really like the dull silver finish... Perhaps I will just play around with different patinas with each batch of vaporizers.

As you can see, I've used red sewing thread for my "o-rings". I switched out the metal screen for a cotton screen. This lets you use whatever cotton fabric you like, customizing the mesh size without having to order new screens. It also has better contact with the walls of the chamber and allows for a larger filter area opposed to fitting a metal screen on the inside diameter.

You can plunge the filter all the way into the chamber, right up into the vaporization zone. So you could experiment with coating the cotton filter with concentrates.

Also, I mentioned that it would be neat to customize the stems with paint or drawings of some sort... here's an idea of what that might look like with some painted stripes!

How easy is it to change the cotton screen? My concern is that it will clog and be harder to clean than a metal screen. I like the concept but it has to be workable.

Herb goes infront of the cotton screen. You just drop the herb into the metal tip, connect the two halves and you're ready to go.

The screen is very easy to replace, just unwind the string, place a new piece of cotton fabric over the airway, leaving lots of excess to hold the fabric tight. Then tie it on with new thread, the thread presses the fabric down into a tiny groove, so that it wont slip off in use. then cut away the excess with a razor blade.

It seems complicated when i type it out, but its really not that hard, ill be posting detailed intructions.

You could also use the same method to tie on a metal screen, but its much more difficult to manage.

I only like using a device if its convenient, i don't want to fiddle around with stuff when I'm in the vape mood... so we will see how long this cotton filter lasts in use.

The problem I encountered with the metal screen is that it had to be fit into the inside diameter of the tube, this meant the walls of the tube had to be thicker to accomodate the groove for the screen, and so the airway was smaller....and the screens surface area was smaller. This small screen clogged when used with finely ground herbs. I switched it out for a metal screen that was the same diameter as the internal walls of the metal chamber, and the clogging issue was completely gone, and the airflow was increased. But in that design, I had to remove and then re-insert the metal screen into the chamber with each load, very annoying.

With the fabric design, the fabric is so thin that I dont need to cut a deep groove on the outside diameter, I could make the airway larger, and taper it out to the filter to acheive maximum surface area.

The increased airway, and the "feel" of a very fine fabric filter felt better to me.

It will eventually clog with oil, I imagine, but the most important part is that it doesnt clog in use, and so far it doesnt seem to.

Also, i like the idea of it being replaced with just about any thin cotton fabric you have on hand, or even coffee filter, tea bag material, silk fabrics, etc...

You could even pinch the fabric up into a point, so you have a sort of inverted cone filter... and dab concentrates on the pointed tip..maybe... I dont know if that would work, but in my head it does.

Anyhow, still a learning experience, so far I like this design the best, but we will see how it changes.. Always moving forward! By the time this gets to market it will already be version 4.0, hahah.

Edit: @stickstones , The glass chamber idea was abandoned long ago. I like the concept, but I went with a metal chamber for various reasons that I am sure made a lot of sense at the time, haha.

Edit2: For those a bit confused about how the chamber works, here is an image of the metal screen at the tip of the chamber. This screen remains stationary pretty much all the time, unless you want to move it further away from the ember for lower temperature vaporizing. When you press the two halves of the vaporizer together, the herbs are sandwiched between this metal screen and the cotton filter. The further you push the stem into the chamber, the tighter you will pack your herbs. So you could make the chamber size 1mm deep if you wanted to, to sandwich a thin puck of powdered herbs.

Nice. I get a vaguely Native American vibe from the Okin with those color stripes. And I really like how the new design keeps the mouthpiece away from whatever surface the Okin is resting on.

wouldnt it be better to place one of this vapor stones similar to Health Stone Glass for concentrates?

So I just read through this entire thread today...I'm beyond excited to buy this once it's available. Take my $$$$$$$$ ahahahahahahahahahahahahahh!!!!!!! :D

Seriously through, You're impressive, Dan, and I have a feeling your design will be a huge success.

P.S. I hate smoking, and have never enjoyed using a pipe...but I would marry some of the ones I saw over at your blog. Wow! Probably too early to ask for that mushroom one as a vape, eh?

Here's a quick video showing the loading and charcoal burn. I wish the shot was longer, but the vaporist featured in the video started drooling all over the table because they had to maintain exhaling while facing down, hahaha. In any case, it's a decent teaser. Please refrain from sharing outside of the forum, thanks!

Thank you!

And, I often think about doing a vaporizer in the mushroom-pipe style... I think it would be so neat! I will definitely be making some one of a kind bamboo charcoal powered vaporizers in the future. So many possibilities.

I need this in my life! Haha! That was some thick vapor! Is there a way to determine how deep to insert the mouthpiece into the vape chamber? Just go by feel? Thanks for the vid. Definitely a tease!:love::science::drool:

You just eye ball it really, works fine like that. I am still on the fence about adding coloured bands around the stem as a visual depth scale...

Great looking clouds! Judging by your video, it very much looks akin to using a cigar, which I dig :rockon:

Thanks! The cigar feel was something that I had originally had in mind when I was first thinking about making a vaporizer, so it's great to know that it shows in the end product!

There is just something cool or classy about a cigar/cigarette. I suppose that view is diminishing now that we society is shifting away from smoking tobacco, but what are the future western movie characters going to have in their mouths?! Certainly not a plastic looking stick with blue LED on the tip..... or maybe they are, who knows! haha.

I am pumped about this little guy.
Definitely a "glass of bourbon" type of vape...at least for me. Puff on this beauty in front of the fire...on the porch at night...oh yes, it will be a divine experience im sure. Flavor has got to be something unique and special. Especially with tasty tasty shatter...mmmmmmm
