The Nomad From Morwood

@KeroZen , No problems here, communal discussion is important!

In case of a prolonged misfire, constant on with no airflow. There would be other things I'd worry about beyond the PEEK. Mainly burning out the coil, browning the wood body, and most of all, heating the 18650 cell or over draining.

And just so we're clear, there are two safety measures I took to make sure that doesn't happen. One, the button itself is difficult to accidentally depress, it's not what you might call a hair trigger, the throw is relatively long, and the spring pressure is enough to resist, say.. the pressure of your pocket.

But more importantly, there IS a hard OFF lock feature that breaks the circuit. It's built into the design of the connector bridge. When swiveled, and the locking screw slightly tightened with your finger, the bridge is locked into place. You physically can't swivel the bridge back into a position without breaking the device.

I would definitely encourage everyone to engage this safety when the vape is not in use, as it guarantees no misfire is possible.

Also keep in mind that the massive bronze bottom plate is a huge heat sink that has a fairly large contact area with the heater module. Any heat that travels back down the shell (which is thin SS, so not very good at transferring heat in the first place) is conducted into the bronze bottom plate. In my mind, this is an important safety feature and part of the reason I used a thick bottom plate. Non of this gets hot in use, but in case of a misfire, I think it will soak up a lot of the excess heat and channel it away from the more heat sensitive areas.

In case you are interested, here is the PEEK I used. This material isn't like a consumer-grade plastic, it needs to be made to very strict guidelines. This stuff is used in extreme vacuum (because of it's purity, high temp, low outgassing, etc..) and it's put into peoples bodies for medical implants etc.

But yes, there is definitely a stigma around plastics in general, and I think that alone is perhaps worth the change. The average consumer is not going to be knowledgeable in the nuances of PEEK, ha.

A. Blackwood, like a lot of the dense exotics, is relatively high in resin content. With thin-walled smoking pipes, I noticed the effect you're talking about, with a slight oozing of the resin on the outside of the wood. This was mostly a result of abuse, burning the pipe too hot. The resins can be wiped off, and in my experience, smells pleasant, just like it smells when you machine A. blackwood, sort of sweet candy like.

But, the insulator end of the Nomad HM does not reach temperatures anywhere near what would be required to do this. I've never noticed this effect here. Also, the part is so small that the actual resin content would most likely be negligible compared to a larger body of wood.

@szai , A very good point. In normal use, you're bound to have a few exhale events that blow a bit of vapor back down the stem into the heater module. I have soaked the heater end of my module in acetone a few times to clean it, but don't submerge the wood.

I have a feeling that A. Blackwood would be able to take being boiled and soaked in ISO, but the cracking risks increase with that sort of abuse.

hmmm... what to do...
FWIW I'm down with PEEK for deep cleaning options. I know you don't want to overwhelm people with options tho so I'll be perfectly happy either way!

@Dan Morrison ... Hmmmm what to do indeed!?

How hot might the high range heater get with say, use of concentrates? Apparently PEEK can withstand heat up to around 650F?

Your point regarding thorough cleaning of the heater has given me pause to reconsider the PEEK.

I think communal input is important on this "issue" as well, so maybe give this another couple days to be discussed here? I trust your knowledge immensely so please know that I will gladly defer to your call on this! :tup::tup::tup:

Many vapes & accessories. Always happy to help
I'd love to maintain wood where it's possible. Love Blackwood and I think this vape deserves to have it. :)
The thought of something plasticky (even high grade) in this piece of wooden art..hmm... Not my preferred option.
I won't carry my Nomad around where I need to deep clean it - it's not a travel vape in my book.
Anyway,I'd be more than happy to buy an additional PEEK, if it would help Dan and the crowd to have em both made for whatever scenario :)

So I've been doing some hard thinking on this. It seems that the main benefit of PEEK is the ability to deep clean it.

But where did this whole... you can't soak wood in alcohol thing come from?! I always felt like it was just fact, that it would dry out the wood...or..something. But looking into it deeper, I feel mislead.

Seems as though it would be completely fine, if not beneficial, to soak the african blackwood in alcohol. I've been doing some experiments and currently have a pot of very hot alcohol with test pieces soaking. I've recorded the dimensions to see if any change occurs.

One thing I noticed, is that the blackwood has slowly given up some of it's resins/oils/dyes.

This made me think about the practice of boiling briar wood blocks before using them to make tobacco smoking pipes. This was done to remove resins/oils, and make the wood more neutral.

So, perhaps there is something to all this.

Maybe A. Blackwood was the answer all along...

Will report back.

Probably because alcohols are used to dissolve cellular membranes and is such a commonly used solvent?

Well, seeing I paid quite some time ago, I'm not really missing the money now... So if in order to get even and keep your margin sufficient to sustain your living you need some more, I'd be willing to pay extra to have one of each rings (blackwood and PEEK)

Once I have the piece in hand, I'll surely have someone do a 3D model of it and have it printed in porcelain or another glazed ceramic. I'll share the files for those interested.

I'm confused as to why the ability to deep clean the heater is so important.

Is there no screen between the heater and the load?

No particulate should be getting into the heater in the first place, and in use inhalation should pull any tiny particulate right out again.

The nomad is already 10 steps ahead of the competition in this regard, in that the iHeat, RBT, logs, etc don't have removable heaters at all. But I'm not sure this is a feature anyone is clamoring for, since again the heater shouldn't really need to be cleaned.


I will echo sentiments that I'm more comfortable with wood than PEEK, mostly due to unfamiliarity but also just feel that wood goes better with the aesthetic of the Nomad.

Very strict drug laws in the states and abroad are the reason.

I wouldn't travel with most of those vapes myself.

While I don't negate the need for deep cleaning, you'd have to be crazy to travel with one of these. Once production is done, each Nomad is priceless.

I was in favor of PEEK, but if A. Blackwood can be cleaned then it makes no difference to me.

Just bought a Lotus because my VAS kicked my ass. It'll look beautiful next to my Nomad at least!

I think Dan plans on making these for some time hopefully. Besides what's the point of buying nice things if not too use them? Generally all international trip are going to cost much more than any vape.

If you want a strong dose of vas suppression the supreme v3 and i the upcoming v4 will do it for you!

You do quite a remarkle job on the button/inlet thingy!! They are spectacular. The blue coral eye is a looker . The one that looks like trichomes too . I've worked with abalone, mother-of-pearl and red coral for flat surfaced inlay , the way you bring tour pieces to a 3 dimensional dome like button is very stunning .

I truly understand both sides of travel with or not dilemma , it be a bummer to have it confiscated, and at the same time it is a vape meant to be enjoyed . I wouldn't know what to do myself but i do salute the ones who have the courage or cushion to pack and carry .

Well each is handmade with love and care, and eventually you won't be able to purchase one new. So while it's cheaper than a vacation & flight, eventually buying one won't be an option other than second-hand. So, personally, I wouldn't risk taking the Nomad on a flight to or from an illegal state/country because it's far too valuable to me, and the M fulfills my need for a travel vape--inexpensive and more importantly not valuable. :)

In regard to cleaning A. Blackwood, I came across an interesting fact about the buoyancy of AB, or lack thereof, in that it will not float in water. I would logically assume then, that AB will not easily be effected by many/most liquids due to AB's lack of porosity that in turn is demonstrated by its lack of buoyancy.

Well...that's my theory and I'm sticking to it...at least until the greater minds here prove me wrong! :myday:

The point, to be clear, is that cleaning the heating unit with water, or perhaps diluted alcohol, may not actually pose a deterioration concern with AB?

Or I could just send you the original CAD file. It'd be much more accurate.

But this part really wouldn't be a good candidate for making in a hard brittle material. The insulator needs to take some amount of deflection. It's constructed in a way that would definitely not work with a material close to the hardness of glass/ceramic. You could make it work with design changes to the heater module, but it would make the design less...clean.

Anyhow, results from the A. Blackwood experiments are in. As expected, it worked fine.

The heater module was boiled in alcohol. A lot of the resin/oil/dyes were removed from the wood, turning the alcohol black. The wood insulator was then dried out in the oven on med. The resulting wood was definitely more 'dry' looking, and less black, but still perfectly fine. Dimensions shrank about 0.003" as I suspected, but not enough to matter. After acclimating to ambient humidity of 50%, the insulator returned to original size.

Anyhow, should be fine. I think I'll go forward using hardwood for the insulator.

@Dan Morrison :tup: Simply amazing, brother! When my name comes up on the list, my only request is a burl wood of some sort. Everything else up to you! Really regret not getting on the list sooner!

edit: I agree with the others, produce/offer the PEEK as an option (if it's not cost prohibitive!)

@Dan Morrison may I have PEEK? I am allergic and A.blackwood seems less safe choice to me, especially in warm/hot part of airpath. I also prefer durability of PEEK. And you already made them, so we will have our beauties sooner :) at least those of us who opted for PEEK.


Yeah that's a good point. I have bad allergies too. I can barely smell anything ATM. I'd like two as well, if that's possible.

@Xelatsok , Sure! Makes things easier for me.

I'll offer PEEK as well, since I do have a bunch already made, it only makes sense. And IMO, it's the better material.

About PEEK, since there seems to be a lot of interest.

I have tested the PEEK in case of a misfire, but not only that I tested way way above the temperatures possible from the Nomad.

To do this, I heated the end of the heater module and center pin with a propane flame to achieve much higher temperatures than what would be possible with the heater alone.

The center pin is the only part that can carry heat down into the PEEK, the shell never gets more than warm.

This center pin will never reach temperatures near the continuous operating temperature of PEEK. BUT, if it does, the PEEK does not degrade or melt under extreme conditions.

At a center pin temperature of 500f at the heater end of the HM (again, way higher than what's possible with the heater alone), no effect on PEEK was observed.

Upon heating the end of the center pin to bright red hot (approx. 1500f), no effect on the PEEK was observed.

The point I am trying to make is that even if the heater end of the module, and center pin, reaches temperatures well above what's possible with the device, the heat that actually reaches the PEEK end of the HM is still below it's continuous operating temperature.

The oxides that form on stainless steel are a good indicator of the maximum temperature reached. Even with the heater end of the pin glowing red hot, the PEEK end of the center pin did not reach a temperature above 350f.

Now consider that the service temperature of PEEK (max. temp for continuous use) is 480f. The melting temp is 644f. And the onset of thermal degradation starts at 1067f.

When the parts were separated, the very fine texture left from the machining process was still perfectly intact on the inner surface of the center pin hole, evidence that no melting or degradation happened on the mating surface between the PEEK and the SS pin.

Also, side by side, the PEEK looks exactly the same as A. blackwood. I can't tell the difference.
