Firewood Vaporizer

[WhyWhyWhy?]

For size comparison. I really dig what mark has done with the X. Nice and compact.

Great photos! Please measure the length of the glass stem . I'm also waiting for my FwX to Europe and I'm thinking of pre-ordering BB6 or BB3 from Dynavap for it : BB6 stem

I’m not sure on the stem’s dimensions, but it is the exact same as used in FW 7.

Oh, so the stems that Mark has on sale should be suitable for him:

Anyone understand the decision to not utilize 21700 batteries in the FAT X? Could it be due to formfactor and as someone mentioned Marc wanting to keep it small?

Marc talked about this a bit back in the FW6 days:

I hadn't really thought about it and I think I'd be hesitant to consider it due to the larger size. I calculate a 21700 to be 47% larger volume than 18650 and they only have about 33% more capacity, so seems like lower energy density at this point.

I'd prefer 18650s for me in any case.

Yes and this is the exact stem my FW X came with.

Firewood 7 Dimpled Glass Cooling Tube (Smoke Gray)

This Dimpled Glass Cooling Tube can be used with the Firewood 7 Extra Cooling Mouthpiece to provide cooler vapor than the standard mouthpiece. Tube length is approx 3 inches (76mm), inner diameter is approx. 0.31 inches (7.9mm) and outer diameter is approx. 0.49 inches (12.5mm).

Hmm, might have been true when the FW 6 was being produced? But reading a bit online today and a 40-50% increase in power density seems to me a better battery even though the increased length he'd have to accomodate in the unit. To me it seems like the 21700 is way superior to 18650s, like who wouldn't want to have a longer runtime and be able to squeeze out one or more additional loads?

"The energy content per cell can be higher by ∼50% for 21700 compared to 18650. Therefore, for certain applications, less cells have to be built and used to deliver the same amount of energy."

I would prefer 21700 myself But to each their own!

Link to study

This study is from about 6 months before the quote above. And I've found that 18650s have only improved in the interim both in capacity and longevity. To me, the calculus is still the same. Better energy density and a smaller vape.

 

[florduh]

My only criticism of the design is "FAT" being emblazoned on the button lol. Which is why I'm fine with the 18650's. Can't have the FAT vape being any thicker.

 

[Bonesvapechi]

Looks like already the thing to carry out and about. Sadly my FAT X had been stuck in Indianapolis since 02/5

To me it's obvious that the 21700 have a higher energy density if the numbers are correct from the study. As you mentioned that the 18650 have gotten better the same goes for the 21700. I would like to have the higher density and wouldnt mind a marginally longer vape due to this, might even not need to carry an extra battery with you as I ALWAYS do with the firewood 9 let's agree to disagree @Grass Yes hehe.

Hahahaha good one Florduh, laughed my ass off! But the vape would one become longer and not thicker, as the 21700 only are longer but have the same diameter. This is apparently due to holsters for arms/flashlights not being able to fit in the holsters if thicker (dunno if this is correct, but what I read)

I thought the numbers were the dimensions with those batteries?
So 18650's are 18mm diameter and 65mm long and that would mean the diameter of the 21700 is 21mm?
Or am i wrong?
BTW: i really love how this FATX looks!
I kinda want one!!

This is not true. The numbers of these batteries are the dimensions. An 18650 is 18mm x 65mm. A 21700 is 21mm x 70mm. So a 21700 is both longer and thicker than an 18650.

Oops I was apparently wrong, dunno where I got that info from. Here's info from the same article I linked

"Figure 1. Size comparison of 18650 cells (h = 65mm, d = 18mm), 20700 cells (h = 70mm, d = 20mm), and 21700 cells (h = 70mm, d = 21mm). a) side view, 20700 cells are not shown since their side view is very similar to 21700 cells. b) Comparison of cell diameter, (b) not in scale with (a)."

 

[florduh]

I should've just said "bigger". If my vape says FAT on it, I support minimizing its overall size

As for the metal storage, if it's not made of metal, then what is it made of? I think it will be stainless steel..

As for the grooves, if they need to be made with air intakes, so that it is easier for hot air to go up into the free space (in the grooves), then enter the capsule and rush down to the mouthpiece, rather than going straight down between the walls of the ceramic and the capsule.

Yes, if you don't make grooves and just heat it up a lot, the result will be, but I'm afraid the middle of the capsule will remain uncooked...

I didn't say it wasn't made of metal, I suggested it likely didn't matter. And your theory as to how the grooves will help you is flawed. The cloud formed above the inlets will essentially be an eddy as the fluid follows the force acting on it. The fluid rushing through the inlets will go straight down and won't be able to grab all the vapour that has formed above the inlets.

I could argue with you about that. I think you didn't quite understand where I intended to make the grooves. Please note that the capsule can fit closely into the chamber, it will be easier for air flows to go up in the grooves and only then down to the exit. But if the capsule is not tightly located in the chamber, then, yes, no grooves will help.

A fluid flows according to the forces acting on it. What force is pulling it up and away from the suction at the bottom of the bowl? The grooves also won't help much if you hold the button to cook the bowl before inhaling, the ceramic above the inlets will do a far better job at heating the herb than the grooves can.

I think I heard that the mouthpiece doesnt retract on this version... maybe cos too small... is that right? Still want one.

I came to ask the same question - thanks! For those with one in hand, can you confirm the mouthpiece indeed isn't designed to retract? Based on the photos posted so far, it would appear not.

If so, this could honestly offer some interesting mouthpiece options. For example, on my FW7, I've always been hesitant to use a longer glass stem because I didn't want it to always stick out. But if it will anyway, then why not? Or I'm wondering if a short Mistvape Beaded glass stem (with a wood mouthpiece) might line up very nicely (?) Fingers crossed I get an X and get to test these myself

 

[PossumMD]

@MHL @rvarick Marc has stated the mouthpiece is non retractable.
