AWESOME!!!!!

[vitalikxxxxx123]

the best



[ninjabob52]

I made a replica of this one by guns4toys dimensions, it works just the same! thanks for the backpack stove!

[WayneSadler]

That's a great smooth burn ... I sort of had it with my though it was a little windy, it seems there was not enough draw, & yet it all burn to ash the only way I was able to see the burn through the jets like in yours was when I put new wood on and had to blow to get it to catch. Any pointers welcome, I have photo's of the making it that helps many thanks wayne

[guns4toys]

@WayneSadler

Your right, it sounds like you need more draft. You can pull more draft by adding a can type pot stand. With taller cans pulling more draft. Are you using dry hardwoods or random forest debris? In smaller sized woodgas stoves it's important to use dry hardwoods to maintain the high temperatures needed to keep the woodgas process going. Larger woodgas stoves are more flexible about the fuel wood used. Also don't pack the fuel to tightly, it needs air flow through the fuel.

[marcustya88]

so this is an updraft gasifier right?

[guns4toys]

@marcustya88

I think they call this the inverted downdraft principle. But yeah it's an updraft gasifier.

[pongoid]

@marcustya88-technically it is a coaxial downdraft gasifier. An updraft gasifier would use forced air from underneath, or function like a Rocket Stove.

Are you sure that music isn't from Karate Kid?? haha. Thanks for the vid.. Best wood gas stove i have seen.

[jntroisi]

That works incredibly. Great job!

[caboflyguy]

This is what happens when you trap a bunch of alcohol under the center cap. Nice effects!

[guns4toys]

@caboflyguy

A bunch of trapped alcohol would burn blue, but you already knew that.

Good luck with your woodgas generator project.

[future2501]

beautiful

[mechreports1]

dude you do realise that you could sell these for good money right? cos i wud buy one!

[Coaljet]

Perfect music to watch this simple, yet enchanting woodgas flame by. An example of how simplicity -- simple technology in this case -- equals beauty.

[boatmaker2004]

YOUR VIDEOS ARE ALWAYS GREAT/THANKS

[terrydodson58]

Great looking stove. Do you ever sell them on ebay?

[guns4toys]

Hello terrydodson58,

I just make a few for fun and haven't really considered selling them. There is a gentleman from Canada named Fritz Handel from F. H. Enterprises who sell one of best small Wood Gas Stoves I've ever seen and it is called the Bushbuddy.

[Hopingtosurvive]

I made a wood gas stove out of a 1qt. paint can and used a 1 pt. paint can for the burn chamber. Using wood pellets, it will burn for right at one hour. These stoves are wonderful. Thanks for your info guns4toys.

[chevkoch]

Fantastic job. I'm about to build a small one like that which I can take with me backpacking. Thanks for the inspiration and info. Beautiful music too.

[fernandesilyt]

What's the size of  thise cans?

[guns4toys]

The outer can is a 15oz Ranch Style Beans can and the inter can is a 6oz Texsun Pink Grapefruit Juice can.

[wgrube]

Great! I also made a natural draft gas stove that worked. Soon I'l be posting a video. I hope we can exxchange some ideas about the different designs.

[WorldStove]

It is incredible how small you made it and still got that magic flame to work. 5/5 only because youtube won't let me give you a 7/5 or more

[Carlsarv]

Wow, im amazed that the flames can be so controlled, and it seems like the flames are comping from the air inlets and not from the wood, quite confusing and very intresting.

[morningstomper123]

The flames are comming from those holes and not the wood. The combustion chamber converts the wood into wood gas, and the gas is what burns.

[benjamindees]

The wood burning in the middle is Oxygen-starved, undergoing partial combustion and pyrolysis. The wood gas (CO, H2, methane, tars, etc) produced goes straight up and out of the can.

The "air inlets" provide additional (pre-heated) Oxygen for complete combustion of the wood gas, so the flames appear to come from the air inlets.

It's like burning Oxygen in a wood-gas-rich atmosphere. This is the opposite of the burner you have on your stove, which burns gas in an Oxygen-rich atmosphere.

[Carlsarv]

Thanks, great answer!

[cdltpx]

What a flame that was a nice flame I might but one of the commercially avaliable units but they are pricy for a pot with a motorfan. If I can get a pressure cooker for under $50 why cant they produce a woodgas stove for about the same. True we can build our own and I probably will give building one another try I have a solar panel and can locate come computer fans my only mistake was placing the fan too close to combustion and it melted. Bet if i build a tunnel around the fan insert location....

[hwardoyo]

Dear guns4toys,

This is Awesome.. I'm planning to build one.

[darek512]

Is that producting charcoal ?

[jalfrado]

Great job on all of your different designs. I was very impressed with the micro mini and decided to build one. I found that if you take the bottom out of the inner can and replace it with 1/4 inch hardware cloth it allows for a longer burn without the vents getting clogged. I also put a feed hole in the potstand so that you could boil 2 cups of water and continue that boil as long as you want. Also, if you take a heinepot and cut off the some of the top rings the micro mini fits inside of it.

[aa112211]

That is actually what I was thinking (I have not made one yet). I have a question though: How did you attach the mesh? When my friend and I built a prototype, we also included a feedhole so that you can burn a prolonged fire. The biggest thing I will change is to make the stove a gasifier.

Great job, that stove works great.

[jalfrado]

I cut out a square piece of hardware cloth (1/4 inch) and slowly cut pieces off to shape it to the bottom of the can. The way I attached it was by leaving four stray wires on the mesh that could be wrapped around and into the vent holes on the bottom sides of the inner can.

[divaraid]

5 stars again - very stable flow for a really nice flame. Have you done any experimenting with forced convection?

[guns4toys]

Hi divaraid,

Thanks for viewing and commenting.

I have not tried any forced air yet. I am trying stay away from using any electric power. But I have been working with chimneys and stove pipes to pull a natural draft for a similar effect. By directing the super heated flue gases up the sides of a pot or kettle to greatly enhance the efficiency of heat exchange. The same idea that the Swiss Mess Kit uses.

[guns4toys]

Hey pleabargain,

Yeah this was kind of a homage to the flame video! Because it is the smallest stove I've built that still held enough fuel to be useful and had a good clean burning gas flame. Watch my "guns4toys Homemade Wood Gas Stove Configurations" video to get an idea on how to build one and what tools you will need.

[benniblueyes]

Stupendo!

Non ci sono parole... ;-)

[guns4toys]

Grazie benniblueyes!

[DrChrisBiomed]

What's the burn time?

[guns4toys]

Hello DrChrisBiomed

Thanks for commenting.

With Mesquite or Hickory wood I've been getting about 14 to 16 min. burn time.

[DrChrisBiomed]

That flame was fantastic!

[Scytheon3]

plz plz plz plz plz show me how to make one

[guns4toys]

Hi Scytheon3,

If you watch my "guns4toys Homemade Wood Gas Stove Configurations" video you will see how they are built. It is very easy!

[godoter]

excellent *****

[impazzitoinvolo]

Good! Very Nice flame! What are the dimension od the cans?

Bye and congratulations.
