My first woodgas stove!

I love the post, super great info! I'd like to get my hands on one of these or make one or somethin someday it's sweet!!!
 
okay, much more information for this rock dweller. the final pictures really made it!

thanks! that looks like it rocks...

for some reason, wood gas conflates to wood alcohol gas...

pyrolysis is fun! and dangerous! there's a series of videos show how tyres can explode if you get them hot (esp with arc welding), and they keep getting hot, and hours later, can explode. or they can do it in five minutes. scary.

Explosivo!
 
Anything you would change or do differently? I'm going to use your info and make one. (since I'm apparently not going to win that one)

Make the holes smaller than you think you need them. You can enlarge them later if you need to, so go small at first.

Use good cobalt drill bits and a drill press that is very solid if you have access. You can hand drill them, but they will be uneven, and they will piss you off. Use a center punch. Keep it oiled or pour water on it to help it keep from burning. It stinks. For bigger holes, like say larger than 1/4", start smaller then work up, a unibit or step bit is very, very useful for the outer chamber.

In the outer chamber, I think you want the holes to end just below the level of the bottom of your inner chamber, maybe even 1/8"-1/4" lower. Do not put them at the very bottom though. You want a little space up from the ground too.

Go slow. If you cut the top hole in the outer chamber with a dremel, be prepared to burn through a ton of those crappy cutting disks. Might want to try to get a diamond cutting bit, those are awesome.

Be prepared for how heavy it will be. The outer chamber is super heavy duty, so while it will last, it weighs a ton. So does the inner one.

If you have access, a Bain Marie pot is a good substitute for the outer, provided it meets the measurement requirements. They are still pretty heavy duty most of the time, but not nearly as bad as the thing I used. I think the 2 quart container I used ended up being around 4 7/8" on the inside. If you have any questions, feel free to shoot me a message.
 
Very cool post Derek. The gratuitous Becker pic really did it for me! LOL

I only have one complaint though. I saw where you said you use Solid Works for your design software. Well, my GW (Gorgeous Wife) has worked for UGS, the company that makes Solid Edge, for the last 12 years. Works is their #1 competitor. So, since Edge puts food on the table and Beckers on the belts and in the backpacks over here, please switch up at your earliest convenience!

Otherwise, awesome how-to post! LOL

A bump for no other reason than this just being cool, and cause I was thinking about making one again :D ;)
 
Very cool.

I need to make one like this. can you pm me links to were you got the pieces. No bed bath and beyonds near me.

Thanks

Jeremy
 
Ive been intrigued by this ever since I first found this post.
Gonna have to make a go of this once the new year begins.
Nice work man!
 
I know this is an old post, but I happened upon it while surfing, and have alot of experience with woodgas stoves. Im with one of the other members who mentioned the one quart paint can/ progresso soup can woodgas stove. I was actually making these and selling them locally here in Oregon on craigslist. I also make a pot stand/ fuel feeder out of a chopped chicken can. (They are a little taller than a tuna can and nestle in the bottom.) Your design with stainless steel seems optimal to super heat the gasses in the outer chamber and make them more combustible. My design uses thin walled metal cans that can lose too much heat in colder/ damper conditions. (It is Oregon after all.) The only thing I dont like about it is it doesnt look like it will nestle with a cook set, mine fit in the larger coleman cookset you can get at walmart. Also spot on with the larger/ smaller holes and using the wind as a baffle/flue. Mine are drilled only halfway around the bottom, and I use the wind to direct flow. Also, try sourcing your materials at 2nd hand/ goodwills. I have created numerous cookset/ stoves out of stainless stuff Ive gotten for pennies. Keep up the good work and be safe.
 
waitaminute... you MADE that??

Dude.
Are you offering 85%, 100%, and 115% scale versions yet?

Good lord it has been awhile. Not sure if you are referring to mine when you mention it doesn't look like it will nest with a cookset, but the coleman aluminum set you get at walmart fits inside this thing perfectly, all pieces. I might dig it out and get some pics of all that this afternoon. I never planned on making anymore as I have since switched to the ikea twig burner setup or my snow peak litemax.
 
Now there's an idea. Maybe once this place decides to have some normal weather on a weekend when I have time I can make that happen.
 
Hi Derekh, yeah I was talking about your stainless steel version. Couldnt tell from the picks the dimensions. It looked quite big. Heres a link to a set on ebay that is my exact setup, only my pot stand is a little different.

I also have one of those Ikea utensil holders (another goodwill find. $1.99) but found it eats fuel and I couldnt fab a pot stand I was happy with. This season Im gonna try out a US MIL canteen cup, homemade stove and pop can penny stove set up. The stove was made from another canteen cup, so I can multi fuel it up. Ide like to see how your whole system fits together ( Im big on the cook set and stove/ fuel all fitting together) Well, happy trails and be safe out there.
 
This is awesome. That's really nice Derek. Good job. I'm not as mechanically inclined but I see things like this and I wish I were.
