Origo 6000 alcohol oven, building/design one yourself?

[Franziska]

Thanks for the manual.

Learned the next thing.

Only one burner in the oven (thought there are 3 below, but it's actually 2 in the stove and one in the oven.)
That's good, as it's easier to find a way to manipulate the lid of the burner with a knob from the outside.
Finding a way to manipulate more burners at once is more complicated (But seems not to be needed!).

The burners seem like an upsized version of what you'd find on a fondue.
I'd think pressing the knob is disengaging the mechanism used to rotate the lid. The catch just holds the burner in place.
Press both together and you can take it out.

Temperature control seems simple as well, monitor the thermometer. Guess a simple one meant for sticking it into meat in a normal oven would do.

Once the burner is lit and the oven shut, you turn the knob which turns the lid over the burner and with it exposing more or less of the flame.

As kind of a parts list one should get:

*Ideally an Origo 3000 burner or similar
*Metal box or old small volume oven or even stainless microwave housing
*A partial cover for the burner
*Some sort of rod to manipulate the lid and catch
*A heat insulated knob
*If no old oven is reused a heat resistant glass for the front, some insulation and a heat resistant lamp fixture and some hinges for the door, some baking trays
*A rail to fix plates inside the oven
*A meat thermometer
*On a mono add some sort of gimbal

There are three Origo 6000's on eBay in the US right now, including a brand new never used one. Two on the west coast and one in NY. $1750 to $2000. Plus shipping.
It would not surprise me if there were a few to be had around Europe, too.
This doesn't answer your question about how to build your own. But it would put a complete working unit on your door step before the end of the month.

Thanks for looking that up.

Heck of a high price though. If a normal Butane/Propane oven can be bought for 300€ and the Origo used to be 700-800€.

For 2000$ I'm converting an old gas oven thank you.
Material cost, maybe 250€ or less.
Especially now that it's clear how the original one works.

Origo 6000 for sale in classified section $1,100... it won't last.

I have been kicking around some design ideas in my head for a 3000 (6000 minus the oven). Here are the "basic basics" I have come up with.

The "burners" (fuel canister) really are not complicate. It is a shallow metal can with some wicking material inside. Alcohol does not need pressure or much of any heat to vaporize (Pour some rubbing alcohol in a shallow dish. It will "evaporate" (turn to vapor) at room temperature within a few hours.) Light that small dish on fire and it will burn at a reasonable rate. Obviously once the burner "can" get warm, it will vaporize the alcohol faster which is good, because alcohol does not have a lot of BTUs. The top with the smaller hole concentrate to flame.

For the fuel canister, I would start with a quart paint can. Much too tall. Cut about 2"-4" out of the center of the sides. Cut 1" long tabs in the sides all the way around. Flex the tabs in and press the top portion on ! It will not be liquid tight, but I am sure you could find some type of high temperature adhesive that should make it liquid tight before the assembly.

From some reading about alcohol "backpacking" stoves, many things can be used for the wick. Cut rounds of fiberglass cloth and stack them in the can before assembly. Ceramic cloth insulation would be better.

This is easy so far, but I have not figured out how to do the hole in the lid so that the flame can be some what controlled and snuffed out.

The "box" is basically a 9x13 baking pan with very tall sides. Grates/pot holder are bent SS rod.


I think part of the problem with the Origo is that they last FOREVER ! Second issue is, with the cost of solar cells, chargers and inverters dropping every year, electric cooking (induction hot plate, microwave, etc) IS a viable option.

Say you have made your choice and settled for alcohol. You start hunting for a new or used Origo 6000 (which was the only true stainless reliable one on the market until recently).
Now you realize it's not made anymore and used ones are very few to none on the market too.

I was wondering if anyone considered building/re-engineering one along the same basic design.

It should not be too complicated and a crowd sourced design which gives the plans away for free would make something similar available again. Maybe even an improved version and focusing on a simple built method even by non metal specialist people and safety.
The plans would need to have a "don't do this at home and if you do anyway it it's completely at your own risk". Disclaimer on it ;-)

Esentially it's a stainless box with a drawer for the burners underneath.

The main issues to solve seem to be:

-Best way to control temperature
-Content of heat pods (Glass wool, stone wool, metal wool??)
-Insulation
-Air supply & exhaust
-Maybe adding a computer fan system to distribute the hot air inside could be added? Slowly blowing in a little bit of cool air from the outside through some sort of heat reflection baffles might work?

This: https://zenstoves.net/Stoves.htm might be a starting point for the burners. Or one uses burners of the alcohol stove Origo 3000 which I believe is still in production.

Just thinking out aloud, pondering the idea and wondered if someone might catch on to this....

It would be an easy project. These alcohol stoves are totally safe (except in the hands of a total libtard of course who could kill him/her self with a ballpoint pen!). These stoves give off only water vapor and carbon DIoxide ... N O T carbon MONoxide!
I have an Origo 3000 that has been going now for 19 yrs. It has rusted in the roung "pipe" where the flame comes up thru. That is an easy fix. If I cannot find a 2nd hand one, and I cannot get the part its an easy task to fabricate a couple.
This stove is simplicity in construction, VERY WELL DESIGNED. They could have made the flame cone part out of 400 series stainless for better corrosion resistance but I suppose that would have put the cost of stove up significantly.
If the designs are flying around I would like to see them, I am a bit of an Engineer myself.

You can still buy the heat pods, either Ebay or perhaps through Project Gaia. CleanCook makes them and the design has not changed. Origo stoves are out of production.



The computer fan will cook, but you can buy replacement convection oven fans, which extend in through the metal box.

Clean Cook. They are making the stoves. The problem is finding them at retail.

Products – Cleancook Sweden AB


Try Project Gaia. They are in the US. If enough people goad them, perhaps they will put some on Amazon, which would raise money for their project, increase volume which cuts costs, and make the product available at retail.
