My UL Cooking Set

do you have more information on how the stove was made. How does it vaporize the fuel?
Michael

Between the pot stand (inner can / cut down deo spray, bottom partly removed.I chose this can beause it fits the bottom of the pot-can perfectly) and the outer can (coke) is a double layer of glasfibre/ Kevelar wick as it is used for fire twirling equipment. That wick soaks up the fuel. You light the wick and it burns a bit like a candle. Also the inner and outer can heat up and help evaporate the alcohol. A full filled catstove couldn't quite boil the 700ml and I had to refill. With 2/3 of the amount of fuel this stove easily boils the 700ml in my pot-can and burns for another 2-4 minutes. I think the reason for that is that the catstove's fuel boils and that is uneconomical. Yes it burns strongly, but there is just so much energy transferred to a tall can at any given moment, and in the catstove a lot of that energy was wasted, especially with a light breeze when all the flames accumulate on one side.
The "ring of fire" in this stove is compared to that very stable and burns all the way around, transferring the heat evenly. It is a tad heavier, but after 1-2 cuppas the weight is saved in fuel. Just the facts that it is spill prove is worth the extra few grams to me. Knocking it over and having a big puddle of burning alcohol was always my biggest fear with all other alcohol stoves I build before.

So you have a skinny can inside of the coke can. are there any ports at the bottom of the skinny can to allow the fuel to go under or does it just seep under due to not being sealed?

also do you seal the wick inside with anything or is it all just sitting in there.

looks really nice and if i could find some of that wick stuff it would be a fun build

Yes the inner /skinny can is just pushed in and is held there by the wick. It is a close fit. No ports or anything, it's not sealed.
Make sure you keep the wick about 1mm under the edge of the outer / bigger can, that makes filling/ priming easier.

If I can't find kevlar wick would normal Tiki torch or lamp wick work? i think that is mostly cotton. I have no idea where i could find poi stuff locally.

Give it a go, can't see why not. I payed a couple of dollars for the wick, I needed not much, 1" maybe. I used 2' widht and foldet it along the centreline to doubble it up.

Yea.. 1" deep in the can. i figure if it works and holds up then my brother would make one too.. he uses pepsi/penny can stove all the time so he might like this design.

Holger,

Thanks for sharing your UL cooking set.

I am keen to try that stove design. Can I ask where you purchased the wick material from?

Regards,
Michael.
