My mini Trangia gas stove

[Tony]

This one been in my stove works for a while and as I am about to do some alpine bushwalking/snowshoe trips soon, I thought I finish it of ready for some field trials.

My aim has been to make a cold weather gas stove that is very resistant to windy conditions, fairly light, efficient and easy to setup and pack up.

The stove is a Kovea Supalite Ti with a pre-heat tube and a mounting plate added, the upper windshield bowl and the lower stand bowl are from two cut down 1.5 litre ally pots. The canister valve is from a cheap Chinese remote canister stove.

Though this is not the lightest setup, currently 396.4 grams, the initial tests look promising, and with some more development I can drop some of that weight a bit.

I am not that concerned with weight of this stove as reliability and efficiency in very cold conditions are more important.

This is a one liter pot solo version, I do have a larger 2 person 1.5 liter pot version nearly finished.

Impressive! Do you mind my asking of the total construction cost?

Hi Strider,

Probably around $110-130.

I paid around $60 for the stove (this is my summer stove)
Around $25 for the two pots that were cut up.
$30 for the cheap Chinese stove that I took the canister valve from.
The 1 liter pot cost $10.
The fuel line is some special high temp line I got many years ago.
The other bits pieces are from the scrap bins at my work.

What an awesome stove. Nice work!

I used this stove system in the field on the weekend, we camped near Mt Kelly at an elevation of 1530 meters, the evening temp was around -5C, the morning temp was recorded at -10C.

For the first time in the field the stove worked very well, I could not be happier, for the evening meal at -5C the stove started up and cooked my meal with no problems at all, in the morning at -10C it took a minute to warm up and get going properly but at these low temps this is expected. I ended up boiling water for three other walkers who did not have a stove or stoves would not perform in the cold, one person who I boiled water for his pot had around 800ml of water which was half ice, all up I used 49 grams of gas.

This stove system is looking very promising.
