Yeah, have you actually tried to make his 2012 models? Way too much work, and his potstands are an ever present (if minimal) danger if you fall onto them.
Zenstoves.net , and simpler soda can stoves and marine grade denatured alcohol, are an easier bet, and easier to replace.
As to the origin poster, the finished used cans are extremely useful for making alcohol stoves.
2012 models... you mean the ones with the tubes? Yeah. Didn’t really work out too well. JB Weld smells REALLY bad when it burns. And that smell lingers.
I use msr whisperlight (white gas) and msr rocket pocket (iso-propane). Rocket pocket is super quick and easy, but the spent fuel canister is a waste. Whisperlight not as easy but fuel is refillable. The internationale model will take anything, whitegas, gasoline, I thnk the latest will even take an iso-propane canister.
The extreme light weight of the alcohol stove is appealing. My builds are nowhere near as good as this Tetkoba guy.... yet. The older I get the more I like ultra light.
