Last summer i found a new stainless steel flask in a charity shop for £2 , and set about turning it into a hobo stove . i have only now got round to trying it out as it has been hiding at the back of the shed since i made it .
So here is a step by step guide of making it .
Starting with the flask body i cut through both wall of the flask leaving me with two containers. For this i used a 115mm Angle grinder with a 2mm cutting blade , very thin but you get a nice clean cut .
I then marked out and cut the hole in the front and drilled some air holes round the bottom and holes for some tent pegs to act as pot holders .
I also cut the bottom of the cup to use as a pot lid .
here it is with a trangia burner and 1 litre of water .
1 litre of water to a rolling boil in 14 minutes .
The stove body with 4 pegs and the pot with lid weighed in at 540grams .
I am off out for a walk this afternoon so will give it a try with some wood ,if i can find any as it has been raining most of the morning .
After lunch i went of for a walk in butterdean wood which is just of the old A1 at Gladsmuir in East lothian .
The wood is mixed with some good sized older trees and is looked after by the woodland trust .
The rain managed to stay off but the wind is blowing a fair bit , i could see a challenge on the way with wet wood and blowing a gale .
I found a quiet spot in the middle of the wood with some dead standing trees nearby .
Before setting fire to an old flask please drill a couple of holes in the base of the flask in case there is a vacuum sealed base just like this one had , i didn't fancy the stove blowing up in my face !
As i was setting up the stove i realised that i had left my camera plugged into my laptop at home so this one was done with my phone .
The boil time for 1 litre of water on wood was just over 10 minutes, a little bit quicker than on meths .
