Wood Stove

It's been a while since I added anything here but I've been reading recently about the "Bush Buddy" wood stoves (and clones) and wondered if I could cobble something together. I'm not sure if I've even got the basics right but I did manage to boil 400ml of water in 15mins from lighting. That said it took about 15mins to prepare the wood. I used 3 x 6" lengths of 1"x 1" firewood and split it down first with an axe and then with my knife, I also made a pile of shavings from some of the pieces.

The non scientific part.......

I used a stainless teapot (bad choice as it let heat escape through the spout and I guess SS is harder to heat than Aluminium)

Temperature was around freezing but there was no breeze.

The Build.......

I used what was to hand, a coffee tin, a cat food tin and a tuna tin. The coffee tin had a pop-off plastic lid but when it was open there was a lip/edge on the inside which was a more or less tight fit on the cat food tin. I did have to roll the lip back a bit to let the cat food tin fit. The reason I used a cat food tin was that it had a rounded base rather than one with a lip which meant I could press it into the outer (coffee) tin more easily. The Pot stand was made from a tuna tin which when cut sat nicely on the lip of the outer tin but could be stored by sliding it into the base.

I started by cutting the base from the outer tin and making some air slots around the bottom, I then made two rows of holes in the inner (cat food) tin, one row about 10mm from the top, another the same distance bottom, the holes were about 10mm dia. I then punched as many holes in the base of the inner can as possible. To make the windshield/pot stand I cut a section from the tuna tin, removed the base and made a few vent holes (it might have been easier to use a tin like pineapple rings come in as most have a base that can be opened with a tin opener)

The End Result.......

Really rough build but it's ah .................... um................

....... a work in progress :-)
