Introduction: Cat Stove Pt1: Alcohol Fueled

Picture of Cat Stove Pt1: Alcohol Fueled

hi today im going to make a cat stove and in a following instructable a windbreak and potstand hobo style.

Step 1: Materials List

Picture of Materials List

to make this stove you will need :
2 cat food tins (1 156gram and 1 85 gram)
the lid from the bigger can
some muffler repair tape
a small piece of pink fibreglass insulation

hole punch
can opener
file or dremel

Step 2: Punching the Holes

Picture of Punching the Holes

take the small cat food can wash it really well {this is in case you nick yourself making this thing pretty stupid to loose a finger to blood poisoning for a hobo stove wouldnt it?}

PIC 1and 2 use the hole punch to make a hole in the can as close to the top as you can make it.

PIC 3 make another one exactly opposite.

PIC 4 punch more holes in the middle of each unpunched segment until you have 16 holes. the number isnt super critical but fewer will give you a slower burning stove

Step 3: Time for the Big Tin

Picture of Time for the Big Tin

PIC 1 now take the cleaned up larger can
PIC 2 punch a hole in the center big enough to get the point of a scissors or tinsnips into it.
PIC 3,4 start a curved cut out to the edge of the crease on the bottom it makes a convenient template but if you want to you could make a smaller hole.
PIC 5 cut the center section out {use the file and sandpaper to clean up the edge of this hole it is razor sharp and most likely barbed.{ i hope you cleaned the can well cause here the most likely spot for a bit of gratuitous bleeding}
PIC 6 ,7,8 use the large can opener to open a triangular flap in the side of the can .then do it seven more times evenly spaced.(be careful here too and sand up the edges]



Time to put the major parts together.
what you should have at this point is a small tin with holes around the rim and a larger one with triangular holes and inward protruding tabs.PIC 1
Pic 2 take the small tin and place it upside down inside the large one.
PIC 3 its essentially finished at this point if you dont have the muffler tape.
PIC 4,5 take enough aluminum muffler tape to go around the can and split it up the middle{you could use it full width but it isnt really necessary .
PIC 6 Wrap the Tape around the can so it forms a tube. then drop the lid in and fold the tape down to hold it all together.
all is left now is to put the fibreglass chunk into the can so its loosely filled. you could also use vermiculite for this too but then you would need to put a fine wire mesh in the top to keep the loose stuff in. the fibreglass will hold its shape after the first burn.

Step 5: Why We Need a Filler

Picture of Why We Need a Filler

im sure some of you are scratching your heads and wondering why the fibreglass.
fair enough ill tell you then. the glass or the vermiculite{i love that word} is there to act like a wick and and provides the following benefits.
even burn...the fuel doesnt boil itself away.
minimise spills... the packing holds the fuel and in the case of a tipover only the excess fuel spills.
gives you something to make out of that itchy plauge errr i mean fiberglass.
and also gives me a reason to say vermiculite lol.
there thats enough shouting to suit the lawyers
tune in next time for a combination windscreen and pot holder made from a coffee can.

Fiberglass insulation is not needed.You can use cotton (100%) as a substitute for the fiberglass insulation.

minhocaloka (author)lennyb2009-06-18

ahwheahwehaweh, cook the cat!=D

funny, nice instructable man!=P

lennyb (author)minhocaloka2009-06-20

glad you like it. but i still haven`t got any good kitty recipes yet.

bylerfamily (author)lennyb2009-03-17

Haha.Once my friends brother barbequed a cat and gave it to his teacher and she said it tasted like chicken.

rramos1 (author)2011-04-05

I like your design, it's simple, easy to build and materials are always available. thanks for sharing your idea. Godspeed !

RonM (author)2009-02-27

An alternative to punching holes in the small can is to use a can opener (like with the bigger can) but push from the inside out. That leaves a circle of outward facing triangular tabs at the top of the small can. These tabs rub against the inside wall of the outer can, keeping the inner, smaller can centered. Thanks for the instructable.

javajunkie (author)2009-02-06

thanks so much for the great tutorial - you're going to be the star performer for our Scouts! We're bringing in the laptop and presenting your tutorial to make our stoves for camp... hey, work smarter, not harder - you've already done all the hard work! And, don't worry, we'll be sure to teach them to say "vermiculite" a whole bunch!!!

lennyb (author)javajunkie2009-02-07

heh heh thats great i hope the kids have fun making them. and tell them hello from the wilds of newfoundland for me will you?. later

avicena (author)2008-12-27

can it use bioethanol 40% as the fuel?...

lennyb (author)avicena2008-12-27

40% seems a little dilute. you can always try it and see

campoutnow (author)2008-10-17

thts a cool idea!

Superninjacamper941 (author)2008-07-23

Thanks Great Instructable!!!!!!!!!!

Superninjacamper941 (author)2008-07-22

Hey how do you light the stove?

just a match or a lighter is all thats needed. nothing fancy. as for the fuel in your other question its fondue fuel that i get at the local dollar store. you can also use gas line antifreeze or methy hydrate. rubbing alcohol also works but try to get the stuff that has less water in it. dont use gasoline it will explode and melt the tins

Superninjacamper941 (author)2008-07-22

Also what kind and what brand of Fuel do you use?

leebryuk (author)2008-05-21

Nice job. One step missing though. You must have a hungry cat nearby. It's good form to feed one's cat with cat food being used for a stove.

lennyb (author)leebryuk2008-05-22

no problem there . we have two cats and they are pigs.{not really though} i usually make 40 dollars a year recyling the aluminum catfood cans so that will give you an idea how many. actually some of the food coming out of the pricier cans looks good enough for me to eat.. lol hope they still make that when im retired unless i get rich or sumptin.

FunkLiberationFront (author)2008-04-21

Nice job. I made this same one a while back, but I need to add the aluminum tape to it like you did, that would improve it immensely. I also created a pot stand for it with a loop of chicken wire, works great.

struckbyanarrow (author)2008-04-16

hehehe i thought it was a stove to cook kittys in!

ak49er (author)2008-03-08

Doesn't most fiberglass treated with chems that are toxi when burned?

lennyb (author)ak49er2008-03-09

only if it were coated in resin. this is the spun glass wool and whatever non glass chemicals in it will burn away with the first use. for the first burn id recomend well ventilated conditions but with a stove of this type i dont expect many folks will try to use it in an enclosed space.

You can use cotton balls instead of fiberglass it wont last as long but might be easer to find/use.

actually the fibreglass is better for a wick than cotton for the following reasons. 1 the cotton will need to be replaced everytime you use it. the fibreglass will last the life of the burner. 2 the cotton will contribute carbon to the flames and soot up your best hobo pots. fibreglass after the first burn in will add nothing. 3 people will want to use your wick supply to apply makeup or as beards for santa claus if you use cotton. with fibre glass the same is less likely.

Iv been to reuse the cotton several times so far. I created a slide show of my stove (using NK5's instructions)
I did make a few mods to his design.

PyroMaster007 (author)2008-01-31

why is the insulation neccesarry?

lennyb (author)PyroMaster0072008-01-31

the insulation is to provide a wick one that wont burn up the flame burns longer than if just the fuel alone were used. i tried it both ways

KNOTTYMAN (author)2007-12-28

I used to make camp stove out of carboard,parafin wax,a piece of rope and a tuna can. I like this one. vermiculite

TheOtherMikeS (author)2007-12-10

A couple of points: A pinch of salt in the alcohol will make it visible. I get my best performance with denatured alcohol. Get it at any "big box" store like Home Depot or Lowes in the paint department.

lennyb (author)TheOtherMikeS2007-12-10

thanks for the tip

the gizmoman (author)2007-07-07
