10:30 "By feel?" Doesn't your drill press have a stop? Just set the stop to 1/32 below the surface, and you will drill all the way through the outer skin, without coming near the inner wall. Only if you are drilling by hand would you need to go by feel.
An old fire extinguisher makes the best stoves. They're made out of 1/16 thick aluminum which makes them more resilient. Cut three inches off the top and from the bottom, file a notch the lip of the top then press it into the bottom. Drill the 1/16th" holes on the side and fill it with fuel. Once its hot and the pressure builds, they're as good as the commercial ones.
I build stoves too. I have copied many designs but designed the MAHALO stove. The MAHALO was designed to be fuel efficient as possible, light weight, have a tight flame pattern for small pots. That stove has worked under a 24 OZ beer can 2 7/8 inches in diameter. Up to a 7 1/2 inch stainless steel pot.
thanks dude for that awesome video and that is a great little thing that i think i might use on my next hunting trip up north to show the guys a cool little stove
Built one of these earlier today, and it actually works! Will wonders ever cease. It takes about a minute to prime and will boil 2 cups of tap water in about 6 minutes, with no lid on the pot. I drilled 1/16" diameter holes for the 16 jets, about 5/8" from the top edge of the stove.
While sitting in the Dublin airport sloshing down Guinness my buddy said drinking two glasses of Guinness is the same as eating a loaf of bread. So true.
I did one but with a change. There is an indent near the threaded part (holds cap retainer ring). I took side cutters and cut 6 times around from the opening to that indent. I peeled back those 'tabs' a bit. Theory is to allow more heat transfer into the fuel and if you bent them correctly, they will touch the inner wall of the bottom can. More heat transfer and stiffens things up. You get 6 'slots' for alcohol to go from the neck into the inner chamber. My problem is cutting things straight and getting the top rolled correctly. Mine looked AWFUL. Going to test is here in a few hours to see how it works. (Fire department on standby! LOL)
Ever notice that everyone drills holes for the jets but no one cuts 45 deg angle slots for the jets? I wonder what the difference is between the size and number of holes in the stove.
My guess is it's easier to use a drill than file slots. What we need to discover is what is the return on that extra work for the slots. Perhaps fewer slots but more output? It's a great thought. What are your thoughts? Perhaps I'll get into my work shop and try it out! Thanks for the idea!
Good catch! I cut so many cans that day I can't remember what I used on what build. If I remember correctly the trim I made ended up making it too short so I measured and cut another can to the right height, to begin with. To save time on the video I just didn't show it all. The final outcome was a working stove. Lesson learned, just have a few cans around just in case something goes sideways. Learned a lot that day. Thanks for watching. If you build one, we'd love to see it. Tag us on Instagram! @theshootinguy.
If you mean automobile Gasoline, NO. Gasoline has far more energy than alcohol by volume. The little 'pop' that happens when igniting Alcohol, will be a sizable explosion possible of ripping the can apart and spewing gas on other things and you. plus Gasoline has a lot of other chemicals in that are useful for motors, but unhealthy for humans should it contaminate the food.
Two problems w stove 1. The flame pattern is too big to work with most camp pots. GSI minimalist, snow Peak 600 and other cups. 2. The jets are too close to the top. 1/2-5/8 from the top is standard.
