I want one. on 06/01/2005 02:51:53 MDT Print View

Looks like a great stove. I think I'll fashion one up on the weekend. I think its funny that we call them stoves when they are so small and light.

Just on the side, I've always been a closed jet kinda person. I like that they get going a lot quicker are a lot hotter and better for windy conditions.

I've always made the inside wall with the gaps to let the fuel through much too big. I think this might save me a lot of frustration when I dont want to completely boil water and I only put a little fuel in there.

Thanks Jay

Simmer Ring on 06/01/2005 05:19:08 MDT Print View

A Simmer ring made out of the top portion of the a can as per section
10 of:

is worth the time. My fuel filled Thermojet stove with this burns for just under 60 minutes. This allows a homemade "bakepacker-like" boiler/baker to be easily used to cook anything. I made the "bakepacker-like" boiler/baker out of the new floppy silicone muffin baking pan supporting a round-cut piece of cookie cooling rack. The silicone baking pans look, feel, and pack like rubber but take the boiling without problems. All of the supplies came from Wallyworld. The system works very, very well. Very little additional weight. No clean up when cooking in plastic bags.

I reviewed an AMP closed jet, and though they are powerful hot and truly efficient boilers, I really prefer the fill and forget nature of these open jets. I have been using this same stove for five years as my standard. Even when family camping, I just take two of these and two Evernew pots (the 1.3L and 0.9L nest together).

I am heading to Canyonlands this weekend. So if you dive into this stove project and need some questions answered, I'll be back on Monday.

floppy silicon? on 06/01/2005 08:07:32 MDT Print View

Can you tell me more about your "floppy silicon muffin baking pan supporting a round-cut piece of cookie cooling rack"?

I have tried several "simmer ring" type gizmos, and all of them slow the burn time and reduce heat. I quit using them, however, when I read an article written by Carol Crooker. She described making a bakepacker-like boiler/baker out of aluminum soda can material.

I altered her description a bit. I cut 1/2" strips around the circumference of a soda can (length of one strip is once around the can). I wrap these around a pencil/dowel to give them a spiral shape. These nest inside my stove and weigh nearly nothing.

I place two or three of these in the bottom of my pot, add water to just below the tops of the spirals, and place my half-filled aluminum muffin cups on top. With this arrangement, I just fire the stove up at full throttle with about an ounce of fuel and forget about it for a while, leaving the muffins in the pot well after running out of fuel. You might notice a trend in my cooking...I don't like to fuss with it much, just light and forget.

I suggest folks give Brad’s suggestion a try. Experimentation leads to experience. Some will find it ideal for their cooking style. Definitely use a make shift bakepacker-like boiler/baker if you want to bake. I have successfully baked pizza without bakepacker-like rings or a simmer ring, but don’t recommend it. It is certainly not worth the fuss.

Fuel efficiency on 06/01/2005 13:33:38 MDT Print View

How does the fuel efficiency of your stove compare to some of the other alcohol stoves reviewed a few months back?

Have you ever tried making a stove with smaller cans (V8, energy drinks, etc)?

Dremel Clone on 06/01/2005 18:04:28 MDT Print View

Excellent instructions Jay. I have attempted to make stoves of this type in the past with varying success. I had the most trouble with cutting the bottom out of the can as depicted in photo 5, and fitting the pieces together as depicted in photo 32. In the past I used a utility knife instead of a Dremel. Next time I'll either borrow or buy the power tool and follow your instuctions.

Which brings me to my subject. Go to and enter item number 40457-1vga in the search box to see a Dremel Clone with tools for $29.99. A buddy at work bought one and is happy with it. Probably not as good as a Dremel, but probably good enough to make alcohol stoves!

Non-Scratching Baker/boiler on 06/01/2005 19:20:24 MDT Print View

After getting a new nonstick titanium pot I decided that I needed a non-metalic replacement to a bakepacker. On a trip to Wallyword I found a whole new world of baking pans that are made of very floppy silicone. You can cut these with almost anything and they obviously can withstand the heat. I purchased a standard 6"x9" 6 cupcake silicone backing pan. I cut one of the 6 cupcakes out. I flipped it so that the open side was down and measured 1" up from this new base. I cut at this 1" mark to give a band of silicone that is now bigger and the bottom, 1" tall, and then smaller at the top. This serves as a heat-proof non-scratching base which holds up a cut to fit cookie/cake cooling rack wire grid (from the next isle over at Wallyworld.)

I guess using 3 1" rocks to support the wire grid would work also.

I would like to coat the wire grid with something to keep it from scratching the pot as it stores in it while in my pack.

A picture here would help but I hope my discription will do.

Carol and Jay what article? How do you keep from using up all of the fuel in less that 12 minutes without a simmer ring? I am getting just under an hour with a full burner with a simmer ring. I do get the water to boil with the ring first then drop the simmer ring on the burner. Even with the ring there is enough heat to keep things boiling in the summer. I suspect that this would not be the case in the winter.

You asked: "How does the fuel efficiency of your stove compare to some of the other alcohol stoves reviewed a few months back?"

This is a can of worms. :) The short answer is that my stove is very efficient (it's not really mine, I'm just partial to it and developed a way to make one that turns out real nice). I can cook (not just boil) most meals for myself and a companion with 1 fl. oz. of fuel, which is how I estimate how much fuel I need to carry.

To say how my stove compares to the others we tested is hard to do. Will tested those other stoves as they came from the manufacturer, with the manufacturer’s supplied windscreen and accessories. Although my stove may be similar to the OutdoorEquipmentSupplier 12-jet stove (which had slightly better than average efficiency) you can't just compare the stove. The windscreen, pot support (height), pot size, pot shape, pot color, number of jets, etc. must be considered as all of these affect how heat is transferred to your food. Homemade alcohol stoves are plagued with variables. A different windscreen or a few more jets may make all the difference in the world. Part of the fun is tweaking the variables to balance boil times with fuel efficiency for your particular setup.

You asked: "Have you ever tried making a stove with smaller cans (V8, energy drinks, etc)?"

I haven't, but would expect the same step-by-steps to work for any size can as long as the cans used were the same size. I never made a smaller one because the standard size weigh so little as it is; dropping weight off of a 0.4 oz fully capable stove has never made it to the top of my priority list. With that said, Carol's recent super ultralight challange has got me thinking about it.

Honestly, I won’t profess to be up on what power tools are best. If it can make a cut off wheel spin, it should be able to cut out the bottom of a can. That aluminum is pretty thin and soft. If your buddy at work has one, you might give his a whirl (nice pun, huh) to see how you like it.

Thoughts on a windscreen? on 06/02/2005 09:17:55 MDT Print View

Jay - thanks for the clear instructions. As the review of other stoves made clear, the stove is only half the you have any thoughts on creating an optimal windscreen?

If it will simmer you can bake like this. on 06/02/2005 10:33:59 MDT Print View

If your stove will simmer for 18 to 20 minutes you can bake in a dry cook pot like this. The small pan you see in the pictures was part of four connected together that I bought at a local restaurant supply store. I broke them apart to carry only one. the small pan weighs 1.3oz. Not really Ultra-light and I have plans to make a small pan out of titanium.

A real and warm baked muffin at the end or at the beginning of your hiking day is really great.

What ever stove you use needs to simmer really well.

cutting bottom out of soda cans on 06/02/2005 14:11:37 MDT Print View

OK the cutting process is quite simple. Go to WWW.MINIBULLDESIGN.COM and watch the video where I make this soda can stove from scratch in 3 minutes. You will see how to cut the end out of the can no problem. And probably see some other tricks you can use also. No purchase required.

why not punch the jet holes before cutting the fill hole? on 06/04/2005 01:44:47 MDT Print View


Is there any tendancy for the can to collapse under the force of pushing the needle thru the wall?

Seems like it'd be a little sturdier if that were done before cutting the fill hole.

Any reason not to?
