As of lately I have been quite interested in making some of my own gear and other things here and there. Having finally got my sweaty hands on a few Venom energy drink bottles I thought they would make awesome Alcohol stoves.
These bottles are made out of roughly 1/16" thick aluminum. They are much thicker at the neck and at the base. As well they are VERY beefy.
Image
---------------------------------------------------------------


Browsing the internet for ideas on how to make them I have come up with these first two stoves.

This one is a bit of an ugly duckling. It has inverted jets which will require the use of a pot stand which is no big deal for me. It has a fuel port on the side and the inside of the stove is sealed other than for the jets. It stands at 2-7/8" I have yet to test it.
Compared to the next stove it should have a longer burn time since it only has 8 jets.

5/3/2010: Tested it today and it has a boil time on 1 cup at 4 mins and a total burn time on 2 ounces of fuel at 7 mins 40 seconds.

5/4/2010: Been giving it some thought lately and have decided that I am going to make a dedicated pot stand for this stove since it would be more convenient

Image
Image
---------------------------------------------------------------


This stove is made quite similar to the first except it is not a full pressurized stove. It has 24 external jets which is a few too many for the size of the holes I was using. I tested this one today and got about 4 mins and 25 seconds boil time off 2 cups. with an overall burn time of about 8 mins on how many ounces of alcohol I am not sure. Out of my own stupidity I was too excited to remember to use a wind screen so the boil time could have been reduced by using one. I will not make that mistake again. I will test it once more to get a more accurate boil time. I was able to make some tasty spaghetti though! YUM!

---------------------------------------------------------------


Today I started working on this little baby. It is much smaller and lighter so far than the first two. This one is based off of most soda can alcohol stoves, in a way. It is made of the bottoms of two Venom bottles which one is inserted into the bottom of the other with JB weld sammiched between the two to provide a seal. The lip of the outside can is rolled over the bottom of the inside can. It has a fuel port on the top which will have a screw and nut to seal the port while in use. I have not had the chance to jet this one yet. I am waiting until I test the inverted jet stove to see how well 8 jets works compared to the 24 jet stove. This one should be able to hole a about the same amount of fuel as the first two, give or take. It stands at 2-1/8".

5/3/2010:Added a picture of the Double bottom stove before rolling the edge and brushing off the decaling.

5/4/2010: Jetted the double bottom stove. 8 pin sized holes to start with. Will add more based on performance. Will be filling the bottom mistake fuel hole tomorrow and testing it sometime in the next few days.

5/10/2010: Tested this stove today. I started to prime it and it took a while to prime and would not start on the first try. I jetted it with more pin sized holes which now add up to 24. It burned for 25 mins and 15 seconds on 2 ounces of fuel. Boiled 2 cups in 10 mins. Which took way longer than I had hoped. After the test I made 4 of the holes into 1/16" holes to try to cut down on boil time. Am thinking about adding a wick around the bottom of the outside of the stove to help in priming it. Added a picture of it in action as well.

Image

Since I started to make this one today I have been thinking of lots of ways I can improve it. Such as setting the fuel port on the end that does not have the seam For more accurate jetting closer to the rim. I might Just slip a screw into the existing fuel port and JB weld it up to go with this new idea.
---------------------------------------------------------------


I will definitely be updating this when I get my hands on more of these bottles and when I test the other two stoves.

Please leave some constructive criticism or whatever you want :D


Overall Updates:

5/3/2010: Going to be testing all the stoves with 2oz of alcohol. For more of an accurate burn times and boil times, starting with the inverted jet stove today.

They are quite simple to make and require little effort. Just a dremmel with cut off wheels, drill bits and a grinding wheel. Some JB weld. The red and black kind. Not the quick kind.

I used steel wool to brush off the labeling too. You can also make them much smaller. The first two were my very first tries. I could have cut off about 1/4" from the top and made it much smaller as well I could have made them overall smaller buy cutting about Half an inch off the bottle neck before fitting them together. Though it would reduce how much fuel you put in it, it would make it much smaller.

I dont know if a 4 min boil time of 1 cup of water on 2 ounces of fuel is good.

Also that 2 ounces only lasted 7 mins and 40 seconds. That sounds not all efficient. Any suggestions?

Nice. Of all the DIY designs i like the ones made from the heavier walled bottles best.

Take note: This won't officially be stove porn till we see some flame shots. :wink:

couple of ideas regarding efficiency:

*always use a windscreen.
*match the pot to the flame pattern... make sure the flames don't shoot around the sides of your sexy new snowpeak kit.

If they shoot out too far I need more jets, correct?

I dont know if I have too many or too little jets. It burned through that 2 ounces of fuel in almost 8 mins.

EDIT: I will get some flame shots soon. I didnt get any today since I was using my phone as a stopwatch :P

Also what are your views on external jets and internal jets? I dont mind either of them as long as they are efficient.

I used the Venom bottles to make a couple of the MB designed Budlight stoves.

They work scary good - boil water in no time flat in my Al pots, weigh nothing and are cheap to make.

Pure win IMO, even more so with the thicker bottles.

It's very similar to your first version, but without sinking the top into the bottom.

Essentially you cut the bottom off another can, and use it as a press to invert the stove can's single wall into a double wall, folding the can back onto itself.

Here's a pic with fire (you can kind of make out the inverted can, as the Venom logo's upside down):

Image

When you put the pot on the stove, it seals the top and causes the stove to pressurize, causing the jets to really push out. The Al pot in this picture is about 7" wide on the base, and you can see the flames around it.

Image

It boils incredibly quick, and eats fuel like mad.

Could you go into a bit more detail on how to press the single wall into a double? Im really interested in trying this. Though I wonder if there are ways to make it more efficient.

Sure - a couple thing's you'll need to do this though:

1) A good sized 5" vise - you'll use almost all of the 5"
2) Air compressor or some source of compressed air (tank, whatever)
3) water based lubricant of some kind -your choice...
4) two pieces of 1/4" steel, wide enough to span the Venom bottle evenly as just using the jaws won't work, you need more surface area to evenly press the cans together.

Steps:

1) Cut one can off 1.6" from the bottom of the can
a) Put a good sized hole in the center of the bottom, but small enough for the nozzle of an air blower from a compressor to seal against
b) Lube up the inside of the 1.5" tall bottom
c) Using a full, unopened can slowly and even press the full can into the bottom to evenly open the bottom to the outter circ of the full can - about .5" is all you need to go, maybe less.
d) remove the widened open base (via air pressure or just work it off, your choice)

2) Cut a second base off at roughly 3.75" or so.. you'll need to play with the length to see how far you can go and still fit your vise. (note: if you're using a vise or press larger than 5", you can go as tall as the can is until it curves in, just remember the final distance will be halved)

a) Clean up the edges
b) Lube the inside of wided 1.6" bottom and the OUTSIDE of the 3.75" bottom
c) Fit the 1.6" "cap" onto the 3.75" bottom, and seat it securely as far as you can by hand
d) Place a piece of flat steel on EACH SIDE of the bottoms, and place EVENLY in the vise so that it's centered for pressing

3) Hand tighten the vice making sure everything is centered
4) Use a cheater bar on the vise and continously and evenly apply pressure to collapse the can bottoms into one another

***NOTE - the tall bottom will FULL INVERT BEFORE the small bottom has reached the outter edge's bottom - go slow, and remove the piece as you crush it. Open the piece by air pressure to check the distance traveled. Lube and re-crush as necessary.***

5) Once the can has been inverted, use the compressed air nozzle to pop the inverted can out of the shorter "mold", and you're 95% done.

6) Drill jets .75" down from the top edge evenly spaced, I used 1/16" or smaller. 20 is almost too much, but 16 is almost too little...

7) Drill two holes opposite each other (1/16") about 1/4" down from the top edge of the inverted can on the INSIDE wall - this is a vapor release gap to keep the stove from over pressurizing when you seat the pot onto the stove, and blowing the pot off the stove once it's up to power...

***NOTE - If you accidently over crush the can and the inner wall closes against the bottom, it's not an overly huge deal. Get a 1/4" bit and drill at an angle into the inner wall to open up a gap in a couple places to let the alcohol into the wall. Go slow, be careful. ***


Fill with Yellow HEET or SLX - avoid using Red HEET or methanol based alcohols, and don't use the 200 proof lab grade stuff I have in the picture - the flames are off the chart.

Have fun!

Lol I dont have a vice right now. that will have to wait for a while. The autozone near me sells heet for around 1 dollar. which is cheaper than rubbing alcohol or denatured alcohol around here. going to stock up on that when I get more autozone rewards points.

Thanks for posting the instructions though. I will try it when I get access to a vice.

Yup, some of us have been making stoves from these bottles for quite a while... see here for one I posted briefly about back in January 2009 old thread

A couple others I built... Image

These days I'm liking the Bud Light bottles a bit better, they're smaller and have a flatter bottom than the Venom. My Bud Light paired with an MSI soloist pot is probably my best (although not lightest) alkie cookset.

Do they still sell bud light in the cottles? I have been looking around to see if I can score some of them as well I have quite a small stockpile of venom bottles now since my brother in law has been behind some of the stove ideas I have been throwing around.

The bud light bottles would have more of a advantage over venom because the neck on the bottle is much smaller and it would let you have more fuel in it if needed. I have a newer stove that I need to test soon. I have been out of town so I cannot really do a whole lot but it will definitely happen soon. I hope that I can get to make most of my wood stove today as well since I will have the tools for it at my disposal.

I will update you guys soon.

Odd... I wonder where my post went.

I think the Bud light aluminum bottles are most commonly sold in stadiums where glass is prohibited. Luckily for me, a local bar does carry them. Emptying them is just my cross to bear- I don't drink any kind of soda at all so if I needed a Venom bottle I'd have to give it away or pour it out.

I have tried buying them at beverage stores and always struck out, but some of them probably do carry them.

I have only found Venom at BP, Circle K and Marathon stations. I have been keeping an eye out for bud light cottles since I would like to try and make some stoves out of them.

At the risk of necroing, I remembered that some of the canned coffee I used to drink (Mr brown or something?) had a thick steel can, since it was not carbonated. I could stand on it with a rather lightweight friend on my shoulders with no deformity at all.. Keep an eye out for Asian Canned Coffee, and squeeze some cans. You may be pleasantly surprised.

Cheers.

Today I started working on this little baby. It is much smaller and lighter so far than the first two. This one is based off of most soda can alcohol stoves, in a way. It is made of the bottoms of two Venom bottles which one is inserted into the bottom of the other with JB weld sammiched between the two to provide a seal. The lip of the outside can is rolled over the bottom of the inside can. It has a fuel port on the top which will have a screw and nut to seal the port while in use. I have not had the chance to jet this one yet. I am waiting until I test the inverted jet stove to see how well 8 jets works compared to the 24 jet stove. This one should be able to hole a about the same amount of fuel as the first two, give or take. It stands at 2-1/8".

5/3/2010:Added a picture of the Double bottom stove before rolling the edge and brushing off the decaling.

5/4/2010: Jetted the double bottom stove. 8 pin sized holes to start with. Will add more based on performance. Will be filling the bottom mistake fuel hole tomorrow and testing it sometime in the next few days.

5/10/2010: Tested this stove today. I started to prime it and it took a while to prime and would not start on the first try. I jetted it with more pin sized holes which now add up to 24. It burned for 25 mins and 15 seconds on 2 ounces of fuel. Boiled 2 cups in 10 mins. Which took way longer than I had hoped. After the test I made 4 of the holes into 1/16" holes to try to cut down on boil time. Am thinking about adding a wick around the bottom of the outside of the stove to help in priming it. Added a picture of it in action as well.

Since I started to make this one today I have been thinking of lots of ways I can improve it. Such as setting the fuel port on the end that does not have the seam For more accurate jetting closer to the rim. I might Just slip a screw into the existing fuel port and JB weld it up to go with this new idea.

I will definitely be updating this when I get my hands on more of these bottles and when I test the other two stoves.

Please leave some constructive criticism or whatever you want :D


Overall Updates:

5/3/2010: Going to be testing all the stoves with 2oz of alcohol. For more of an accurate burn times and boil times, starting with the inverted jet stove today.


Hello, I just made one of the Mini Zen Chimney/Sideburner Stoves from a 6.5 ounce Starbucks expresso can.

It's not nearly as nice as the one illustrated, but I'm pleased with my first effort. I fueled it up with some 99% rubbing alcohol and it seems to work okay. Definite room for improvement, too much orange and not enough blue flames. Hmm... too much fuel venting? So next time I will use 6 instead of 8 side vents.

This link http://zenstoves.net/Stoves.htm has interesting information on alcohol stoves and lots of practical information on home manufacture of various types.

Don't use rubbing alcohol.... use denatured alcohol :) Either "Heet" in the yellow bottle, or get denatured alcohol from the paint section of your local hardware store.
