View Full Version : Where do you get your cans?

PROBLEM: I don't have enough of the particular cans I need for all the stove ideas I want to try. I don't drink enough beer or soda. I don't like V8, energy drinks or prune juice. I like the Starbucks double shot espresso drinks, but I'm too cheap to buy something I can make at home.

SOLUTION: Scavenge cans from friends, neighbors, work and along the roadsides. They're free. In winter, the roadside cans aren't too funky and nothing is living in them yet.

OBSERVATION: Miller Lite is the beer of choice for people who drink beer in their vehicles and throw cans out the window.

What are your solutions and/or observations?

12 ounce sized cans are very easy to get, it is the smaller ones like Red Bull or V8 that are slightly harder. Usually drinks coming in these are on the expensive side especially compared to what you get. Right now I have been using V8 Splash fruit drink since the kids use them and my wife said something about making Tequila Sunrise out of 'em.

I'm looking for a source of bulk cans now though. I have actually thought of migrating away from drink cans into something else.

Something like this, but not this exact tin.

It would need to be aluminum instead of tin (steel) and I wouldn't want a rolled edge at the joint of the can.

one idea for getting smaller cans is to stop into a blood donation center - often they hand out the small V8 or whatever drinks to people that donate and they often have a waste container / recycle box full of the empties

I made something like the ion stove with that kind of tin -- mints from Target, I think. I tried another kind of stove with a different tin of mints. I don't remember where I got the original tin, but I found another one like it at Dick's ($3, maybe $4, for a tin of mints, yikes). I'll try to post a photo of them when I get home. They are relatively heavy.

Ha! Ain't it weird how our concept of heavy is now measured in fractions of an ounce?

I got "connections" for my 12oz cans.

As for something else to make small stove with... I have it. I havent bought it yet (paycheck comes friday) but they are the PERFECT size, are aluminum, and basically just kick ass

But its my precious, mine, my own, and you cant have it! http://www.movie-vault.com/cgi-bin/forum/images/smilies/lotr_gollum.gif

Yes, but it is fun sometimes.

I did find this site:
http://www.oshun.ca/Merchant2/merchant.mv?Screen=PROD&Store_Code=OSI&Product_Code=P183A

http://www.oshun.ca/Merchant2/graphics/P183.jpg

The per unit cost would be about $0.84 US (this is a Canadian site) for a stove before the shipping costs from Canada which I didn't check out. This makes it a little less expensive than buying full cans of V8 juice and re-tooling them. I don't know what the weight is and I would probably need to make some new templates for a couple of things.

Sarge;
Is that a "loonie" or a "toonie" for comparison in the background?
Is this from the Kanuks, or did you make this picture yourself?
These look like primer (or cap) tins for muzzle loading guns. I've got a few in the basement I've been dying to utilize for something, since I use maybe 2/year. More, since I got this Ruger "Old Army" revolver to shoot (dad-gum semi-automatic).
Or maybe they're airgun pellet tins. I use even more of them (maybe 4/yr).

I want to see you make a stove out of whiskey bottles. I could make you rich using them!

The pic comes from the site, not me. I don't know what the coin is. I think I had some tins like this too at one time for pellet guns or something.

Many watering holes now push Red Bull & vodka type drinks. Seems every bar in this part of the world has a big banner advertising Red Bull (and similar). So.... Just get friendly with your local bartender and ask them to save the cans. I would guess they throw out 50+ every week....

rock, you remined me of something... let me see if I can find a similar mint tin...

found one... http://www.inparticular.com/products_mints.htm

they handed mints out in these at a college career fair I went to a long time ago. hella small, probably barely holds the 12ml you're looking for. doesn't have the rolled edge of the above

here are the blanks with mints... http://candy.en.alibaba.com/product/50012765/50231377.html 16g / tin with mints... maybe it's not quite big enough... wait... 45mm diameter = 22.5 mm radius => 22.5 * 22.5 * pi * 15 = 23856 mm^3 = 23.8 cm^3 (ml)... hmm...

unfortunately minimum order is 50,000

It looks like a plastic container.

no, their metal, I cut my self on mine

btw - they are 16g of mints per container... gotta find raw containers...

Those tins look ideal for the simplest stove around - just fill with perlite and crimp a bit of window screen in place. The lid would let you snuff the flame - perhaps in time to save a bit of fuel at dinner for the breakfast refill. A thin sheet of foil for a 'simmer ring' would round things out nicely.

18lb / 100 .... 67g each - 16g candy = 51 g each (maybe less as some might be packaging)

From these that you found
http://www.specialtybottle.com/index.asp?PageAction=Custom&ID=25

they have the 1/2 one that, by my calcs should hold 12ml + (closer to 16ml)

These buys might be able to hook you up with just the click cans...

I used that kind of tin to make a stove, thinking the slots around the edge would work as pre-fabricated burner ports. It didn't work very well. I've been looking for more of the tins since then, because I've had people interested in a little stove that could be carried in a pocket. The lid makes a good little base that isolates the stove from cold ground. Your Ti-pod stand, because it comes apart into flat pieces, would be a good mate for the stove.

Here's the photo I promised earlier. The one at lower right is the Target mint tin. The quarter is for size reference, not covering a hole in the center. Originally, I could take the lid off to fill it, but after a couple of firings the thing fused shut. I made the holes a lot bigger and depressed the top so I could fill it by tilting it slightly and pouring fuel onto the middle of it.

I'm working on a version using aluminum candy tins (yes I found some, but it ain't cheap) and they perform better than the V8 cans with the addition of 1 gram of weight, but they are also a little bit thicker. The test model actually boils water a little faster and more fuel efficent, and with the current build I can take the lid off after putting the stove out and pour the leftovers back into my fuel container.

What's an extra gram of stove weight if you save ounces of fuel? Got photos?

Not yet. It is still a concept idea that may not work out, I have to play with it a little first, just picture a tin like the ones I posted previously painted blue with the same hole pattern that my Ion Stove has and you see it.

Well if you figure cost per tin it isn't bad, $0.84 each, but you have to buy $80+ US before you can make an order. I found some tins that have plastic lids at $0.75 each, but it takes two to make a stove since you have to take the bottom of one to make the top of the stove. It still requires some finesse to get the halves together, just not as bad as the V8 cans. I want to run a couple on some tests to make sure the performance is right before I switch my stove stock over to this method, my observations thus far are purely by sight and not by Thermocouple.

I also don't think the aluminum cans look as cool as the V8 cans righ now.

Major Slacker

Another advantage of the V8 cans for me is that I can scale a stove design to meet my needs. I like to have 3 cups of boiling water -- one for my cup and two for my meal. It can take 1.5 - 2 X the usual fuel to get a boil in cold weather, and if I'm boiling water for dinner or breakfast anyway, I prefer to sanitize water by boiling it an extra 2-3 minutes rather than filtering or chemically treating it. I would want tins that could hold up to at least 1.5 oz.

Right, bigger tins would work, of course.

Thanks for the photos. Looking good.

The action shot makes me wonder if you've noticed any difference in performance due to the Ti-pod acting as a heat sink. It isn't very massive, and it's fully within the zone, so once everything reaches the alcohol flash point there probably wouldn't be any effect. Still, inquiring minds want to know.

Ive noticed that my Aluminum version of the TiPod is drawing alot of heat and dumping it into the ground. I dont have any hardware cloth but I wonder if it would keep the heat dump down to a point that fuel savings evened the base weight out? Or maybe I just need to use ti ;)

you can go to just about any resturaunt and they will give you all the cans you want. I work at one at a fishing lodge during the summers and we go thru cans of every size and shape, this is a good source for multiples of a particular size.

I'll have to try the restaurant/bar idea.

Scavenging cans roadside has significant drawbacks despite the environmental and civic benefits. Then, too, I did find a 5-spot…

SGT Rock

I did notice the steel version of the TiPod acting like a heat sink, it really screwed up the stove dynamics, but since Ti is an insulator, it is very "invisible" to the process. The titanium stove stand is a great change in the system I could never achieve with another material except maybe ceramics.
