hobo esbit stove (fail?), and some time outdoors

I managed some time to get out of doors (admittedly not as far out as I'd like to have gotten), and thought I'd share some pics.

I took the pup and hit the river for some fishing, and decided to take along my attempt at a cheap (free) esbit fuel stove for a trial. The stove is small by design: sized to hold and heat the GSI nalgene SS cup and fit into it for storage. I made it from a condensed milk can. I drilled 5/16" holes around the base and top. The fuel stand is a scrap piece of stamped aluminum (steam) radiator grille material. I set the tab of fuel in a foil "cup" of sorts.

The days lunch menu: granola bars and some hot tea. For this first test I figured I'd use up some broken esbit pieces for my fuel. I used my firesteel and a PJCB to light the fuel tab. I didn't catch a pic of it, sorry. It worked well though, even in the 25mph wind gusts we had that day!

The little burner held the mug nicely, was easy to light and the fuel burned hot and fast - TOO FAST, I think. This is where I failed, I got no boil when my fuel was gone! I think if the wind was less fierce and I had a solid single full Esbit fuel tab, it would have worked better. It gave me enough to steep my tea, though I'd like the burner to be able to heat some Ramen on a single fuel tab:

I'll have to work on the fuel/air ratio and re-test with a solid tab. Maybe I will need to adjust the height of the fuel as it burns relative to the bottom of the cup. I may also add a windscreen to it. I still want to fit the cooker, screen, and some fuel tabs inside the GSI cup so that it remains a small, handy stove.

Anyhow, here are a few more shots of the day:

that's it, no fish to show off this time.
 
nice...

my brother just got me that GSI cup for my b-day yesterday... i asked him for the primus eta express :D :D :D but i was just kidding and told him where to get the GSI cup for 10 bucks... i like it how it holds way more than 18 ounces... i poured 24 oz yesterday and it looked like it could hold abit more...

I am trying to do the same thing as you... but with an alcohol stove i made a few weeks ago... the stove burns pretty hot for about 6 mins with 1 oz of denatured alcohol... brings three cups of water to a boil in 4mins... and it holds about 2oz...

I hope to get my setup by this weekend and then i'll show you guys some pics...

Looks like a handy little cooker, If it was a little larger and you ran out of fuel you could actually just use some fine kindling split up with a knife.
Thanks for posting,
Gabriel.
 
To help with the esbit, I agree with the post above mine. Some small twigs would help it burn just a little longer. At least enough for a good boil.
 
It does look as if the height is too tall for the Esbit's flame to be a maximum efficiency, so I think you're right that playing around with how close to place the cup above the fuel would yield better results.
 
about scout... i like her... i think i am getting a beagle for my wife... she likes them too!!!
 
i just finished my hobo stove with the GSI mug... but i don't have a camera to take pics... :(

I'll post them later...
 
i think i have another theory on why your esbit did not heat up your water to a boil...

I just finished my stove and tried it and the alcohol stove burned for like 10 mins... and the water never was close to boil... i was surprised at how long it burned for...

I removed the wind screen (was to tight i think and not enough air was going through) and then water boiled in 3 mins and the stove burned for 6 to 7 minutes...

I don't think enough air is going through your stove to make it burn hot enough... Just a theory...
 
That is a good link! Thanks for sharing.

I tried another can last night in a hurry - a shorter wider can and burned 3/4 of a solid tab. I originally thought the tab was set too far from the bottom of the cup so I burned it with the tab higher up....but I found that with the same amount of airflow holes in a still air, the tab extinguished itself about halfway through. I then took the tab stand out of the can and burned the rest of the tab just on the bottom of the can (about 1.5" below the bottom of the cup, and it burned with much more vigor....but still didn't boil the water after a total burn of 14 minutes.

I will re-read that article and get some fresh fuel tabs and make some changes...but right now it seems I'm better off sticking with the surplus german army folding esbit stove! At least I am experimenting with cheap materials for all these new stoves!
 
Thanks for the lesson on stoves. I've always assumed that the higher was better up to some limit, but hadn't tested. Good job Britch.

you should experiment with alcohol stoves... they are fun to build and cheap... they will burn two cups of water in 3 minutes or less...

I'll get my camera and post pics on a new thread probably tonite... I am getting the camera tonite :D :D :D
 
Good thread & great looking pup !

Thanks! But I must confess...she's not a pup anymore, she's almost 4! I just think she still looks like a pup because she stayed small (~22lbs) for a Beagle.

I suspect I'll spend some time in the backyard tonight trying out different stove combos...

as for the alcohol stove; I've been thinking about making one, but I like the idea of solid state fuel for packaging and transportation....with a small esbit stove, I figured that I can also make a quick cup of hot tea or lunch in the blind if the fowl aren't flying on a given cold day.

yeah.... the esbit cubes are very compact... but not as efficient as the alcohol stoves... I really need to post pics :D i'd like to show you what i built...
