Backpack Stove Part 1 of 2

[maxinpains]

how long is this can stove would last with every day use?

[wa7mlh]

@maxinpains

Probably a few months, at most, is my guess.

A lot depends on how much heat you try to extract out of it.

The can is steel, so that is a plus.

Also depends on how much you let it rust (or not).

@ferdinand7004

Ahhhhh....OK I understand now.

Well, I would only use this in a wet setting or when it is cold and on dry dirt.

The distance from the tent walls would be enough that there would not be any fire danger if the

stove did "fall over".

[wa7mlh]

@ferdinand7004

If it is windy enough to flip my tent over, I would not be running any sort of stove.

And I would certainly shut this one down long before it ever got windy enough to tip over a tent.

This is intended to be used in a Black Diamond Megamid with a 1 foot siltarp extension.

Hard to tip over unless the wind gets really bad.

2:16 - how did you silence her? Be safe and thanks much for sharing :-)

[wa7mlh]

@xexorz

Well, if I told you I would have to ....(just kidding).

She did manage to finally catch her breath after I decided to put stuff back together.

She was sitting near the table I parked the camera on when all of this was happening.

I had no idea that her laughing would be part of the video and saw no need to try and edit around it.

All this survivalism,

Marshall Mcluhan said we were going back to tribalism.

Interesting stuff

[wa7mlh]

@rklcardinal

I have read a bit of Mcluhan...back in the 70s.

Interesting that I have forgotten the tribal concept.

I still think of him when ever I see a TV commercial...or even TV for that matter.

I yearn for things tribal.

[rbow71]

Great vid!!!!! But your wife laughing Made it real!!!!!!!!!!!! My wife laughs at my inventions too!

[wa7mlh]

@rbow71

Yes, she did add a certain ambiance to the clip.

She does find some of my cluelessness to be entertaining.

[goldenscales]

As much as I applaud your good idea, I feel a bit twitchy about the notion of it being inside a tent. Have you done that yet?

[firetecher]

@goldenscales :

I have not done the tent test yet. I am close though. The humidity here in Oregon Cascades is high enough I am not worried about the stove in it. A long enough stove pipe will be cool enough as it exits that all should play well. I will post when I get it to fly, hopefully in the fall of 2010.

[dirtTdude]

if your tent burns down, is that an open fire?

[MOUNTAINOUS]

great idea

[strawalker]

You're nuts dude. Cool though.

[PHARRAOH]

pretty damn cool but too much bulk for my pack. im doing the pct in large sections

[JasonKlassenMusic]

the lady is crackin me up. lol.. I'm confused can you do a video adding your stove in a tent scenario.

[wa7mlh]

A real life tent scenario video is on the list of things to do while the weather is still wintery. I have two different tents I want to try it with. Will post as soon as it happens

[borderraven]

As the exhaust duct heats up it will keep the air moving up. Two or 3 wire guy lines and stakes will support the flu. Be careful about carbon monoxide poisoning in a waterproof tent.

[wa7mlh]

Good points. The tents I plan to modify for this are well ventilated.

I plan to use at least 3 feet or 4 feet of vertical pipe for good draft.

[coreyfmiller]

Well done, I tinker with this kinda stuff myself. Cheers and good luck with it!

[kc7fys]

Well, you could just put it in the back of your SUV--which I'm sure will also fit in that pack of yours.

Nice video, sir.

[safeway56]

He wandered over past the camera and suddenly his wife went quiet. Did he knock her out for laughing at him ?

[DigitalCard]

I like the laughing wife...lol she's makes me laugh too.

[wa7mlh]

Well, you and everyone else who has seen this found my wifes cackling a lot more entertaining than the stove part!!!

[sharkjerky]

backpack stove? how big is your pack, just kidding. WOW!

[wa7mlh]

Actually, my pack is a bit larger that what I see other people carry.

So this stove size does not bother me for a short hike, like under 5 miles or so.

[fegman]

if you do get it right, please tell me, as I am running out of options and tearing what's left of my hair out my friend!

[fegman]

Hello, like what you are trying to achieve, as I have being trying to make a lightweight internal tent stove for a couple of years now, with very limited success. In this case, try using a narrower bore pipe, as the duct pipe bore is too big in proportion to the small fire box; alternatively a larger fire box, as in your case the draw of the chimney is too great sucking your flames up the chimney, meaning the fire isn't heating anything you are cooking, just heating the chimney. Good luck!!! lol

[wa7mlh]

You are quite right on the physics of it as it is.

It was mainly an experiment to see if it could work at all, which it did very well, relative to my expectations. I zorched some aluminum ductwork very quickly.I was trying to save weight. It needs steel. Maybe I need to add a damper to the outlet of the stove. That could/would solve the "over draft" problem. For my needs, I do not need a larger fire box, yet something a bit larger would be nice.I will post further progress.

[gunsup851212]

thats pretty cool, i was thinking of making a small stove myself. thanks for the video

[rwrp]

Do you use a canvas tent? Or a floorless tent like a kifaru. Else, how do you prevent it from melting the floor?

[wa7mlh]

I have a number of lightweight back pack tents.

My plan is to hack one to adapt it to this stove or to add on to one so that I can accomodate the stove pipe.

[highmountainclouds]

Nice invention but not very practical.

[girlinvisible12]

Please place this product at REI.

Marketing hype:

"Made in America"

"Organic"

"Italian Silk"

[cusitoloco]

hope you don't hit the woman when she laughs and you stop the film twice. joke.

[gentiangiant]

Im a chimney sweep so I really got a kick out of that.

[Wartsilapower]

Make sure youre stove pipe is not galvanized as it gives off deadly gas when it gets hot enough.... Nice rig!

[wa7mlh]

I baked off the zinc on the galvanized pipe on a small fire (at a distance in the open)before I actually used the pipe. Good catch.

[eimac4x1]

Thats a pretty good idea. Dont ya just love those pampered chef can openers?

Now if you can devise some sort of thermopyle to couple to the stovepipe, you could run a QRP rig off the same fire.

[wa7mlh]

Yes, the pampered chef can openers are truly awesome. And I am in pursuit of some Peltier junctions for just that idea. I know a guy in Idaho who built up some for his wood stove to successfully charge batteries.

[starwave1967]

lovely buddy, i plan to make one. hay, i like you garden,

thanks
