Coil Stove, as promissed...:)

[lannyman8]

Well, i have been toying with making a coil stove for some time, i went on the evil bay and got some 6mm anealed copper pipe, and some JB weld quick set heat resistant resin.

i knew what i wanted to make, a meths stove that boils fast, with little or no pre heating needed as with coke can type stove..

this is for walking days when i just want hot water fast for brews, and dehydraited meals.

i have not started her up yet as the glue is still cureing... all i need to do is make a wind shield from a "BIG" bean tin and jobs a fish...

the whole thing is made from the copper pipe, a nut and bolt which formes the filling hole, so it can be sealed after filling, and 2 tuna tins pressed together then glued, the pipe is a bit iffey as i dont have a pipe bending tool, bit of glue and your away...

hope you like it anyway.















comments welcome as always....

looks good but how does it work ?

 

[lannyman8]

the bottom of the coil has a jet hole in it, you light that hole which heats the copper pipe, that causes pressure which can only come from the hole so forms a constant loop, bit like an oil drum charcoal kiln...

Would like to see this in action. Not an idea I've seen before. Interesting...

i need to see this lit to get my head round it Chris, is it only a single "jet" of flame that comes out of the coil ?

 

[lannyman8]

yep, single jet, you can see the very small hole in pic 2, its very high pressure and burns like a blow torch, the glue is still curing but will try and post pic's 2moz...

interesting looking stove lanny, maybe keep a bit of a distance the first time you light this one up!

i like it Chris, i'm thinking of the Swedish army cookset, would it sit in the bottom of one of those ?

 

[lannyman8]

like this dude http://www.youtube.com/watch?v=3Bl0Yr_wS0U

it could be made to any spec, i was going to use coke cans but the Mrs keeps squashing them...

the base of my one is a tuna tin size but anything would work as long as its sealed....

 

[Robbi]

WOW ! thats a jet engine !

 

[lannyman8]

good stuff ehhh......

its light too, should be ok ish on fuel aswell, im going to try it on kero at some point in the future...

Looking forward to seeing it in action, how do you prime it?

Mate!! i,ve had close up personal experience of one of Chris's ,...erm....."pyrotecnic incidents"

his invite of,... "its my birthday, come round for a beer!" led me to believe a glass or two in a civlised enviroment,....

the ACTUAL experience was WAAAAY different,....

long story short,...i have shrapnel in my left buttock (not an exageration)

hahaha whens the next BBQ buddy??

sorry to drag you thread sideways,...but youve obviously had the white labcoat on again ,..i,m keeping well away from this one!

Stu,..

looks like a very nice stove, I seen similar made with a jar befor, I have also read somewhere "if you put a wick inside the pipe it will improve its burn time and make it hotter" im
not sure how true this is as i have never done it, good job mate

It's very nice but the filling point looks slightly obscured by the coil - making it further from the centre would make things easier, wouldn't it?

How is the nut attached - rivnut?

 

[Chiseller]

If yours works Chris....reckon tha outa clear yer inbox

Fear the men in lab coats.....

 

[Elines]

interesting - how do you put it out once it is lit - in the video it seems to just stop for no apparent reason.

The flame is impressive but what is the advantage of this design - does it boil quicker on less fuel (for example)

 

[spandit]

Also, how does the fuel get to the hole in the first place? Is there a wick or do you just tip it?

Nicely done, will be making one of them shortly
