making a storm kettle

[brigit]

Hi,

I got a 1 pint kelly kettle for my birthday which is great, but I'd like to find out how to make a bigger storm kettle from reclaimed materials of some kind.

Has anyone tried making one themselves or got a link to some good instructions?

Thank you!

[bigzee]

Hmmm?.....I've never owned A kelly kettle type thing but they seem to be a damned efficient way of heating water. Making one on the other hand would probably be more of a "proper engineering project" than a "cut/drill/bash" garage job. The water chamber which is concentic around the fire inner would have to be made watertight and would require decent welding or soldering of some sort. It might be difficult to recycle existing containers to the required standard for this, but now you've set me thinking I will apply my mind to the task and let you know if any "light bulbs" come on.

[Fletching]

What bigzee says.

The problem as I see it, is that the Kettles you buy are not welded, but shaped and pressed. Even if you find the right shape of containers, you'll have to think about joining methods. I wish you luck on this one. :)

...any engineers on the forum?

Think I might start saving up for the next size up kelly kettle....

[dave budd]

i once saw a large version made from a couple of fire extinguishers welded together. The inside skin was an old fashioned cone version and the outer skin/base (the outer extended a few inches further than the inner and had air holes in it) was a newer parallel sided one. Only trouble with that is it will rust if not put away dry and it's a bit heavy!

If you want a bigger one that is ready made then I got a 5 litre version from Wild Stoves a couple of years ago and it's brilliant :) As for making one, then you could do it from some stainless containers if you can find the right sizes and can hard solder/tig weld well enough. I thought about it myself, but to be honest it would have cost me more in time and faffing (ie swearing) than I could buy one for

I have the large one 2 and half pinter it is great but not if your going for a walk it is best for a base camp :)

[fish]

making one isnt as hard as you may think,you just need a twin walled meel container,i recon one of those all metel vacuume flasks would be a good start as they are double skinned .

[Jack Russell]

NO, no no no no - Brigit I either love you or hate you, I'm not sure which. Did the Sunday market and carboot this morning with the words of the Fish lurking at the back of my swede somewhere. Now's there's a heap of stainless steel double walls on the living room carpet. I've got posh tig welding kit available at work and lotsa nice tools to play with but the challenge for this thread has to be "could I knock one up in the garage/shed/bushcraft hq?". Gotta tell you first impressions upon butchering a couple of all stainless flasks is that even if I achieve it the research and development costs will outstrip the buying cost of a bigger Kelly. If I still worked in the big hairdryer factory for pushing silver birds through the air, it'd be a cinch but armed with a big 'ammer and some pliers and wonky drills (not to mention now being a whitecoat in a laboratory for a yogurt factory instead) Hmmmmmmmmm Brigit I guess the challenge is "how much pocket money can you save each week to buy the bigger jobby against how long it takes the career aerospace engineer to come up with a how-to". Challenge most ungratefully accepted m'dear. Cheers Jack

[paul standley]

Brigit - you have of course (without realising it) hit upon the bushcrafter's search for the Holy Grail, i.e a DIY cheap kelly kettle...!

Like all such quests, said champions are full of ideas and enthusiasm but many have fallen by the wayside over the years.

For anyone contemplating this challenge, I reckon that actually, it only needs the bottom joint welding/sealing etc as the top can be a push on lid with a hole in it to go over the 'chimney'. I terms of operation, this would behave much like a fully sealed kelly kettle.

Good luck anyway Brigit...!

Paul

[bigzee]

I suppose an important question we should be asking Brigit is : "how handy are you with all sorts of tools, and have you any previous experience with metal fabrication techniques? Of course the answer to her question is yes - it can be done, but the trick would be to have such an inspirational brainwave regards attaching the O-plate to 2x open cylinders, to justify the time and effort.

[swkieran]

couldnt you make one out of say an old copper water tank if you cut it up,copper is easy enough to join and make water tight,all our water needs in our houses etc,are furnished through copper.

[brigit]

Sounds like I need to go on a welding course. Maybe I'll start with a rocket stove.....they look a lot easier!

If anyone manages to make a storm kettle PLEASE let me know!!!!

[Adam Savage]

I am still sat at my drawing board on this one. Will let you know if I make headway.

I think we'll have very similar "alternatives" to it, so I don't need to point them out or release any "sensitive information". Have a pile of tin cans, ali, and stainless steel containers, laying about though lol.

[Jack Russell]

I have to say on this one Brigit, having spent three nights tinkering in my lunch breaks (not any of my work time of course) the Fish's idea was worthy of note but the carboot offerings I'm playing with don't hold enough water in the walls. I'm left with the engineer's response which says "why do you need more than you already have?" Given that you have the one pint model off the shelf it seems to me that you have the option of fitting a collar and pot stand on the top and get more bang for your buck by boiling extra water or cooking that way. This, of course would be very easy to do using recycled or scavenged bits and bobs. If I'm sticking to your original challenge of making a storm kettle out of recycled gubbins without buying tools and kit specific to the job................... have to say it's a bigger challenge than even I thought (and I'm absolutely brilliant, the bloke who winked at me while I was shaving this morning told me so). I reckon if Adam, Paul and I hole up in Adam's tidy little bushcraft manufacturing hq for a month we'll be onto something........

[paul standley]

OK guys and gals... let's go back a couple of steps...

How about adopting the key functionalities of the storm kettle BUT.... turn it inside out .....literally.

Key functionalities and principles:-
1. Chimney effect to pass hot gasses through a chimney to efficiently heat up a water reservoir as it passes
2. load fuel from the top down the chimney
3. separate fire box to sit the chimney & water reservoir on top of
4. aperture in fire box to load fuel from the side
5. ability to use variety of combustible materials to hand
6. ability to utilise exhaust hot gases as they exit chimney for secondary heating/cooking

Why copy it when you can re-invent it - think outside of the box, think "Chimney Kettle" not Kelly Kettle and let's say we are going for a 2 pint water boiling capacity...!

I thought about that, but lifting the stove (or even just the water reservoir) while on the go, could be tricky. Thought of some kind of pin running across the neck of the said receptacle, which holds it central in the chimney, as well as offering a mounting point for a lifter of some kind. If that makes sense. LOL

[paul standley]

Yep... you are on the same track as me Adam :-)

[paul standley]

Just seen this... Ronnie Sunshine is doing a 1.5 Litre Ghillie kettle for £49 + £3 delivery...

Never make a CAD operator, but I hope you get the same image as me from it.

[paul standley]

Yep... I see what you see.

What would you envisage as chimney & water reservoir diameters, could you get sticks down the chimney ?

[paul standley]

I'm thinking along the lines of off-setting a water cylinder in the chimney to create a wider chimney aperture down one side to throw wood down and fixing the water cylinder and chimney together with handle on outside of chimney to pick up and pour.

[Adam Savage]

Haven't really come up with a solution myself, but I will have a tinker tomorrow and see what manifests.

[Adam Savage]

Just completed stage one of ultralight storm kettle Mk1.

Next stage is to seal spout and top join of chimney and bottle base, with liquid metal or JB weld. Then construct fire box, before test firing.

[Adam Savage]

Firebox completed. First test showed slight seepage from bottle neck to chimney, so more quicksteel has been rushed in to save the day. I use this as it is drinking water safe and bonds well to ali.

Donor can...

Looking ok I guess...

http://i1024.photobucket.com/albums/y304/crazysaint22/projects%20and%20equipment/02062011739.jpg

Holds 250ml of the wet stuff. Test firing tomorrow. Will keep you posted.

[paul standley]

I'm impressed buddy...

I'll check out the quickseal product, some of the sticky stuff is not people safe so this might be useful stuff.

Looking fwd to the fire up :-)

The only downside to quicksteel is, it's only rated to 260 degrees c, but I'm hoping not to reach that, as the ali won't take it anyway. I found out when I was trying to burn the protective film off the bottle neck. Here's what happened lol.

thats clever adam :),youre quite handy at metal working m8,have you got a furnace you could make mould of the componants you have there, and cast other metals,im in the process of making a copper melting furnace for scrap copper,i will upload pics and tell you how ive made it etc,im having problems with the intense heat that it generates it cracks the concrete blocks and cement im using,so i will proberly line it with flag stones from the reclemation yard

Thanks Kieran. Haven't got a furnace as of yet. Will be interesting to see how you've made yours. The highest resitance materials I've come across are fire bricks and fire cement, at around 1000 degrees C for the cement and 1500-1700 for the bricks. Would they make a better "box" for your needs?

whilst this is a fine design that will work it wont work the same as a kelly as the tapered inside of one increases the draw.

[Adam Savage]

I know, I was just throwing an idea in for the reverse kelly. Shapes and sizes weren't accurate really.

Just test ran the ultralight storm kettle, showing a boil time for 250ml in 7 minutes 40 second, which is pretty poor, even with just a handful of cedar shavings. Waiting for the video to process and then I will post it up.

[Adam Savage]

Here's the video. Sorry it took so long to process. Also forgive the temporary handle effort and the fact I cheated by using a lighter. Also the firebox seems to be a little on the deep side. You'll also notice I had to relight it toward the end. Seems to burn fuel fast. The smoking from the firebox is mostly the white coating of the tin and remnants of wax proofing.

[paul standley]

Interesting video Adam.

Looks and behaves mechanically like a kelly kettle so well done for that but the boil time was a surprise at 7.5 minutes.

Difficult to know why but I'm thinking that it's maybe a question of scale. The fire was pulling well and burning pretty clean so for some reason, the heat wasn't transfering to the water which could in part, be due to the size of the kettle and the resulting short chimney and therefore short contact time with the hot gasses/flame.

Could try a smaller hole in the fire box and move the hole down a bit as well to hold the heat/flame inside a little more.

Might be worth repeating the test with some meths in the fire box instead of wood to get a comparison. The meths should work a treat in this chimney style set-up and it might show up some differences.

Other than that, not sure why it didn't boil faster but great bit of work never the less.

[Adam Savage]

As in a pressurised stove or just an alcohol reservoir type thing?

The chimney is stainless steel, which may be drawing too much heat before transferral.

I have a square firebox I can try on it, giving a slightly wider fire base, along with smaller intake hole/s.

I have something to work with now anyway ;)

Just pour some meths into bottom of fire box, I'd say 30 to 50 ml and just light it, give it a few seconds to warm up the fire box metal then put the water reservoir on top.

[Raven]

hey chaps,
just come across this thread, how interesting, just up my ally, great idea adam, love the vid, what thickness steel is your chimney pipe? may be a factor to consider as well as diameter and length, not to mention ali would transfer heat better? but brilliant build, i'll have to come up with something along the line!!! what fun

paul

[Adam Savage]

It's 0.8mm and it came from a titanium exhaust box, so may be ti, but looks like stainless to me. Just ran another couple fires with meths. First failed due to lack of reservoir capacity. It ran out after around 4 minutes, but the water was steaming when I emptied it so not too far off. Second run, added bottom of lynx can to hold meths. Used hardly any fuel, but seemed to take around 6-7 minutes to boil still. The gap between firebox and reservoir could have hindered heat/energy usage/transfer. Sure it would work better with a little meths around this internal reservoir, to build heat (almost like priming a penny stove) and create more updraught.

Videos are processing as we speak, so will post ASAP.

[Adam Savage]

Ultralight storm kettle, meths run..FAIL ;)


http://www.youtube.com/watch?v=if0e2nBsabo

[Adam Savage]

And with larger alcohol reservoir.


http://www.youtube.com/watch?v=OdjsfyWXTwY

[Adam Savage]

Unfortunately I did slightly over fill the kettle...again...taking 6 seconds to correct, so I guess boil time was 6 minutes 24 seconds. Still quite a long time.

[paul standley]

Adam - Have you thought about slowing down the heat loss up the chimney by closing off the top of the chimney with a restriction (i.e place a small piece of flat metal over it) to differeing degrees, this might reduce heat loss a bit .... A bit like a simmer ring on a Trangia.

Overal, I'm thinking that a DIY storm kettle would come into it's own at around 1.5 pint capacity and above. Less than that and a variety of other DIY stove and pot types would do a better job.

I thought about a restrictor of some sort, but was trying to come up with a "tidy" solution.

The reason behind the size of this storm kettle is it's smaller and lighter than any in production. The 1 pint storm kettle I have seen advertised is 600g, while this half pint (ish) is 248g including firebox and handle. Giving just enough water for a single cup. But looking at the boil times so far, I'd say it was more efficient to use a trangia or pop can stove lol.

Well if you think you might continue with the ultralite kelly kettle then maybe worth trying an ali chimney or even a copper one, if that doesn't work then I'm stumped.

I have been eyeing up an old ali 2c cell torch, which has the same threads as the £1 bottles. May have a crack at using this as the chimney, as the threaded end will give me a good seal at the lower part and give better heat exchange. I'm not overly keen on copper (don't know why really), but could give that a go too. At least I have something to work from and improve on with the Mk1. I will also run a test with the lynx, meths reservoir, but putting a small amount in the main firebox, to help pre-heat. The Mk1 isn't dead yet lol.

[Adam Savage]

Just found out the backcountry boiler weighs in at 225g, so looks like I need to go lighter for my ultralight...Bring on the ali...

[paul standley]

I was looking at an ali hair mousse can today, might suit your mk 1 sizes. Approx 28mm dia and tall enough and thin wall.

[Adam Savage]

I think I have seen one of those at my mum's lol. May head over and pilfer one later.

[Adam Savage]

Just ran another test with meths, this time adding a washer to act as a restrictor and "priming" the reservoir. Boil time came down to 5 minutes 14 seconds this time.
the video is being uploaded as we speak.

Here's my contribution to this challenge - a sneak preview of mk 1 of my Chimney Kettle. OK. it's not a Kelly Kettle but it's based on reverse thinking, putting the flue on the outside instead of the inside.

It's not finished yet either, needs a handle and some refining but essentially, it works...! - here are the stats:-

Based on meths or solid fuel engines (can use various configurations)

0.5 litre capacity, based on on half litre Poundland £1 aluminium water bottle.

Boil time for 0.5 litre of water in the garage averages 7 minutes

The kettle can also carry 0.5 litres of water since the guts of it is a water bottle...! - just fill and screw in the cap.

2 part unit - a) the kettle/chimney and b) the stove base (outer shell base that holds various meths stoves or solid fuel - i've got several types, this is one of the more efficient ones).

Cost was £1 for bottle...! - chimney was a confectionary tin and various stove engines were all made from old cans/tins
Photo's show the 2 parts together and side by side with a 0.5 litre aluminium bottle for scale.

Multiple test runs on the prototype were all good so I'll be developing further and maybe going for a 1 litre wood fired version as well.

I'll post up this 0.5 litre meths version when it's finished with a video and instructions.

Looking good mate. Very clever the way you have fixed the bottle inside the chimney. 7 minutes seems to be the universal boil time lol. During tests with homemade stoves I noticed it was around that for 1 ltr as well.

Ahhhhh but you can Brigit....................... the experiments so far are showing you the possibilities with "stuff" we've got lying around - BUT it doesn't yet address your original question on this thread, ie you want to go bigger than your existing KK. Therefore, it is your task to look for a donor container to be recycled using the research and development that Adam/Paul and the brainpower of Natural Bushcrafters et al. Now that doesn't require technical knowledge, it requires an "eye" whilst shopping!!!!!!
