Hey mate, nice video again 👍 Please READ: Welding over zinc is poisonus. There was as a guy locally that prefered to do auto repaor with zinc sheet metal. He was doing it for years. And now he is no longer with us 😒 So please, do the local cleanup before welding, i would love to see more of your videos as you do a realy nice job 👍
Welding over zinc coatings without proper ventilation is certainly not healthy and can cause an acute sickness called metal vapor fever. It is supposedly severely unpleasant, but it is temporary! But on the other hand there is no reason not to prevent inhaling welding fumes. They won't help you see your grand kids grow up! ;)
Oh my god, I need this one inch steel tubing to put inside a metal drum so I can use firewood to heat up a outdoor tub. 🥲 you’re a legend. Now send me one to the USA.
That's a big commitment to making coils. :) I guess you will be making many more now. Smart move on being the ballast for the test. Work smarter let others do the sweating. I hear you guys are out Boonah-ish way. You helped my nephew Cory with his exhaust. Great to have local talent on RUclips.
I like your way of doing things and sharing your ideas . Definitely worth making a machine mate , only a suggestion but possibly a reduction drive motor
That would just make it amazing. Wouldn't be too hard either as I have a few three phase motors and gearboxes I've salvaged I'll have to think about it.
This is the second video of yours that I've watched, I like the craftsmanship, and also the "DIY friendly" approach. (It's also refreshing, in a world where one AI can handle an entire factory full of machines, to see three humans "dance" with one machine to make it work:) Thank you.
I Love your videos. I wonder if fitting a similar pipe coil into a cylinder with a bottom so I could heat hot water with bbq charcoal for a small hot tub?
grab a diff ;) one axle bolted to the ground, arm on the other, bendy doodad on the crown wheel/housing. you got a 2:1 reduction. used to bend that pipe you got as a solid bar... but then... get yourself the proper wheels. the rollers arent that expensive. or make em. rather than wrap it around the cylinder with the squashing, just roll it through. lot easier. nice fat flywheel (tractor tyre full of water?) driving one roller, and just keep feeding through and squeezing it a bit more. any radius. any pitch... no sand, no sweat. look at a standard ring roller? youre damn keen trying to do it in one pass directly. not sure how you attach at the ends on these, but stainless? i suggest using compression fittings for this stuff. one, old boiler lessons... you wanna be able to clean them out. lot of scale builds up. i have really good water here, and i still get bad scale. it cant be avoided. two. stainless fatigues if its restrained on thermal cycles. stopped making monotubes unless i run distilled water several years ago... the best approach is the radiator type thing, with a LOT of compression glands... old "babcox and wilcock" or "yarrow" type things. even if it isnt boiling but simply heating. large bore upper and lower receivers or headers, and 20 or more straight pipes between in the flue. and only let the thing rest in sockets, no bolts, clamps, tie downs. has to expand freely. i bought a whole bunch of heat pipes for an experiment with them, but yeah... never got around to it. make a "hedgehog" type inner sleeve with an outer jacket tank sleeve thingy for throwing in the chimney of the normal fireplace... copper is so much more forgiving for long term service.
Love it, and please make more of these! Ps: welding galvanised steel without cleaning before is very bad for you. But I guess you know that already. Just would like you to keep making cool things a videos!
I felt like i was caught in a Sergio Leone fueled welding time warp...where am i?😂 great work! I thought that you might adapt it onto a autowheel rim and use the weight of the car/truck/ whatever to help?
….. make a machine that spins this…. Ummm…😳 You’ve got one, it’s called a lathe. 😂 Further, if you attach the follower (bending runner?) to the saddle, you can have auto advance. 👍 I would envisage running the lathe in deep reduction, the arbour held between centres and tubing away from the chuck. It’s how I’ve seen springs and stuff being formed. Anyways, great channel. 👍❤️
In principle I could use the lathe, but the sand getting between the saddle and the weighs would destroy the lathe's accuracy and I want a system that can reclaim the sand. Thanks anyway
Was your mother's name necessity? Great invention mate. I'm the proud owner of one of your little stoves, keep up the great work, wishing you all the best for the future.
would something like a cement tumbler which also can be angled be worth looking at for your sand removal or would something like a large air compressor to blow out the air be the way you want to go?
Ease of manufacturing as a welder, I know it's not as efficient as copper, but I plan on exposing it to some really high heat and copper might suffer if not full of water.
@@LittleAussieRocketsFor some of your other rocket stove water heaters do you think that I should expose copper to direct flame? only if filled with water ?and to what temperature would the tubing withstand? Cheers 👍
Could you put that inside a container...and put the exhaust of say a small engine thru that pipe...and inside the tank have the water...kinda like a reverse heat exchanger I know many small engine exhausts can use 1" or less exhaust fittings so the pipe should be enough to handle the volume of exhaust from a small engine.
All the stoves I make are strictly for outdoor use only. Once you start making stuff to go inside it's a very different kettle of fish in regards to regulations and insurance. So if you want an outdoor rocket stove, it is a possibility if you are in Australia. Please e-mail me if you're still interested. Cheers. littleaussierustics@gmail.com
Nice work Steve! I expect that if you are going to make any more 25 mm s/s pipe spirals that you will utilise some of those electric motors and gearboxes that you mentioned having. A metal internal spring like electrician's use, should be faster and easier than the sand method. Watching the piece of timber on the lathe was wild especially the way it seemed to twist like a aircraft propeller. Is it still just the three girls that you have? I wasn't sure if I missed one arriving. 😂 Mark from Melbourne Australia
Hi Mark. Yeah when I played back on the camera I couldn't believe what I was seeing. I just happened to fluke the right shutter speed that matched the RPM of the lathe. And yes, we still have only the three girls though I keep joking to my wife that there is still more seats left in the minivan and I'm happy to do my part 😅
@@LittleAussieRockets I can only guess what your wife's response would be like! Actually, check out the child assistance because from memory, three kids was the worst position of all, whereas four and beyond gives extra support. That was quite a while ago so check out the facts before you do anything! Mark
@@LittleAussieRockets I asked one of the science teachers at school about the effect of seeing aircraft propellers changing their apparent direction on film when the revs are changed and he said it was quite a complex topic given the refresh rate of our eyes, the shutter speed or frame rate of the camera and the revolutions of the propeller(s). In a similar vein, I was watching a English farming show and they were attempting to show how the chickens reacted to aerial and then ground threats. With the ground threat they used a stuffed fox and the chickens didn't react properly because they have a higher eye refresh rate than we do and they could instantly see that the fox was not moving correctly. It was all to do with their higher speed vision. How are the chickens going in your coop? Not the ones who go to school! Mark PS just saw your new forklift short.
No I haven't worked with salty hot tubs. $800 is pretty expensive, I imagine he's getting them manufactured through a third party and I have no idea what they're charging to do that. The rig that I built to make my coil might be your cheapest option if you're that way inclined. There would have to be someone out there who could manufacture a coil for you locally. But if you want to make the coil I would go with copper pipe, a little bit more expensive but easier to work into the desired shape. It just needs to be filled with sand and the ends hammered over so that the pipe doesn't crush. Hope that helps.
G-Day Mates, Long Time No See Y'alls? You've Been Too Busy Makin Babies & Not Workin Hard Enough? I Like The Way You Used Your Wife As Dead Weight On Bender Table... 🤣🤣😁😎
@@LittleAussieRocketsHi, I don't mean to butt into a convo about something else, but I wanted to respond to you directly rather than take my chances leaving a comment on a 10mth old video. In regard to the sand removal, assuming you haven't already found an easy and efficient solution, and assuming the sand is not bone dry and can be simply (but messily) blown out with compressed air, why don't you simply wash it out with water? Stand the coil upright, make a hose fitting that's watertight, hook up a hose at the top and a filter to catch the sand at the bottom, and leave it to do its thing while you do something else. That's my rough off the top of my head farmer solution. I'm sure if I have 2 or 3 ideas to do that job, you'll have 10 or 15 you can come up with that are a bit more sophisticated but efficient from that lol
Great seeing your beautiful wife helping in this video. I have a machinist friend that uses coiled steel springs inserted in copper pipe in place of your sand. I’m not sure where he sourced his springs or how long they are but I can ask if you are interested. Will your be compressing the loose coil or two down into the stack? On The Outsider, another RUclips channel, a Canadian used a copper coil that was inside a kettle of sand to heat water. The sand acted like a heat battery that continued to transfer heat as the campfire burned out. The thermal siphon was used to heat water to keep his camper sled warm during winter nights. (ruclips.net/video/x82KFhfbbBU/видео.html) Wishing you and your family a blessed week filled with gentle seasonally appropriate weather and restful evenings together. Peace brother
That's a cool video. Thanks for sharing it. You've got me thinking. 👍 And I would be interested in the springs. I have seen something similar used by electricians when bending PVC pipe. I imagine it's simla. Perhaps more heavy duty though. Always lovely to hear from you. I hope you have a blessed week 👍
@@LittleAussieRockets I have texted my mechanic / machinist for better description of the springs and where they were purchased. I will forward all info to you when it arrives. Until then, remember to be good to your self and yourself... Peace brother
@@LittleAussieRockets I doubt it would be convenient without some specialized equipment, but one episode of "How It's Made" showed a trombone manufacturer using ice with some soap added before bending.
I owe you an apology. I had the sequence wrong; my friend advised that the pipes to be nene are places inside snug fitting steel coiled spring (think overhead garage doors) and then bent. These coils are purchased from local big box lumber & hardware stores.
We are so lucky to be in an age where I can observe such skill, "first hand". Thank you so much for this walkthrough!
Nice easy watching with no talk.
Just awesome.

At the beginning, when you were welding the tabs on the pipe, I was thinking to myself, "Is he building a rocket?"

Looks like you need to flip that contraption upside down on some sawhorses and fill the base with concrete. For ballast.
I Love your videos. I wonder if fitting a similar pipe coil into a cylinder with a bottom so I could heat hot water with bbq charcoal for a small hot tub?
Welding Gal? Hope there was some good ventilation there mate!

Yes I have a large exhaust fan and I would stop after a couple of welds to let it catch up. Thanks mate
Very cool. Love the vid. Your machine for emptying the sand - slow rolling with a vibrator on it would probably work
nice helper!
grab a diff ;)
one axle bolted to the ground, arm on the other, bendy doodad on the crown wheel/housing. you got a 2:1 reduction. used to bend that pipe you got as a solid bar...
but then... get yourself the proper wheels. the rollers arent that expensive. or make em. rather than wrap it around the cylinder with the squashing, just roll it through. lot easier. nice fat flywheel (tractor tyre full of water?) driving one roller, and just keep feeding through and squeezing it a bit more. any radius. any pitch... no sand, no sweat. look at a standard ring roller?
youre damn keen trying to do it in one pass directly.
not sure how you attach at the ends on these, but stainless?
i suggest using compression fittings for this stuff.
one, old boiler lessons... you wanna be able to clean them out. lot of scale builds up. i have really good water here, and i still get bad scale. it cant be avoided.
two. stainless fatigues if its restrained on thermal cycles.
stopped making monotubes unless i run distilled water several years ago... the best approach is the radiator type thing, with a LOT of compression glands... old "babcox and wilcock" or "yarrow" type things. even if it isnt boiling but simply heating.
large bore upper and lower receivers or headers, and 20 or more straight pipes between in the flue. and only let the thing rest in sockets, no bolts, clamps, tie downs. has to expand freely.
i bought a whole bunch of heat pipes for an experiment with them, but yeah... never got around to it. make a "hedgehog" type inner sleeve with an outer jacket tank sleeve thingy for throwing in the chimney of the normal fireplace...
copper is so much more forgiving for long term service.

Hi there I liked how the wood in the lath went candy striped due to the shutter speed of the camera
For draining the sand, can you have it upright and vibrate it with jigsaw or recip saw?
I always love your content!
God bless ye merry gentleman.
would something like a cement tumbler which also can be angled be worth looking at for your sand removal or would something like a large air compressor to blow out the air be the way you want to go?

Any particular reason why you've opted for stainless steel over copper tubing? Looking forward to seeing the completed unit.
Ease of manufacturing as a welder, I know it's not as efficient as copper, but I plan on exposing it to some really high heat and copper might suffer if not full of water.
@@LittleAussieRocketsFor some of your other rocket stove water heaters do you think that I should expose copper to direct flame? only if filled with water ?and to what temperature would the tubing withstand? Cheers 👍
You could try using a vacuum cleaner. A clean one of course this way you can recapture the sand and use it again
Thanks, I will try that next time.
Could you put that inside a container...and put the exhaust of say a small engine thru that pipe...and inside the tank have the water...kinda like a reverse heat exchanger
I know many small engine exhausts can use 1" or less exhaust fittings so the pipe should be enough to handle the volume of exhaust from a small engine.
looks good mate copper be easier

Might I make a comment that could make it easier to use mount a chain gear for using a motor to turn it for you

As he replied, the stoves are outdoor only, but I’ve seen a few tiny houses with little stoves mounted outside to heat water, always an option.
@@LittleAussieRocketsI would only use a rocket stove externally, some distance away, with appropriate hoses and connections. I'm in BNE.
you could achieve a better result if you used a better formed die for the pipe when coiling and using water instead of sand to fill the pipe with.
В трубі пісок засипаний?
Yes 👍
Does that fit snugly over a standard 150 stovepipe ?
It would be very close, slightly bigger
if you heat the pipe - it will be easier to bend

How do you adjust the pitch of the coil?
It's all done by hand, as you go around the guy supporting the pipe holds it at the appropriate height to create the pitch you're after.
