@Frank Blackcrow i freguently make parts like these by melting down pop cans in a iron skillet with wood and hair dryer and cast them with sand and styro foam, then machine them down with a corded drill and some old screw drivers. This can certainly be done with scrap and house hold materials
@Frank Blackcrow except im poor as dirt and everything i use is scrap like literally my forge is made from a tire rim no plaster or anything everything i use is literally things most people would find around the house and if you aint got a tire rim you can just dig a hole in the ground and use that dirt is a great insulator i see what youre saying but if you put some time and effort into it you can do every bit of that with scrap :)
I must have missed the part where a turbine was made from scrap. CnC machined end caps and rotor hardly count as a scrap built turbine. Nothing wrong with a well made turbine from machined parts, just the title was a bit misleading. I wanted to see someone cobble a turbine together from a tin can, four broken pencils, and a 350 small block. Now that would be some good utubez.
+Tyler Hopaluk They were scraps from another project. Scrap does not equal junk. A scrap piece of exotic hardwood is still exotic hard wood. It's just a leftover piece.
Good stuff. Just note that when you connected two of them, they will both go at lower velocity than if you only run 1 of them. It's not that the first one is wasting any energy. The flow has no where else to go, but when you have a second turbine, there's 'back pressure' which cancels out with the original pressure, etc. etc. So I don't think that running 2 will allow for more total torque, and it's not the same as having a two-stage turbine. Nonetheless, the turbine appears to be very efficient and well built.
Thats true. I think running them in parallel rather than series should provide a true doubling of output without loss. In a closed system where say steam is leaving to be condensed you would want a smaller compression ratio, which I believe parallel inlet and exhaust would also accomplish.
I like your rotor, I have built three steam turbines and 'am planning a 4th although the 3rd one works great for over two years now for off grid electricity generation.
have to ask. have you any data on variable orifices, adjustable position of jets? perhaps some measurements of internal pressure gradients as changes are made ? planetary gear coupling to reduce speed and increase usable power? have you seen the air bearings? a graphene (sic) porous practically frictionless bearing material? lastly where do you show the fabrication of the different rotors ?
make a jet engine out of this and make the turbine as the turbine that drives a compressor. I’m not an aerospace engineer to predict the outcome but it sounds like it’s a fun build
This is actually really funny because the place i work, is a room 2.6x2.6m so it shouldn't take more than 30 seconds to do a tour! If you wonder though how i made the parts for these turbines, i went to a CNC machining shop to make them;)
Just curious, what happens if instead of blowing air into the turbine, you suck air through the other end? Like with a vacuum cleaner. Would it still work and what would the rpm be?
"How to improvise a steam turbine from scrap steam turbine parts." In all seriousness, that looks like a great design. But not exactly from scrap, is it?
Depends what one means by 'scrap'. Domestic scrap, no. But the materials for parts like this can easily be found in the scrap box of even a small machine shop.
You never stop amazing me, do you sell your turbines or is this just a hobby. Don't think I could make one even with the instructions but id love to own one.
what do you plan on powering with the 2 PTOs (power take off) ? you said the original used to much air so compounding them will gain .33 (or the efficiency of your design) of the remaining power per stage could this handle steam ? What wattage generator could this run? I'm thinking high pole count Brushless out runner maby 600w at 90psi. what is the pressure drop across each turbine? like someone else suggested run the sequence in a B. A. configuration, it could improve the over all performance. grate job on the build from blank parts, drop stock😉. If you have access to a CNC machine its just , feed the machine and hit print ... If you have a makerbot then you just hit print. kool work.
Ingenious. thanks for the inspiration friend. Question: does this design provide more torque than a tesla turbine? You said it was difficult to stop part way through the clip so I got to wondering. Cheers W
Certainly you can; but the nozzle is supposed to be built into the housing; his test nozzle is on the air blower tool he's using. And of course; the max. horsepower output point of this type of turbine is apprx. half of it's free speed. If you built an alternator to operate at 26,000 RPM; which is quite possible; it should be workable. Obviously the installation would have to include automatishut-down in case of load dropping; running free the speed would probably damage something. Ceramic ball bearings are available nowadays that work very well at 26,000 rpm.
+johnnyq90 i wonder if you could actually make 2 of those steam turbines and basically connect them together and blow some air in them, and quickly close up the tubing to see it they would infinitly spin since they would spool and keep getting air from each other...
+Marijana Brezić Leave that problem alone unless you want to finish on pills. How about this one. If a item stands in front of a video camera and behind it there is TV monitor showing what the camera shows, and all is lined up perfectly, then would quickly taking away the item, mean that the monitor will show the item without the item being there? These are problems to elevate the human spirit but never try them on a practical basis as they will eat away your time.
+Carmel Pule' ...they will eat away at you, or you approach these questions using maths and you quickly arrive at the correct answer - what would happen if you actually tried it: Original question - as others have said, mechanical losses quickly slow both down to a stop because there is no input. Your question - it's a loop. Even if you assume the time taken by the loop is infinitesimal, this is only an perplexing problem if your brain has imagined that some system-governing principle ceases or changes as the object moves out of the screen - no, nothing would be left on the screen no matter how the question is posed.
Actually due to the fact that i don't have a boiler for this turbine my next project with this one will be a turbine powered tool (a drill preferably). A boiler for this turbine will not be very cheap, it needs to be quite large and powerful...
***** Did you check prallpratte's (google youtube and his name) channel? I remember sending you his way. He does really cool things with steam and rc. You won't regret it. Also, if you can, you could acquire a steam engine and boiler off of ebay. You know those steam toy/didactic engines. A lot of them go for dirt cheap because either the engine is busted or the boiler is broken or missing parts or rust or whatnot. But IMO, for you that shouldn't be a problem since you clearly know how to make your own engines. Cheers. I'm looking forward to the turbine tool.
Hi johnny I was amazed by your videos regarding the steam turbine especially the turbine drill and I wanted to build one for our project but the scrap material you used to build the turbine is hard to find so we will try to fabricate the parts so I was hopping that you could give me the dimension of the parts hat would be great
The rotor i'm sure it's balanced, the noise you hear comes from the bearings... I need to change them but i'm not sure whether i should go for full ceramics or hybrids...
telefon72 there is no perfectly machined disk thats balanced. Just like turbochargers, if you dont balance the turbine wheels, they dont get top rpm to build boost efficiently also they cause major wear in the bearings just from a short run.
Hi Johnny. I want to congratulate you by the steam turbine project. It was the best video I've seen so far .. Very whimsical in building it…. Much like the dental turbine I worked for 40 years. Kkkk. Excelent idea. I'm thinking of making such a turbine to drive a 2.ooo Watts electric generator. But I am not aware of PSI capacity that needs to be injected to get enough torque to rotate the generator. Do you have any experience with this detail? To generate PSI I am thinking of a steam boiler and after cooling the steam that goes through the turbine make it return to the boiler. Great idea to also couple more than one turbine in the circuit
I honestly believe you skills should be utilized for more than just a hobby. You must get tired of hearing it. The idea is easier to manifest than it sounds. You uploaded 48 videos that proves you are inches away from success.
Dude by that definition standard of scrap material, your crappy car must be a Rolls Royce.
Yeah because scrap materials generally include specially machined end caps and turbines with a 0.1mm tolerance....
ROFL.
But perhaps the machined parts were made form scraps from some other job? Who knows?

Well... these could be scrapped pieces from another build that didn’t pan out..
Oh damn! Can you hear how those turbines just sing? It's amazing!

Very nice work sir. This steam engine looks and runs great.
nice,it would have been great to see what happens if the new turbine is first and the one is second.
Perfect Twin Turbo ! beautiful job..
.
As always, just great!!!!!!!!!!!!!!!!!!!
zo zie je hoe eenvoudig het is om zelf iets in elkaar te maken
leuk om te zien
Ahhhhh love youuuu.. Have been suffering youtube to understand turbine for an hour... And you just made it clear😘😘😘😘
have to ask. have you any data on variable orifices, adjustable position of jets? perhaps some measurements of internal pressure gradients as changes are made ? planetary gear coupling to reduce speed and increase usable power? have you seen the air bearings? a graphene (sic) porous practically frictionless bearing material? lastly where do you show the fabrication of the different rotors ?

Great work as always, please do a tour of your workshop (where ever you build your stuff).
This is actually really funny because the place i work, is a room 2.6x2.6m so it shouldn't take more than 30 seconds to do a tour! If you wonder though how i made the parts for these turbines, i went to a CNC machining shop to make them;)
***** ahhh right I expected a small workshop with some small machinery, did you do the CNC yourself or pay for it to be done?
Beautiful engineering, very very nice & well done!
Just curious, what happens if instead of blowing air into the turbine, you suck air through the other end? Like with a vacuum cleaner. Would it still work and what would the rpm be?
+JWC2490 It would still work, but with much power rpm.
+johnnyq90 *lower*
+johnnyq90 Where did you get the turbine wheel?
+johnnyq90 could i buy one of these turbines off you? what would the cost be in USD
I love the noise it makes 😍
3:05 nice sond

Depends what one means by 'scrap'. Domestic scrap, no. But the materials for parts like this can easily be found in the scrap box of even a small machine shop.
Have you tried to use this kind of turbine putting the rotor connected to the crankcase by poly on a gasoline engine or RC engine?
Damn, nice work with making the parts so nicely assembleable I wish I had the means of making something so badass
Use some sandpaper and a drill to make the copper pipe shiny ;)
Awsome turbine!
Well i did it before and after soldering the inlet and outlet, but for some reason it didn't last very long...
How many rpm's do you get from the new turbine after using waste air from the old one?
Could you repair a damaged Pip-boy?
Thomas Samoht Erin’s mom in vault 81 can
You can make a new one
Interesting concept to stage the simple turbines; probably practical; especially with steam.
Very neat job
Now all you need is a little bit of re-heat between those two stages and you have a Thermodynamics students' dream toy...
dude can u please share the cad design of this or atleast the dimensions.its a great design. i would like to use it for my clg project
Now we need to see a 6ft diameter design
is there anywhere where i can find a detailed way of building a steam turbine?
Your brain is a good source
How much power does it produce? What good is it if it's only a toy?
where can I find the outer metal caps and the turbine wheel? would be really helpful
nice build
As always, a beautiful job.
Congratulations! Very interesting that the placement of two turbines in series.
Leandro Wagner.
Thank you Leandro for your comment;)
leandro mito
What do you suppose (or have calculated perhaps) are the power ratings of this device? Do you have the performance specs?
+Breandan McEwen Very similar to this ua-cam.com/video/jejCxvaMKGA/v-deo.html
+johnnyq90 Awesome! I've been watching several of your videos. Nice work man.
What type of bearing does the shaft ride on?
What is the maximum power can obtained from this turbine?
+tarig hamdto A small fraction of the power supplied to the air compressor:)
Good job.
Do you ever sell any of your stuff?
Hey Johnny I was wondering if you could show us how you cut the turbine wheel?
Well done
You never stop amazing me, do you sell your turbines or is this just a hobby. Don't think I could make one even with the instructions but id love to own one.
Can the turbine driven by exhaust gas from 100cc motorcycle?
Hi, is there one for water pressure?

How did you machine the turbine impeller?
Ingenious. thanks for the inspiration friend. Question: does this design provide more torque than a tesla turbine? You said it was difficult to stop part way through the clip so I got to wondering. Cheers W
Do you think i can run this at 160 PSI ? cuz i think it would work but will it shatter the bearings?
Nicam16 I think you just answered to your question ;)
Wait what? Oh darn never mind nice to see ya johnny :D
Certainly you can; but the nozzle is supposed to be built into the housing; his test nozzle is on the air blower tool he's using.

Ceramic ball bearings are available nowadays that work very well at 26,000 rpm.
I would not want to be in the area if you try that at 160 psi
that was so awesome. I'm amased at the simplicity of the engine. Do you think that all turbines have the steam running through the whole inner body?
HalfKaztBoy Yep. That was the plan from the beginning of this particular build...
+johnnyq90 i wonder if you could actually make 2 of those steam turbines and basically connect them together and blow some air in them, and quickly close up the tubing to see it they would infinitly spin since they would spool and keep getting air from each other...

***** considering to my thinking, air wouldnt be able to escape from those turbines or even the tubing, maybe hose clamps would help
Beautiful craftsmanship sir!!
I want to build a working model of a rocket engine turbo pump powered by steam. Might use this idea for the turbine instead lol.
Interesting. So, any project in mind for either of these? Steam car, steam boat???
Actually due to the fact that i don't have a boiler for this turbine my next project with this one will be a turbine powered tool (a drill preferably). A boiler for this turbine will not be very cheap, it needs to be quite large and powerful...
***** Did you check prallpratte's (google youtube and his name) channel? I remember sending you his way. He does really cool things with steam and rc.
You won't regret it.
Also, if you can, you could acquire a steam engine and boiler off of ebay. You know those steam toy/didactic engines. A lot of them go for dirt cheap because either the engine is busted or the boiler is broken or missing parts or rust or whatnot. But IMO, for you that shouldn't be a problem since you clearly know how to make your own engines.
Cheers. I'm looking forward to the turbine tool.
Do you have the CAD drawings for this design? I would love to make one of my own.
what happens when you hot steam though it?
Have you tried making a Telsa Turbine?
the way you made it its so beutifull, you can try for a tesla turbine, its very efficient, 97%. hope to see the tesla turbine next in your vedio.
Can I use this product with water ?
Nice! Great sound...
Where can i buy this steam turbine !
Amazing!
Hi johnny I was amazed by your videos regarding the steam turbine especially the turbine drill and I wanted to build one for our project but the scrap material you used to build the turbine is hard to find so we will try to fabricate the parts so I was hopping that you could give me the dimension of the parts hat would be great
3d print them
you should get the rotor balanced for max efficiency
The rotor i'm sure it's balanced, the noise you hear comes from the bearings... I need to change them but i'm not sure whether i should go for full ceramics or hybrids...
What makes you think it's not balanced?
telefon72 there is no perfectly machined disk thats balanced. Just like turbochargers, if you dont balance the turbine wheels, they dont get top rpm to build boost efficiently also they cause major wear in the bearings just from a short run.
30GB But what makes you think he didn't balance it?
30GB Wrong. Jet turbines have machined turbines, they need to be extensively balanced.
very cool..i have a feeling about steam turbines hooked up with sonna tube HEers.. ceramics is the material
3:07 sound like turbojet engine :D
I would like to see this running from steam produced by a boiler on a camping stove.
How much power could one of these make
can it working with a liquid?
Can you please share a dimensioned drawing for those wanting to also build one?
where can i buy those end caps?
Nice job , also aTesla turbine is more efficiency with a steam fluid
is this scalable? say, an actual turbine/generator running on steam?
Bro, where's I to buy this turbine?, I need for college finall projects. Please tell me bro. thanks
Good Stuff Man...., Real nice video
really cool
How
much horse power does it produce?
A 3500 psl scuba tank would be a real test
perfect now it just need to be 10x bigger
Thanks
are you willing to share your blueprint? I need it for my school project :(
Very nice work . Have you found many applications for usage as i can think of numerous with great potential.
next step the air flow driven sports car :P

hi carlos Doug here. ive been wanting to do the same as you ive seen some good vids from jaromeASF and don schmidtke
hey a rc car mini wrench
i love that tool
ihave the same :0
Brandnew scrap
I honestly believe you skills should be utilized for more than just a hobby. You must get tired of hearing it. The idea is easier to manifest than it sounds. You uploaded 48 videos that proves you are inches away from success.
How much for one but a larger??
That wrench at the beginning was from a traxxas slash mantinence kit
no bearings ???
isnt it beter to use ball bearings?
Blades are the main parts and are designed aerodynamically.. Which ensure rotation by striking with air particles.
Bearings don't have blades
ah, a steam turbine from scrap materials we all got laying around........ >;)
I want to see someone power a Raspberry Pi with one of these. They operate on between 0.4W and 6.25W depending upon model and configuration.
You can use it as the RC engine
nice... very nice....
Now I want to see it run under about 800psi of dry steam.
donde consigo esos tornillos
How can I get one of these?
Would you ever make a sell them
Johnny getting technical? :D
Do you / could you sell these?
