p.s I haven't forgot about the micro supercharger, I need first to review one more engine that has been sitting in my desk for months and then back on the sc!
"That could run your heart for 50 lifetimes"
"Or something big for 15 minutes"
Ye saying i got a midget heart?
Something big...like a Gotland-class submarine perhaps?
I'm gonna watch iron man right now. Thank you for unknowingly suggesting it friend :)
How did you find that out 😳
half the people wont even get it lol
you should machine the inside of the "flywheel" to balance the eccentric shaft on the other side without undermining the aesthetics, might help reduce vibrations.
I imagine the order in which the set-screws are tightened may also make it a little eccentric, perhaps this is how it might have been balanced originally.
No, it clearly needs a second one mounted to its back 180 phase shifted for balancing.
Brilliant! Please put the word RADIAL in the title! Those of us who especially love all radial engines need to see this! You have raised engineering to an art!
Just looks like a Radial Engine. The reason I say that is because only 2 cylinders are producing power, the other 6 are just along for the ride, and bleeding power from the engine. Would you get into a plane that only had 2 plugs in it? Would have been better to build it horizontally, then heat all 8 cylinders.
@@warrenjameson5465 4 are hot Displacers & 4 are cold Pistons.
Left 2 & Right 2 = Hot
Top 2 & Bottom 2 = "Cold"
Thank you for fixing that flywheel. That was the first thing I noticed.
what was the significance of that?
@@abdullahjeffers9098it will off set the racers slightly over time causing it to fail altogether. Anything that spins for a long duration, needs to have all components run true.
What is "run true" ?
@@darkexcel straight, without slop
The poor thing clearly wants to be set up with a vertical rotational axis.
I too thought that could help, it might be more efficient.
would also allow him to heat all 8 cylinders, and maybe add a counter balance to the back end to smooth out the vibration instead of taking material out of the flywheel as suggested above. (both would work)
@@slickit86actually the way it works is that some of the cylinders are heated and some are supposed to be cold so the heated air cools down after being heated
@@HighVoltageMadness wouldn't that only work if the cylinders are actually connected?
Nathan Lang they are
I have discovered a channel by the name of " mona cai" frequently reuploads your videos with different logos.
@@hfyudtkdkhk only the legitimate content creator can issue a claim for stolen video, it will just get ignored otherwise.
i discovered such a problem once too, about exclusive release information of monster hunter world content that will be coming out, was only 1 video and not even more stupid like frequently, problem was the owner of the channel was in vacation and didnt see it but a lot users went over to report it and we were able to make youtoube react you only need enough people for it.
Michael S eh i wish that was the case. Copyright abuse is rampant on this platform for the very reason that companies can claim they own something and make money off of it even if it’s not true.
Do they leave in the watermark?
i have the same problem, one chap down loads my diving videos and posts them as his own
Cool design!
Small stirlings suffer practically every time from bad heating.
Your design is partly obviously classical and also very innovative, good job!
I am an American living in Brisbane Qld Australia. I just want to say that at age 67 I say Congratulations on this Engine. We built similar Engines when I was in my Twenties.
SCOTT STIRLING!! The man, The myth, The Legend!
Thanks for the pure aesthetic pleasure. RUclips has so much of the fleshly kind.
Thank God this is only ten minutes
I have other things that I am supposed to be doing
LoL!!!
Really only a 4-cylinder, but I'll allow it. ;)
Shawn Elliott well it has 8 cylinders but it just only uses 4
@@thetriforceeagle8161 It's "using" all of the cylinders, four of the cylinders are power cylinders, the other four are displacers.
I think in this case the engine is an alpha type Stirling engine and the 4 pistons not being heated are the heat sinks or "cool" cylinders and not displacers
@@hjc1935 Yes, you're right, I stand corrected. However, in a rotary design like this, all the pistons work together to move the working fluid between hot and cold side so effectively function as both power and displacer pistons. A very nice design, I still don't understand why the orientation isn't horizontal.
Steve Ramsey aesthetics probably.
Thank you RUclips for putting this in my recommended. This is awesome!
Rugrats Pops: Back in my days, we had pencil sharpeners that were gas powered. I had to walk 15 miles to get to the gas station!
Great work :) One quick tip - no matter how accurately components are machined, they still need balancing for optimal work (the issue now is with shaft - not flywheel).
Had some pretty bad memories on the topic of Stirling engines, and then this video title get reccomended to me.
I will tell a story just to get the frustration off my chest.
This was when i was in high school, and we had to do a science research project. This was the kind where you had to show the proper usage of the scientific method.
We were a group of 5 people, nobody wanted to be the leader, even me, but i stepped up because i wanted to graduate highschool.
Now if anyone asks, im not really fit to be a leader since a good leader for me has the following traits
-Likeable personality
-Communicates very articulately
-has a lot of friends
I was the quiet kid with very few friends, so im pretty sure my other group members didnt like that i was the leader.
My problem with the topic of stirling engines came when we needed to come up with a research topic.
For starters its quite hard to give an acceptable research topic. it had to be simple enough that a highschooler is smart enough to record the data. It needs to be cheap enough that we dont ask our parents ridiculous amounts of capital, and it has to be a topic that has not been done before.
Quotations on "has not been done before". The school has like 50 years of highschoolers doing this project, and if the teacher rejects the topic because they know a previous group has already done it, then we need to come up with a new topic.
i couldnt come up with any acceptable ideas, about 2 of mine were shot down. Now i asked my group members to help me think of ideas for a title topic.
i asked them to suggest at least 1.
and then we have this certain guy. He's usually a decent dude, but he was pretty bad for the health of the project in this case. His idea was "lets make a Stirling engine" we went and asked what a stirling engine is. It looked like some spinny metal contraption that runs on some kind of heat.
Now since im the quiet kid who just thinks alot, i intuitively know that the idea isnt going to work out as a topic, but i was not able to properly communicate to him "why" I probably was not even smart enough to articulate what i wanted to say. But now that im typing here in the comments, its pretty easy to explain why it was a bad idea.
It was because it didnt ask a question. and it also had no controlled and independent variables.
Simply building something cool like a stirling engine does not make a research project. You need to build something cool and compare it to something reasonably similar and mundane.
He kept insisting that he had a good idea, and i kept saying its not going to work, and after that he goes and says "well i suggested the minimum of 1 idea, now you guys come up with a better one"
It basically felt like malicious compliance, pushing the responsiblity on everyone else while also doing my condition of 1 suggested topic per member.
That whole ordeal made me feel quite retarded to be honest.
I felt like people would hate how i looked unempathetic to that member
I felt like i was not smart enough to explain the problem
I felt like i had to do everything because nobody wants to help.
We later settled on a rather a dumb sounding topic i came up with. Deodorant using different citrus fruits and comparing it to commercial deodorant.
If anyone is interested in the results, it was pretty bad, the orange, lemon, and calamansi juice ended up smelling like rotten fruit on the armpits overtime.
I imagine that "heat soak" plays and important part in the operation but it sure looks like you could use even small sized wicks.
Another beautiful and interesting build. Looking forward to more of your videos. Love your "cut to the chase" editing!
@Peter Haan
He didn't build this one, he bought it. Link in the description under the title.
I like the style of this motor! Between steampunk and wastelands with a touch of futuristic
Yes, it would have been easier to true-up the original flywheel.
but way less cool
When I grow up (i.e. retire) I want to be just like you! These projects as well as the quality is amazing! Keep it up!
Man this channel has literally everything I crave to watch lmao
Michael Macrae --- yea me to and l worked 30 years in this feeled and l still can't keep away. Now days not many people can fix any thing from the past and if things go bad some of us can re-start many machines make parts and operat them to get machine's fixed with out any power ( ELC) exp for water power, hit and miss moter's .steam power etc. etc. I can even re-cast steel and such. Most men why l live are very quietly getting all of are machine's up and running. Have made many older tractor's are running and their plows , ballers. Milling machine'd things like this year l love this stuff. ( But just in case.)
DAT CONE!

Here’s a meta idea, convert it into a small balsa wood lathe! Love your work, I wait for the huge version ;)
This was a nice video. No obnoxious house or dubstep music, clean editing. Loved it
The turning and machining of the fly wheel interested me because that is what I'm doing for my job, just instead of the the flywheel im making medical screw implants, but still it interested me because I'm just starting out and am learning more and more about being a machinist, that was my favorite part of your video.
great video, as always. But it seems to me that the engine is 4-cylinder. 4 cold and 4 hot, each single cylinder stirling engine carries 1 cold and 1 hot to complete the heat transfer. Greetings
This is a real workmanship! Much respect! Very nice video,too! Biiiig thumbs up from Switzerland!
Martin post on your channel like the pro 4 i miss that stuff
@@gsf2817 Cool you like it! Be patient, a new Pro4 is under construction and I will do the first runs in July/August ;-)
Just what i wanted to hear
@@gsf2817 :-)
I just got one. I tried both rubbing alcohol and methyl hydrate, and I had much better luck keeping all 4 wicks burning with methyl hydrate. It does produce a cooler flame so warm up time is a bit longer and the engine runs slower.
Isn't that like, the least weight efficient shape for a flywheel
Yes but looks cool
@@j.t.bumbaday1489 hell yea it does look cool 😎
I noticed you manually feed coolant a lot. My favourite trick for this is to hold a candle to the spinning workpiece - leaves a nice cutting film of lubricant on the part, its easy to apply, very clean and smells great, never spills, doesn't spoil, and it's super cheap. Have you ever tried it?
If you think about the thermodynamics: the amount of energy produced from which one of cylinders is a product of temperature difference between hot and cold spot within each motor ( I conclude myself in easy way) . So as many suggested also before me: the best result will obtains when you turn the wheel into horizontal plan and/or make sure than each cylinder gets some amount of heating ( preferably equal amount) and at the same time make sure that you have the cold spot for each and every motor. Then theoretically you will get the highest efficiency thus highest outcome RPM.
When drilling and tapping for the spinner's grub screws, drill them at 90 degrees to each other. You'll find that your method allows some wobble and in time they will work loose. But at 90 degrees that's eliminated.
the original flywheel was off balance to balance out the inner workings. it is now lugging because of extra rotational stresses
You should make a mechanism that will heat up all the cylinders together because now it's basically 2 pistons turning the whole thing
It has 4 hot pistons an 4 cold
Nice work. I manual machined the Potty 3 Cylinder Radial many years ago, very similar but uses an orbital valve to run on compressed gases like air, or steam if I had made it out of stainless and brass instead of aluminum and mild steel.
So THAT'S what the Clockwork Soldiers have on their shoulder in Dishonored 2. A Stirling engine. Huh...
Ingenious little design there. I wonder if it could be heated off the rising column of hot air from a stove or perhaps sunlight concentrated through a Fresnel Lens?
move the heating element back, use it or a boiler medium to melt a closed pipe assembly filled with parafin wax, then wrap the piped parafin around the hot-side pistons, insulate the section of pipe between the heater and the coils. the wax has a high transition range between solid and liquid, so once heated the energy can be stacked pretty high which might more efficiently use the energy produced by the burning wick. That is, assuming the heat given off by the coils of molten parafin around the pistons have enough energy output to run the engine
Why didnt you run the indicator after you polished it by hand?
Manual manipulation will wear the outside unevenly. Was turned true, but I get it.
@elijah mikle It is not pushing material into the low spots as the primary operation, though some deformation along those lines would occur. That was an abrasive 3M foam sanding block. Aluminum is not that soft and the polishing operation doesn't get the metal hot enough to deform. Your sound wave analogy is good though from a surface cross section perspective. Like a glacier, the abrasives knock down the high spots. FYI: Rouge is technically an abrasive .. just a very VERY fine grit one.
So relaxing watching shaving the aluminum
Congratulations from Brazil!!
What Is Islam?
Islam is not just another religion.
It is the same message preached by Moses, Jesus and Abraham.
Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God.
It reminds us that since God created us, no one should be worshipped except God alone.
It also teaches that God is nothing like a human being or like anything that we can imagine.
The concept of God is summarized in the Quran as:
{ “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4)
Becoming a Muslim is not turning your back to Jesus.
Rather it’s going back to the original teachings of Jesus and obeying him
@@ahmdabdallah5811 What the fuck?
I'm so glad you fixed the stock wheel it bothered me so bad
Bravo c'est toujours du très bon travail propre et efficace même si perfectionnable, c'est excellent de voir autant de projets et plutôt bien filmé
Perfectible :-)
Et c'est valable pour tout le monde ! :-)
I’m looking to buy a lathe in the near future, and yours looks perfect for what I’ll be needing to do! What model/brand is it? Love your videos btw!

For everything else, there's mastercard
Good one haha
Hope you had a great poo
Outstanding Sterling Engine, love the Nixie tube design.
If heat distribution is questionable a Peltier device may be implemented to lower specific locations.
Finally, an 8 cylinder engine that will fit my Peel P50
You build beautiful machines. Keep up the awesome work man.
Excellent craftsmanship.
Wow, you've got a lot of technology. An addictive video. I can't stop it.👍
Beautiful work, beautiful video. On a personal note, when you fixed the flywheel I felt genuine relief.
Very nice! I think the next step would be to use an electric heat source for each glass. Ceramic heating element.
Considering sterling engines work off of heat differentials, i don't know that running cooler is nessesarily a good thing...
It is if you are in a submarine
Where do I sign up and learn how to do this? I started building model airplanes and rockets when I was about 12. Started mechanics around 13 from lawn mowers to dirt bikes to building my first car at 16. (78 camaro) Worked on all my friends cars in high school too. I am absolutely fascinated.......
I've always found that when I would burn a fuel, via a wick, the higher the reservoir was placed (less uphill work for the wick) the more efficiently the wick would provide fuel.
You have marvelous designs. Do you have any of your designs doing work?
If Iron man's arc reactor took a steampunk theme, this will be it.
If any one make a steampunk Tony Stark comic this needs to be in it.
Weakest Ironman suit ever made lol. Maybe power the light in his helmet
StirlingMan
Put the engine in horizontal position on top of fuel reservoir, that way you can have equal length wick for every cylinder.
I would love to see you produce your own stirling engine. Somthing where you can turn fly wheels and cylinders on your lathe with precision. That wpuld be an incredible A to Z project and I know you could do it!
A new episode of John fixes cool stuff? Must watch
The difference in weight of the new flywheel is why it has slower RPM
Holy Shit! That's what I was working on too. Good work on your model.
You NEED to make it work with all 8 cylinders
How much "Work" will the engine actually do?
Probably not that much but that's not really the point of these engines anyway.
Don't know about this little model one, but here in Sweden we use Stirling engines on some our submarines. They operate _very_ quietly, and rather efficiently since cooling isn't a problem under water. I think they use helium as a working gas, it's more efficient. So Stirlings can definitely do some work.
@@Shabbymannen Worth noting those Stirling engines are quite large if i remember correctly, as tall as a man at least.
@@stompyrobutts : Yea they are big alright. I havn't seen one in person, but I don't think they are much larger than the engine on a conventional diesel sub.
T-Gay there are some micro power and heat plants that can be used to heat houses and generate electricity. Only makes sense if you substitute electricity from the net which has been produced with higher emissions (also if solar + heatpump is not an option) Stirling engines combust fuel very efficient, much more so than combustion engines or coal power p.lants
Man I would kill for a lathe and milling machine
Nice engine good fix and smooth operation, fun project likely.
Lance & Patrick.
My friend has this in his honda civic
I might be wrong, but shouldn’t radial engines have an odd number of cylinders? Look at old aircraft radial engines. They all have 5, 7, 9, or 11 cylinders.
The number will always be even with stirling engines i think. Since each stirling"engine" requires a hot and cold cylinder
This guy should get pattern under his name for making any machine model
With Father's day coming up I want to get my father one of these type engines, with him being 61 and a mechanical engineer for 37 years....what style of these engines would you recommend?
Very, very, very cool. First time I've seen a Stirling engine. What are you using for lubricant? I like your use of it wether it's water or mineral oil. Either way, you're doing everything right!!! 👌 1200 rpms on that thing too, wow. Just wow. Impressive.
You could have made an exhaust guide so that the fuel burned at the bottom the heat flows over each tube for more efficiency. Make it out of glass too, for added beauty and complexity. Don't connect it to the cylinders, just make a hole for the cylinders to poke into. It wouldn't have to fit the cylinders exactly, as it's more a guide than a sealed containment jacket.
Yo, your plane is missing a prop
Looks super efficient
This is the only radial engine I've ever seen with an even number of cylinders.
just a weird thought that could have been applied here to fix the wicking issue.i have a few and also made a few certain kind of camp stoves,where like this thing,had tubes with wicks,but a flame heated the tubes,turning the alcohol into a gas under pressure,then came out of ports and was lit.hotter flame,and more consistent.
Most elaborate bong i've seen in my life
😂😤😗💨🌫️🌫️
slightly less rpms for half the fuel burn? wow
EDIT: correction, it probably has much less torque now than it did before. Still nice for a propellor
I think it would have similar, but a bit less, torque. The original design was just rather inefficient, since the heat from the bottom flame could still reach the top cylinder, but the heat from the top flame got mostly wasted, as well as being choked for fuel.
Aa much as people want to call it four cylinders it really is not because the air tubing all seems to go directly from lit cylinders to non lit cylinders basically making them afterburn, even a type of egr system.
At the beginning of the video, you have scenes that come out of focus, did you do this with the camcorder? Does your camcorder have manual focus?
What is the model and brand of your camcorder?
Leandro Wagner.
Hi Leandro. Yes it has manual focus and this is what I use for these shots. It's a canon 100d with EF-S 18-55mm IS STM lens. A very basic setup.
@@johnnyq90 Thanks for the answer, it's the same camera you presented in a 2017 video, I need to buy a camera, but since my country is experiencing one of the worst financial crises in history, I still have to wait. I really liked your camera, when possible, I intend to buy one like yours.
Leandro Wagner.
It sounded smoother with the new flywheel .
Satisfaction is strong in this one
What a great piece of atomic bonds.
more energy to build than it will never make xD
Maybe you can shield the hot cylinders and mount a prop to cool down the oter cylinders. And maybe it channels the heat of the burner better. And my last idea. Maybe the gasburner of the 16 cylinder striling engine work better.
Looks like gravity is causing that vibration. If it was pointing upward it would probably help the vibration.
Can’t wait to put one of these bad boys under the hood 😤
You should have used 3 setscrews to be able to fix the runout. With just 2 screws, there's always a degree of freedom in which the part can tilt.
Amazing work! Kinda wish u used all 8 cylinders tho
All eight are being utilized. In a basic stirling engine, you have one cylinder which absorbs heat and one that radiates it. The act of moving the energy from one cylinder to another is where the work is generated.
This is so useful
Never seen such a thing
I love doing prototypes. Not the workings , but all the pieces. Making it all fit together.
Does it fly?
I spent more time being fascinated about the cutting of that aluminum!! and the little guage that he used... there's a tool for nearly everything!
This is interesting although it has use in the automotive world the look and sounds are satisfying to hear and see
I don’t know what it is for but I really enjoyed the video!
Great Job! I like people that never stop thinking!!
this is the cooleest sterling engine ever
Thanks Kanye, very cool!
Even the 'fixed' flywheel was not running on center when it was done, it too still wobbled, albeit to a far lesser extent, the problem with single ended crank shafts is that they have a horrible wobble about them.
Great for when the lights go out and u don’t have any fan
Sick you craft some awesome things must be an engineer!
