Simply incredible work dude, I am a sophmore mechanical engineering major and I still cannot comprehend how you did this completely from scrap and determination. You are going places sir!
+Marie Miller it works alright but at higher rpm I have problems with valve float just like some car engines! Basically the spring isn't string enough to fully return the valve and follow the cam. Thank you haha
Just found your content today. I would love to see you come back to home steam engine engineering, I've learned a ton and confirmed a lot of my educated guesses.
In depth video on my steam engine with tips and how I built it! Enjoy! Sneak peak: I just made a boiler so videos and stuff of that coming soon! Stay tuned!
Nice work ! Your cam is interesting considering that older steam engines used an eccentric to move the valve. You could use your wooden base as a pattern to cast up a nice aluminium one.
Man, this is quite the resource! I've got an aspiration to make a steam-powered generator one day, even if it's just a USB charger, and this is the most explained one that doesn't require a lathe! Well done, my good sir, well done! Though I do have a couple ideas for it. Perhaps you could use some O rings to make your piston and valve leak less? Just spitballing, here. Implementing that might be harder than one would initially think. I know that this video is nine years old, but I'd love to see your take on a boiler! I've actually seen some DIY steam engines on youtube that used an old coke can for the boiler, though I'm not too sure how feasible that'd be, i believe soda cans have an internal plastic lining
Thanks for the video! Really nice how simple and adjustable this engine is, and that with really simple to get parts! Nice and clear explanation about how you built it!
I really need plans to follow to mirror you. I'm not a good designer but OK as a copy cat. Eventually I'd like to run some LED lights and charge my small devices when out camping. Anything that you might post would be a great help to the masses. Thank you for the inspiration to build one too.
Incredible build! I love this project. I came here looking for some information for building a steam engine, I left inspired. Keep up the awesome projects, I subscribed and I will be back for more.
really enjoyed your video. I like the simplicity of the design and the way you used materials you had on hand. It is very innovative and creative. Keep up the good work!
Your valve is not to small.Because on higher pressure it will pass much more volume etc,But valve leakage could be bad you need to add sealing glands. Very nice job indeed.Thanks for sharing it with us.
Shock Tones Hahaha thank you! But I think my brain works 10x as slow at sports, reading, and math lol. Everyone is smart and knows a lot about what they love. I love building things thus I know how to build a lot of things.
With this extremely low-tech engine, why didn't mankind have steam engines in the 17th Century? As an improvisationalist myself, I admire your efforts. You also sound like you're a youngish guy, so I'm even more impressed. It's simple... yes... but it works and that's what was intended, so mission accomplished! Keep it up, matey! All the best, Gordon
+Gordon Burns Search this on CZcams ,Heron of Alexandria 's Steam Engine. Was way before 17th , They just thought it was a toy and never made anything out of it
Lots of ingenuity, bravo! I'm wondering how the epoxy piston is surviving in real steam... any news, cos I'd like to try it? You might be interested in an idea I came up with for an adjustable crank while making a solar pump... join a threaded rod to the flywheel shaft, coming out radially, and with some clearance between wheel and rod. Vaseline the rod and mold epoxy putty around it. That gives you a long "nut" with virtually no play. Turn it to move nearer or further from the axle. Now join the crank stud to the middle of the "epoxy cylindrical nut" at right angles, giving a T shape, using more epoxy maybe. To adjust it later, just detach the coupling from piston to stub and give it a few turns. Your idea has the advantage of being adjustable without detaching anything. Mine has the advantage of, errr, laziness.
When balancing an engine, you need to add part of the weight of the big end of the con rod, because it moves along with the crank. As a first guess, assume that the effective weight is half the weight of the con rod.
Nice job! I just stumbled upon your video (you now have 1 more subscriber). I was laughing as you were explaining where u got the parts. I've got a shed full of compressor fans, bearings, rods, Fresnel lenses, microwave transformers and every kind of motor from 48v dc down to those little vibrating motors in PlayStation controllers. You never know what you'll need, it just makes it hard to throw anything away! As for positions, I bought a 4' rod of graphite a year or so ago. Its probably too big for your purposes (2" diameter with half inch bore) but I'd be happy to send a piece if u want. Ever try graphite spray? You could make the piston out of something with similar thermal expansion as the cylinder and spray the graphite on it. I've used it to build up graphite piston that I've sanded too much and I couldn't tell the difference. I'm working on a closed cycle steam system now and was looking for boiler ideas. Cheating a bit using rotary motors (from small vane motors from air tools up to an automotive scroll a/c compressor) and maybe use solar heat, hydrogen from aluminum in lye, wood, trash, etc to boil water (or propane or other refrigerant- Google Organic Rankine Cycle), expand in motor, condense in heat exchanger/ recuperator to transfer heat to preheat the water, and pump back to boiler. Follow that? Andy And again, great video!
Please explain the valve inlet and how the hole in the brass tube aligns with the copper tube going to the cylinder as this and the timing is the most critical part of setting it up. Thank you.
you do nice work my fiend!.........and you are very knowledgeable of steam engine building! ..... I have an idea you might want to think about .........you will need to make a steam engine twice the size as the one's you have made so far! .....but here is the Idea! .....make a "Steam Powered Bicycle"! ......I suggest you use a belt drive instead of a chain drive!....ENJOY!
if you widen the hole on your valve it will throw your timming off you will need to increase the dia. of the copper tubing and a larger valve to increase valume. but very nice job
I am confident that I can build anything like this however, I do not believe that I could have come up with the design on my own. You created this from mostly scrap, that is an amazing feat. You appear to have an abundance of potential. Please go to engineering school. Crowdfund your education or something, but definitely keep doing what you are doing.
Congratulations man! This mechanism is very interesting. I specially liked the way you designed the flywheel balancing method. You may redesign the cam's body to decrease the amount of resistant force made by the amount of gas in the cylinder while exhausting it, as well as increase the torque by forcing gas in the cylinder in a higher rate before the maximum torque point. Sorry if i made you confused with this. Do you study mechanics?
DAAAAAAAAMNNNNNN i was looking for a simple concept like this to make my first working engine sll by myself, i will try build one using your ideas, and i will promise when i build it i will make a video and send it to you and ofcourse with your name in it :)
is the exhaust the tube to the left of the intake copper rod when you apply pressure to the left intake "manifold"? Awesome build! im trying to make my own now
Clayton Reynolds With my design is doesn't mater which is the exhaust and intake. It only changes the direction. For example if I put pressure in the left one if will spin clockwise and pressure in the right one then it will spin counterclockwise. Thanks! Best wishes to ya man!
Nice machine! I am just wondering, why did you attach the valve shifting "arm" the way you did with a spring and rolling bearing on the flywheel? Is there any advantage to just mounting it regularily like you did with the piston arm?
I'm Really Impressed with how super simple yet ultra adjustable everything is. You can change valve timing or crank length in seconds :) Whle this video answered all my questions with your valve, I feel a more detailed video on the fabrication and spaciing to suit cam etc would be very popular for less experianced builders. No doubt you will make another (larger bore) one at some time, be sure to film it all :) I've been studying steam engines for some time, the valve is the hardest part. Yours is by far the simplest I have ever seen, and the only one I have seen that will run pressure and vacuum at the same time. Perhaps you could seal it with valve stem seals from an OHV 4 stroke motor. You may need to glue them on, and they would need good lube, but I think that would reduce leakage a lot. Or maybe grease your shaft and use some JB weld to make the air leak smaller? Looking forward to boiler tests. Has you mum padlocked the kettle yet? Is there a pressure cooker in the house? Because Mine has a nipple on it that would fit your hose nicely....
Mongrel Shark Thank you! That's how I wanted it! I try to make my Stirling engines in the same easily adjustable manner. It's nice when you don't have to rebuild the whole engine just to adjust something simple. Now I want to build a double acting steam engine because I want more POWER!!! I need a little bigger bore like you say, and I can't use epoxy putty as a piston. So I'm going to need to use some kind of metal or maybe graphite. The epoxy putty piston works great at room temperature but as soon as it heats up a little from steam it expands more than the copper cylinder and binds, causing the engine to run fine off steam for 10 seconds and then grind to a halt. I have a diagram drawn up for the valve so I will do a video on that one of these days. I just kinda eyeballed everything on this engine so there are not really and dimensions of the valve to give! But I still can do a video on the valve. A bigger valve would be nice too. Although then I would need bigger piping and an even bigger boiler. Hmm... There are much simpler steam engines than mine. Here is one: Homemade Steam Engine Pretty much any steam engine will run from a vacuum. Well unless it needs more pressure than atmospheric pressure. Basically all you're doing is using atmospheric pressure as your pressure supply. II guess stem seals would work but I would have to buy them. JB weld is a good idea to seal up the valve better but with my experience so far with epoxy and steam, it will bind when it heats up. With all the leakage on the valve, it still does seem to run just fine on steam. 30psi really makes it take off! Hahaha I was eyeing up the tea kettle when I first made it but I decided I might only be able to get 1-2psi from it because the lid does not seal well. Sadly we don't have a pressure cooker(if we did I probably would have turned it into a stirling engine by now). I already made a pretty nice boiler out of a tomato sauce can! It works great! I have a video of the hydrostatic test up so go check it out! You are going to be surprised by how much pressure a plain old tin can can hold! Hint: I deem 30psi the safe operating pressure! But it tested to way more than that! I really want to see the limit of a plain old tin can now!
I have cooked beans in the can on the fire. I can vouch for the pressure. The trick is to dint the can so if the dint pops out you know its close to exploding.... Saw a can explode once. Blew the fire out, and hot coals and beans all over camp. You might be surprised about how few steam engines would run on vacuum, especially vacuum and pressure at same time. Its not that common. I wonder if you could make piston rings for your epoxy piston? Thats kind of funny that it gets stuck.Must have had you scratching your head at first. I've seen pistons made from stacks of washers on a rod before... You can even put stuff like felt and velvet in between the washers, so it hangs out a bit, for a better seal.
Mongrel Shark Interesting! The denting idea is very smart! Just keep an eye on it! The beans were probably falling from the sky for a while!!! Hahaha Yeah, I guess I have't seen any running on vacuum before. I thought at first it was the oil in the piston mixing with steam cause it was puking out this gray thick gunk. But after I cleaned all the oil out and dried it all up it still did exactly the same thing. I don't know how I would make piston rings. But I'll give it some thought. I thought about something like that. I was thinking to cut the piston in half and sandwich some leather or felt in between the two halves. I don't know if the added resistance would be over come by the added power. Something to try though. I'm also trying to figure out how I would shape a graphite piston. I have a really nice piece of graphite that I've been waiting to use for that one special project! How do I cut it without making a HUGE MASSIVE mess?
If you wanted to mill a piston. if you can get a rod through the middle, that fits in your drill, you could spin it and work it like in a lathe. The gunk must be worn piston? Some steam pistons are as simple as string. The steam gets it wet and it acts as lubricant and a seal... Also look into steam oil. Apparently its something you put in the boiler, like 2 stroke oil in the fuel for a 2 stroke petrol engine.. It doesn't really rain whole beans. More like mashed re-fried beans.
Hey, I liked this video a lot, and I am wanting to make a steam engine my self any tips for me since you built one with no machining ( A hurtle I also have to over come) keep up the great work
The little Rod that lets the steam in you said you wanted to drill the hole bigger I don't think that's the problem I think you need to solder it to the other pushrod what's probably happening as it goes back and forth It's probably turning just a little bit I could be wrong but I'm assuming that's probably why they won't let as much steam in as it moves it turns side to side maybe you should solder it together and try that
very cool , have you tried running vac on one side and pressure on the other side, at the same time?more pressure and less vac and then more vac and less pressure? Yes you need to make better seals, look forward to seeing more vids!
scot fletcher No I never really did that. But it would certainly give a little more power. I have several other videos of it! Mostly running on my homemade boiler. Thank you!
man you're rockkkkk, that's awesome , i love it omg....this is my frist time doing steam engine so can you give me idea where i can buy all that stuff that you have? thank you so muchhhhh
Quite wonderful to see a young engineer at work. Congratulations, sir.

Your valve is not to small.Because on higher pressure it will pass much more
volume etc,But valve leakage could be bad you need to add sealing glands.
Very nice job indeed.Thanks for sharing it with us.
It sounds like an old sewing machine. :)
Great! Now attach a small generator or dynamo on it with gears and power up some led's :P
Awesome well done
Awesome work, It looks and works great.

Awesome, when you say it leaks, I think that is the exhaust, accidentally coming back through to where the valve is lol, great work, keep it up :-)
that is well done dude , Bravo
Dude this is just great! Really interesting :))
dude i like your style
Thanks for the follow up video
So cool!

VERY NICE!
Very cool my man its all the same principles in the big time set ups. Ha ha im impressed
Keep up the good work!
Nice work bro
You could do real wonders with a used old South Bend lathe or a little Sherline Mill.
That's awesome 👌
This is so cool!!!
Good job!

im working on somthing similar to this. that thing runs smooth as can be.
That's really cool
bnbcraft6666 Thank you!
great video
Kman Meteor Thank you!
hahaha you sound so young but your so intelligent, we need more of you
maybe put some sandpaper on the flywheel, and make it a grinder wheel!
+Adam Starhawk it is already a grinder wheel xD he just spraypainted it
nice job
Elegant!
With this extremely low-tech engine, why didn't mankind have steam engines in the 17th Century? As an improvisationalist myself, I admire your efforts. You also sound like you're a youngish guy, so I'm even more impressed.

The engine is the easy part. The boiler is the hard part. They probably struggled to build a big enough boiler.
You could use your wood base as a pattern for a cast aluminum engine base!
Good work! I like your valve & cam mechanism.

I'm watching this for the first time 8 years after it was made. I would imagine that by now you are one of Elon's chief engineers.
How does the exhaust/used steam get out?
Maker J 101 is the BomB!
The little Rod that lets the steam in you said you wanted to drill the hole bigger I don't think that's the problem I think you need to solder it to the other pushrod what's probably happening as it goes back and forth It's probably turning just a little bit I could be wrong but I'm assuming that's probably why they won't let as much steam in as it moves it turns side to side maybe you should solder it together and try that
what is the purpose of the tube at the back of the piston ,is there a hole in the intake canected to the piston ?
I really wanna know how he uses the second pipe to make it reverse. Is it the same inside as it would be with only one?
i feel like a meatball sub
In Depth Video on my DIY Homemade Steam Engine thats doesnt use steam to run but air - Parts Used, How I Built it, etc
Nice video,, well done,, but do away with that spring,, Cheers, Pete
very cool , have you tried running vac on one side and pressure on the other side, at the same time?more pressure and less vac and then more vac and less pressure? Yes you need to make better seals, look forward to seeing more vids!
scot fletcher No I never really did that. But it would certainly give a little more power. I have several other videos of it! Mostly running on my homemade boiler. Thank you!
why cast the flywheel if you made the counter weight? Wouldnt this work without it?
man you're rockkkkk, that's awesome , i love it omg....this is my frist time doing steam engine so can you give me idea where i can buy all that stuff that you have? thank you so muchhhhh
