FYI, don't over tighten any of those fittings, rather, tighten them by hand, give them one quarter by wrench, operate the machine, and tighten them if they're letting out water or steam (depending on station). Those are notoriously easy to break, also, they're specifically designed to only go a little bit, until they seal. Just letting you know, i've broken my fair share of them. Also, 2 stroke oil is a bit loose, you should get something of heavier weight. Like way oil, for example. The steam will vaporize any of the oil it comes in contact with if it's too thin.

Johnny, you need to get some steam oil from the vendor for the in-line lubricators. The two-cycle oil is likely doing very little to lube the cylinder walls. Steam oil is designed to work in the high-pressure, high temperature environment of a steam cylinder. Remember, steam under 50 PSI of pressure is much hotter than 212º F. (100º C.). Those are beautifully made and running engines.
What does gasoline burn at? Or is the pressure more the issue at play here? We mix 50:1 for the chainsaws and blowers at work, just curious what the difference would be.
@@TheOriginalBlue62 The steam actually washes the oil off the walls of the cylinders when you use normal oil. Steam oil is made to emulsify with the steam, and remain on the cylinder walls to lubricate the rings. It’s a different environment than the cylinder of an IC engine.
This timing couldn’t possibly be more perfect. I’ve been looking up references for air engines to design my own in Blender, and I was trying to decide on the number of cylinders and their arrangement. Edit: I feel I should clarify that this is all for animation. I don’t plan on building an actual engine, but I want everything in the project to be as realistic as possible - something that could actually work if it were real.
If I recall the triple expansion steam engines are by far the most efficient and powerful steam engines known to man because of how well they use superheated steam
2 stroke oil is alright for the external parts but the cylinders really need steam oil as it's a lot more viscous and can handle the pressure and heat will help the cylinders last a lot longer wouldn't want you to ruin them as I bet they where not cheap
I’d also agree with the recommendations to use steam oil in the lubricators. I’d also recommend watching Keith Appleton’s UA-cam vids on building, refurbishing and operating model steam plants. What he doesn’t know about steam engines is probably not worth knowing.
If the safety valve is rated 60 PSI, I'd run it right up to that for the extra oomph out. Looks like the little engines that could need it. They do seem to do well under load as well, as you've noticed. They don't seem to bog down near as much as the gas engines, possibly because they can always be fed power via the steam in, which can rise in pressure when bogged. Neat little engines.
Very cool Too bad they are both single expansion and since the pistons all appear to be the same diameter you probably can’t convert to double or triple expansion. Any chance you can make a condenser so you draw a vacuum across the exhausts? You may see an increase in power out put.
back in the 70s my grandfather and i got an old 50s steam train from the thrift store. needed alil work but we got it going. it was fun to watch it steam run on the tracks. nice vid, ty
These engines are absolutely beautiful. Craftsmanship looks fantastic. I was a little surprised that they can't run slower than that. Especially since they're multi cylinder engines. Maybe they're not double acting cylinders if not that the reason. But if they are double acting they should be able to run much slower than that. Could be a steam regulation issue or perhaps the timing is slightly off. Could just be that they're very small cylinders also. I had a little single cylinder steam engine for a long time. Just used the sweeping style back and forth valve. And it would run quite slowly.
I'm really impressed and amazed at how well and smoothly the machines run, and especially the three-cylinder one. Right now I wanted to buy a steam engine again (the three-cylinder of course). almost 50 years since I last bought one. Then of tin type on tin plate, and with 1 cylinder, but I had a lot of fun with it, saw and steam hammer came with the set. The other boys were very impressed. Thank you for allowing us to take part in a great demonstration and a great video.
That 3 cylinder steam engine sounds beautiful. It’s now on my wishlist for Christmas lol. I probably would use it as a power plant for electricity or something.
I hold 2 jobs, machinist, and manufacturing engineer. We share a lot of the same skills, and I haven't seen u do anything contrary to industry standard. You sir are a skilled man,. I wish I could use my skills to have fun lol.
8:06 the brushless motor is producing around 1.5 watts of power, so the steam engine should be producing even more. Maybe there is a problem with the dyno test? (9:14) best wishes
I love steam power! Especially the reciprocating types like these. It would be amazing to see you build one from scratch. A triple-expansion, or the rarer 4-cylinder triple-expansion would be really interesting to see. I've always wanted to build a 4-cylinder triple like the ones used on Titanic, but i simply don't have the equipment or skills required to do so. Yet. Thanks for the video!
I was under the impression the Titanic only used 3 cylinder triple-expansion engines. In fact, I've never heard of four cylinder triple-expansion engines before, would they not be called quadruple-expansion engines?
@@Kyle-gw6qp they wouldn't be called quadruple expansion because the third expansion is just split between 2 equally sized cylinders. They did this to reduce the weight/size of the third expansion components and to minimize vibration. A true quadruple expansion engine would have 4 different sized cylinders. 1 for each stage. If you want to see a really well done scale model of Titanic's engines, look up overweightarchie on youtube. He's got thousands of hours into it and it's arguably the best functioning model of the engine in existence.
i like those demonstrations with the light bulb, turning LOTS OF FIRE into a tiny bit of glowiness :P shows you how inefficient energy conversion actually is.
Lovely looking little engines , sound nice too. So are you going to make a condenser for exhaust gas and feed it back into the boiler via a one way valve?
I can see the exhaust condenser working - lots of stationary engines have them, but you couldn’t directly feed it back in as the water would have to be at a higher pressure than the boiler to be able to get through the one way valve. He could probably machine up an eccentric pump though, they’re common on locomotives.
@sourand jaded they can be really finicky on miniature steam engines, they’re fussy on pressure and also don’t like hot feed water - which is a problem if you’re getting your feed water from a condenser, they tend to condense the water properly but keep it a bit warm. It’s definitely possible though. Some boilers need certification in the UK and US and to get one certified you need at least two methods of water input, so there’s no reason why you couldn’t have an injector and then a hand pump for if it fails.
I have a two cylinder steam engine that has only been tested with air power cause I’m still building the rest of the boiler components but I absolutely love watching all the mechanics at work at extremely low RPMs. Great vid as always 👍👍
Now you need to build a scale RC steam launch. And have a little figurine crew with at least one wearing a Panama hat and drinking tea out on the deck.
I'm not surprised you didn't want to push your luck regarding the pressure on the boiler. What you could do though, is a water pressure test on it yourself, it's a lot safer to test it that way and is quite simple to do.
Every time i see a steam engine it reminds me of the Netherland open air museum in Arnhem where they have a old milk processing plant with a working steam engine which they actively run... amazing machine 🥰 amazing place too ❤️
So fascinated with steam engines. Insane amounts of torque, but this demonstration makes me think they could never be practical for road applications again.
the triple expansion boilers with superheating tubes really did have tremendous torque, but your talking thousands or tens of thousands of times larger than this little thing.
@@Steve211Ucdhihifvshi You caught me about two years too late to discuss this with any competence. That said, I'm pretty sure I was referring to steam cars, like the White steam car, which makes an estimated 800 ft/lb torque.
Silly little project for you to try. Historically most steam ships would squeeze a little more power out of their steam engines, not by heating the steam more (and risking damage/boiler explosion), but instead by cooling the exhaust through a heat exchange, with some fresh seawater. Perhaps pipe the exhaust tubing through a water bath before releasing it, and check the power again.
Hi Johnny, You have inspired me to order this setup for myself. I ordered it today and it should arrive in a couple of weeks. I have a few question about what we see in the video compared to what's actually included in the kits: 1. What's the smaller vertical black cylinder for, and why wasn't it used in the build? 2. Were the holding braces for the Gas Tank included? 3. Was the brass fitting you soldered to the pipe included? 4. Is there anything else I will/might need for my setup to be functional?
Hi, I am also interested in getting this kit, but like you would like to know about what is exactly included in the kit. Could you please let me know? Cheers. Serge
I'm sure somebody may have already said it, but: RC Titanic. Two engines powering the port and starboard 3-blade props and somehow run a generator or scale steam turbine to power the center 4-blade prop.
I would love to see the cylinders working in series. Although they probably are designed for that so it might not work well but I think that’d be cool to see.
You'll notice they have functioning valve gear, this means you don't need multiple expansion in order to improve efficiency. You just move the johnson bar closer to the center and it'll close valves early, allowing the steam to generate mechanical work by expansion. In scenario of full expansion from working pressure to atmospheric, you get maximum possible efficiency. It's basically the same as having fixed timing valves with multiple expansion cylinders that expand to atmospheric pressure, except you have an option to "overdrive" it and produce more power at the tradeoff of exhausting underexpanded steam.
Great video as always but i noticed something. You were able to produce 1.5 w of electrical power using a generator but you were only able to produce 1 w of mechanical power with the same engine. This doesn't seem right, maybe the dyno gives us fals results.
@@VintageTechFan a dyno is designed to test HIGH SPEED torque ... a steam engine is considered low speed torque ... so the steam engine will start fast and finish at the same speed ... while a proper engine will start slow and finish fast .... a steam engine isnt abut going fast it is about moving heavy loads and doing lots of low end muscle work ... while an engine is about constantly accelerating adding more and more speed to the power curve ... put a car engine on a jet engine dyno and the car engine looks like a peddle car ... same idea as a steam engine on a race dyno ..
you could BUT then you woulld have to use a governor to keep the engines in sync with each other ... parallel and you can run two different sets of things like say a generator for lights and some battery charging ... and then bands for tools and machines like lathes or drills or sanders or saws etc ... literally a miniature machine shop run from 2 steam engines with lights and all fully functional ... ok so they are best suited for smaller parts and more likely softer metals ... but perhaps can be used to actually make the models with scale sized actual machines ...
But what was the cut-off set to. Did you test on the dynometer with maximum steam expansion (maximum economy) or maximum intake (max torque and highest steam rate)?
Is there a way to add water to the boiler while under pressure? Not necessary with butane, but handy if you want a longer run. Nice running, very well timed engines!
Fantastic video, but I have to say, I think 2 stroke oil is not the best for these engines. I'd advise getting some proper steam oil, or use a thick engine oil instead. I'm sure they'll run and sound much smoother with the correct oil
As beautiful as they are you're taking a step backwards with thermal efficiency. That said how awesome would it be seeing one of those in one of your cars... it could be Steam Punk themed
I wonder if its possible to make a small steam turbine to go alongside the main steam engine, connected to a gearing system, to act as turning gear system. So in theory you could have a high pressure burst of steam, maybe lasting 5-10 seconds or so, that would spin up the turbine, turn over the pistons to remove any water, before then being able to start the main engine. If calibrated right, a governor could open the throttle valve to an idle (or maybe a "start up") setting right as the waters cleared from the cylinders, whilst also closing the valve to the starting turbine, making the start up an automatic proceedure automatic. Don't know if this would work in practice but if I had the time and tools I'd love to try and make it work. Not only is it a cool little party piece, it would also sound incredible. The hiss of steam, with the winding up whirl and shriek of the turbine, followed by the main engine sputtering and roaring into life! Edit: Doing that maths thats about 1.63 hp/L, and about 13.07 Nm/L which isn't half bad for what it is I think!
Interesting. The Liberty Ships circa WW2 used triple expansion piston steam engines because steam turbines were in short supply and were mainly used for war ships. Later in the war when steam turbines became more available they were used for the bigger/faster Victory Ships.
is it safe to add more gas while the boiler is burning or does it need to shut down before you can refuel? same with topping up the boiler with extra water?
Next level: Titanic style, with a low pressure turbine in the center driven by steam driven by steam after leaving twohigh pressure engines like yours.
The sound of these engines is enchanting! Very beautiful tests you did!

I wonder if its possible to make a small steam turbine to go alongside the main steam engine, connected to a gearing system, to act as turning gear system. So in theory you could have a high pressure burst of steam, maybe lasting 5-10 seconds or so, that would spin up the turbine, turn over the pistons to remove any water, before then being able to start the main engine. If calibrated right, a governor could open the throttle valve to an idle (or maybe a "start up") setting right as the waters cleared from the cylinders, whilst also closing the valve to the starting turbine, making the start up an automatic proceedure automatic. Don't know if this would work in practice but if I had the time and tools I'd love to try and make it work. Not only is it a cool little party piece, it would also sound incredible. The hiss of steam, with the winding up whirl and shriek of the turbine, followed by the main engine sputtering and roaring into life!
Edit: Doing that maths thats about 1.63 hp/L, and about 13.07 Nm/L which isn't half bad for what it is I think!
7:16 what software u are using on your phone?
Interesting. The Liberty Ships circa WW2 used triple expansion piston steam engines because steam turbines were in short supply and were mainly used for war ships. Later in the war when steam turbines became more available they were used for the bigger/faster Victory Ships.
is it safe to add more gas while the boiler is burning or does it need to shut down before you can refuel? same with topping up the boiler with extra water?
Super cool project, might get me one for Christmas.. 👍
I love steam engines, if they can't take the load, they just ramp up the pressure and power through them
I need that 3 cylinder, sounds so good. A little bit like a lawmmovor too, but.
My man JohnnyQ 3D printing a funnel xD
Would it be possible to condense the exhaust steam back into water then back into the boiler tank?
I’d love to see you stretch what’s possible with steam power!
Very good video👌
Next level: Titanic style, with a low pressure turbine in the center driven by steam driven by steam after leaving twohigh pressure engines like yours.
Is there a way to make one that’s larger or has more boilers with more controls? With a boat would be cool to
Could you feed the exhaust back into the boiler?
don't use 2 stroke oil. for the bearings use light machine oil, and for the cylinders use steam oil
