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.

[@TheOriginalBlue62]

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.

[@tjh44961]

@@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.

[@niels6101]

One or two notes, first: use steam oil instead of 2 stroke oil. Especially for the cilinders. It's much better for the engine. And the second note is, consider a feedpump for the boiler. It will save you time and you can steam much longer! 😉

[@IncertusetNescio]

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.

I’d also agree with the recommendations to use steam oil in the lubricators. I’d also recommend watching Keith Appleton’s KZbin vids on building, refurbishing and operating model steam plants. What he doesn’t know about steam engines is probably not worth knowing.

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!

[@Kyle-gw6qp]

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?

[@Matt_Deluca]

@@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.

[@kens97sto171]

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.

Wow hit a nostalgia from a time when this channel only posted video of Motor Stirling! Flees times...

[@__-fm5qv]

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!

[@chrisvinicombe9947]

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?

[@harryrobinson2901]

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.

[@chrisvinicombe9947]

@@harryrobinson2901 I didn't think of that. Makes sense

[@harryrobinson2901]

@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.

[@HeatAndPower]

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.

[@michaelbuckers]

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.

[@jctrains9286]

If your bring your cutoff back you can get faster using less steam and expansion, the closer you bring it into the middle, for example half forward: 50% of the piston stroke is steam and the other half is the steam expanding, this will also increase your speed

[@BaffledApe]

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.
