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.

The sound of these engines is enchanting! Very beautiful tests you did!

[that__ranger]

Wow. Would definitely love a steam powered rc boat

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.

The quality is amazing. They sound awesome too

[artificer]

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.

I love the sound of a three cylinder engine!

[KaushikBala]

The 3 cylinder uses the heat more efficiently and nearly 50% more power. Just amazing. Loved this video

[niels]

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! 😉

[MrFishingbros]

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

[davidgriffiths]

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

I'm surprised how real that 3-cylinder sounds

[paulterhaar]

That 3 cylinder sounds a bit like a 6 inline petrol engine, I love it!!!

[darylmorning]

I don't think I've ever liked a video in the first 20 seconds before. The sound was AMAZING!

[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.

[benanddadmechanical]

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.

I literally just parked at the side of the road just to watch this video now. So excited ❤️

[coreypratt-e]

Definitely one of my biggest inspirations on YouTube 🤘

[Matt_Deluca]

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!

[blackericdenice]

So this is how they powered the Titanic.
10:09 It funny how a 3 cylinder sound like a 6 cylinder.
