What did you expect lol

[@V01d-57c]

💀💀💀

[@collinkaufman2316]

Get bigger cylinders or bigger stroke

[@GamingGenius777]

You should add another section to the valve so it pulls and pushes the piston. Basically turn it into a single stroke engine, which is how steam engines work in real life (there are probably some exceptions, though)

[@DeltonAdamsLEGO]

@@GamingGenius777 I actually planned on doing that, but the piston design wouldn't let me do it the way I wanted. I'll most likely make another that is a double action

[@pilotbug6100]

No most steam engines are two stroke, that's why it has the valve gear

[@GamingGenius777]

@@pilotbug6100 That doesn't make sense, and what does that have to do with the valve gear? Maybe you confused it with single and double acting. Most steam engines are double-acting (single stroke) en.wikipedia.org/wiki/Single-_and_double-acting_cylinders#Steam_engines

[@traugdor]

@@pilotbug6100 each movement of the piston is a stroke, so the steam engine has two power strokes per revolution making it a single stroke engine.

[@srenhaandbk7904]

I'd say make a double acting one instead. Here you're putting a lot of pressure on the valve, because it's closed for half the revolution of the flywheel, give or take, but a double acting one is only closed very shortly, and it's more efficient. Great work though, I'm impressed with what you achieved here.

[@Mm2ragetime]

I think I might build one my self!

[@BuddyTheWolfYT]

Put some lithium grease on the moving parts, there will be less friction resistance and should work better on lower pressure

[@BuddyTheWolfYT]

Or even a lighter oil that is plastic safe

[@DeltonAdamsLEGO]

Not for me, I'm trying to make things that are 100% LEGO. I don't want to have to use anything like sealants or lubricants. And besides, I'm not going for performance, I just like to build these 😊

nice work. Now make a working steam locomotive wheel model

[@Rose-yx6jq]

I'm pretty sure if you got it to run for long enough the friction that would cause so much heat to build up that you would fuse the bricks and plates together.

[@DeltonAdamsLEGO]

Well, yes, but you're talking about multiple thousands of rpms for long periods of time. This one probably only has a maximum of 1500, maybe. So that's not really a concern

[@zephranarx2172]

For holding stuff together, I'd say just use more technic pieces. I often see those get used just to really force creations to stay together, rather than fall apart because of basic brick-in-brick connections.

[@SimplyMyBuilds]

I feel like Pneumatic would be really cool for a design similar. Great job! 👊👍🎉

[@Kuzey4868]

Thank you

[@Hexearth]

I watched your hand in the beginning, when the nozzle was more centred in the gap it shot off the bricks, but when the compressor nozzle was pointing more towards the wheel then it worked. Might have been a parallax error but that’s my observation. As of now I’m yet to see the rest of the video lol

[@DeltonAdamsLEGO]

Yeah, when the nozzle was pointing directly in it increased the Amount of air that made it in and therefore increased the pressure

[@Mm2ragetime]

Wow!😮 so cool

[@s.sf.dsteamworks6961]

you should make a reverse direction engine ive made one with pneumatics in past instead of the 90 degree offset i did 0 degrees tubes done like normal i like your design here its well done and compact

[@thewafflegamer6152]

“Ferb I know what we’re gonna do today!”

[@sQuEeZyMaN13]

That’s not a “Working Lego steam engine,” it’s a working Lego PNEUMATIC engine.

[@DeltonAdamsLEGO]

In the LEGO engine space, the term is interchangeable, because real steam can't be physically used, but the engines can theoretically run off steam

[@BobMonkeypimp]

Steam engines can run off air. I occasionally run my real steam engines on air as the fuel can be quite smelly. Lubrication is key though - Obviously steam oil is required but when you run them on air, it's handy to introduce a little more.

[@rexcadral3468]

You should make a double-acting cylinder like a real steam engine. You won't have to jump start it. The trickiest thing to deal with is going to be the "gland" where the piston rod exits the block, as a cross-axle will leak terribly, you want a smooth sided axle for the job.

[@DeltonAdamsLEGO]

I'm actually working on one right now!

[@barrydheil]

That's the thing with steam engines like that, they were meant to be run with high torque, not quickly. Actually, one type of that steam mechanism was known to actually shake itself to death at high speeds.

[@operaatio5117]

I'd redo the valve differently. I think the main design problem of the valve is how the valve is built. If you built it "vertically" rather than horizontally, the valve wouldn't get pulled apart by the forces.

[@JB_Lego]

Amazing vid as always!

[@Threefinger-132]

Is that stopwatch for the air compressor or the engine

[@DeltonAdamsLEGO]

@@Threefinger-132 it's for how long the engine could run on a full tank of air

[@jamesgroccia644]

This is a good start. However, I think you'll find centering the rods easier if you keep the valve stem 1x1 instead of 1x2. Also, you can easily find the parts needed to make a round 2x2 piston cylinder. Circles have less friction than squares. I would also build a second cylinder on the other side of the flywheel (90° offset to maximize power). And another thing. I understand wanting to keep your channel funded, but charging money to get the pdf feels wrong to me.

[@DeltonAdamsLEGO]

I'm still working on different ways to improve this design. And also, its a dollar. Besides, I put a lot of work into making the instructions

[@DeltonAdamsLEGO]

@@Wreckedftfoxy well, what's really cool is that nearly every vacuum engine can also run off compressed air! So if you design an air engine, there's a good chance it'll also run off a vacuum! This one, for example, will run off a vacuum

Right. I was going to make this double acting, but the piston design wouldn't allow me to do that. I plan on making a double acting engine in the future. But for this engine, it's not really necessary

Huh. I was told it was Slide Valve System. I learned something new!

[@mossar1357]

You would have put an exhaust valve on the other side of the engine I think it would have worked better
