Posted July 29, 20186 yr https://youtu.be/UFPNWZeeXQw Lego Pneumatic Engine. What is it? How to make it? The first it needs to finish Lego fake cylinder like in this video https://youtu.be/HcHneyewATE or https://youtu.be/0aZvWva41Ek. The second - to add o-ring to Lego piston like in this video https://youtu.be/wZu-l32Dajw or   . Edited July 30, 20186 yr by LegoEmbodiment

July 30, 20186 yr Best way to use of oxygen with your Lego Pneumatic Engine and truck!! Great job!!Â
November 30, 20204 yr Awesome job ! Did you use glue or modified parts ? Can you put several cylinders with different dead point so you don't need the flywheel ? Edited November 30, 20204 yr by Bluehose
December 1, 20204 yr Author Thanks! Yes, I used glue and drilled some parts. And I'm going to put several cylinder in order to see how it works together. Edited December 1, 20204 yr by LegoEmbodiment
December 1, 20204 yr Very interesting. In multiple cylinder engines one does have to make a crankshaft journal between each cylinder/cylinder pair though, to prevent the crank from bending.
December 1, 20204 yr I watched the video of this one, but, not understanding the language, I couldn't figure out how it worked. It appears that air is pushed down onto the cylinder head until the cylinder reaches the bottom, at which point it is sent out of the hole drilled down there. After that, though, I don't see how it could be pushed back up by the flywheel against the air. Besides, such a design would have no need for all the stuff on top of the block. Could you give me some more information please? Â Also, has anyone ever considered using a spray can of compressed air to run a pneumatic engine in a model?
December 2, 20204 yr Interesting working principle! Are you planning on creating a tutorial video at some point demonstrating how you made it?

December 14, 20204 yr Very nice, I like that you made it out of entirely Lego parts, except for the glue and lube. Why did you drill out the studs of the 2x2 brick though? Is that drill chuck Foredom handpiece for goldsmith's drill? I have the same, very useful tool.

December 17, 20204 yr Cool! I can probably scrounge a few of those valves, and I appreciate that this version doesn't require any rare Lego parts!
