LegoEmbodiment Posted July 29, 2018 (edited) 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, 2018 by LegoEmbodiment Share this post Link to post Share on other sites

Bluehose Posted November 30, 2020 (edited) 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, 2020 by Bluehose Share this post Link to post Share on other sites
LegoEmbodiment Posted December 1, 2020 (edited) 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, 2020 by LegoEmbodiment Share this post Link to post Share on other sites
nicjasno Posted December 1, 2020 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. Share this post Link to post Share on other sites
2GodBDGlory Posted December 1, 2020 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? Also, has anyone ever considered using a spray can of compressed air to run a pneumatic engine in a model?

2GodBDGlory Posted December 2, 2020 Interesting working principle! Are you planning on creating a tutorial video at some point demonstrating how you made it? Share this post Link to post Share on other sites
LegoEmbodiment Posted December 2, 2020 Yes, of course. Share this post Link to post Share on other sites

howitzer Posted December 14, 2020 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. Share this post Link to post Share on other sites

2GodBDGlory Posted December 17, 2020 Cool! I can probably scrounge a few of those valves, and I appreciate that this version doesn't require any rare Lego parts! Share this post Link to post Share on other sites
