garson Posted April 16, 2011 Posted April 16, 2011 I just wondered if anyone else on this forum makes lego vacuum engines such as this http://www.youtube.com/watch?v=r31Ks30OHrM a creation of my own Quote
DLuders Posted April 17, 2011 Posted April 17, 2011 No, I don't think anybody else here on Eurobricks has made a vacuum engine like yours! You wrote on your YouTube video description (with added punctuation): "This is my redo of the three cylinder engine. The performance is much better. It can run well without a flywheel, but there's nothing wrong with a little flywheel. I have built a simple throttle mechanism. It does its job but i am now discovering the disadvantage of a Scotch yoke. Constant rebuilds of the yoke [are needed] because parts keep getting broken. The small pulley wheels are very fragile." http://www.youtube.com/watch?v=r31Ks30OHrM Quote
