This provides the linear movement for the valve gear to reverse without issue.\n \nI pulled the crankshaft bearing out of an electric screwdriver that was broken.\n\nEccentric bearings are 6806 2RZ bearings\n\nThere’s a lot I’d like to improve on this engine so that I might be able to release the files. but there are many issues currently that would make it hard for one to build and maintain.\n", "subreddit": "EngineeringPorn", "url": "https://v.redd.it/9rw4g4ot3enf1", "permalink": "https://www.reddit.com/r/EngineeringPorn/comments/1n9d6j5/3d_printed_steam_engine_model_runs_on_air_using/", "media": [ { "type": "video", "path": "reddit_data\\1n9d6j5\\video.mp4", "url": "https://v.redd.it/9rw4g4ot3enf1/DASH_1080.mp4?source=fallback" } ] }
