A short while back I joined this group and enjoy it very much. I have been an artist for a long time. (I'm 79 years old) One of my other hobbies since my early 20's it building miniature engines, that run. Originally I would purchase rough castings but later started designing my own. I have build many types and configurations over the years. Most can be found on my Youtube channel under gbritnell. The one I am attaching picture of is a 1/3 scale Ford V-8 engine. It took about 3000 hours to build.
