A couple of years ago I discovered your great website and it has been an inspiration to me. So much so that I went ahead and purchased a small lathe and mill prior to retiring.
As a new starter to model engineering I thought that the Monitor engine drawings from Julius would be a good start for me. Over the last year and a half I have gradually worked through making each component and finally completed the assembly last week. I have attached a video of the engine running on air. The significant hissing is coming from my control valve I made up, now resolved with a better fitting O ring, plus the pistons do not yet have piston rings. I just couldn’t wait to see if it would run anyway. Pretty happy with the overall result, I didn’t have to bin too many components and I took those mistakes as lessons.
Thank you for the inspiration and to Julius for the easy to follow plans.
