@@hotimchenko Most model vacuum engines have a stroke of about one and a half times the bore. Gulppin was an experiment to determine the characteristics of a vacuum engine with a short stroke to bore ratio. No plans were published.

Your vacuum engine is very nice. Thanks Tink Jim
Very nice and powerful. I’m not sure how these work but will find out. Thank you
Thanks for the comment. If you look up "Vacuum Engine" in Wikipedia, you'll find a very clear animation of the working of these engines.
@@DrTinkerJim Hello, do you have a drawing of this engine, I really want to do the same. Thank you.
