I hope the title grabbed your attention, now do please open the attachment and you will see the analogy. I have been working on this project of a rotary aero engine (circa 1908-1920) for a few weeks but seem to gone astray with the math co-ordinates for the rods, pins and pistons. So I am now opening it up to you good folk on the forum who may wish to collaborate, educate or fix my addled logic. When the brain is scrambled a second, third...nth opinion,may often see through the cloud.
It is actually relatively simple to make in wood and perspex but am trying to drag the animation into the 21st century.
This chap's site (done in animated CAD) shows the geometry I am trying to achieve in 3D. http://www.animatedengines.com/gnome.html
