Well here goes the long story. I built a Stuart BEAM engine in ~1989. I learned about the "Watt's" parallel motion.
Studying this I found out about the Peaucelliar -Lipkin linkage that is "perfect" . I have always had it in the back of my mind.
So with time on my hands I did a search and found that was a link to Brian Rupnow's beam engine that a modeler suggested
Modifying his to this linkage. Well Don't know if he ever built one , but I have. I split the beam, flywheel in the center.
Frame instead of post. The Steam details are all clones without castings of the Stuart design. It is ball bearing crank,
eccentric, and beam. Delrin piston and packing glands. Made for air only. Super smooth. My pressure regulator gauge doesn't
even register when it is running. I am antiquated and use CAMBAM to make my Gcode so I have no fancy drawings.
But dxf if anyone is interested.

OK, Ved, I'm almost finished with the Contessa. What is your mind thinking of for your next project. One like this maybe?
