Cancer took dad in 2006, and shortly after that a fellow modeler named Jesse Livington published a Bernays model in Live Steam Magazine.
Jesse did a good job on the Bernay, and mentioned that he saw my dad's Bernay, and just had to build one.
Jesse's Bernay was smaller than dad's though, and was missing some of the finer details that I could see on the original engine, so I decided to make drawings for my dad's Bernay, and distribute them for free (as I do with all of my engine drawings).
The result are these drawings:
Here are 2D drawings I made for Bob's Bernay steam engine, and these drawings reflect the exact dimensions of Bob's Bernay engine, but are not a highly accurate representation of an actual Bernay engine. There have been quite a few Bernay steam engine models build around the world, and an...
Over the years, several have built Bernay's based on my drawings (which were based on my dad's build), including Vince B, who made the Bernay in this video.
At the time I made the Bernay drawings, I did not know how to use 3D modeling programs, and so the isometrics in my Bernay drawings are all made in 2D, and a little rough, but usable I think from a graphical standpoint.
As Vince B started to build his Bernay, I decided to use my drawings to try and learn 3D modeling, and so I modeled the Bernay in 3D, as shown below. I am not sure I 100% completed the 3D model for the Bernay or not.
And I made this animation in AutoCad to verify valve events. It is a series of GIF files that are played like a motion picture:
If you click on the image, it should play like a video, or it may do that automatically. (or you may have to download it, then click on it to see it run). I will make a video of it so it will run here.
