I am starting a new thread for the Dake Steam Engine build in 3D, because the other thread title is misleading about who is actually designed this Dake (me), and who is actually building this Dake (me).

The story on this Dake engine is that my Dad saw some information about a Dake in an old Audel's book, as follows:
Dad came up with these sketches for his Dake build.
And this was the Dake that my dad built.
This engine runs very well, and makes sort of a slushing sound with it runs; not an engine sound really at all.

After my dad died in 2006, I got interested in understanding better how some of his engines operated.
I ended up disassembling dad's Dake so that I could fully understand how it worked.
Having figure out how a Dake functioned, I decided to draw a Dake in 2D.
My dad was a free-lance engine builder, and so his engines were basically his simplified approximation of the real engine.
I wanted a more exact Dake design, and so I studied a lot of Dake information, in order to create a Dake design that was basically exactly like an original Dake engine.
The result of my research is the following Dake drawings, which I created in 2009 and 2010.
These drawings are open-source, for personal and non-commercial use only.
These drawings represent a bar-stock-build of a Dake engine.

I started to learn 3D modeling in late 2012, and decided to create 3D models for the Dake engine.

The reversing valve on a Dake is very similar to a Westinghouse air brake valve, used on locomotives.
I started building a backyard foundry in 2012, and ultimately learned how to cast gray iron.
I ended up casting the green twin oscillator seen in my avatar.
Once you have an iron foundry, you start pondering what other engines you can cast.
Since my Dake design was complete, I decided to make patterns for that engine.

I bouught a Prusa MK3S 3D printer in late 2018, and started 3D printing Dake patterns.

I created a new assembly yesterday, to check the motion of all the parts.
I will run this assembly in a motion study to verify the correct travel of all the parts.

Here is a short video of Dake assembly in motion.
