Such simple? I excepted to see something like many pipes with huge area of surface for better heat exchange.

Julius de Waal (not Julian) is a very prolific designer who has created hundreds of Solidworks models of varying complexity. This model, the Julian Traction Engine, is intentionally designed to be quite simple. Some others, such as his Allchin design, are full featured and quite complex. Many designs are not original, but instead are CAD versions of older paper designs. The Julian is loosely based on a Case prototype, but it basically freelance.

The point of un1corn's work and posting here is to showcase the use of FreeCAD to make the same models that have been made in Solidworks.

Congratulations Millenium-Gene. I always highly appreciate your contributions! Spot on for on- and off-topics. If I would ever had programmed FORTRAN I would have said: continue!

If you had programmed python you could say that as well

Apologies to Julius for mispronouncing and spelling his name.
In fact I have a passion for steam driven vehicles and machinery, and NO I am not living in the past, these engines have a character and strength of their own.
