Stirling Engine

Postby ppemawm » Sun Sep 22, 2013 9:26 pm

This is an example of an assembly that was created with FreeCAD. It is a complete Stirling Engine.
All parts were created in one file from machining drawings, found on-line, basically in the order of assembly sequence.
All fasteners complete with accurate threading were imported from McMaster Carr STEP files.
The file is 3.84 MB, mostly due to the fasteners.

ppemawm,
The machining drawings came from this link http://www.john-tom.com/html/SteamPlans3.html?
Stirling Engine by Jean Fernand.
I teach machining and would like to use the designs in practical classes.

I stumbled across this old post (when I chased spammers). The links to the images are lost. We have seen here your great models so I would ask, if you still have the images and if you can upload them here again.
You need at least FreeCAD 0.19.23300 to edit my current sketches.

Agreed! Thanks for asking @chrisb

Thanks chrisb.
Done.

I am not sure if these are the same but they were in my file with the model.
Wow, look how far FreeCAD has advanced.

Very nice!

BTW, the correct spelling for the name of the inventor is Stirling.

Good catch...it seems my spelling is either common error or common use for the engine name. Take your pick.
In any event, I corrected the post.

Thanks for adding these. I can see that you used groups to organize the model, sort of making your own body predecessor.
