Some call it a solar engine, others hot air engine, I prefer to call it by it's inventor a Stirling engine.
Today a Bing Stirling arrived and it was in pretty good condition some dust and dirt over time but that is normal.
Only the burner house and chimney suffered from some surface rust, so that had to be cleaned and the steel re-blued.
This is how it was advertised…

The red bace plate was something to loose first.
The complete engine was taken apart to give all the parts a good clean.
After a reassembling and oiling this was the result…




Than the function test…

A similar engine wit different print.

Very nice Danny, I like your brick/stone background.
Another fine restoration Danny.
Thanks for posting the great videos and pictures.
Danny, a nice job of restoring, even if quick. I have never seen such an old Stirling run well...congrats, beautiful pieces.

Wonderful Stirling engines you have there Danny, and a fine gentle restoration of your newer addition.
You are quite right to call these Stirling engines, but let me clarify that when some of us refer to them as "Solar Engines" we are in fact referring to one specific manufacturer who made several models of Stirling engines, and that would be "Solar Engines of Phoenix Arizona", many of whose designs are now made by PM Research.
Now they did make a solar powered Stirling engine which was called the "Sun Motor", and that PM Research now calls the "Sun Runner", so those truly are "Solar" engines and Stirling engines both at the same time. Well anyway, I hope this helps clarify the obviously somewhat confusing use of the term "Solar Engines" in reference to some Stirling engines.
