Compressed air engine
I've built a few air engines, I used a wobbler engine design you have a piston and cylinder assembly that pivots on a flat surface, the piston has a flat that essentially seals with this flat surface. The cylinder has one hole in it that let's air in and out, and the flat surface has two, one for intake and one for exhaust, as the crank rotates the cylinder pivots and lines up with each hole accordingly. For stirling engines you should look at marble displacer types, they are incredibly cool and I think much more interesting to watch. The only tricky parts are the graphite piston and the geared flywheel.
If you want I'll grab a picture or two of my marble displacer engine too.

jor2daje, I enquired in the lathe thread and I'll enquire again, any chance of seeing this little beauty running?

Beautiful engine, too bad I don't have a lathe
I've seen an engine like it but was made of wood. It is a good design. I think the type like I posted would be easier for me to construct, since I don't have a lathe or mill to make the flats. But I'm still deciding which to use.
For my stirling, I want to make an LTD and a candle one, but the marble displacer ones are interesting too. Makes a candle a bit more interesting

I have to join the discussion to point out that the simplest air engine can be built with an air cylinder and a 3 way valveIt's the same principal as my engine, only with three cylinder assemblies
Though a 5 way valve would be even better

Yep, cylinder connected to a crankshaft, at the end of the stroke hits the 3 way valve and the cylinder retracts etc, I can see it.POLAND_SPUD wrote:I have to join the discussion to point out that the simplest air engine can be built with an air cylinder and a 3 way valve

ohh btw now that you have a lathe you can build your own DCV valve... get a block of aluminium, drill a hole all the way through it then 3 perpendicular holes for ports and finally turn a spoolI can see it

I know, I know... but who needs it with a detent system? I have a 0.22" semi-auto on the drawing board with a blow-forward interrupter...POLAND_SPUD wrote:ohh btw now that you have a lathe you can build your own DCV valve...
