Stirling Engine.

Hi,
Recently while working on a Stuart Turner Henley steam launch I
have been playing with a Stirling engine. I am no expert on
Stirling engines, I have never made one, but have on occasion
managed to some belonging to a friend working. This engine was a
non runner and to be honest I didn't think it would work as it
wasn't made that well. Well after replacing some parts and
assembling I wasn't surprised when it didn't; at which point it
was nearly destined to end up in a box of 'might come in useful
bits.' But I thought; give it one more go, which is just as well
as I had forgotten to make a hole in a gasket to connect the
displacer to the power cylinder! This corrected first spin it
worked!!!
Anyway a bit of a video of playing this afternoon.

Have Great Christmas and a Healthy New Year.

Tony:
I just managed to find your post on the Stirling.
Well done; and I really like the cooling coil idea.
I may try it on a couple of mine.
Cheers,
Charlie

Very nice work. The water cooling coil is a nice solution, but I
wonder if it would run longer with air cooling if you used only
a simple alcohol burner? Those ceramic gas burners are extremely
hot. I also wonder if that plastic tube "linkage" is robbing a
bit of power, thus requiring more heat; would be simple to make
a 2-part jointed connecting rod.

You are possibly correct, I have little knowledge of Stirling
engines, I have only tried powering the engine with a ceramic
burner because it is easy to control, using a tachometer varying
the heat allowed the rpm to go from around 200 to just over 900.
I also wonder if that plastic tube "linkage" is robbing a bit of
power, thus requiring more heat; would be simple to make a
2-part jointed connecting rod.
This interesting type of coupling was what was fitted to the
engine when it was given to me, I didn't think it would work;
but it did, with seemingly little friction. You are probably
correct a hinged linkage would need less effort to operate, but
I rather like the different/unique? alternative.
Take care Tony.
