Well here are some pictures and video of my latest engine.
I got the idea from a picture I saw in "Home Mechanics For Amateurs" and thought it would be a neat engine to build.
There where only a couple of cut-away drawings, but no dimensions so I had to wing it. I modified the way the power cylinder is connected to make it easier to seal the one piece hot/cold cylinder.
I built the displacer cylinder from some 1.5" copper pipe, and after much searching found that a 42g can of Ronson Butane makes a good displacer piston.
HINT: Remove contents before using ;D
I just cut the top off to the right length and made a press-fit cap for it. Altough the copper pipe was easy to work with, It really was not a good idea.There is no insulation between the cold and hot sides so after 5 Minuit's of run time the thing is so stinking hot you could fry eggs on it :big: But at that point it is still running strong (550 RPM) and I shut it off for worry it will melt down!
These Hot-Air engines have got me hooked and I am already starting my next one: The Moriya engine.
Here is some video of it running
