This is the first run of this engine using steam. I have previously had it going on compressed air, but there is nothing like real, live, hot steam!!
It did show up a few problems which I will have to fix. A few minor leaks, need for a displacement oiler, and need to adjust the length of the piston rod. You will hear a knocking sound in the video. I think that is due to the piston just touching the cylinder cap at the end of each stroke. Not difficult to fix, but will require a complete teardown of the cylinder=piston.
