Some of these movies don't work yet... Beyond my steam comprehension!
If you click on these pictures your browser should open up your media player and you will see a movie of the engine turning over from different aspects.
If the clips won't play see the bottom of this page
The engine is driven by an electric motor under the bench in all but the last two clips.
In the second last clip the engine is running on air supplied by a 12cfm compressor. It does not run well as the cutoff necessary for efficient steam consumption is about 65% of the stroke. When running on steam the continued expansion of the steam continues to drive the piston down but on air that is that.
The first 4 videos are poor quality due to the size of the file necessary for high quality images and there is no sound as the captured sound from the tape video player is very faint.
The last 4 video clips were taken on a digital camera, are in QuickTime format and have sound!
They will take a while to download on a dial-up connection
The clips are short but you can make them last longer saving them and "looping" them in your media player
You will need RealOne Player to play the first 3 clips or maybe Quicktime for the last
