Very Nice,

If you can do it, I would like to see a video of it running.

Thank You for the video. That is running very well. I like the sound, whether it is running slow, or whether it is running fast.

It was a fun little engine to build. I'm currently remaking the crank from bar stock as the one I used was built up from drill rod and some key stock. I'm hoping that the one piece crankshaft will turn a little truer than the built up one. Fingers crossed, it's a bit fiddly when it's so small and the throw is so deep. I had to take it to work to do on my breaks as I found my mini-lathe too small for what I was trying to do. Tailstock didn't come out far enough to give me the room I wanted, but the 18" lathe at work has plenty of room.
