Here's mine.
The launch engine was my 2nd engine. I thought it had gone well until someone pointed out my slitting saw was upside down and I had rubbed the grooves in the valve rather than cutting them.
The mill engine was my 3rd engine. It's probably my favorite. It works.
I pretty much go by plans but am trying to develop a little..."make it mine".
Zee, I remember when I started my #43 Mill Engine build that you said it was one of your favorites. When I got finished, I'd have to say it was the same for me. Learned a lot from that engine build. I think it's time for another Elmer's engine.
