Thanks to everyone who has shown kindness and consideration in their complimentary posts, I am whelmed.
As promised this morning, here is a picture and a video of the mostly complete engine:
I think would make a much better banner photo so if someone with the power can make the substitution, I would appreciate it.
I will come back to this engine after I get #2 up and running. I haven't decided how best to mount them but I want to mount them on a common base. The other thing I would like to do is include a governor on this engine. It runs so well on such a small amount of air and responds to very small changes in air pressure that I think it should work well with a governor.
