Hey chuck, I've got a follow on question.  Do you think it would vibrate less if it had a 3-bladed propeller on it?  I agree with your choice to use the 2-bladed propeller as a 3-bladed propeller would be period incorrect, more, I'm just asking because I'm curious.  BTW, I had to come back and watch the video a 2'nd time.  I'm really liking this!  :)

Thanks for the kind words!  The type of propeller shouldn't make any difference.  Radials are notorious for vibration problems because of the mass of the connecting rod assembly.  I tried to offset that a little bit by machining a counterweight in the crank and frankly, I'm a bit surprised that the engine doesn't vibrate more than it does.

It even sounds like a real radial engine - truly a work of art!  By the way, did you grind and polish the primary mirror on your telescope?
