Like all your models Chuck, absolutely wonderful.

They are the nearest to sounding and looking like an ic engine without being so that you will ever get, remarkable.

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?

Thanks Dick.  No, the mirror was ground and polished by Nova Optical.  It is a very good mirror.  Been looking at Saturn through it the past couple of nights.  Nice sharp images.
