This is a follow up video. For the small steam engines, I moved the pipe partially out of the beam BECAUSE these small engines do not consume the steam fast enough and the hose pops off. This trough alone is much better for preheating.

This is a thick Mylar based parabolic mirror with a 40 inch effective area. The focal length is adjustable with vacuum power. It produces amazing optics and may be an option for a Dobsonian Telescope. The part C material is a first surface mirror on one side and second surface on the other. We coat the first surface with an enamel spray as water can remove the mirror. Once coated it is weather proof. We also use the second surface for solar. FOCAL LENGTH 5000 MM TO 8000 MM. I left this a bit baggy but with a good stretch, you can make a 15M FL.
