Heat proofing the body, with sheet

metal and fiberglass insulation



I was able to use an old Cheddar Boiler, which was slim enough to fit inside the body, with just enough room for insulation. I used sheet metal and fiberglass insulation material toline the inside of the main body, to prevent the plastic body from melting from the heat. I used two Wilesco marine engines, and split the steam for each engine using heat resistant silicone tubing.



The steam pressure needs to be built up around 20 psi for a pretty short run. The gas fired flue boiler simply can not keep up with the thirsty demands of the two engines.



Gearing is very low, and R2S2 runs at a snail crawl.... However, R2S2 is still holds the record for the fastest steam powered R2 in any galaxy.
