Mamod Se2a – Toy Stationary Steam Engine

There seems to be lots of minor variations with these engines – the one modeled has no throttle but does have a reversing valve, and a working whistle for letting off excess steam. The over pressure relief valve is at the top centre. I forgot to model the burner! Oops! Perhaps someone can do that for me! I modelled this to be powered by a solar concentrator (silvered satellite dish). I also wanted to understand the reverse mechanism better - Steam is cool!
