i love steemengines, as a boy i have build one when my mother would not buy a ready made model from the toyshop I could not let the idea go, I made one from scrap and found objects, asked the local plumber store for thin copper piping. I wanted a nanometer to measure the pressure
The final project did not look like the ready made steam engine but it worked. Later this project transformed into a distillation engine to make my own alcohol to fuel a motor.
