Arts & Crafts: Build your own personal steam engine.

I just discovered Pavel Chilin's YouTube channel. There's only five videos there so far but, my friends, they are glorious.

As near as I can tell, Pavel's love of trains has translated into his building a rat-rod-as-all-get-out  steam engine just big enough to conduct himself and a pal around a good length of track, which again, I'm guessing that he built himself (but please correct me if I'm wrong.) I'd love to see how much work it took to put all of this together if, for nothing else, it might lead to other folks to do it as well.
