Some Model Engineering related resources:

1. Engineering drawings of small model engines used for model aircrafts. They are designed for manufacturing and working, not not like showcase item. We can actually build them.

2. https://modelenginenews.org/midge/index.html

I went down a rabbit hole lately and found this article on tiny diesel engines built throughout the past decades, most of them model engines: https://modelenginenews.org/techniques/minid.html

> I've seen collectors turn a greenish blue and stammer out crazy offers on sight of my 0.1cc Nano, pictured here. But as the size goes down, construction difficulty and criticality of "fits" goes up exponentially.

This is great. If you enjoyed it you should check https://www.youtube.com/watch?v=8IEGmD_aV3w . Next to that it’s child’s play. That’s a whole trasatlantic’s engine room from scratch.

Related? Blondihacks [1] has been working through machining a live-steam powered scale locomotive.

Has it been three years now? She easily has another year of work ahead of her before she has live, rolling stock. Wild dedication to a project that could perhaps consume half a decade of your life.

Have to recommend TryAlly. He makes it look easy and straightforward. It's not.

https://modelenginenews.org/techniques/minid.html Mentions that this engine needs a spring start and 50% ether and it runs up to 40k rpm(!) seems like it’s finicky, which makes sense given its size
