Building a running miniature rotary engine from scratch | Video

Think a rotary engine just isn't complicated enough for you? Why not try building a running version in miniature?

You can sit and watch the final components of this build come together, or you can skip to 10:57 to see it run.

Well... he didn't build a rotary from scratch.

What he did do, is take two production single rotor engines and make a 2 rotor engine. The eccentric shaft being the most important/ difficult creation.

Scratch building the rotors and housings would be wildly more difficult.

Where are the rotor side seals?

Model engines don't use them.

Crazy, but it works.
