Orrery

[Kactiguy]

I came across this video this morning. It's not an engine, but it could be hooked up to one. Besides, it has gears and machining and stuff.

So that is how it works! And all this time I have been thinking the planets were just suspended in space and floating around.

By the way, pouring that brass looked a little sloppy and dangerous to me. He must have got his training as a Bar Tender. Oh, well. I guess it works for him.

Cool!

I've been working on an orrery design off and on for some time that's inspired by the Antikythera Mechanism the Ancients built. Here are a couple of drawings:

A schematic of the gear ratios required.

The planets...

Base plate...

This one will wait until I get really good with CNC!
