Need Help on Orrery gears Answered
I'm planning on building an orrery and I need some help. I've been doing some research on instructions on how to build one. The main thing that I'm not completely understood with is the gears and how they actually work. I know a bit about some basic principles of gear ratios and stuff but not like the actual mechanism (ps i like to look at diagrams). I'm also planning on making 9 planets (i mean 8 + pluto and the moon and the sun). Any help would be appreciated, thanks!
