Orreries come in all shapes and.
Build a solar system orrery.
I have always wanted to build a working model of our solar system often called an orrery but was never able to find a design or set of plans that inspired me.
An orrery is a mechanical model of the movement and position of the planets in our solar system.
Orrery a mechanical solar system model from plywood.
It shows you the relative positions of the planets in the solar system during a given year and month.
Create a matching set and showcase your working model solar system orrery and orbiter together.
This instructable is about how to build a desktop orrery.
This project explores the use of plywood to make mechanical decorative and structural parts.
And like a globe an orrery also serves a practical function.
