Sun Moon Earth

Build an orrery of the Sun Moon and Earth.​

An orrery is a mechanical model of the Solar System that illustrates or predicts the relative positions and motions of the planets and moons, usually according to the sun centered (heliocentric) model. It may also represent the relative sizes of these bodies; but since accurate scaling is often not practical due to the actual large ratio differences, a subdued approximation may be used instead. The first orrery that was a planetarium of the modern era was produced in 1704, and one was presented to Charles Boyle, 4th Earl of Orrery – hence the name. They are typically driven by a clockwork mechanism with a globe representing the Sun at the centre, and with a planet at the end of each of the arms.  From Wikipedia @ https://en.wikipedia.org/wiki/Orrery

Here are some examples of the custom colour schemes others have made

Check you have all of the parts

In the instructions the pieces are referred to by number. This diagram is to help you remember which piece is which. Take care when pressing out the pieces of laser cut wood.

1. Assemble the metal shaft inserting it into the gearbox axle – on the side with the notch. Using wood piece 2 this should go on top of the notch as shown.
2. Connect the wires to the motor.
3. Take wood piece 4 and wood pieces 6 (both of them) and mount the gearbox as shown.

4. Secure the gearbox in place with wood piece 7.
5. Take the legs – wood pieces 1 and attach as shown (it’s easier to decorate them before you assemble them).

6. Create the base using wood piece 5.
7. Attach the large tooth outer ring to the top of the main disc. Use wood pieces 3 to secure.
8. Using wood piece 13 (small cog) line up with white gearbox axle and push into place as shown.

9. Using wood piece 9 secure the cog down.
10. Using one of wood piece 14 and 15, slot together as shown.

11. Using wood piece 14 and 17 slot together as shown.
12. Using the step 10 piece insert that into wood piece 11.
13. Using the step 11 piece insert that into wood piece 12.

14. Using step pieces from 12 and 13, insert them into wood piece 10 as shown. The gears should mesh together.
15. Insert wood piece 14 into step piece 12 (it’s a little arm). Secure step 13 cog into place with wood piece 8.

16. Add the moving arm onto the shaft and secure with an orange disc. The large gear should mesh with the outer gear.
17. twist the wires from the battery box and the gearbox togethor.

19. Add the Sun, Moon and Earth balls as shown. Secure the battery box on the base.
20. Your ready to go!
