Picture of PVC Solar System

This instructable is the result of my son's school homework, At the end you will find a video in Spanish but I think it is very clear, so I will try to make a short summary here of the most important aspects of the video.

If any doubt please ask via comments.

What you need:

PVC Elbows
PVC Tees
PVC Pipe
Curtain aluminum pipe
Epoxy Putty
Lamp Kit
Bulb
Polystyrene Balls of different sizes
Wire

Size of the different components is not critical so you can adjust it  to what you have at home.
In my case I use 1/2” PVC pipe because I had some parts available.
The only critical size is the diameter of the aluminum pipe, as this should snug fit within the PVC Tee, if it is very tight the planets are not going to move and if too loose the supports for the planets will not stay in correct position.

Step 1: Suport for planets

Each planet is located in a support consisting of a tee, an elbow, a cap and two pieces of pipe.
The length of the pieces of pipe depends on the location of the planets and distance to sun (bulb).
The planets are fastened to the supports with a wire.
To fix the wire you have to drill a hole in each cap and I found that the easiest way to do this is with a piece of hot wire.
You must be very careful not to burn yourself when handling the hot wire is a MUST to use pliers and if possible wear gloves for protection.

Slight detail:
Pluto is no longer "a planet".
*sigh* Oh, how we miss you, Pluto!

You're right, now Pluto is a "dwarf planet", but my son insisted on including it.

¡Bien hecho! This is an awesome orrery, and the English instructions plus el video en español is an excellent way to make this accessible to everyone.

Check out how rimar2000 documents his bilingual projects. English and Spanish text make a project twice as useful.

Thank you, we have a problem with special characters in instructables since they don't look good, but either way I'll try to keep translating.

Any comments on the English translation or the contents of the instructable is highly appreciated.
