Help needed on a gear/cog project

HI all.


I am a complete novice when it comes to gear mechanics. However I am hoping for some advice or assistance in how i can go about a project i am working on.


Basically, what I want to create is something similar to this:

[ATTACH=CONFIG]621[/ATTACH]

So a planetary cog system which when operated turns the inner cogs. I want the big gear to be rotated from a smaller one on the outside. As shown in the image.


In effect, what I want to create is a phrase which, when turned slots back into place. See image below:
