making a working yarn spinning wheel?

I purchased a very convincing spinning wheel planter at goodwill for 6$. It is not an actual spinning wheel, but the components move, and i am convinced i can salvage this into an actual spinning wheel.... but i have no idea how to spin yarn on a wheel and therefor have no idea what i would need to do to rig this to work.

Any sites or ideas for creating a homeade spinning wheel? We can definately use the wheel, and the base. we just need to figure out a way to make the components work.
