Hey everyone, I want to make a custom wind-up music box for my gf, and I was wondering if anyone knew anything on the topic?

I was thinking of just buying this: http://www.thinkgeek.com/geektoys/science/8f7f/
And then attaching a winding mechanism to it, and house it in something that I would craft out of wood.

Is there anyone who has experience in this kind of work? Or can point me in the right direction.

Thanks!
