I want to build some stuff with gears, like a gear box or this: http://www.engadget.com/2010/12/10/apple-engineer-uses-lego-to-rebuild-ancient-greek-mechanism-wil/ What parts do I need to buy and where can I get them? I can't really find what I'm looking for. I've been to BrickLink.com and found the 871 Expert Builder/Gear Parts set, is this what I should get and is there anything else? Or is there something besides Legos that I should use? Thanks, Adam
