Anyone that is fascinated by gears owes themselves a visit to This Old Tony's video on YouTube titled "Gears! - But Were Afraid To Ask"

He goes into the nerdy depths of gear make-up, metallurgy, meshing, machining and mistakes as he manufactured metal gears on a mini-lathe.

I second TOT, his videos are just fun to watch. Plus, you learn something.

Going through his page, I immediately thought of his video on gears. Suprise! when it was mentioned at the end.
