Building a hand-crank mechanism driven turntable Answered

Hi there, Hopefully one of you guys should be able to help me out with this! What I want to build is a a kind of a large scale music box, (you know the ones where you would turn the wheel and the ballerina would spin?). What I need to make is a hand cranked machanism which will turn light wooden disc. This should all be contained within a wooden box. Would it be easier to build this from scratch or to rip an existing mechanism and re-house it?


I would look at planetary gear sets. how big did you want to make this? you could use a set of gears out of the rear axle of an older car or something.

Bevel gears make that motion ;)
