Music Box Mechanisms

  1. May 6, 2003 #1
    Hi,Latly I have been interested in mechanical mechanisms and I'm looking for any information on the wind up music mechanisms which are found inside jewellary boxes (like the ones with the spinning ballarina inside), I would like to mainly know about the cylinder music mechanism (especially about how small you can actually get them, the length of time the tune it plays and its rate of rotation ie: to spin the ballerina) rather then the disc ones, any information would be greatly appreciated (I've come to my wits end on searching for more then a simple explination lol) Thanks :)
