Easiest way to say is I want it to work like a fan would, So the total movement would be around half a revolution, backwards then forwards, but at a slow speed.

I want to build a little motor combination that will allow me to slowly move an item on a pedestal, quarter of a turn one way then after returning to starting point go a quarter turn the opposite direction. I have seen a few ideas on other sites but no instructions how to make them. I guessing I need acouple of cogs and lever combinations to make it move back and fortyh. Can someone help. Thanks Mark
