Hi All, I have a project I am working on, I'd like to know if anyone knows of/or has seen it been done. I want a mechanism or method that allows me to change the direction of rotational motion that I am applying. For example, I want to rotate a crankshaft in one direction (say forwards), but want a fly wheel to rotate in the opposite direction. These need to be connected simply if possible. Anyone have any ideas or suggestions? Thanks!
