Oh the belt pinion comes off rather easily. The interesting part is getting something on that shaft... its an 8mm shaft with a flattened side. Set screws, I would not trust. I would make a broach for it. But thats just me. An interesting problem: how to do it cheap.

Has anyone used flattened shafts like this and know of a way to easily cut that into a gear? Or attach a gear to it some other way...?
