For my robotics arm project I have recently come across the following ball bearing at low discount price which I think could make a great rotary table for my arm.
However it does not seem to have any mounting connectors, and the inner and outer rings are the same height.
My mechanical creativity is a bit limited, but my goal is to drive (spin) it with a large stepper motor (I have 34 and 42 series available which, even ungeared, should be enough for my smaller arm). On top of the rotary table that I'm trying to create will sit a U-channel that will hold the rest of the robot arm. So in the bottom of that channel I will drill holes and connect it to... something.
If anyone could point me to, recommend, or create a simple design - I have access to basic metalworking tools and scrap aluminum - that would be absolutely fantastic. My main goal is to work with what I have: the bearing, stepper motors, aluminum, other things at a standard hardware store.
BTW, here is how I refer to the standard robot axes (of a 6-DOF industry bot) by name.
