Tutorial for rigging mechanical things?

I have a couple of mechanical props I modelled, and I've never been able to figure out how to rig them. The one I most often use is a pair of glasses. The frame/lenses are one object and the arms are separate. I have the arms grouped under the frame and locked all the transforms except for the y-axis rotation, so they mostly function okay. But I'd really like to rig them so they're one prop (and can be made visible/invisible as one piece). Is there a good tutorial for rigging mechanical things with multiple parts?

Well, I do have a YouTube video on how to rig a door that is the same process you would use.

Thanks! That's a great tutorial. From it, I assume I can't use files I saved as separate OBJ files, correct?

DarkEdgeDesign has an excellent tutorial, too. It goes into great depth on creating content for Daz Studio.
