--Followup to followup: went to Sebastopol Dorkbot last night and we
talked a bit about grounding paths. New plan is to put a copper plate on the
bottom of the rotating table, then attach a 'wiper' of some kind to this so
that ground path will be thru the table rather than thru the bearings. More
photos after I've noodled it out a bit more.
