Way too pretty, neat, and clean!

What is your method for getting "ground" to the work?

--Rotary table will sit atop my steel welding table. Motor section
will be isolated from the rotary section via the rubber connector in the
Lovejoy connection and from the welding table with a thin piece of rubber or
plastic or even wood.

--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.

Nice Work!

Here is a pair of them that I built a few years ago.

Looks nice.

One question -- what happens if the carpet tape gets hot?
Depending on the current, the carbon brush may get quite hot.

Enjoy,

--Welll let's call it a calculated risk.. ;-) If it fails I'll maybe
switch to a piece of circuit board material. Whaddya think?
