Question Gounding Old Motor

I am in process of refurbishing a very old Delta scrollsaw. The 1/4HP motor (also Delta split phase) does not have a grounding wire which makes me very uncomfortable! Can I simply rewire with a 2 wire plus green ground wire cord and ground the motor end to the frame somehow (wire inlet cover for example)? I realize that I would have to remove paint to be sure of good contact.

Well if this was a new motor with grounding means it would be in the wiring enclosure either by green screw to frame or green wire to frame. Sooooo I dont see anything wrong with what you propose. IMO it would improve the safety of the tool as long as it is plugged into grounded wiring.

There a a lot of double insulated tools out there that dont require grounding, however this being an old scroll saw it would not be this way.
