How hard is it to re-wire a grinder? I mean just the plug in part. I accidently cut part of the cord, so instead of risking my safetyness, I cut it right off so I couldn't use it. There is just 2 wires, black and white. If I get a 2 prong plug in, and enough wire. Will all I have to do is wire it up correctly? I need this grinder, its my 5" and my favorite one.
