Nice setup. You stole that Baldor grinder at $25! If you keep a wire wheel (or polishing wheel) on one side, you don’t need the tool rest on that side, nor should you use one. I learned the hard way, having a bolt that I was cleaning get sucked in between the tool rest and the wheel. It stopped the grinder, made one heck a noise and it scared the heck out of me. Fortunately neither me or the grinder suffered any damage.
OSHA has requirements for tool rest on grinding wheels but none equipped with a wire wheel.
