Patent ID: 8323076

Claim:
A backing plate for stabilizing and flattening an existing cut-off disc controlled by a grinder, said backing plate comprising: a spacer adapted to be positioned at a central location on an existing shaft of the grinder, the spacer having a distal face; a washer located at a top proximal central location of said spacer and being countersunk therein; a backing nut adapted to be mated to the shaft and abutted against said distal face of said spacer; and, a fastener adapted to be mated to the shaft in such a manner that said fastener remains equidistantly situated subjacent to said spacer; wherein said backing nut is adapted to hold the cut-off disc of the grinder against the distal face of the spacer and thereby prohibit the cut-off disc from being prematurely offset from a given plane during operating conditions.
