So I had found this WB that was in fairly decent shape except for the oversized hole which I thought I would use JB weld then drill out a 1/16" hole. All was going well when I thought I would spin it a bit on the polishing wheel. flew out my hand when I became distracted and put the chip in the edge...
It went from just under 8/8 to just over 6/8 after I ground it down to even out the edge.
