Premium Norton 6 Inch Aluminum Oxide Bench Grinder Wheel - Fine Grit for Bench & Pedestal Grinders - Durable Grinding Disc for Metal, Wood & DIY Projects - Pack of 1 - Perfect for Sharpening, Deburring & Smoothing Surfaces

After reading all the bad reviews I searched for an answer and truly believe I found it! Craft Supplies USA sells what they call the Raptor R3X Grinding Wheel Bushing 2 Piece Set. This is a wonderfully made flange with an attached bushing that you can order to either fit a 1/2" or 5/8" motor shaft. It comes as two pieces, the flange with the busing is all one piece, and then there is another flange for the other side (I did not use this, but rather used the original inner flanges for the grinder). The bushing is 3/4" long, but will work on a 1" wide wheel without problem (the wheel I ordered is 6x1x1). I ordered two of these sets as the past owner of my 1920's grinder had ended up using just big washers as flanges on the outside of the wheels. I ordered the sets and then ordered the Norton wheel, so I was ready to go when the wheel arrived. I couldn't be more pleased!!!! I didn't waste time with the plastic bushings that were supplied as everyone seems to agree they are not the best. I pulled them out and stuck my new Raptor bushing flange in and put it on the grinder. NO WOBBLE as so many had described, and it was so perfectly in round that I doubt there is even 1/32" variance to be dressed (yes, I think it is less than that...maybe 1/64"). WOW! Very pleased! As far as shipping goes, I ordered the wheel alone so it would be all that was in the box from Amazon and not be bumping into other things. It was sent in a box similar to what Amazon sends books in, so there was no wiggle room in the box. It arrived in perfect condition. I truly believe the Raptor R3X Grinding Wheel Bushing 2 Piece Set is the answer...yes you spend more money to get a great bushing, but it is well worth not having to deal with so many issues on any grinding wheel you might buy that comes with plastic bushings.
