hi Blake i do get your point , how ever until michell sort out the bearing you will always have more noise in the bearing that is necessary , the surface finish is very , poor ,to the top of the being , where it sits in the cone is also that rough the ball does not sit properly , due to the ridges left after the use of what looks like a center drill, to get the ball to fit properly, it will either need to be lapped into the cone or the cone needs to be ground properly , i did the latter made the ball fit the cone , but only the bare minimum contact is needed, in my opinion this helps stop wobble, how ever i have not real proof only what i hear , also the ball NEVER rotates like a normal bearing ball, the pressure holds it into a fixed position , and rotates on a pin point contact only , the ball could be 20microns out of shape it would not make any difference at all, with the pinpoint contact may be half a micron out of round and then lapping it self into the tram line top of the bearing ,

may be if the top had been finished the same as the shaft it would be even less wobble and more central ,, with less rumble , as the ball is forced over the poor finish ,
