I'm working on restoring an old camelback drill press. There is a thrust bearing on my spindle. It is a 3-part bearing. The outside 2 pieces just look like washers. The middle is like a washer only with several holes. In those holes go bearing balls. Pretty routine except mine is missing like six of the balls and the balls measure 0.3084". I cannot find anyone who sells bearing balls in this size. I have lots of 5/16" bearing balls which are only a few thou larger but I don't think they would work well because that's almost exactly the size of the holes so those bearings touch on all sides albeit not too tightly. No metric size is close either.
I may be able to source an entire replacement thrust bearing but it sure would be nice to find some balls that work.
I haven't tested the "ball plate" for hardness yet. If it were soft, I could ream them a bit larger and use 5/16" balls.
Ideas?
