I'm refurbishing a South Bend 13" toolroom lathe. Currently, I'm working on the quick change gearbox. Some of the bronze bearings were sloppy with about 0.009 clearance, so I bought a bunch of generic bronze bearings from McMaster. Have made a threaded tool and removed all the old bearings. Just now I pressed in the first of the screw shaft bearings, but now the shaft doesn't fit. Specifically, I bought a bearing for a 1" shaft, and it barely slid over the shaft before I pressed it in. Now that it is in place I find that the shaft is about 0.998" and the bearing is about 0.997". Now I wonder, is it expected that those bearings need to be reamed after pressing in place? If so, do I ream them to 1.000" (providing about 0.002" of clearance), or do I need an oversized reamer? Is there another (less pricey) way to adjust the bearings to fit the shafts?
