In the course of chasing down a chuck not running true on my old delta lathe (1460 I believe), I checked it at the spindle.Carefully cleaned the inside M/T and tried 3 different #2 M/T centers. Measured with a dial caliper each center showed between .003 & .004 runout.
Would you consider this excessive?
I'd think a bearing replacement would be the only cure?
I've removed the bearings and measured and searched briefly for replacements but I've come up with some peculiar measurements.
2.050 .982 .660 thick?
Each one has C88505 marked on it.
Any ideas would be appreciated.
