Checking run out on a part on the lathe and/or dialing in an adjust-tru type chuck or 4JC. Lathe in neutral I rotate by hand. After adjusting and getting what I think it within a thou the Indicator will not repeat to zero or high spot and low for that matter. Start at high spot zero the indicator rotate come back .0015" higher next rotation 001" low. change indicators same thing. change holders same, try the tenths indicator same. I'm beginning to wonder if it is the lathe. Maybe a bearing problem? I have no idea and it is frustrating. Spindle rotates freely and no noise. A little heat after high rpm's but nothing out of the ordinary.
Anyone else have a similar problem?
