This is with a PM-1228VF-LB lathe.
Seems that NONE of the chucks I have (and apparently even some I sent back to the sellers) are fitting on my lathe spindle correctly. I seemed to have problems whenever I would remove a chuck and then put it back on, as getting the runout to be acceptable was pretty much hit or miss. Well, come to find out that the chucks were not fitting flush against the spindle face. I put blueing on the spindle taper, and the chucks were catching right at the back edge. So depending on how I tightened the camlocks (D1-4) would have a BIG influence on the runout because the chuck just wasn't fitting flush against the spindle.
