another thing to check is deflection.
put an indicator at TDC on the chuck and insert a 1" x 12" rod in the chuck .
pull up on the rod and push down and note the indicators reading.
if you disengage the belt drive, and the gearbox- you may be able to feel faulty spindle bearings by turning the chuck slowly by hand.
there maybe drag noticed, if the preload is too great
