I purchased a new lathe last year and until now haven't needed to make much use of the 4 Jaw chuck. During the week I needed to make some new main driver crank pins for the Simplex loco I'm refurbishing. Anyway, it needed the 4 jaw to ensure they were truly concentric. Running a 550 revs there was a noticeable vibration and the 4 jaw chuck body looks like its running eccentrically.
I decided to do some checks with the DTI but I've no idea what should be expected so here's a video of the results and I'm sure you guys are going to put me right.

DTI resolution is 0.0001" so each unit of major scale = 0.001"
