Rick, thanks for the interest again! Yes, any vise with uneven jaws in height (or with longitudinal clearances) can cause this and other position errors. As this device works with tangency points, it would be interesting to at least ensure that these points are reliable (or work with some type of templet as I have shown). Manufacturing tolerances must also be observed, in this and other cases.
A simple question, just out of curiosity: how did you check the accuracy of your center finder?
