When bevels are prepared with a reducing lantern and finished with a grinder, it is extremely challenging to maintain a precise angle.

Examiners are trained to think just what their eyes tell them; but when the examiner can not see the internal surface of the tube, it comes to be difficult to approve that circumstance.
