gridley51's comment is correct but your hard jaws should be better than .005" off. Are they numbered and in the correct location? If they are not numbered label them so you know which is which, and then move them around so you have tried all combinations of the jaws in different locations. You might find one thet runs truer so then you mark them permanently to stick with that position.
Oh, of course, the simple check...make sure the serrations are clean.
An open mind is a virtue...so long as all the common sense has not leaked out.
