I am a beginner. Bought from Shars a 2” machinist vise. You’ll see in the photo the notches are not aligned directly across from each other. They start off close (not quite) and then become increasingly displaced, ending up a third of a pin diameter off from each other. Seems like a bug to me and so I should return. What a strange kind of manufacturing blunder. But, is it a feature of this kind of vise? Thanks. -Bill
