Precision Drill Vise

My vise came well packaged and protected in the mail. It is a hefty piece of equipment, well made. The screw moves freely. The jaws open and close smoothly and remain parallel throughout their travel along the vise bed. Problems: Both jaw faces were left with burrs of metal on their edges which needed to be filed off. This was not a significant problem as a quick few strokes of the file took care of the issue. A more troubling flaw is that the screws holding the jaw face in place on the traveling jaw are too long and protrude into the horizontal V groove by about 1/16" of an inch. To correct the problem I will need to remove the two screws, grind the ends of each one and then reinstall. The manufacturer should have used shorter screws.
