No, he did not really. The two round 7 mm magnetic plates are namely exactly at the height at which the screws for the jaws of the vice are. Both are sunk a little, so that nothing survives what's ok. Unfortunately, this also means that the distance from the magnet to the docking of the jaws of the vise have each a small air gap, so that the actual maintenance is lost at least 50%. Solution: etc. The distance between the screw to the magnet by means of small washers reduce / make flush.
