Trying to get the movable jaw assembly separated from immovable jaw. Unscrewed far enough but the slider is very tight and does not want to come off. Should I just spray with penetrating oil or diesel and keep pounding to separate the halves? The threaded portion is out of the guide in the back of the non-movable jaw but I know know how hard I should expect to pound it to get it out. It needs some filing to square off edges and perhaps a couple small bulges that are holding removal back.
