Finished up the restoration of my Dawn 5SP Vise. Got the paint colour completely wrong but otherwise the new soft jaws and the jaw alignment works great. I made a transfer punch from a 5/16 UNC bolt to mark the position of the tapped holes on the back of the new Aluminium soft jaws. It has a 4mm hex milled to fit a 4mm socket that fits down a blind 5/16 tapped hole. A hexagon ER32 collet holder held the bolt in the 3 Jaw chuck on the lathe and for milling the flats.
