You need to saw off the waxed ends, run through a cutter to get the width right and plane the face to shape, shape shoulders and toe and maybe profile on a CNC and then cut splice, also cut a handle, pre press, bow press and finally fit the handle. Then you need to draw down the handle and sand and polish.
I know you've seen all this at GM and the sanding and finishing is the easy bit. Once you have a decent program on the CNC it is easy, just press the button....
