a moveable mount;
a driven scarfing roll coupled to the moveable mount;
a scarfing roll lifting assembly coupled to the moveable mount;
a first sensor configured to sense contact between the scarfing roll and an external surface;
a second sensor configured to sense position of the scarfing roll when information is received from the first sensor that contact of the scarfing roll with the external surface has occurred; and
a control unit programmed to operate the scarfing roll lifting assembly to position the scarfing roll at a desired scarf gap measured from the contact position.
