Abstract
Abstract A method of positioning a generally vertically extending positionally adjustable tool-driving head of a machine, such as a milling machine, at a predetermined direction includes providing a base and fastening it to the head, positioning a flat smooth surface of the table normal to the predetermined direction, freeing the head for lateral movement, and causing relative motion between the base and the table until they engage one another and the base is seated flat against the surface of the table.
