A millwright works to install, assemble, and disassemble equipment and machinery in an industrial, manufacturing, or construction setting. As a millwright per diem, you perform your duties on a part-time or contract basis. You are paid per diem, which means your contract stipulates a set pay rate for the day. Your responsibilities include the installation and maintenance of machinery for fabrication or other manufacturing processes. You read blueprints and plans to determine the method for repair or assembly of the equipment. You also schedule maintenance and analyze newly assembled or repaired equipment to ensure proper functionality.
