To thrive as a Millwright Helper, you need a basic understanding of mechanical systems, hand and power tool proficiency, and often a high school diploma or equivalent. Familiarity with equipment like hoists, forklifts, and measuring instruments, as well as certifications in safety practices such as OSHA training, are commonly required.
