A method of repairing a downcoiler mandrel is described, in which worn areas of the mandrel body and segments are machined to dimensions suitable for accommodating bushings and half-bushings of pre-selected materials, the toggle links are machined in their pin areas to receive bushings of selected materials, and the outer arcuate surfaces of the links are plated with a hard wear-resistant metal, such as chromium. The overall construction resulting from such repairs and replacements is also applicable to the construction of new mandrels of this type.
