Electroforming mandrels used to electroform belts and the like are often fabricated from aluminum. These aluminum mandrels are very expensive. Before these mandrels can be used, they must be machined which is also expensive. While in use, these mandrels are often damaged physically and/or attacked chemically which render them useless. Indeed most mandrels are replaced because of physical damage which may be severe enough to cause them not to be reusable. There is a need for a way to repair the damaged mandrels.
