A method is described of fabricating a detail part for a superconducting magnet and also of fabricating a coil winding assembly for a superconducting magnet, comprising the steps of: (a) utilizing engineering specifications for a detail part to produce a master mold part for the detail part, while taking into account a calculated resin shrinkage factor; (b) utilizing the master mold part to fabricate a resin transfer mold for the detail part; (c) placing a preform for the detail part into the resin transfer mold and closing the mold with the preform therein; (d) injecting a two-stage curing resin into the resin transfer mold; (e) heating the resin transfer mold to partially cure the molded detail part; (f) removing the partially cured detail part from the resin transfer mold; (g) fabricating a coil winding assembly, while precisely positioning the partially cured detail part relative to the coil windings to produce a coil winding assembly; (h) placing the coil winding assembly into a curing press, and pressing and heating the coil winding assembly in the curing press, during which the detail part conforms to the coil winding and cures completely to produce a final coil winding assembly for a superconducting magnet.
