A scroll compressor is provided with idler shafts and scroll assemblies, both of which are two-piece assemblies. The two pieces of the idler shaft are made independently of each other and each includes an axis of symmetry which facilitates forming, or partial forming, of the parts on a lathe. The two parts, each of which includes a shaft, are then joined together with the shafts offset from each other to form the proper eccentricity in the idler shaft. The scroll assemblies are made by first forming a base plate for the desired scroll and then forming an eccentric groove in the base plate. An involute, which is formed to correspond to the groove is inserted in the base plate groove. The involute has grooves on both of its end surfaces to allow the same involute to be used for both the fixed and orbiting scroll plate.
