An electroforming process developed for obtaining nickel shells of acceptable quality for structural tests is described. The discussion covers the composition of the plating bath, the preparation of aluminum mandrels (using silver as the releasing agent), the plating of aluminum mandrels, the removal of shells from aluminum mandrels, and the preparation of wax mandrels. The shell specimens obtained by these techniques have identical inner diameters, similar mechanical properties, and are free from residual or internal stresses. The variation of the shell thickness does not exceed 3%. The samples obtained were 10 in. long, 0.004 in. thick, and had an inner diameter of 5.274 inches.
