A method includes mounting a hollow cylinder on a turntable, positioning an additive-manufacturing deposition tool at a surface of the hollow cylinder, and rotating the hollow cylinder on the turntable while depositing material on the hollow cylinder with the deposition tool. Further, a method includes making an opening in a wall of the hollow cylinder, forming a part to fit in the opening, and welding the part to the hollow cylinder such that the part fills the opening. The hollow cylinder has an inner radius and an outer radius, and the part is formed with an inner radius of curvature and an outer radius of curvature substantially similar to the inner radius and outer radius, respectively, of the hollow cylinder when the part is positioned in the opening.
