An apparatus includes a vibration isolator which incorporates at least two disk spring washers. Each disk spring washer has at least one ring-shaped outer spacer coupled to the outer edges of one or two of the disk spring washers, and at least one ring-shaped inner spacer coupled to the inner edges of one or two of the disk spring washers. A bottom attachment portion supports the disk spring washers, and a top attachment portion, with an application of a downward preload force, compresses the disk spring washers. A compression fixture applies and holds the preload force to the top attachment portion, and a second top attachment portion, with application of an additional downward force, further compresses the at least two disk spring washers.
