This shipbuilding site was known to have state-of-the-art equipment throughout its existence. Recovered from historic Union Iron Works Building 113, this press was used to drill holes (and even stamp markings and indentations) in fabricated parts.

Built in 1886, Building 113 (just south of 20th Street) is one of the earliest extant structures on site. From World War II onwards, it served exclusively as a Machine Shop, part of the shipyard Engineering Department. The work in this building was specific to fabricating a ship's propulsion and auxiliary machinery, steering apparatus, and piping.
