Ship Propeller Drive Shaft
This shipbuilding site was known to have state-of-the-art equipment throughout its existence. Recovered from historic Union Iron Works Building 113, this massive drive shaft connected a ship's engine with its propeller, turning it with tremendous force.
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, steerin
apparatus, and piping.
