U.S.S. Monitor Restoration

COLLINS MACHINE WORKS' on-site crew was selected to separate the propeller from the shaft of the U.S.S. Monitor that was recovered from the wreckage in 1998 off the coast of Cape Hatteras. Our on-site crew successfully performed the work on the very brittle artifact which can be viewed at the Mariner's Museum in Newport News, VA.
