Iron Ship Fitting at the Royal Dockyard, Woolwich, 1854. Metalworking in London during the Crimean War. '...preparation of engines of the Termagant, 620-horse power...To form the cranks on the shaft, a quantity of scrap-iron is...put into the furnace, and when hot [is] welded under the 60 cwt. Nasmyth's hammer...when taken from the furnace and placed under the hammer, the heat of it is so intense that only those accustomed to the work could approach it. The shaft and cranks being forged, are finished in the Turning-shop to the exact dimension. The power transmitted through this shaft is equal to 1300 horses - more than double the nominal horses' power of the engine...[Here] a portion of the engine...is under the great steam-hammer; the operations are signalled by the workman on the left; and the heated mass is moved by the combined force of the several workmen on the right'. From "Illustrated London News", 1854.
