At Cockatoo Island Dockyard Sydney Harbour

[ADMIN NOTE JAJ: From a Facebook posting proposing a description for this machine:
"The building of ships consumed vast quantities of rivets. The shipyard manufactured many of its own rivets using this and similar machines. Steel round bar stock was heated in a forge and then fed into this machine. The bar would be clamped, a head would be forged in the end, and the rìvet cut to length.
"Blanks for making bolts and nuts could similarly be made. The whole operation would only take seconds, before it was repeated again and again.
"The machine had adjustments and provision to hold different dies so that bolts, nuts & rivets of different sizes and shapes could be made. However machining and threading of the former two had to be done subsequently on a different machine. The shipyard would probably have purchased common sized nuts and bolts from a wholesaler, but specialised nuts and bolts for shafting, securing machinery and armaments could be made onsite." ]
