Bolt shop

This shop produced a range of products, including nuts, bolts, rivets and wheel spokes, which were used within the works and sold externally. It was a noisy place, with most of the fast-paced work done by people at machines.

Fitters and turners made bolts by cutting iron bars into the required length. These pieces were heated and rounded at one end using a swage die. The bolthead was formed at the opposite end using a different die. Sharp edges were then removed and tips and threads added. A nut was then screwed onto each bolt. To produce a hard finish, bolts were heated in a furnace then rapidly cooled in water. From the 1920s women were employed to do some of these tasks.

Rivets, nut and bolts

All rivets, nuts and bolts on the harvester, such as these square-headed bolts, were made in the bolt shop.
