After working in London's Woolwich Arsenal as a skilled blacksmith and toolmaker, Henry Maudslay (1771-1831) joined the famous locksmith, Joseph Bramah. By 1797, Maudslay had started his own busines producing machine tools, and developed two extremely significant tools - a highly accurate screw-cutting lathe and the slide rest lathe. Both were used to develop other precision tools, in particular the machinery used in the production of ships blocks. In 1810, he moved his works to Lambeth, starting the firm of Maudslay, Sons and Field with Joshua Field (1757-1863) to make machine tools and marine engines.
