Initially hired as a shipbuilder, he soon discovered other opportunities to use his talents as an engineer and inventor, constructing industrial machinery and experimenting with steel production.These were built by the shipyard of Hobbs & Hellyer at Redbridge, Hampshire, and incorporated a number of other novel features such as interchangeable parts for masts and spars, allowing easy maintenance while at sea.[Note 1] In March 1796 Bentham was appointed Inspector General of Naval Works, responsible for the maintaining and improving the Royal dockyards, a post which involved a lot of travel.[5] In 1805 Bentham returned to Russia, this time on government business, and remained there for two years with his family, chartering an entire ship to take his establishment, his servants and his companions.Samuel's mission for the British government in Russia was blocked by constant obstacles and he returned home in 1807 without having achieved any of his official objectives.One factor in their decision was a threatened lawsuit from neighbouring farmers, who claimed that Bentham's irrigation system was diverting the local water supply.
