Henry Maudslay championed the slide rest. This 1841 drawing by James Nasmyth shows how it allowed more accurate turning of metal components compared with older hand-turning methods.

Machines for all the world

Henry Maudslay revolutionised how accurate metal machines were made. You can see some of his machines in our 'Making the Modern World' gallery.

Maudslay developed ways of producing completely flat metal surfaces, accurate screw threads and new ways of measuring precisely to help create machines that were more accurate and reliable than ever before. Moreover, he trained others to use these new innovations as well.
