He eventually moved south, and worked for Henry Maudslay before founding his own precision engineering company in 1808 in Soho, London.

The company produced machines for bullet-making, gun-boring and turning for a number of government arsenals, as well as coin-weighing machines for the Bank of England, two-cylinder printing presses (designed to print simultaneously on both sides of a sheet of paper) and a centrifuge for sugar manufacturing.

His machines were described as "delicate as any clock could be",[1] and his printing press in particular earned praise by Thomas Curson Hansard.

After his death his grandson Montague Napier, would make the company famous for first motor vehicles and later aero engines.
