How did Henry Maudslay help manufacture Bramah locks?

Because the Bramah lock was highly intricate and expensive to produce by hand, Joseph Bramah hired Henry Maudslay to assist in its manufacture.12

Maudslay, who served as Bramah’s foreman, worked with him to design and construct a series of specialized machines to produce the lock's parts mechanically. These prototype machines were among the first machine tools ever created for mass production, effectively laying the foundation for the British machine-tool industry. By enabling the precise, mechanical fabrication of complex components, Maudslay’s engineering contributions were essential to the successful commercial production of the otherwise difficult-to-manufacture Bramah lock.123
