Roberts then found employment as a patternmaker at Bradley Iron works, Staffordshire, and, probably in 1813, moved to a supervisory position in the pattern shop of the Horsely Iron works, Tipton. He had gained skills in turning, wheel-wrighting and the repair of mill-work. He was drawn for the militia and to avoid this made for Liverpool, but finding no work there shifted to Manchester, where he found work as a turner for a cabinet-maker. He then moved to Salford working at lathe- and tool-making. Because the militia was still seeking him, he walked to London, where he found employment with Henry Maudslay as a fitter and turner.
