Engineer} To avoid a repetition of our trouble, all future steering rollers should be manufactured at RR. up to the stage of carburising, hardening and stress releasing. The final grinding can then be carried out by Hoffmanns. Will RHC{R. H. Coverley - Production Engineer}/Wld. please arrange for the operations to cover this. BY.{R.W. Bailey - Chief Engineer} | ||
