The screw threads were cut on an Aureole thread milling machine and finished with a lathe tool. From 1932 the spindle and thread were made in one piece from KE637 steel. The threads were first milled using Holroyd thread milling machines, hardened, and ground using machines from the Coventry Gauge and Tool Co.[1]
