The apron was fitted with heat-treated gears with their studs supported at both ends. The handwheel-operated gears which drove against the bed rack all ran on roller races which gave the carriage an easier feel, especially when chasing threads and attempting delicate work with a hand traverse. The control levers for the power sliding and surfacing feeds were on Monarch and CVA lines, with a powerful spring engaging a cone clutch on the power sliding and what the makers described as a "Safety angular tooth" on the cross feed. Both could be disengaged instantly by the cam action of the control lever, even when fully stressed under heavy cuts. If the feeds became overload, a safety device of the friction type eased the power sliding, whilst the cross-feed mechanism would automatically disengage itself. The whole apron was lubricated by a plunger-type "one-shot" system which provided enough oil for a whole day's working. A boss on the right-hand edge of the apron carried a lever which operated the headstock clutch and spindle brake - an ideal arrangement when the operator's position took him towards the tailstock of the lathe. The direction of the carriage movement could be reversed by a lever, operating a double bevel within the apron, without stopping the lathe or having to reverse the direction of rotation of the feed rod.
