Inside the headstock-end plinth was a 4-speed-gearbox with its output directed through 5 V-belts and multi-disc clutches. It was driven by, through 5 V belts, by a 10 h.p or (optionally) 7 h.p. 2-speed motor.

The apron was a model of mechanical simplicity with the leadscrew clasped by twin nuts and the keyed power shaft passing through and driving a bevel gear that transmitted its motion to a set of spur gears. A single lever control on the face of the apron both selected and engaged the feeds and, because the mechanism did not become loaded under heavy cuts, it was possible to flick the drive in and out as required. 

The base of the speed-change gearbox provided an oil sump from which lubricant was drawn through a metallic-mesh filter and then pumped through a pipe to the headstock where it lubricated the headstock spindle bearings and gears. From there it drained down to the screwcutting gearbox first oiling the screwcutting gears and then, by collecting in a trough at the bottom and half submerging them, the power-feed drive gears. The overflow oil drained back to the speed-change gearbox passing through the gears before finally settling into the sump where the multi-disc clutches were located.

Both top and cross slides were adjusted with taper gib strips, carried ball thrust bearings on their feed screws and had clearly engraved zeroing micrometer dials with narrow knurled grip rings. The handles were traditional "balanced-ball type" which, whilst handsome, might have been considered rather hard on the operator's hands on a machine of this size.

With a No. 4 Morse taper the tailstock was correctly sized to the machine but the use of a direct-bearing screw to lock its spindle was unusual for the time when nearly every other lathe of this size had a compression fittings that squeezed it equally from top and bottom. The 23/8-inch diameter spindle had a usefully long travel of 9.5 inches but lacked either a graduated collar or ruler engravings to assist the operator gauge drilling and boring depths.
