All the gears in the headstock (and not just those responsible for the main drive as on less heavily stressed Colchester models) were hardened and ground finished on Reishauer machines. 16 speeds were available, from 20 to 1600 rpm and, because of the high top speed and the capacity of the lathe, the makers warned against other than the use of the dynamically balanced, ductile-iron chucks with hardened scrolls that had been specially commissioned from Burnerd.

Designed in conjunction with the British Machine Tool Industry Research Association the headstock spindle could pass a 3-inch diameter bar and had a hardened 8-in D1 Camlock nose.

The dual Metric/English screwcutting gearbox was totally enclosed, lubricated from an oil bath and fitted with hardened and ground gears running on ball-race supported shafts.

Three conventional levers - clamped to each of the three shafts at the top of the inner plate - together with a 6-position joystick that moved into radial slots around a circle, swapped the screwcutting gearbox ratios.

Double leadscrew clasp nuts in V-way housings.

The apron was doubled walled, with its shafts supported on ball bearing at each end and the gears all hardened and ground; the base was closed off to form an oil bath to splash lubricate the internals and at the top of the front face, just to the right of cross-feed screw, was a rod that pushed in to operate a plunger pump to feed the same lubricant to the bed, cross-slide ways and cross-feed nut.
The power feeds were selected by a push/pull button and positively engaged by a lever that allowed the feed to be stopped instantly regardless of how deep and heavy the cut was. A second push/pull button provided a means of reversing the feeds. 

Rear Toolpost mounted on a T-slotted adaptor plate fitted over the top of the cross slide.
