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.
