By using a system normally only found on better classes of toolroom lathe, with a speed-change gearbox in the cabinet stand and the drive to the headstock spindle by belts, the makers had taken unusual care, for a general-purpose lathe, to minimise headstock vibrations and gear-tooth chatter marks on workpieces. An all-lever and dial-change, oil-bath screwcutting and feeds gearbox was fitted - with no open slots to allow in swarf and dirt. A very similar larger version was also produced.

Fitted with a standard-fit 4-way toolpost, the top slide was clamped down by four bolts to a full-length cross slide that, unusually on this size of lathe, incorporated two T slots in its rear surface for the mounting of a cut-off or other type of toolholder.
