330 mm (13") swing by 635 mm (25") between centres Harrison VS330TR

The carriage was constructed along traditional Harrison lines with a full-length cross slide and a top slide that swivelled through 360 degrees; both the saddle-to-bed fitting, and the cross slide were fitted with proper taper-key gib strips that allowed very fine control over their free movement and, as standard, the compound slide feed screws were fitted with dual-reading English/metric micrometer dials. The cross-feed screw nut was equipped with the same type of effective anti-backlash adjustment employed for many years on all he larger Harrison (and Colchester) lathes.

With no gearlevers to set, or belts to move - and hence no mechanical indication of the spindle speed - some form of digital speed readout was required; unfortunately, instead of being a large, clear unit angled so that the operator could read it without hesitation, it was a rather tiny, insignificant affair tucked away in the top right hand corner of the headstock's front face.
