A compact clock, watch and instrument makers lathe accepting the 8mm horological collets in both headstock and tailstock spindles. Constructed from cast iron and steel, individually built and issued with an Engineers Test Certificate, the 90 CW is mounted on a cast aluminium base with integral thyristor speed control and is a portable unit. * Lathe bed - a one piece massive iron casting of cantilever form ground on all faces.
The bed has a central tee slot providing a positive and accurate location for the tailstock, incorporating a gap permitting the accommodation of large diameter clock wheels, total swing is 120mm (4.7in), the bed is in dovetail form.

A long tee slotted steel crosslide permits the mounting of accessories such as the Jacot (RG59) unit or Roller (RG53) filing rest, for example.
The crosslide has an etched angular scale 45-0-45 deg and carries the swivelling topslide to permit taper turning.
A quick change height adjustable tool holder is fitted.
All slides are fitted with full length adjustable gib strips.
Handwheels are steel and incorporate laser etched, re-set to zero calibration dials, clearly marked and graduated in 0.025mm increments.
* Tailstock - the tailstock is cast iron, bored and honed to accommodate the hardened ground steel barrel.
The barrel accepts the 8mm horological collet, which is secured in the conventional manner with a draw-in bar.
The barrel is lever fed to facilitate high sensitivity drilling.
Locking handles are fitted to both body and barrel.
