An Operation & Maintenance Manual is available for this miller

Part No. 21: Universal Milling Table swivelling in three planes. With a clamping surface of 680mm x 230 mm and able to be tilted 45--0--45 in the vertical plane, 35--0--35 horizontally (front to rear) and swivelled left-to-right 45--02--45 this was the most versatile and desirable of the various fittings available and allowed the miller to be used to the limits of its extensive versatility. Like all of its kind (with so many clamped surfaces between workpiece and cutter), only relatively light cuts could be taken if flex in the assembly was to be avoided. Three centering dowels were provided and three 10 mm wide T slots on a 52m pitch.

Part No. 20: Plain Tilting table. 680 mm x 230 mm clamping surface and able to be tilted 45--0--45 in the vertical plane. Three 10 mm T slots on a 52 mm pitch were provided.

Part No. 22: Rigid Angle Table. 680 mm x 230 mm clamping surface with 10 mm T slots on a 52 mm pitch. This table, being secured by 4 bolts in the horizontal slots and of greater mass than the others, was the best option for heavier work.

For production work lever-feed controls were available for the longitudinal and traverse (head) feeds

Part No. 24: Universal Dividing Dead for Spiral Milling Incorporating Differential Indexing. This versatile 105 mm centre height unit consisted of a set-over tailstock and a headstock able to accept the ubiquitous W20 Schaublin collet. A set of 4 division plates was provided (in a fitted case) and 17 gears. 

Part No. 24: Plain Dividing Head with interchangeable indexing plates and a spindle nose to accept Schaublin W20 collets. Quick and easy to use the unit had a 130 mm centre height  The tailstock (Part No. 25) was listed as an extra.

Parts No. 27, an Auxiliary Swivelling Base for dividing heads (with a single T slot down its centre) and, mounted on it, Part No. 26: the Universal Dividing Head for Direct and Indirect Indexing with a 95 mm centre height . This accessory was supplied with both a 60-tooth direct indexing plate and a worm gear unit with four diving plates

Part No. 32: Die Milling Attachment. This popular accessory used a system of eccentrically mounted plates (with a suitable locking device) that allowed any point on the top plate to be accurately located over the axis of the spindle. In use it had to be attached to Part No. 33, the Swivelling Dividing Attachment (see below), and was used for the production of dies, cams and other items incorporating a combination of arcs and straight lines.

Part 33: Swivelling Dividing Attachment with the Die Milling Attachment, Part No. 32, also mounted.

Part No. 58: Dial Gauge Holders and Slip Gauge Troughs (for longitudinal, transverse and vertical feeds) and Part No. 59: Dial Gauges calibrated in increments of 0.0005" or 0.01 mm

Part No. 57: Centring Microscope. This 30X unit was supplied in a fitted case.

Elegant handwheels with a satin-chrome finish on the zeroing micrometer dials
