Screwcutting was by an oil-bath lubricated, Norton-type quick-change box with 40 English pitches and rates of feed available that spanned 2 to 28 t.p.i. The drive was taken to a 6 t.p.i. leadscrew, in high-tensile steel, held under tension by ball-thrust bearings at each end and grasped by double clasp nuts - the makers guaranteeing a total pitch error better than 0.002" in any foot of length for the assembly. The double clasp nuts were in gun metal and a thread-dial indicator was supplied as part of the standard equipment. As the box could generate only inch pitches, the makers offering the usual set of transposing changewheels to cut metric threads. Sliding and surfacing feeds were driven by a separate power-shaft though a non-adjustable, overload slipping clutch designed to protect the drive from ham-fisted operators. On the apron the power-shaft ran through worm-and-wheel gearing, a drop-out box providing instant engagement and, of even greater importantance, very easy disengagement under the heaviest of cuts - the mechanism being engaged by a single apron-mounted lever that also selected longitudinal or traverse feeds. Control of the feed direction was by the usual headstock lever that operated internally-mounted tumbler gears.
Fastened to the saddle's left-hand wings were long sheet-steel bed guards, these covering both the flat and V-ways and able to run on past the front and back faces of the headstock by passing into tunnels. Fitted with long wings to the tailstock side, but non towards the headstock, the saddle had its cross-slide ways positioned mounted to the left of the saddle's centre line - the necessary result of the bed ways stopping at the headstock's front face. Able to be swivelled through 360? the top slide was fitted with a simple "lighthouse" toolpost or, optionally, at extra cost, an indexing 4-way type in steel. Both top and cross-feed screws were fully covered and zeroing micrometer dials fitted - of rather small (but typical-of-their-era) diameter.
Fitted with a No. 4 Morse taper spindle equipped with ball thrust washers, the tailstock could be set over for the turning of slight tapers and was secured to the bed by a pair of pads and bolts, the latter needing the attention of the well-known self-hiding spanner.
Supplied with each new lathe was a complete set of coolant equipment (with the tank formed in the left-hand section of the stand), a 16-inch faceplate for the 8.5-inch lathe, a 20-inch face plate for the 10-inch, catchplate, a three-point travelling steady, hard and soft centres and the necessary spanners, handles and an oil gun.
Extra equipment included a 9-inch 3-jaw chuck, 16-inch 4-jaw chuck, taper-turning attachment, an extra-large 28-inch faceplate for the 8.5-inch model and a 30-inch for the 10-inch, metric translation changewheels, fixed steady with three bronze fingers, a set of twelve high-speed steel turning and boring tools, 4-position indexing 4-way toolpost in steel (that could also be locked down between the settings), tailstock revolving centre and a coarse-pitch screwcutting attachment that consisted of a sub-head mounted in front of the headstock that gave speeds reduced to the extent that even threads with up to a 6-inch lead could be generated. The attachment, which reduced the between-centres capacity by 16.75 inches, also incorporated a dividing mechanism that enabled multi-start threads to be cut.
The 8.5-inch model occupied a floor space of 10' 6" by 5' and weighed around 2.65 tons, the 10-inch occupied 12' 6" by 5' and weighed just short of 3 tons. Extra long beds on either model added 196 lbs per foot..
