A single oil cup provided lubrication for the entire assembly. " This was an eminently sensible precaution, as it can often be surprisingly difficult to set up even a simple motor-drive system - and have it run sweetly and effortlessly - without first having to spend a surprising amount of time fiddling with alignments and belt runs.Ī control wheel on the front of the cabinet operated the system - and required twelve turns to change the speed from maximum to minimum. Interestingly, when the variable-speed drive was specified, the factory offered to fit the customer's own motor and dynamically balance the entire assembly, otherwise they "… cannot be responsible for vibration in your lathe. Although the larger lathes were required to have 3-phase motors, no such recommendation was made for the smaller machines, where 1-phase motors were considered adequate - that for the 11" being 0.75 h.p, the 10" a 0.5 h.p - and the 9" a 0.3 h.p. throughout its production run.įitted to the 14" lathe the maker's standard-specification motor was a 2 h.p. The 14" appeared to use the same range of r.p.m. whilst after this, the speeds were altered slightly to span 38 to 1400 rpm. The lower (motor) belt was 38" long and the upper headstock drive belt 60" long.ĭepending upon the year of manufacture the speeds available varied slightly and also changed with the particular model and the exact type of motor employed: for example, until 1956, the factory figures for the 12" lathe suggested a range in backgear of 38 to 295 rpm and in direct drive 250 to 1575 r.p.m. The motor pulley was fixed and the expanding and contracting pulleys fitted to a parallel shaft above.
